The story of how the Rolls Royce Merlin engine equipped the extraordinary P-51 Mustang and the evolution of the Focke-Wulf Fw 190's engine, all the way to the story of the first functioning centrifugal turbojet in April 1937, Frank Whittle's creation.
The Rolls-Royce Merlin is a British liquid-cooled V-12 piston aero engine of 27-litres (1,650 cu in) capacity. Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called Merlin following the company convention of naming its four-stroke piston aero engines after birds of prey.
After several modifications, the first production variants of the PV-12 were completed in 1936. The first operational aircraft to enter service using the Merlin were the Fairey Battle, Hawker Hurricane, and Supermarine Spitfire. The Merlin remains most closely associated with the Spitfire and Hurricane, although the majority of the production run was for the four-engined Avro Lancaster heavy bomber. A series of rapidly-applied developments, brought about by wartime needs, markedly improved the engine's performance and durability. Starting at 1,000 horsepower (750 kW) for the first production models, most late-war versions produced just under 1,800 horsepower (1,300 kW), and the very latest version as used in the de Havilland Hornet over 2,000 horsepower (1,500 kW).
One of the most successful aircraft engines of the World War II era, some 50 versions of the Merlin were built by Rolls-Royce in Derby, Crewe, and Glasgow, as well as by Ford of Britain at their Trafford Park factory, near Manchester. A de-rated version was also the basis of the Rolls-Royce/Rover Meteor tank engine. Post-war, the Merlin was largely superseded by the Rolls-Royce Griffon for military use, with most Merlin variants being designed and built for airliners and military transport aircraft.
The Packard V-1650 was a version of the Merlin built in the United States. Production ceased in 1950 after a total of almost 150,000 engines had been delivered. Merlin engines remain in Royal Air Force service today with the Battle of Britain Memorial Flight, and power many restored aircraft in private ownership worldwide.
During his spare time on the squadron and at CFS Frank Whittle gave much thought to the application of the internal combustion turbine as a means to drive the aeroplane propeller. As others had before him, he soon discovered that the levels of component efficiency in any suitable gas turbine engine would be dauntingly difficult to achieve. And then, as he would say in later life, “the penny dropped” and he perceived the possibility of using the high velocity/high mass flow exhaust to obtain propulsion by reaction. In doing so, he was dismissing the altitude limitations of the internal combustion engine and the speed limitations of the propeller. A practical form of turbojet was borne. An entirely new horizon for aeronautics was about to materialize.
Whittle worked on the business of the design of an engine with a potential thrust sufficient to propel a small airplane at very high speeds and at very high altitudes. He settled on an arrangement that incorporated a two-stage centrifugal compressor and a two-stage (Curtis) turbine.
He showed his idea to the station commandant, Group Captain Baldwin, who, perceiving strategic importance and a need for secrecy, sent him to be interviewed by the engine division at the Air Ministry. They in turn, arranged for him to meet Dr A A Griffith at the Royal Aircraft Establishment (RAE). Griffith had started seriously considering gas turbines for propeller-driven aircraft as early as 1926. In a meeting of considerable consequence, Griffith rejected Whittle’s proposals and convinced the Ministry that the idea did not warrant any further attention. Unfortunately, Griffith had his own agenda. He would have known full well that he would be instructed to work on the turbojet should he admit any serious practicality. Despite this setback, Whittle went ahead and applied for a patent - granted in January 1930. However, as the President of the Air Council declared that there was no need for secrecy, it was published in 1931.

Aviation Will Save the World from Itself! Maybe Even frankly whittle down the Lies that Divide!
All those square windows on early passenger jets, After causing decompression blow out crashes they finally figured out that a round window can survive many more cycles of high altitude compression/decompression. It's the little details sometimes that gets you.
It's rather sad that two great men, Frank Whittle and Nicola Tesla, were betrayed by so many, including the governments they dedicated their patriotism to. God Bless these great men.
Think it's likely Tesla was more messed up from doing his own work with very toxic chemicals/ fumes, etc.
It was disgraceful how Frank Whittle was treated..
Look at all of yous… dick measuring with all this back and forth Tesla this Frank whittle that…. Just enjoy the video….. anyone not enjoying this video is a sissy
@@chriswilde7246yes, the Brits and no doubt other governments treated many of their contributors badly like Polish Aircrew and Alan Turing.
@@Stuff-i-Like Totally agree...👍
I love this channel. I was taught so much about the various airframes of WWII. By a Tutor that I had for a few years around 1958-1961 ish. That early on knowledge turn into a passion throughout my life. That and my Stepfather was the owner of two C-47/DC-3’s and a Beachcraft twin that seated around 10? Passengers that took flights from Las Vegas to the Grand Canyon. Nevada Airlines. All of this past makes me very grateful for channels such as this.

I'm just glad this film saw the light of day and is now on CZcams. This is a video you SHOULD share with your friends.
The narrator incorrectly referred to the Grumman F4F as the Hellcat when in fact the F4F was the Wildcat. The much-improved version of the F4F Wildcat was the F6F Hellcat.
Enjoyed this video that took three days with roughly 3-1hr sessions to finish. My aunt's worked in the aviation industry both in jet engine blades and in aircraft manufacturing. I have worked briefly in the aviation field. Good to know the history behind it all.
I’d add too, that during the talk of radials being more reliable because of a lack of need to maintain coolant flow (which is completely valid by the way)
Kurt tank, the designer of the fw190 remarked that he thought the bf109 was a race horse. But since this was a war, he wanted to build a warhorse.
What I’m referencing is this: essentially all aircraft at this time were controlled by hydraulics. (Except noticeably not the Japanese zero, which was only cables, meant it was out classed at higher speeds) and for whatever reason did not have self sealing fuel tanks. So even minor hits would be problematic.
Anyways, building a warhorse. Flight control surfaces controlled electrically. Not hydraulically.
If it’s hydraulic, and gets punctured, that’s a loss of control authority.
Electric? You can have multiple lines running to the control surface. One gets punctured. No problem.
Warhorse, not a racehorse.
About 1 hour in: man!! Those late 50’s mechanics had their work to do. Very interesting video. My neighbor is a modern mechanic. I have to talk about the differences. Love the channel!
6:47 The little footsteps and odd random noises in these old black and white reels are hilarious.
i love Capn Brown, hes the real deal! Tough as Chuck Norris!
I love watching this stuff. I’ve been around aviation for years. I was an avionics technician on P-3s 50 years ago. Then I worked at P&WA a couple of years on the assembly floor putting together JT-8s and JT-9s. I wanted to work in electronics and moved to Alaska and had jobs for over 30 years where I was flown all over the state in many kinds of aircraft including helicopters. One of the customers of the engines I worked on at P&WA was Alaska Airlines and I flew on them a lot to hubs where I got on smaller aircraft. I worked for a contractor turning up satellite communications for the FAA all over the state including ZAN which is the control center for Alaska airspace for a couple of years. Also worked on the microwave communications for the pipeline for 15 years. Most of the sites were only helicopter accessible to mountain tops. I’ve been to quite a few of the military radar sites also. I got paid to do some pretty cool stuff. Now I’m 70.
🤠🎖🏅🥇
Cool stuff indeed. I like hearing about people's stories and experiences, and CZcams's ability to bring personal stories out of us never ceases to amaze me. Thanks for sharing.

Another amazing production!
The Jackals of Mediocrity always encircle and nip at the heels of the visionary.
All hype of inline engines in this video, yet the best aircraft of WW2 and post war piston engines were all air cooled radial engines. Such as Mitsubishi A6M "zero", Gumman F6F Hellcat, Fock Wulf FW190, P-47 Thunderbolt, B-17 Flying fortress, B-25 Mitchell, B-26 Marauder, B-29 Superfortress, all the way into the Vietnam war era with Douglas A1 Skyraider, and B-36 "Peacemaker" with its 6 radials and 4 jets that led to the B-47 jet.
wasp , double wasp
Fock wulf….😂😂😂😂😂😂
Another great couple of documentaries 👌 👏
The US Navy was biased towards the radial engine primarily because of its reliability, ability to operate with battle damage that would have brought down a liquid-cooled inline engine, and its ease of maintenance. Those were critical attributes when operating from an aircraft carrier and over water. Radial engines also evolved superior power to weight ratios than inline engines.
The Army Air Force was less concerned about those positive attributes and valued the reduced frontal area of inline engines and its potential impact on drag. Frontal area was more a perceived issue than a real one. Liquid cooling provides its own drag penalties and both the radial-engined Focke-Wulf 190 and the Vought F4U Corsair benefitted from NACA radial cowling drag research to become two of the fastest single-engined fighters of WWII.
i watch greggs aeroplanes as well
LOL@@billynomates920 brilliant
@@billynomates920 Greg's is great! However, I'm 77 and the son of a WWII and Korean War carrier pilot was also an engineer. I acquired my opinions from someone who was there.
What a fantastic deco, thank you, keep up your great work 😊
although it’s crazy to think US Navy destroyers have four jet engines inside them, not including the three generators for a total of seven jet engines inside a destroyer
Crazy. Slurp fuel. Should've been like USCG. Use combined diesel and gas turbine.
Dronescapes is some of if not the best content.
Commander Eric Brown (RIP), was an Tremendous professional and Pilot. The more I learn about the things he did During His life the more incredible are his accomplishments. Brown and Galant both are the epitome of aerial fighter pilots.
🤠💯
He was a Navy Capt (equivelant RAF rank of Group Captain or Army rank of Colonel), the commander is his CBE award
@@Simon-jj2pu i never understood why he was never promoted higher. I know it was an important achievement to him when he received his full commission. I’ve tried to figure out the promotion system, but I don’t understand.
I would have thought he was articulate, bright enough, hard working an talented, that he should have reached a high level, but I guess he wasn’t a blue blood.
@@peterparsons7141 I have a friend currently serving in the same position, in his late fifties, he denied himself promotion because all he wanted to do was fly and not manage flyers
I swear...this is the 8th time I've seen this already, and it keeps getting better, everytime I see it! Props❤🔥❤🔥❤🔥
Wow, interesting! I see your point.
That two stage mechanical supercharger that RR came up with was one of those ingenious innovations that made the Merlin's high altitude power with simplicity and compact design that used a single driveshaft with two carefully sized impellers that did away with the degree of intercooling problems that plagued the early P38s. It made the perfect match for a pilot friendly P51 that was really the secret of it's success at making green pilots into proficient combat pilots with little distraction. . . . that and it's relatively long legs. Like the A6M it had some very useful reach though it's a mystery why it took the 8th AAF so long to fit drop tanks to P47s. .
Unless he had the strength of a pre puberty girl though Brown did overstate the Jugs compressibilty as any Jug pilot could've and did tell otherwise. It was known for out diving everything and being recoverable at it. The P51 has to go down as one of the great warplanes in any case.
Eric Winkle Brown was one of the best test pilots out. The British used test equipment to test compressibility not judgement by individuals. The Commander of the US Eight Airforce (James Doolittle) asked the Brits to test the Lightning Thunderbolt and Mustang for Compressibility as a lot Lightnings and Thunderbolts were last seen by bomber crews in a high speed dives. Compressibility is where the airflow over the control surfaces is disrupted meaning they do not work, nothing to do with strength. It would be like trying to steer a car on ice, strength was not an issue. You had to slow down to establish correct airflow to pull out, many did not. The Lightning suffered worse than the Jug and did have additional control surfaces eventually fitted, but two boosted unreliable engines and less manoeuvrability meant its removal from the European theatre. The Jug also was also a great ground attack aircraft like the Typhoon. The Mustang with drop tanks had the range the speed the manoeuvrability to be the best escort fighter of the war.
@@anthonywilson4873 I know Brown's version of it but the problem is that his Mach numbers dissent from everyone else's by quite a bit in that his are .71 and everyone else's including other RAF testing range from .78 to .82. The RAF tested the P47D to the equal of 450 mph at 20,000 ft which works out to Mach .826. I don't know why Brown's numbers are that low because the decision by the 8th AAF to go to the Merlin P51 had already been made before Doolittle took charge.
.
Any B17 gunner that had the time to watch for anything but incoming fighters would have about five seconds to watch US fighters disappear at 400 mph. There just aren't any records of P47s crashing into the ground en masse to verify any such claims. What there are reports of is P47s out diving Me109s and Fw190s and none of the opposite happening. Obviously if they had not recovered they wouldn't be writing post battle reports.
.
The 56th Fighter Group rewrote the tactics that Doolittle used to destroy the Luftwaffe at a time when drop tanks were finally used with their P47s and only two fighter groups had been delivered their P51s. They included adopting the Luftwaffe four finger formations in several stacks out ahead of the bombers to break up the Luftwaffe head-on attacks and top cover P47s 4000 ft above to dive on the Luftwaffe fighters and pick them off. So they continued to dive on and away from Luftwaffe fighters well after Brown's tests and Doolittle adopted those tactics for every fighter group in the 8th
.
The P51 was a damned good pilot friendly fighter that could be made quickly and was what the 8th AAF needed. The P47 had hardly been "useless" as Brown put it.
@@anthonywilson4873 ramblings of an old man, James Doolittle begged no one for an answer to Compressibility, the jug had dive flaps, nothing outdove that yet browns mach numbers had german fighters out diving jugs, last place any german fighter jock wanted to find himself was in a dive with a jug, any man that cannot find himself putting the word packard in front of the word merlin i take with a grain of salt
P-38 could be run way overboost because it was a boost house baby. Those superchargers cant be field turnt for 30k+ foot operations with dat thruuuust.
@evanfinch4987 The problems with the P38 stemmed from trying to use the evaporative wing mounted inner-coolers for too long and the compression issue which really was a fatal problem for the P38s high altitude escort role until both issues had been dealt with by the P38L variant. Consequence of the USAAF having bought a fighter upon the crash of it's only prototype.
All these technically advanced turbo second stage supercharged fighters cost lots of money and multiplied x 2 for the P38. And despite the numbers produced were not as conveniently suited for mass production as the simple, pilot friendly and relatively cheap to build P51 or F6F was. I believe the saying goes: "Amateurs talk strategy. Pros talk logistics."
My Dad's 3rd Attack Group, 5th AAF found the Aces loaded P38 groups well appreciated though for escorting treetop parafrag missions against Imperial Japanese Army airfields. Their pilots were well practiced veterans by the time they got their P38s and could boast the 2 leading confirmed scoring US pilots of either theater of the war
In truth, the P-51c models were the most prevalent through the war. The very model flown by the brave men of Tuskegee. It was faster than the D model only just, but carried only 4 guns so it had less weight. Not only that the visibility was lower due to sharing the same body as its earlier A-36 and o.g. P-51 bretheren. The P-47 was also a MAJOR player in the war, often being called "the plane that won the war".
These are great videos, a lot of people put a major emphasis on the P51D models but until later in the war most units just didn't have them yet.
Yes-the 47 and 38 are the ones that slugged it out when the Luftwaffe still had their Aces.
I wish we could see an episode on the planes with camera crew & equipment configuration, it’s resources and maintenance. maybe a bonus, the evolution of it all.
It most certainly is fascinating how the evolution of a disaster happens and Petter explains it as only an experienced and professional can. I love hearing the breakdown and listing of all involved factors and how some of the systems work. For me it does seem mind boggling all the knowledge that the pilots have to maintain and keep on hand all the time whilst at the controls. While not a pilot myself I love aviation and the planes and have since my military days. Shows and docs like this give me a newfound respect and admiration for their knowledge and responsibility. Keep up the good work, Petter. Add me to your fan list!
The US Army Air Force ordered Bell to delete the turbocharger from the P-39 Airacobra; Bell didn't do it on their own. The stupid thing is the original concept for this plane was from a US AAF engineer who specified a turbo-supercharged V-12 engine, but he was removed from the program so couldn't defend the design.

This story almost brings me to tears, it’s so infuriating. To have this man work himself to the point of exhaustion, and breakdown, even against the rejection and snobbery of the very bureaucracy he was trying to help, at the cost or his health and his family- only to have them finally respond by stealing his work and leaving him behind. “Because of the war, you must sacrifice, Mr. Whittle. Not the manufacturers stealing your work. They get quite lucrative contracts. Just you. You get nothing”. If parliament had an ounce of integrity, they’d have levied a small aviation industry tax of some sort to compensate this man and his family. And to add insult to injury- the pilot who invented the jet engine, never got to fly it. And, as if stealing it wasn’t bad enough. They even took his name off of it.
It’s not the jet engine. It’s the Whittle engine The man has at very least earned that.
It's quite sad, his love for aviation and flying makes it worse. His son speaking about him flying at his funeral makes it so much more tragic, that man loved everything he tried to do.

Obra maestra gracias por compartir tan valioso registro..
what a nice way to put it. do well.
While I'm no great historian, to say that Britain lost air supremacy over the UK .... I question... ??
As I understand it, Britain was fighting alone in 1939 and 1940, at the time when the US was very isolationist.
Thankfully, slowly American attitudes changed, and 'Lend Lease' saved the UK until the US was attacked at Pearl Harbour.
Since the start of war, the UK experienced 'The Blitz' and had fought and won the Battle of Britain against Germany with the Hurricane and Spitfire fighter aircraft, powered by the wonderful Rolls Royce Merlin engine.
Packard thankfully built the Merlin engine for the P51 'Mustang' (as apparently named by the British, see 'War Factories Documentary' ) which was a perfect combination.
The 'Mustang' was a major advance in aviation development.
God bless America.

Life is a process. We are a process. The universe is a process.
Little remark: First Whittle''s Jet Engine had radial compressor and turbine and annualar combustion chambers around the engine. Was short but a rather great diameter. Not suitable for installation in a slik nacelle/airframe/wing.
Thanks Admin
You're welcome!
Somebody may have already pointed this out. But those 9 cylinder engines are called Radial engines. Rotary engines were designed by Wankle (think mazda RX series cars of the 70s and 80s) and were not used in airplanes that I am aware.
Wankel engines are a type of rotary engine because the 'rotors' rotate. Rotary fixed crank engines whereby the engine cylinders 'rotate' are rotary engines as well.
This has been covered. Aero rotary engines are not the same as automotive engines. They are two different things.
@@Dronescapes That's not technically true, they are used to power military drones.
A definition from a University paper:
“The rotary aero engine is a special type of air-cooled radial engine, where the cylinders are arranged like the spokes of a wheel and turn around the crankshaft. The propeller is connected to the cylinders, while the crankshaft is fixed to the frame. The rotary aero engine, developed in 1908, set new standards of power and light weight within the aircraft industry. It was adopted by many pioneer aviators and widely used to set records of endurance, speed and height. Many aero engine manufacturers produced different models and variants of this type of engine, which was extensively used until the end of the First World War. The latest evolution of the rotary engine was the counter-rotary arrangement, which was devised and designed by the Siemens-Halske company.”
Those older engines are called radial engines not rotary. I worked on those 40 yrs ago
A ticket on the concorde Paris to New York was around 10k $ in 2000.
There were many ways to get them much cheaper, as low as $3,500 round trip Paris/N.Y. It was higher than today's (cheapest) Business, but much cheaper than 1st class, and the level of service was astronomical from the moment you arrived at the airport, to the moment you landed in N.Y. including a dedicated hub for immigration. the seats were small, and not comparable first class, but the trip was so exciting from the first minute, that the handful of hours passed as it was a one hour flight. It not only shrunk flight time, but most importantly, it shrunk the perception of flight time. I guess that perhaps over time that perception expanded again, but it was like going to watch a great movie that you hope does not end.
Amazing
31:22: Mustang an excellent ground attack plane? Are you sure because due to its lack of a sturdy frame like the Thunderbolt, it suffered great losses in that role from ground fire!!
Can you please make a video on the history and engines of Pratt and Whitney
My Dad designed Compressor components for many different engines at General Electric for both Military and Commercial Jet Engines. I know that he talked to Pilots about the Performance of General Electric Engines. There was an Aircraft in the 1970's that originally had Pratt and Whitney Engines and were retrofitted with General Electric's Jet Engines and the Pilots told my Dad verbatim "We can fly the Plane and not the Engine now!". I might add, that my Uncle's Specialty was designing Jet Engine Components for Turbines at General Electric. One word that stands out in my mind; Thrust
I can only think it was the F-14 Tomcat. Politics play important in military aquisation, most people don't realize it. Pratt put the TF30 in the A model Tomcat. As the weight increased during it's developement, PWA knew the older TF30 was not the ideal dog fight engine. In the F-111, (fighter bomber without all the throttle banging of a dog fight aircraft), the motor performed well but was prone to compressor stalls. Thus Pratt had another newer, more powerful engine in developement to put in the Tomcat. But when the B version Tomcat came around the contract was given to G.E. This engine (I believe) was a derivative of the F-110 flying in the "Bone". A more modern good engine that finally made the F-14 fly w/out regard to AOA ans other flight parameters. I did witnessed an emergency landing of a G.E. powered Tomcat when one engine stuck in afterburner and had to be shut down. As a pilot, I can tell you 'shit happens' no matter who makes the motor!!!
Originally G.E. And Pratt and Whitney’s turbojets were British, thanks to Sir Frank Whittle’s invention.
The Americans (thankfully) recognized his genius much more than his countrymen ever did.
His was really an invention troubled by every possible obstacle thrown his way.
We own it to the Wright brotthers (RIP) honestly.
The merlin and every 12 cyl engine like the merlin was not an inline engine, they were V configuration engines with a 60 degree offset from each bank of cylinders
Thank you for pointing this out. It really makes it hard to legitimize this content with such a blatant mistake throughout the entire video.
I thought the same thing, and was wrong, like you. An aero inline can be from several different configurations. Basically, if cylinders are in line, it's an inline aero engine. A V configured engine is an inline, but, an inline isn't necessarily a V engine.
Thanks!
Thank you!

Were those people 30m from the airline landing strip xD. The good old days, now they make a fuss even if a small bird flies in the landing and takeoff area.
Well, maybe the safety of air travel is also a good thing these days.
Nice video.
Some questions while I am watching it.
How is the rotary engine supplied with fuel if all cylinders are rotating in high speed?
If the in-line engines are more powerful, why the WW2 bombers were equipped with radial ones. FW-190, La-5 too?
what doesn't get mentioned when it comes to these engines is the compression ratio and the higher compression ratio of allied planes is the high octane fuel we could produce and the germans couldn't.
Those German turbojet had a litany of issues, so many that the Soviets, after the war, ditched them in favor of Whittle’s engines for their MiG15. They were over engineered, flame-out issues, materials, fuels, etc. You have to wonder why three different German companies (Heinkel, Junkers and BMW) spent years and precious resources after the first flight in 1938, trying to develop an engine that by the end of 1944, when the Me 262 became operational, was still utterly flawed.
It is certainly not something to write home about.
It is interesting to note that Heinkel, and Von Ohain eventually tried to outright copy Whittle’s engine, but that attempt also went nowhere.
You can safely say that if Whittle had 1/4th of the support that Von Ohain, or the German industry had in 1929, when his project was rejected and delayed by at least 5 long years, Britain would have had a working turbojet before the beginning of the war, wiping out any German ambition.
They would have also secreted Whittle’s work, so Von Ohain would have had to work more with his own brain, rather than being able to compare notes.
Von Ohain had a comfortable access to Whittle’s work by his own admission at the beginning of his quest to build a turbojet, when Whittle finally restarted working on his own engine with the few money he could privately raise, which was a drop in the bucket compared to what Von Ohain’s could later spend. As he put it: “I had all money I needed”.
I feel Germany’s turbojet was over hyped (Nazis mastered propaganda well), and obviously Whittle was under appreciated, or completely ignored, and even ridiculed.
The bottom line is that both “proper” axial, and centrifugal turbojets were not German at all.
Germans had a clunky propaganda turbojet that was quite useless.
@@Dronescapessadly you are wrong on every point you try to make, even though you’ve just watched the General Electric film for goodness sake. Their engines you have just watched owe their very existence to the German axial flow Junkers engines which became the standard jet engine built by every advanced nation to the present day right up to the present day. The Whittle type centrifugal type jet died out very quickly and became obsolete.
Indeed, we didn’t supply 100/150 high octane fuel, it was supplied by the Americans secretly to us luckily just in time for the Battle of Britain. I say secretly as they were still neutral. This gave the Spitfire a speed a speed matching the 109 luckily.
@@Dronescapesabsolute romantic nonsense. Capt Eric Brown responsible for evaluation of German jets at RAE Farnborough, has said many times on film that the ME 262 ‘…was without a shadow of doubt, the most formidable fighter of WW2…’ He also flew many other German jets, the He162 Volksjäger he said, ‘would have run rings around the Meteor had it had the misfortune to meet it in combat.’
Thw apollo was a really pretty plane
War thunder does a great job of modeling these planes
Regarding Whittle, imagine that, the government steps in, takes something from a citizen (a revolutionary design), and then gives it to one of their buddies (Rover and RR). I’m sure no one in the government got paid huge kickbacks by Rover and Rolls Royce. I just hope Whittle was successful enough to never want for anything. Because he SHOULD have created a multi-billion dollar company given what he had. But, as usual, the government used fear and “the greater good” as excused to take what they wanted.
Edit: I wasn’t even through the story. They even took over his company. Absolutely disgusting. Just remember Frank Whittle the next time you vote for someone that starts talking about protecting you or providing for you. If you give them that kind of power, they WILL use it, perhaps against you.
1935 Whittle gave up his patent on the gas turbine
A patent was submitted by Maxime Guillaume in 1921 for a similar invention which was technically unfeasible at the time. Whittle's jet engines were developed some years earlier than those of Germany's Hans von Ohain, who designed the first-to-fly (but never operational) turbojet engine.
Correct, in essence the first working turbojet was created by Whittle. His engine (and variants) also became the first U.S. turbojet to fly (Bell XP-59), and the first U.S. operation one as well (Lockheed P-80).
It also powered the first operational Soviet jet (MiG-15), after Russia ditched all variants of German engines as flawed, dangerous and utterly unreliable, and they ended up cloning Whittle’s engine (RR Nene), after purchasing a handful of units.
Interestingly the first German flight was not powered by an axial turbojet, but by none other than a centrifugal one (Whittle’s invention), and today we know that Von Ohain had access to Whittle’s work, as it had been copied and distributed in Universities across Germany in the mid 30s, when the young German engineer started working on his engine.
Considering that Whittle had been ostracized, delayed, and unsupported for 6 years, that is a remarkable achievement. His milestone engine was ultimately achieved with very limited private funds, £200,000 in today’s money, practically nothing for such a feat. In Germany Von Ohain had been fully supported and pampered by Heinkel, a very different treatment.
The secret kept during the war was that the P-51 was led in design by North American’s German-born engineer…Edgar Schmued.
Indeed
31:16 what are they shooting here? Houses?
Amazing documentary thank you, frank whittle has a very interesting story. What an Incredible guy he was. 💚
Our pleasure!
For the first aircraft flight propelled, would it be the 14 bis? That near Paris, the 14-bis made a manned powered flight that was the first to be publicly witnessed by a crowd and also filmed. It was also the first powered flight by a non-Wright Brothers airplane.
The P-38 Lightning you mentioned lacked the maneuverability of single engine fighters? That must be why the Germans called it the fork tailed devil and had so many air to air kills it was impressive. Faster and more maneuverable that the bf-109-g6. That’s impressive if ya ask me for a twin engined fighter-bomber.
Obviously fotgot the corsair and the hellcat, the corsair was the only U.S. WWII fighter to remain in production after the war
The Mustang with the Allison engine would have been a fiasco. I wonder why they never made a test with a P38 with RR Packard engines. Probably it would have been a rocket? If I am wrong then apologies.
You make a good point.
I think the P-38 got the superior powered Allisons as it had the room for the extra kit which single engine fighters didn't without screwing up aerodynamics, so they weren't needed. Was similar to the Mosquito performance wise, which had different RR engines to the Packard model for the P-51.
The Hornet was just about the top twin piston engine fighter evolution, basically an OP single seat Mosquito, but the war ended before it saw combat.
The Fw190 prototype was powered by the BMW 139 .
All the comments about a Merlin not being an inline engine are wrong. ( I thought the same, too.) Turns out an inline aero engine is any engine where the cylinders are in line. There's a lot on the subject, not just wikipedia.
Have you done my Dad's ship HMS IMPLACABLE R86
If two fighters have a slight difference in speed ,wouldn't it depend on how good the fighter pilot was fighting the plane?
It seemed a shame to me that just after hostilities Packard was faced with punitive new licensing fees and had to cease production. A chap I knew praised the Packards and their precious toolkits; all the parts were painted unlike the RR ones which had bare brass and copper.
Good documentary with a lot of valuable information. A few issues:
1. You are unfair to Ford. He certainly had issues, but you do not present them accurately. His resistance to British contracts was before Pearl Harbor. This idea that he only wanted to build 'defensive' arms is nonsense. He was an isolationist. After Pearl Harbor, Ford was all in. I suggest you look at what came out of Willow Run, B-24 Liberators in incredible numbers. And the B-24 is about as offensive as you can get.
2. The P-47 with drop tanks could also fly escort missions to Berlin.
3. The P-51 range issue in the Pacific was solved at a terrible cost by Iwo Jima. P-51 squadrons based there could escort the Superforts to Japan.
4. You should have addressed the issue of the varied performance of the RR and Packard Merlins.
5. The Doira hardly solved the Luftwaffe problem. By this stage of the War, Luftwaffe pilots were entering service with minimal training, in part because the strategic bombing campaign was destroying the synfuel plants and there was no way to train them.
The Concorde would've been the perfect... Air Force 1.
This whole story is so confusing that I still don't understand what happened!! An officer took command of a modern Russian ship, and there was complete confusion?? And the sailor who saved the day not only wasn't rewarded but kicked out of the navy without a pension?? The entire crew should have defected and delivered it to the west,where they would have been rewarded to the point where they would have never had to work again for the rest of their lives and lived in high style!!
The commentor refferd to the radial engine wrongly as rotary engine. These are two different types of engine-layouts.
There is an answer for that, and it is covered in other comments prior to this one.
Why not mention of the F4U
Shame the P51 wasn't as beautiful as the Supermarine Mk9 Spitfire
The ultimate fighting machine of WW2 was the Me-262
The airframe was excellent, but the engine was a complete disaster, so much so that after the war, except for a short-lived attempt made by the Soviets, they eventually switched to the reliable RR/Nene/Whittle British reverse-engineered turbojets for their amazing MiG 15.
The Czech Air Force also made some rather useless attempts but eventually switched to the British engines as well...
The French also tried to develop them together with Nazi engineers, but that was a no-go either.
Nobody cared for those over-engineered, short-lived, fragile German engines.
Despite 6 long years of development, massive investments, and many German companies such as BMW, Heinkel, and Junkers, they still barely worked. You can also add to that the fact that they had the lethal tendency to flame out on the pilot.
Toward the end of the war, Heinkel and Von Ohain, realizing that they wasted all that time to develop a 'lemon', eventually tried to outright copy Whittle's engine, which had been an inspiration for Von Ohain right from the start, as he had access to the British genius' work all along.
Eventually, axial turbojets, as predicted by Whittle long before Von Ohain even started working on his engine, surpassed the centrifugal turbojets, but they were definitively not based on those utterly flawed German engines, as the Brits had been working on both solutions for a long time (and those both worked quite well).
It is still a classic example of over-hyped German wonder-weapon, when in reality the Me 262 was utterly useless.
A wonderful airframe with a tragic engine made it inconsequential.
True but most modern jets are using axial flow engines except turboprops and APU-s are of Whittle's design
True, but proper axial turbojets(mid 50s) were anything but German derived.
Perhaps you are not aware that Whittle purposely discarded the axial compressor precisely for the reasons that plagued the German engines.
He realized that it would take too long to develop an axial turbojet, so he sought an intermidiate solution that was dismissed by his sole examiner, none other than Griffith, the author of a seminal paper on axial,compressors in 1926, almost a decade before Von Ohain started working on his project, fully funded (the opposite of Whittle) by his patron, Mr. Heinkel.
You can say that Whittle had the perfect short term solution, but was halted by a person that was working on an axial solution, whereas Von Ohain who had full access to Whittle’s work, and presumably to Griffith’s paper from 1926, simply made the wrong choice.
Heinkel and Von Ohain would eventually also try to mimic Whittle’s engine, but it was too little, too late.
Companies like Metrovick had been working on (proper) axial solutions all along, in tandem with Whittle’s solution, which had been delayed by bureaucracy, Griffith, lack of funding, and support by at least 5 long years (1929 to 1934).
When you look at it objectively, and consider the resources that Germany poured into developing a flawed turbojet, you can easily compare it to David VS. Goliath.
Still, a broken, and humiliated Whittle managed to beat the might of Germany’s effort to the finish line, having produced a working turbojet in April 1937 (of course he could not afford an aircraft to test it, as Von Ohain could).
Whittle’s engine powered many aircraft, including the first jet aircraft to fly on U.S. soil, the first operational U.S. jet fighter, the first commercial jet, the formidable MiG15, and many others.
When it was surpassed, as predicted by Whittle, it was almost 1960, 30 years after he presented his (rejected) projet to the British Air Ministry.
He was a true genius, and I cannot say the same about his counterpart(s) who piled up strategic and engineering mistakes.
That child at the end was put in the system. That child's life is now over.
I too was a child of the system. It almost killed me, several times.

A question for the crowd, were two stroke cycle engines ever investigated as an option?
They've been used, but oil consumption is a serious problem in high power engines
Why do all the engines sound like the Wright 4-cyl???
Narrator keeps calling V8 and V12 engines, inline engines. This is a major gaffe on par with calling an inline engine, a V style or radial. Otherwise, a good video and informative.
3 or 4 hours did come to pass.
😮😮😮
Excellent
Is the voice around 1:52:00 AI generated??
Absolutely not. When the video was made even having a synthetic voice of a computer was a luxury, and AI was not even a thing…
It seems that we are collectively becoming more, and more obsessed about AI, including the inability to distinguish things.
I can only imagine what it will be in a couple of years, when people will doubt and dispute everything they hear and see.
Perhaps this will be the true disaster created by AI, more than people losing 100s of millions of jobs.
Human confidence will slowly plummet, overwhelmed by constant doubts.
Politicians and regulators are also so far behind in curbing it that, when you add the inability of people to distinguish, or to be willing to do a simple research, it can only lead to complete chaos, as AI slowly, but surely, infiltrates our daily life

... ME109, not a BF109
They are the same thing
