My dad was a Hungarian who immigrated here after during 1956 Revolution and got a job at a machine shop that made some of the parts for The Arrow. Years later my Dad along with all the others who worked on it there were gifted a copy of "Avro Arrow: The Story of the Avro Arrow from Its Evolution to Its Extinction" I still have it and treasure it to this day.
⁷⁸😮😮
The CF-105 Avro Arrow was the:
1) First a/c designed with digital computers being used for both aerodynamic analysis and designing the structural matrix (and a whole lot more). * ( The claim that it was the first aircraft designed/tested using the IBM 704 cannot conclusively made. It is known that the unit at AVRoe was the only 704 sold in Canada.)
2) First a/c design to have major components machined by CNC (computer numeric control); i.e., from electronic data that controlled the machine.
3) First a/c to be developed using an early form of “computational fluid dynamics” with an integrated “lifting body” type of theory rather than the typical (and obsolete) “blade element” theory.
4) First a/c to have marginal stability designed into the pitch axis for better maneuverability, speed and altitude performance.
5) First a/c to have negative stability designed into the yaw axis to save weight and cut drag, also boosting performance.
6) First a/c to fly on an electronic signal from the stick and pedals. i.e., first fly-by-wire a/c.
7) First a/c to fly with fly by wire AND artificial feedback (feel). Not even the first F-16’s had this.
8) First a/c designed to be data-link flyable from the ground.
9) First a/c designed with integrated navigation, weapons release, automatic search and track radar, datalink inputs, home-on-jamming, infrared detection, electronic countermeasures and counter-countermeasures operating through a DIGITAL brain. * (We are researching some of these claims. Stay tuned for an update.)
10) First high wing jet fighter that made the entire upper surface a lifting body. The F-15, F-22, Su-27 etc., MiG-29, MiG 25 and others certainly used that idea.
11) First sophisticated bleed-bypass system for both intake AND engine/exhaust. Everybody uses that now.
12) First by-pass engine design. (all current fighters have by-pass engines).
13) First combination of the last two points with an “ejector” nozzle that used the bypass air to create thrust at the exhaust nozzle while also improving intake flow. The F-106 didn’t even have a nozzle, just a pipe.
14) Use of Titanium for significant portions of the aircraft structure and engine.
15) Use of metal composites (not the first, but they made thoughtful use of them and were researching and engineering new ones).
16) Use of a drooped leading edge and aerodynamic “twist” on the wing.
17) Use of engines at the rear to allow both a lighter structure and significant payload at the centre of gravity. Everybody copied that.
18) Use of a LONG internal weapons bay to allow carriage of specialized, long-range standoff and cruise missiles. (not copied yet really)
19) Integration of ground-mapping radar and the radar altimeter plus flight control system to allow an interceptor/reconnaissance role. The first to propose an aircraft be equally adept at those roles while being THE air-superiority fighter at the same time. (Few have even tried to copy that, although the F-15E is an interesting exception.)
20) First missile-armed a/c to have a combat weight thrust to weight ratio approaching 1 to 1. Few have been able to copy that.
21) First flying 4,000 psi hydraulic system to allow lighter and smaller components.
22) First oxygen-injection re-light system.
23) First engine to have only two main bearing assemblies on a two-shaft design.
24) First to use a variable stator on a two-shaft engine.
25) First use of a trans-sonic first compressor stage on a turbojet engine.
26) First “hot-streak” type of afterburner ignition.
27) First engine to use only 10 compressor sections in a two-shaft design. (The competition was using 17!!)
Good to learn about Canada's contribution to aviation innovation!
I mentioned above, they were huge in the USA for space but never get mentioned.
Canada has always had one Achilles heel.......the bloviating nabobs of OTTAWA
CANADA LIKE MOST COUNTRIES HAVE THE PROBLEMS OF CORRUPTION CONTROLLING THEM. CANADIANS ARE TOO DUMBED DOWN TO REALIZE THIS!
Nothing has changed, as of July 2024. Why the hell, are we buying a "strike fighter" to defend North American airspace, and arctic sovereignty ?
The Orenda Iroquois engines were also an in-house design which Avro was looking to sell to France, who I believe had expressed interest in using them in the Mirage fighter.
That wasn't likely to happen without Arrow, or some other aircraft using the Iroquois. France wasn't going to take over the development costs of someone else's turbojet.
I wish more of these videos would talk about WHY these engines would have been the most revolutionary engines to date.
@@number1trucker They did have an excellent thrust-to-weight ratio for its time.
@@winternow2242 Why do you think anyone had to take over Iroquois costs, the engines where ready for the 206
@@pwc7475 Because they needed engines for more than just 206. Canada needed to develop the engine for mass production, and that never happened. Odd that, nearly a year after it was flown on a B-47, the Iroquois was never used to fly an Arrow.
Such a beauty design.
As a Canadian I'm not crying about this but I say you packed a lot of info into this. I did not know about SAGE. Interesting video.
I'm an American, but I've always been a fan of Canada - always will be. The Arrow was an awesome (and beautiful) aircraft that could have outperformed the US F-102 and F-106 .... if it were built in numbers, it would have really "stuck it" to the Soviet Union, and made them do a re-think of their over-the-pole bomber doctrine against North America.
I would say, quite comperable to the F-106. Maybe better range and payload though.
And probably 100mph faster. Being that the F-106 was no slouch either.
My Highschool in Moosonee was the part of the old Pine tree line.
Considering that the F4 PHANTOM program was started in 1955 the CF 105 was hardly the only mach 2 fighter in development at the time
The mach 2 variant was merely an underpowered prototype. The new variant, that had just been completed and had a scheduled test flight the week after the program's sabotage, was ready to challenge mach 3.
@@EdmontonRailsthere was virtually no chance of mach 3, and very little of going much faster than that "underpowered" airplane that couldn't break mach 2. The j75 powered Arrow, on internal fuelz had virtually the same thrust-weight ratio as an F-106, which achieved speeds well above mach 2. The improvements in thrust-weight ratio wouldn't have been that significant, from .67 to .74, about the same difference between the F-5E and the F-104G. Arrow also had a higher thrust-weight ratio than XB-70A, SR-71, MiG-25 and Mirage 3, all of which were significantly faster than Arrow. Aerodynamics obviously had more to do with Arrow's speed than its engine, which incidentally had no problem taking the F-106, F-105 and the Super Crusader well past mach 2. Had Arrow 2 gotten its Orenda engines, it would have had a lighter empty weight than Arrow 1, by about 4 thousand pounds. However, Arrow 2 was going to carry about 400 imp. Gal more fuel, which translate to another 3200 lbs in fuel, and that's before adding the MA1 weapons system (about 2500 lbs) and 8 Falcon missiles (nearly half a ton), meaning that that mach 3 airplane would have had virtually the same thrust-weight ratio as the plane that couldn't break mach 2 in a dive. Arrow wasn't sabotaged. It was cancelled by a government that couldn't afford it.
fun fact, look at the air intakes of the phantom and the arrow...... you will be pleasantly surprised.
@@alecrichard9395 what fact is that?
@@winternow2242 Splitter vane intakes, with variable ramps. Keeps the airflow subsonic for the engines to ingest, despite supersonic speeds. I think it was realistic to assume that the CF-105 would have achieved Mach 2.5, or better.
A little or maybe a lot faster than the F-106 F-104, or F-4.
CANZUK should coordinate the design, development and production of all its military equipment.
@seanprice7645😂
The fastest ww2 era plane was not the P-47 thunderbolt, it was actually the German rocket powered Komet which was over 700mph. There were several faster aircraft than the P-47, notably the P-51 mustang reached 440mph and of course the ME 262 was 560mph. All of these were WW2 aircraft.
Propeller driven a/c.
@@RPMZ11yeah...... P-51 is a propeller driven aircraft
@@HeavyMetal82
OK....and?
@@RPMZ11 and your point?
Not a bad video, but I don't remember you mentioning the titanium construction.
Canook???? lol
A lot of Canadians were making this more then it was. It was a good plane but the country could not afford to keep it going for its size. Fortunately Canadas loss in Engineering was a huge gain for the newly formed NASA space program where 25+ Canadian engineers were converted to American asap to develop their Apollo program, Gemini program and other space craft designs, some went to Boeing, and some went to England to help out with the Concorde.
Canada lost thousands of its most intelligent, capable of talented citizens following the sabotage of the Arrow program. The average IQ of Canada dropped that year.
Here's the rub of the situation, that usually get down played a lot. The design phase of the Arrow was well over 5 years, way to long, by the time they got to testing the prototypes, both the USSR and the USA had moved on to ICBMs delivering most of the nuclear warheads to target. Literally, the technology had been bypassed, and most of it due to a design phase that took to long.
This is luftwaffle
The USA has got a lot to answer for.
Like what?
@@winternow2242 e.g. Look up the Lockheed bribery scandals.
Right. That point of view will dead end quickly.
@@nizm0manlooked up. Also know that American aircraft have served Canada well for years. As for Lockheed bribery scandals, they're irrelevant to Arrow.
Nothing's changed. The US killed Bombardier's C-series too.
Unfortunately , they were on the way to becoming obsolete very quickly.
Oh, is that why many of its features and design innovations ended up on US aircraft in later years ?
@@skxj Dream on.
@@dukeford8893No dreaming here, it's a fact look into it.
Canada was ahead of the US in titanium manufacturing. When the Arrow was cancelled Lockheed Martin bought the machines and hired the guys to run em in the US. All the titanium sheets were bought and sent down for the SR71. Fly by wire was invented in Canada and used on the Arrow first. the Arrow was designed with a concealed missle bay long before it was seen on the f35 and f22. Why ya think all the Arrows engineers were hired up by NASA, Lockheed Martin etc. When the Arrow was cancelled ?
@@skxj Fly-by-wire was developed by the Germans, not Canada. The F-106 flew three years before the Arrow, and had an internal weapons bay (it was also faster and had better range). Lockheed developed new titanium manufacturing techniques for the SR-71; if the Canadians had something to do with that, I've never heard of it. Provide some proof.
@@dukeford here is a few firsts in aviation ,
6) First a/c to fly on an electronic signal from the stick and pedals. i.e., first fly-by-wire a/c.
7) First a/c to fly with fly by wire AND artificial feedback (feel). Not even the first F-16’s had this.
8) First a/c designed to be data-link flyable from the ground.
This jet did not get its fair chance, first jet to be made of Titanium which we used in our SR 71 Black Bird, this jet would have hit Mach 2.5 with those new engines or more, the whole thing was sabotaged, 70 thousand feet ceiling, when I really studied and watched different docs on this jet, the US was going to invest , so were the French and then all of a sudden nobody wanted it, then when they herd they were being destroyed, the phone rang and every Country wanted it ? My US Government , the French and even the Brits did not want Canada to have this jet, it would have sliced into their pie, and a small Country should not have a jet better then the big 5 Countries in the air plane business. Just my opinion as a US citizen now living in Canada I understand now how Canadians really hurt over this even to this day. And to say this jet had no impact is ridiculous, the Canadians are very innovated and that jet looks like so many that came after the Arrow, even the Concorde looks like it.The Canadians came close to getting to the moon with this thing, a launch off the Arrows back was in the planning. History may have been different.
The Arrow was a decent airplane with some interesting features, but "the best"? Not even close.
Greatest jet that never achieved anything, nobody wanted, it remained a prototype. Today its a fairytale.
Unproven Orenda engines, plane with a few (single digit) flights, vs existing Mach 2 interceptors with better range. Not quite the best in the world, and not fully developed. If's do not amount to are.
A good plane. But it was not by any means the best at the time.
Mig 21 was better.
Would putting the engines on the top of the wings make this more stealthier? Similar to the Saab A36 supersonic bomber design.
