Jet Engine Thrust Test - Fuel Experiment (Jet-A vs Diesel vs BioDiesel vs HydroDiesel)
Vložit
- čas přidán 27. 06. 2024
- I test run four different fuels in my RC jet engine to see which one makes the most power. Jet A, Diesel, BioDiesel and HydroDiesel which contains 80% Diesel and 20% water.
I first build a jet dynamometer then I put all four fuels to the test with some intense full-throttle runs, the results are very surprising.
The test I run on each fuel is 2 straight 20-second Dyno pulls, this is much much longer than anybody would hold the throttle in the full power position under any use except for maybe a fighter jet..lol.

As an engineer (BSEE) I enjoyed not only the experiment with different fuels, but the science and the mechanics behind constructing that engine. Well done!
what kind of engineer? have you looked into metamaterials and how they can interact with gravity waves?

@@user-ob6vn2cs9r I assume so if you get a chassis light enough. A better question is whether it's legal or not.
Ok...I'm an aviation mechanic and a CJ-3 pilot. I have to say this blew me away. Almost all turbine engines are certified for different fuels including gasoline for a limited amount of time. I've run 100LL in pratt engines with zero problems (limited to 150 hours with pure gas). The Williams Air Research engine on the CJ are NOT certified for operation with gasoline. This test shocked me. It must be a viscosity issue. Jet A produced the most inter turbine temp and highest RPM as well as the most thrust. Williams engines don't have nozzles or injectors, they have a "slinger" and are operated by FADEC (full authority digital engine control). I don't think you could have put on a more pertinent test. It literally changed my mind about several things. Thank you very very much!!! By the way, lubrication from the fuel has no particular benefit for the engine. The only place it could make any difference is the fuel controller itself. Prist is an additive that keeps the fuel from freezing and will prevent microbials from growing. But it is corrosive and has to be used sparingly. Most engines are restricted to .015% or 1.5 gallons in 1000 gallons of fuel. If your fuel isn't heated by bleed air or other you WILL be using prist or your fuel will gel and may flame out....ask a guy that has experienced...oh...that's right...it was ME! 29,000' in a Pilatus PC-12 the fuelers didn't add prist. It didn't fully flame out but it DID become a glider real quick! I had to dead stick into DAL from FL290. DID find out how well a PC-12 glides! hehe
As an helicopter mechanic for 23 years, I can tell you this test went exactly as I thought it would. Each of the fuels has its own specific gravity, and unless the metering jets are adjusted to compensate for this you'll get weaker power due to incomplete fuel burn. The reason that the hydro diesel did better than the other two is due to physics. The water in the fuel cools the air as it is injected, this increases the aircharge in the combustion section much like nitrous does in a car. Older turbojet engines actually used a water injection on take-off(though it was injected into the compressor section not the combustion section) to increase the performance of the engine. The AV-8B Harrier still uses this today, to boost engine power when in a hover. Jet-A is a very dry fuel, and is anhydrous, and soaks up water like a sponge. This is the reason why a lot of airplanes will put an additive known as colloquially as Prist, though many manufactures make it now, that lowers the freezing point of the water suspended in the fuel to prevent ice build up on the fuel filter screens. So, that pretty much means, hydro-fuel will more than likely not be coming to an airline near you any time soon.
Great explanation.
Wow
Germans used water methanol injection to ad more boost without the fuel igniting from pressure. It allso cooled the pistons. Would be nice to see if it worked on a jet. Alcohol prevents the water from freezing allso tho they propably have tried it in jet engines minding the hydro diesel. In carage it could work coz you don't have to be worried about icing.
@@ark-mark1 If you google it you'll learn that it has been used in jets many times.
the USAF and McDonnell Douglas experimented with F-4 engines with water injection too, during the Israeli-Arab war to counter the Egyptian MIG-25, they decided to not give the result to the Israelis though because it is considered too advanced
Jet engines are a masterpiece of engineers work.
Being a commercial jet engine mechanic, i fully support this message!
It was so Expensive
Wait till you look into rocket engines...mind blown
And you can thank the…. The uh.. it’s not important who invented it…
@@Grombrindal91 Being a privately funded rocket scientist associate, I fully support this message.
That was extremely interesting, as I knew a jet engine can run on almost any kind of fuel, but I didn't know how effective alternative fuels are. Awesome stuff.
How then does the white sort of smoke comes out of the jet engine in the sky, what kind of fuel do they use??
@@democracyforallContrails (the white lines) form when the warm moist exhaust fumes from an aircraft mixes with the cold ambient air producing ice crystal clouds.
You Sir are an absolute genius!! I cannot believe the engineering skill and knowledge on display in these videos..I've never seen anything so brilliant!
Absolutely amazing testing! A+++ dyno build and really enjoyed the RC jet engine testing!! Looking forward to your next episode! I'm planning to test the lubricity of the 4 fuels soon.
I'm calling it now, biodiesel has the best lubrication, Diesel second, hydrodiesel third, and jet-a last.
Look fwd to that!
@@Taydrum i agree that i think jet fuel is last, but i'm unsure about the various diesels. i would put hydrodiesel higher.
Can I subscribe 5 times?
Just builds a jet engine dyno when he needs one.....
I fkn love this channel.
This dude does the most fascinating stuff that I only dream about doing, but just as I say “but what about....” he’s done it and shows you.
If he was my science teacher I would have been having lunch with him.

LoL HAHAHAHAHAHAHAHA😂
Hhhhhhh
😀😀
Right 👍
After 81 years on this earth I,m rejuvenated. Brilliant engineering. John from Oz
This was just spell bounding, I had a very hard time taking my eyes off the screen for even a moment. Amazing!
I dont know why but I am so in love with jet engines. This spooling, this massive amount of power...just amazing!
Man you bastard🤣🤣🤣! I'm supposed to be working right now, but this is too exciting not to watch... immediately. Hiding in the broom closet at work watching with headphones.
That thrust dyno is fucking rad bro!
Haha! ❤️ Thanks I really appreciate it! I'm mostly tried out the hydro diesel because my RC guys are looking for a cheaper fuel than kerosene.
@@WarpedPerception Looks like a great solution. It seemed to work just fine and at 20% water I'm sure it's 20% cheaper lol
@@WarpedPerception You can buy k1 cheaply at some gas stations. They make you fill out some forms to get it tax-free for home heating.
@@brsrc759 so the hydro diesel is about $1.80 a gallon, versus like $3.20 a gallon for kerosene here in Illinois. I had a hard time editing this video for multiple reasons but I forgot to put a part in there where I talk about fuel mapping in the ECU for the jet, I believe that if you can remap the ECU slightly to allow you to get 10% more hydro diesel through that injector it would make as much as jet fuel at a cheaper price. The one thing about the hydro diesel that I like is that it burns very clean, it doesn't have that kerosene smell.
@@WarpedPerception that's crazy cool!
Absolutely amazing channel. Can't say enough about the work you do.
GREAT video, from the photography, testing methodology, and all the other stuff that goes into it.
Idle is 35,000 rpm. The precision engineering these parts must require is unreal.
Indeed. And remember this is a larger one. A t35 kolibri for example idles at 80k rpm or so and maxes out at 260k.
What rpm mean? Is speed or pressure
@@Christian.987 revolutions per minute.
@@Christian.987 it’s how fast the turbine spins. To put into perspective, a car RPM at idle around 1000 to 2000, this jet engine is around 35000
Can I strap 4 of these engines to my arms like a jet pack if so where can I purchase?
The jet engine: Starts to sound loud
The subtitles: [Music]
ah yes, music to my ears
For avgeeks, yes!
Exactly
The subtitle changes into "Put on your ear muffs, it's gonna get better... well, insane!!" xD
Her: so what kind of music do you like?
me: It's complicated
Excellent build and interesting results at the end.
Lemme give you my summary of Fuel Experiment:
picture - 100
sound and music - 100
topic - 100
conciseness - 100
Overwhelming!
Wow... what a marvel of engineering. I'm imagining the forces everything must be under and it's just mindblowing. And to think this is so tiny compared to one from a plane! Truly appreciate this video!
I couldnt agree more
What is this engine for?
@@francocastilloARrc planes would be the main application but people have been slapping those on pretty much anything
That was ridiculously interesting. Appreciate all the effort you made with this, especially in capturing the sound.
Awesome! I was surprised that the Hydro-Diesel did so well !
Amazing video and very surprising results. You've done amassing job creating this video, really enjoyed it.
That is so amazing and cool. Nice and simple jig to measure the thrust. Must be some very tight tolerances built into that tiny giant. Thanks very much for the video.
One of the coolest experiments I've ever seen. Huge fan (no pin intended) of turbofan and jet engines since I heard one. Long time ago. Subscribed.
Watching you build is often creates mega envy. You have a disturbing amount of AWESOME TOOLS available for use! Serious industrial grade mojo! 😂
The sound is amazing. Thanks for this perfect video.
Lol, the close captions say "Music" when the turbine is accelerating. Yes, youtube, indeed, lol
Very nice. the reaction of the engine to the different fuels was fascinating. The amount of flames and smoke after throttling down especially. As a driver of ultra-low-sulfur diesel vehicles I know that they have extra lubrication additives to counter the lack of sulfur.
Thank you for the hard work creating great content!!!
Your production is insane! Much respect bro!
Some people are asking me where to get the HydroDiesel here's where I got it $1.80 a Gallon, Trillion, LLC, John Leonard Email: jleonard@trillion.energy
Any plans for kerosene in the future on this test? Excellent video by the way!!
@@masterpanther1 i think jet a and kerosene are basically the same think.
Yeah quite possibly. I was just wondering if I had already missed it or something. But I would like to see results if used in this test.
that hydro diesel reminds me of the old J57 water burners. I bet with that jet A if you added the right amount of water you would see a increase.
i'd thank you for the Noise warning, but you reduced the volume of that part so much that its basically perfect, didnt have to change volume at all
And you sir deserve to be on national TV every evening and morning episodes. Give us more!!
That was FREAKING AWESOME MAN! I love this type of stuff man! Thank you for that brother!👍🏾😎
06:10 is just glorious to watch that engine roar
my PS4 does that too!
Watch this man's simple trick to make flying a jet fighter less expensive! Navy mechanics hate him!
These lil engines are so friggin cool. Also some of the closed captions are hilarious while the engine is powering up or down.
Great video. As a 45 year A and P. It was interesting to see the different fuels. As a side note the best was to pour out of a 5 gallon drum is lay it on a bench with the bung on top, then slowly roll it. It is then easy to control the flow..
The gigantic flask is back!

"IN THRUST WE TRUST!" :-) Great job on the video & the JET ENGINE THRUST stand. Thank you for sharing. I work on jet engines & aircraft as an A&P mechanic BTW.
KSP
Awesome.
This is exactly what i needed. As a senior student in Uni, this is my project topic, Alternative fuels especially Bio-fuels. thanks a bunch bro, this gave me an headstart....
Your welcome
Brother! I love the jets you build, and the related experiments you demonstrate, such as this one... for example, I also loved the 'see-through' jet project that you recorded on one of your other vids.! Thank you for the great vids you make and share with us! 😃👍
That is one impressive set-up and test ! Thanks for taking the time and effort to do this.
Just a quick tip related to your waterjet: To prevent erosion damage to the nozzle/orifice head, make a sacrificial hard rubber washer about 3/8" thick that tightly fits over the nozzle so that during pierce operations the high pressure splashback spray of water and garnet doesn't damage the machine over time. I used to work as a waterjet operator on Flow machines running 94ksi intensifier pumps in an industrial production setting, and without the washer there, the orifice head would be toast after a day or two of nested parts... Protect those expensive parts! :)
A sacrifice to the machine spirit must be made
This is totally Badass . Great experiment
Congrats on the views on this. This is phenomenal. I enjoyed the video but also glad to see this do so well.
Wow, I didn’t expect the Hydo to run so well. Great job mate👍
Listening to this at full volume is what tinnitus is like
except not as loud
got really bad tinnitus and yubb thats about it.
Maybe not quite that dramatic, but the frequency is about right.
yep
Can confirm.
Awesome demo and data on the testing of a jet engine; thanks; really easy to understand.
that was sicc! thanks for all your hard work and the upload, i shared
That dyno rig is 🔥

Lol idk why yt does that
As always :)
This is so damn well done that any other comments would pale at this point. WOW is the operational word here!
This guy is definitely a mad scientist whose work is awesome. Thank you.
PS: Love the music too.
Jet engines makes noise*
YT: This is definitively music
Well the way music has gone recently I can understand that.
hear hear!
@@Highlandword9 Oh you keep quiet there, Mr. McPoopypants.
This is something I thought I’d never see and it’s glorious
THANK YOU VERY MUCH FROM FINLAND !!!
This is what I call excellent professionals .... we should all be trained that way ...
When I was in the navy we ran turbines on DFM with emergency backups on JP5. Our diesel was run through fuel oil purifier and filtration. We saw a difference in power but not to the degree you saw. We also were running turbines the size of what's on a DC-10 so that probably had some affect. They were optimized for DFM.
Nothing beats the wonderful aroma of Jet-A.
revisiting this video, what a great job you did, so much attention to detail on your channel its awesome. Subbed
That water jet & jet engine......blow's me away!!! Keep up the videos!!!!
Same badass
am I the only one that becomes extremely excited when listening to that turbine spark and spool up? I have no use for it but I want one for the soundtrack alone....
Excellent video !
Very educational and entertaining !!
Yo this is absolutely amazing.
Sweet shot at 5:23! Awesome test overall and great dyno build. That hydrodiesel is weird indeed, crazy how much more power it had than the other two diesels.
Damn! Never know till now that Jet engine is so versatile in terms of type of fuel and burning. It's quite independent. It's appears that it can run on almost any flammable liquid.
The M1 Abrams tank uses a jet engine, it can run on any type of fuel. So no surprise for me
Kinda, but Jet is very similar to Diesel anyway. The military uses a single kerosine fuel for both jet engines and diesel vehicles (JP-8) to simplify logistics. I think it has an additive to give it lubricating properties like diesel.
@@haody3494 it probably uses a turbine which is similar to a jet, except it doesn't use its exhaust as thrust. And instead uses the exhaust from ignition to drive a shaft
@@Person01234 JP-8 can cause hearing problems.
Nice enjoy watching that mate , what a beast of a jet motor, jeleous 🤙🤙🤙
I was impressed at the biodiesel getting into alot of thrust at a lower RPM than the normal diesel.
Great editing on the build video. I bet that took some time to do!
Oh boy it was a little rough, the actual build wasn't too bad it just took me a long time to film the pieces to make it look easy, and get myself re familiarized with the CAM software
Great Research Experiment. One Suggestion: "Add the quantity of fuel burned by fuel type to the summary chart." Enjoyed your video. Thank you. Mike
So cool. Can’t stop smilling
Satisfying to watch, satisfying to hear
Love how powerful those water jet tables are. It blows the rust off in less than a sec.
That was dirt not rust. The metal was Aluminum, which does not rust, it oxidizes and is white.
That's abrasive grit which is added to the water jet. It's what is actually doing the cutting.
@@alanking7331 Oxidization is rust.
@@BigMacMatt3020 I know what rust is . My point at that time (8 months ago) was that he was calling the brown water that was coming off the aluminum rusty water. Aluminum "rust" is white. And I have never heard anyone call aluminum oxide as rust.
Just when you think it's reached maximum thrust... Jet Engine: Yeah right BYEEE!!!
I’m sure a lot of people were taken off-guard by how long it takes the engine from start up just to reach idle...they probably thought its idle was full thrust until he actually hit the gas.
Awesome man, pure brilliance!
This is awesome! I have been wondering if it were possible to run different fuels in a turboprop engine. I’m getting ready to drop a Garrett 331-1 in an experimental airplane and was looking at running diesel in it. Looks like it’ll need some modifications to go from jet a to diesel but it seems like it’s definitely doable with the right jetting and water injection for those short field takeoffs!
16:40 Captions : "Music"
Ah yes, human music of the human variety. My favorite.
Absolutely terrifying the first time you spooled up the jet.
Made me think how completely vulnerable one is when flying such a Bizzare and technically complicated engine.
Great content.
New Sub for sure😉🤞🚬
Except for the fact that such engines are well-tested and well-designed. May appear to be vulnerable but it actually isn't.
Holy crap!! That was awesome 👍👍
Absolutely amazing!
Very nice setup! Jet fuel is basically Kerosene. Jet fuel has less additives compared to the Diesel or the Hydrodiesel and I think that's why you would get higher RPM IE thrust. Also you higher EGT with the Jet fuel. The water cools the exhaust like water methanol injected into old turbo prop engines. I would like to see the specific gravity of the three and how that relates to thrust. Great video!
we are of the same mind set
It's almost as if Jet A is designed to be run in jets...
What a radical idea.
That's clean stuff. 6,000 rpm gain and double the power of diesel. Amazing.
278 Newton of thrust, can it be done by an electrical fan?
Occam's razor
Calm down Connar, people might hear this...
amazing test , super job
Dude you are too handy. I wish I had your tool box! Great videos! Keep it up, very inspirational
The algorithm leads us upon a path of mystery and wonder!
You earned my sub from mentioning Project Farm. I love his reviews on a lot of things.
So insanely cool!
Dude your videos have great production quality. Basass content, keep it up!
Finally some chemistry 🧪
Great job. Thank you for your efforts. Interesting comparisons.
Excellent project and nice learning about testing. Outstanding video.
Interesting that hydrodiesel performs so well. I read that they did tests with water injection into jets and it did improve performance, probably due to the water expansion.
A tip: the majority of wear that turbines experience doesn’t occur during startup or when at 100% power... its during the shutdown and resulting cool down at zero rpm. Run a blower thru it to keep the rotor spinning (not high rpm enough to keep it moving) until temps are reduced.
it"s partially true. Most of wear is during startup when RPM's are low so air velocity is also low and when fuel gets burned flames can actually touch turbine blades and burn them.
That might be the greatest thing I've ever seen
AWESOME! Great job!
HydroDiesel : Thats pretty close to how my RTX3080ti is currently acting !
Liar, no one can get those!
StarFury2 only the lucky ones
What I found really interesting is the record of EGT. Assuming higher temperatures are more damaging and shorten the time between overhaul of any given engine, Bio diesel appears to win hands down even though its power output might not be the greatest.
Thought the same, then i realized that it frosts, that´s a concern
Wouldn't jet a fuel be the best because what matter is the ratio of degrees per pounds of force. I assume you could just run it at a lower throttle and get a lower temp for the same force.
The temperature the fuel burns at would limit the thrust of the engine, as EGT is a limit. If the fuel burns hotter, you have to throttle back to avoid overheating the engine. The engine should never see EGT greater than the limit, and it's up to the operator (and programming) to avoid exceeding the limitations of the engine.
@@Knort In low altitude applications you might get away with it- mainly in power generation. If you put it on an aircraft you're in for a world of hurt. Reduced thrust is bad- you can always reduce power setting on a pure jet fuel without any of the drawbacks. On a helicopter which often has narrow power margins especially in hot weather the reduced power could very easily prove fatal. Then there's the icing risk- you'll need the entire fuel system heated. Not just because of water ice (at these water levels no amount of anti icing inhibitor will save you) but because wax will freeze and precipitate out of the diesel just like water ice, but at higher temperatures potentially. Same issue of clogging filters and the like.
Also diesel tends to build soot on the fuel injectors. Not a big issue because the injectors on a turbine are generally huge and it'll take several hours for any real buildup, but it's there and could be a pain if you aren't anticipating it.
