Corrections from Joexer (a subscriber) 1:28 When Running Properly, fuel in an aircraft cylinder engine should not explode; An explosion or detonation is a malfunction and is very damaging to the engine. 1:57 - 2:25 While you are correct about the cooling and aerodynamic aspects there is also a huge aspect of efficiency, ease of manufacturing, maintenance, "ideal conditions", power to weight, fuel and metallurgy technologies and even vibration certainly come into play. 2:29 Maximum speed is not the sole benefit of a different engine technology. 2:32 Rocket engines are actually more efficient in some ways than turbojet engines under the premise of speed per fuel and weight. It is more propulsively efficient because of its light weight and small size for the weight with a propulsive efficiency of about 70%. 2:47 Jet engines is a poor choice of words because a rocket engine is a kind of jet engine. You seem to have conflated it with turbine engine. A Jet engine is any kind of reaction engine, that discharges a fast moving stream of mass to generate thrust. A Rocket engine or even a Pump-jet, as may be found as propulsion on a boat are both jet engines. The aeolipile dating to around 150 BC was also a jet engine. A Turbine engine is merely one such kind of jet engine. 4:01 A Ramjet is not a turbine engine as it does not make use of a turbine for compression 4:32 Modern Fighter Jets do not use Turbojets, they use Low Bypass Turbofans which are the previously mentioned turbofans with less bypass. Its also not very powerful. 6:02 This is not accurate. A ramjet is only like a rocket in the sense that it is a Jet engine. Unlike a rocket a ramjet is airbreathing and uses relative wind to the aircraft to slow and compress the air, then, it adds fuel to and ignites. It cannot function like a rocket and does not have oxidizer. Ramjets also begin producing meaningful thrust around .5 Mach at sea level (384mph) Also this misses a LOT of huge elements like, maintenance, economic factors (like fuel costs), distance, the mission requirement, aerodynamic drag, the limits on each kind of propulsion, other efficiencies, temperatures, density altitude, manned aviation concerns like pressurization, heat and time for the pilot, also you did not mention Lift, Bernoulli's, Otto cycle (Piston) or Brayton Cycle (Turbines) and perhaps greatest of all, The inevitable tradeoffs that result from anything that expends energy.

During the Second World War there was a test aircraft in Switzerland which was powered by a wood gasifier. It was called AC-4 (HB-USI) and required 34kg of wood per flight hour. 😀 The aircraft still exists today and can be viewed in the Flab & Fliegermuseum in Dübendorf.

The videos are amazing, very interesting and very easy to understand. I wish this video was made 5 years ago, because at that time I had a project about aeronautical technology museum for a college assignment. I think this video can really save my time.

A very interesting type of piston engine used in aircraft for some time was the rotary engine, where the whole engine rotates and the crankshaft remains stationary. The Wankel engine has also been used in aircraft as a proof of concept. The Pulse jet concept was also used in planes although again not very successfully.

During WWII the Germans and Japanese experimented with Pulsejet engines as well but they were mostly used in explosive ordinance. There were some prototypes/ concepts using the Pulsejet and it is pretty interesting. Especially the Japansese Kamikaze jet.

Incredible. Thanks for visualization and animations of these engines, since it's much easier to understand that way.

This one is way more informative than I had thought. Thanks for greater understanding.

I was wondering for a very long time about all this engine types... Thank you

Thank you very much for the Chinese subtitles, which has greatly helped the group with poor English and the high-quality popular science of aircraft engines!

Concerning the SR-71, at speeds above Mach 2.5, the spikes on the front of engine intake retract reducing airflow into the compressor and diverting it around to the exhaust where the afterburner ignites the fuel with it. I believe the process is gradual to prevent a flameout. At maximum speed the engines are operating as ramjets.

The best video I have ever seen about aircraft propulsion system. Interesting, simple, easy to understand and concised yet detailed information.

thank you for the explanation, the explanation is very easy to understand and the animation is very good. I as a teaching teacher about aircraft have been greatly helped by the videos that you and your team made, I hope you and your team will continue to work for the world of education. let me also download and make teaching materials for my students. thank you

You didn't include the 5th type, the rotary radial, but you showed it on the front of the Sopwith saying they used this for cooling. Rotary-radial engines are quite different from radial engines, and should of had their own part and animation in this video.

Great video, breathtaking animation! Thanks a lot.

This video is very helpful. Thanks a lot. Can you please make a video which includes the questions that mostly asked during interview for an aircraft technican. I mean technical interview questions. That will be a great help for a lot of people.

I like how simple it is and easy to understand all in all.. tho willnyou ever make a video on variable cycle engines? They're not a common sight but basically they can change from turbofans to turbojets on the go, mostly prototypes for fighter jets

I wanted to shout out the propfan: an experimental engine that could be described as a cross between a turbo fan and a turbo prop. It looked like a jet engine with propellers attached to the back. They ran a few experiments, but the advantages never emerged, and it was extremely loud.

This is the best explained cylinder engine motor vid

Well explained and well documented. Keep it up 👍

There is also the pulsejet, like the one used in the German V1 during WWII. Basically it is a tube with a self-resonant combustion chamber.

the video was so good 💯💯 , i was looking for this kind of video only for my research works . loved it thank you very much for this video pls make more video like this .

A quick note: the turbine section is generally considered a stage of a turbojet engine. Same with an afterburner if equipped.

One of the most beautiful video that I've ever seen

I have only a 1: 4 Scale Corsair, but the Radial with 250ccm - what a Amazing Sound ! ( want to build the Black-Bird out of carbon.. 1: 5 Scale! Great Video thx !!! 👍🏼🇦🇹✌🏼

One note about the turbojet / turbofan. Turbojets on mil aircraft were phased out in the 50s / 60s. All modern fighters use turbofan engines, just with different bypass ratios than the ones used on big planes.

thank you needed this making me self a rc with an good plane prop engine

Belle présentation simple ,concise ,et instructive. Merci

Very nice presentation, and informative for engineer's.

These "Turvo"prop engines are awesome!

Amazing.thnx so much.i really enjy and like this video.i love to watch new advancement in aviation technology.

I want to become an aircraft mechanic and this is a great video!

Excellent explanation 👏 please do more videos on aeroplane parts 🥰

very well organised and explained, love it. learned a lot, tnx dude! waiting for more educational content like this from you. cheers 🖖 by the way you made all this engine animations yourself?

Very useful. Easy to understand video. Thank you!

Love this video Detailed, good explained Perfect

Thanks for the illustrative presentation.I gained a lot from your video

I learn something useful today,

Very nice video, fun, easy to follow, very interesting and information. This mans underrated.

good vid, u should ve talked a little more about ion propulsion, its really interesting from what I ve seen.

Thank you Would’ve been nice to include how some of these engines start. Especially the jet engine.

شكرا جزيلا.. بارك الله فيكم 😇🌸👍

Very interesting video

Excellent bien que très rapide donc très général (au point de contenir quelques erreurs de simplifications). Les sous-titres en français sont disponibles (il faut les activer.)

Excellent Video - very well explained.

I have a glider with a Wankel rotary engine, ASH 31 Mi, which is selflaunching.Works great! 😄

The ion propulsion is not that new we use it in satellites for decades but we cannot use it in our atmosphere that is the new nice job that you mentioned it and great video :)

WOW SIR, THANK YOU SO MUCH. I GUESS THAT YOU MAY NOT BE FROM AMERICA OR THE UK (THE ACCENT). IT HELPS US TO UNDERSTAND, AS WE ARE INVOLVED IN HELPING PEOPLE AND NATIONS EVERYWHERE.

Thanks For share Knowlege in Sample words.

There are also 2 subcategories of turbojet engines; the ones that uses axial compressors and the ones that uses centrifugal compressors(centrifugal is still used on small turboprops or on turboshafts-one of my my favourites centrifugal engine is Rolls-Royce NeNe Mk10 used on T33 military aircraft)

One type that is used or was used is the pulsejet engines. They may still be used on model planes but they are very loud and the fuel consumption is very high. They powered the German V1's. Also, in model aircraft, there are ducted fan powered by internal combustion engines or electric motors.

Tanks for the simple explanations! Would be awesome if you could make a Video only for the scram-jet-system. There are only a few ones on YT and they haven’t really good animations.

Amazing explanation learnt a lot thankyou bro

Thank you soo much sir for your great informmation.

In the piston engines you show a radial in the animation the engine in the biplanes shown flying is a rotary engine.

You are missing Deltic engines used by German Reconn a/c during WW2 (Jumo 233) --as well as RRs and submaringes Nathan Price developed an axial flow gas turbine (J-37 - likely in 1937) beginning with a steam turbine, then adapting to kerosene. He also developed turbochargers to improve piston engines, and saw how a simplified diagram of a turbo charged piston engine can be easily simplified by removing the pistons.

Great video! Very well put together.

Thank you!

This is really well done.

Very interesting video. I like it. Profesionally. Maybe w/GPL combustion. hybrid, nuclear, etc.

Excellent 3D presentation. A sub and like for that.

Beautiful 🎉🎉

Beautiful explanation! 💯

Thank you, this is very educational.

Great stuff ! The steam plane really was a surprise !

Thank you so much

Am very impressed...Thanks bro

Very informative

thanks for the nice and interesting video clip !

Very informative video thanks.

Stupendous video, you should have mentioned the scram jet

Fantastic video, very well done

Great video! thanks for sharing! I would like to ask you, what software did you use to make this animation? I would appreciate it if you could answer!

Thanks for this information , I wish successful for you forever ❤️

Would’ve been very interesting to see the pulsewave detonation engine

Excellent Animation

The Plasma Jet Engine, the one China is trying to take credit for even though they weren’t the ones who created it. The SCRAMJET by Boussard (I think that is the company’s name) that can go in space too. Magneto-PlasmaDynamic Jet Engines etc

U r simple a superb explainer 👏

damn well explained as always

very good i enjoyed watching would like to see more

I can't seem to find the answer to a certain question ❗ How the heck the entire blade-array rotates 360? Does a motor do the job? Or any other power source is used! What force/energy is being used to rotate those blades which compresses the air and then blah blah blast it through the nozzle? Somebody save me 🥴 By the way this video is really great, I mean it. ❤️❤️❤️ I mean you explained the Ramjet in a way more simplified way! Thanks for it.

I guess the most powerful and efficient engine in the world is motivation of Human. Your video is the best fuel.

If you do have information, I'd like to hear about Pulse, Rotational and Oblique detonation engines

amazing information keep going

Very good presentation...no other disturbing bgm....❤️

Regading your engine configuration, while the „opposed“ piston engine or flat-engine has two pistons that simutaniously combust the one you showed is technically a 180° V-type.. but enough wining.. the animation is really nice!!

Thanks

The images and information are great.

Great video

Very interesting video. Well done!

So amazing video... Keep doing more 🔥🔥

謝謝視頻

thanks

I in engines you didn't mention, there is the pulse detonating engine. I think that one counts as different from the rest.

Please make a video of how we csn make glider parts at home love you ☺️

The fuel/air mixture does not "explode", it burns, at a rate of 26000 FPS. The reciprocating engines on aircraft are very light weight

Great content as always

wonderful video thank you

Well done.

I think the scramjet engine would be cool to include. especially since it was in top gun maverick with the darkstar.

Great clearification
