How Jet Engines Work

An inside look at how jet engines work. Most modern jet propelled airplanes use a turbofan design, where incoming air is divided between a large fan and the jet engine core, where combustion happens.

Aeronautical engineer here.
This is the best reference video on jets I have ever seen. And I'm pretty sure I've watched most of them haha. Great work my friend.

[Andrew-bdmp]

THis is one of the best animations i have ever seen. the easiest visualization of a pretty complex thing.

[mattrittman]

Excellent visualization and presentation! Very easy to understand. Keep up the great work and you’ll be well on your way to a million subs!

[UDEMF]

Great job. I am a commercial pilot, for 13 years, always wished something like this existed. If you dont mind, Id like to show this to all my cadets, who had a very blurry idea of how a Turbo Fan really works

This video makes me so sad because I just found it, and then discovered you only have 3 videos on your channel. My gosh your content is beyond exceptional! I hope you are able to see how talented you are...making the complex simple and clear is so amazing, and you do this better than anyone I’ve seen on YouTube. Thank you for these amazing videos and now I just have to wait and hope hope hope (“hope” repeated intentionally) for more!

[NotWhatYouThink]

Hey Jake, this was a very well-done video.
Great animation and explanation. Keep it up!

[LunarcomplexMain]

can you imagine, "ah yes, so you set the air on fire and it go... but what if we set the air on fire twice, maybe it go twice?"

[zimmmco]

Aero combustion chief technical scientist here. This is truly one of the best videos I have seen explaining this topic.

[TritonTv]

That was the most badass turbine engine graphic and explanation i have ever seen.

[teabagginganthills]

This was by far the clearest, easiest to understand, and best animated explanation I've seen yet. Thank you!!!

[pushingthrottles]

I'm a commercial pilot. Many are commending the quality of this animation along with your presentation. I agree with them! Granted, it takes a lot of time making those animations as well as the research into it. The quality though is worth it and I wonder why did you stop making videos for YouTube? Please return, and as an incentive, I've subscribed to your channel.

[leevons_home_vids]

I just discovered your videos and all I have to say is PLEASE MAKE MORE! You explain this so simply yet so thoroughly that it makes total sense. I could never understand fully how a jet engine worked but this explained it so well.

Pilot here. Been flying jets for 22 years and I've never heard the cowling referred to as the diffuser. The diffuser is usually the "cookie cutter" looking thing after the turbine stage and can be seen while looking in the tailpipe.
Also, the combustion chamber is basically a diffuser with a lot of holes poked in it, to ensure the air is at the right speed and condition for burning

Other than that, everything was very accurate. Good video!

[TravellingAllen]

Your ability to animate these incredibly complex concepts and explain them in a succinct way for a general audience is simply unbelievable. I really hope that you receive the amount of views and followers that you deserve. Just incredible work all around… thank you so much for this free knowledge.

[PARABOLA]

I currently work on CFM56 aircraft engine, your animations really help me fully visualize how they work. Thanks.

[riversetimoshrum]

This is why I’m happy to grow up with internet, everything I don’t understand I can look up for free. Very nice to have such high quality animations and presentations

[greensakaar]

As a A&P rated mechanic I have to say this is the best explanation/video I’ve seen and the only thing that could make it easier to understand is if things were explained more linearly (front to back)

[Encorous]

As someone who's just about to finish Thermodynamics and is studying aerospace engineering, this is beyond badass. Thank you!!

[marchthemonth]

Just a quick add about the "hot turbines", it's not just the metallurgy and coatings that allow the turbines to stay in their solid metal form instead of liquid (which they certainly could be at the temperature of the gas coming out of the combustion chamber), there is a lot of uncompressed "cool" air being "injected" to the core of each turbine and then bleeds out through many, many precise and small holes in the hot turbines. This keeps the turbines cool throughout their normal operation.

[oneafrica]

The best visualization I've seen about turbo fan engines. Awesome!
