How Jet Engines Work

A simple explanation of how jet engines work, If you want to see the full video hit up @WarpedYT YouTube, other than that I'll post the second part here tomorrow where I build a see-through jet engine.

You can really get an idea why Jet engines are so reliable because the principle is very very simple, and all there are only static parts rotating in a circular motion in place, Everything else just happens as long as you have fuel and Fire.

In the military as mechanic we always said "suck, squeeze, bang and blow"... Great little motor you have! Thanks for the video

Jet engine compressor designer here.
0:13 - that is a centrifugal compressor (I have designed several) it is BOTH intake and compression.
0:15 - Your "compression" is actually a radial diffuser and deswirl vanes. They take the dynamic pressure, produced by the centrifugal compressor, and convert it to static pressure. Rather like converting momentum energy to potential energy.

It's not the fact it's continuous flow that makes it a Brayton cycle, it's the shape of the pressure-volume curve.
Fun fact: for a while all Rolls Royce turbine engines were named after rivers because they are continuous flow

Best explanation I do in a power plant is, in a piston engine the 4 strokes happen in the same place at different times. In a turbine all 4 strokes happen at the same time in different places😉

This was the bit I was missing, thank you.
Now my F36 is a little closer to completion.

[tinytim]

Thanks for this actually made a lot more sense than previously. I'm a car mechanic so, perfect explanation for me.

The key to the whole thing is the rotating center shaft. Its one shaft with the desired stage configurations attached. Turbo jets, Turbo fans, Turbo props(propellers) are all based on a shaft with their specific parts attached.

Thank you for the concise explanation!

[briefcaseblues]

Now I understand.
Now I'm going to put one on top of my Miata

Then after Turbojets they developed Turbofans which most of your modern jets use, this introduces the concept of letting some of the airflow bypass the compressor (the relative amount is referred to as its "bypass ratio"), which actually ends up being more efficient. The principle being that thrust from turbojet exhaust alone isn't as much as the combination of having slightly less compression in the jet engine, and using some of that diverted air forced backward by the spinning turbine as thrust in itself. Very cool.

Then we can factor in reheat/afterburners, which are in no way efficient (hence they're only generally used on military aircraft), but can provide a hell of a lot of thrust! This is essentially introducing more fuel into the hot exhaust gases and focusing the explosion out the back of the plane through engine nozzles. Hold that on for a few minutes and your fighter starts getting real empty real quick!

so basically like a turbocharger but with combustion in it lol 😂 I like it

[caseycameron]

This was a great explanation the 4 stroke analogy was perfect 🤌

I am building an F-35 in my garage now. Thank you for the Info

[soundmindtv]

Awesome explanation! Makes it clear and simple. Can you go over the startup cycle?

[thomasbentley]

This is the best, most concise explanation of how a jet engine works I’ve ever seen. Thanks for posting. 👍

Rolls Royce has a good video titled Suck, Squeeze, Bang, Blow.

[NewSettlementCity]

I'm a car guy, that made it much easier to visualise as a process, cheers!

[JohnBrown-ignc]

After watching this, I'm realizing that all engines that rely on combustion of a fuel and air mixture to make power are various forms of pumps

[BillHill-mgzi]

Man, I’m so stoked I randomly stumbled upon this. I’m gonna subscribe I love learning new stuff and it probably would’ve been hard to find that elsewhere, especially since I was never gonna go looking for it. That being said I’m stoked. I found it.

Let's not forget our dear friend the Pulse Jet
