Dear mid-60s Buick caregivers with an interest in other types of internal combustion engines,
The folks at Hagerty's seem to have a bit too much time on their hands and thus dig up some surprising YouTube videos. Here is the article link for the jet engine video in question:
https://www.hagerty.com/media/video/how-does-a-jet-engine-work-lets-look-inside/The video is of a small turbojet engine with plastic sides which are tough enough to withstand the heat and pressure. The demonstrations are quite amazing even if you aren't into jet engines.
https://youtu.be/MgL0GW248mEAs the Hagerty's author points out, jet engines are very different beasts from gasoline and Diesel engines. It must be said, it appears that jet engines produce power in a manner that looks like a car engine working with the heads removed. It turns out there is a very precise exploitation of gas dynamics and thermodynamics at work to make a jet engine produce power. The crudest explanation is that the "head" which keeps the combustion inside the engine to power the plane is the constant compressing of air at the front of the jet engine.
If you want a more detailed explanation, there is another YouTube done by
Lesics which explains the process with greater clarity and detail:

Cheers, Edouard
