Dear WeatherCat users with an interest in how the atmosphere can be used to power our airplanes,
Hagerty's is searching far and wide for material for their enewsletters. Normally this wouldn't be of interest to WeatherCatters, but perhaps this is different. Recently they ran a story on a YouTube video showing the inner workings of a turbojet engine:

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.

As the Hagerty's author points out, jet engines are very different beasts from the engines most of us are familiar with. It turns out there is a very precise exploitation of gas dynamics and thermodynamics at work to make a jet engine produce power.
If you want a more detailed explanation, there is another YouTube done by Lesics (https://www.patreon.com/m/Lesics) which explains the process with greater clarity and detail:

Admittedly not exactly the usual sort of topic to be found on the WeatherCat forum, but interesting and polished enough that I thought many in the WeatherCat community would enjoy it.
Cheers, Edouard

One of my subscribed channels is "Agent JZ". He's a jet engine technician in the Middle-of-Nowhere, AC. Although hd is easily side-tracked, he is a fully licensed professional. So, when I saw your post I immediately visited his site and found his 'review' of the "Hagerty" vid: A See Through RC Jet Engine (https://www.youtube.com/watch?v=y3WFoxnM29c) I think it is a fair review and hope Mr. Hagerty takes the suggestions before his next tests/builds. I've used these engines all my career but learned quite a few details that were normally just colored blocks in some diagram.
