YouTuber Builds Working 3D-Printed Turbojet Engine and Tests It in His Attic
I feel like claiming it is "working" and "3d printed" are tenuous at best.<p>It did work... for several seconds before it melted.<p>It was 3d printed... except for the turbine, shaft, bearings, and combustion chamber which were made of metal, and the structural components which were cast from ceramic.<p>Also, FWIW, the description of the how the turbojet came to be at the beginning is pretty grossly incorrect. It is sort of like how in grade school they say that planes fly due to the Bernoulli's principle. If you are interested to learn about how jet engines actually work and the technical details that go into them on youtube, I highly recommend AgentJayZ [1]<p>If you want to see a youtuber make an actually good turbojet, check out these channels:<p>-Игорь Негода [2] His videos are in russian, but are by far the most technically advanced and performant. I watch them with the auto generated/translated subtitles<p>-Tech Ingredients [3] This is a traditional turbocharger based design, but is presented in a wonderful way packed full of interesting tech details<p>-Colin Furze [4] The turbojet that inspired this video. Much more focused on presentation than tech details, but worth watching for the comedy at least!<p>[1] <a href="https://www.youtube.com/c/AgentJayZ/playlists" rel="nofollow">https://www.youtube.com/c/AgentJayZ/playlists</a><p>[2] <a href="https://www.youtube.com/watch?v=I7GFAbtsQKs&list=PLyyfwUFI3XU8JWC1l3YLrv53ZD5l3cb8V" rel="nofollow">https://www.youtube.com/watch?v=I7GFAbtsQKs&list=PLyyfwUFI3X...</a><p>[3] <a href="https://www.youtube.com/watch?v=JzwfzgfJiJ4" rel="nofollow">https://www.youtube.com/watch?v=JzwfzgfJiJ4</a><p>[4] <a href="https://www.youtube.com/watch?v=Gh34A0b8MrE" rel="nofollow">https://www.youtube.com/watch?v=Gh34A0b8MrE</a>
