Hey guys!
So it's been a long time that I've been wanting to create a thread that is all about gas turbine engines, jet engines in general. I absolutely love the topic and I'm sure there are people here who love this topic too!
So I'm finally creating a thread all about turbine engines. I've been thinking about this for months, and I still don't know what to post here. Not sure if I should post a video, a question, quote or even photos...
So I decided to post a link to a channel that inspired me to study the subject, which is, of course, the AgentJayZ! One of the greatest channels on YT IMHO. :smartass:
https://www.youtube.com/user/AgentJayZ/videos A channel that is all about jet engines!
So what I want to discuss in this thread: Everything about jet engines, being turbofan, turbojet, turboshaft, ramjet, rockets, anything related to jet engines.
Please, if you have any question, picture, article, video to share, feel free to post them here! [emoji106]
Here are two pictures of the SR-71 Blackbird (one of my fav jets!) taking off (1st pic) with afterburner on, and as you can see the Shock diamonds in the afterburner flame, which are oblique shockwaves caused by the supersonic gases and the difference in pressure (abrupt pressure changes) between the exhaust gas flow and the atmospheric pressure. At low altitudes, jet engines nozzles are generally over-expanded, which means the atmospheric pressure is higher than the exit flow of the exhaust. This increase in pressure ignites basically anything in the engine's exhaust! [emoji3] Temperature and pressure in the core of the shockwave are extremely high!
I could talk about the SR-71 all day long... but anyway, feel free to post anything related to jet engines, I'm looking forward to seeing them! [emoji4]
