So, as I’ve said before, my brother is a bad influence. I’ve drunkenly ordered parts to make the most ghetto jet turbine ever.
Now it’s not quite as ghetto as the above pulsejet trolley, but it’s pretty close considering the complexity of an actual turbojet. Now before I embed the next picture, I want to cover something blindingly obvious. It is a plastic ducted fan. Yes. Will it melt? Don’t care. It only has to operate for a very short time.
This is just the primary compressor. So it’s going to be in front of the flame anyway. It’s also going to be separated buy a good space of ceramic from the final stage compressor.
Now this is cheap made in China kind of stuff we’re dealing with. Is it balanced? Probably not. Will it survive the first run? I hope not. I really want to see this fail, but if I get a nice clean run just once I’ll be over the moon.
Details are still in the air, but I’m basically going to use this aggressively pitched fan with a fair whack of torque to suck in oxygen etc as fast as possible. Separating this from the next compressor will be a ceramic tube filled with straw like tubing to calm the turbulence a little before it hits a much faster spinning but less aggressively pitch secondary compressor. Now drunk me may have this backwards, but that’s what I’m starting with. After those will be another straw can to try and get the air into something resembling an attempt at lamelar flow and then straight into the combustion can. With enough air speed and fuel, we may get lucky and create actual jet propulsion. If not, it’s going to sound AMAZING! for about 30 seconds.
High framerate cameras, long fuel lines, remote power, chemical fire extinguishers etc. etc. and staying WAAAAAAAAAY the hell back on launch is my obvious go to for safety here.
