FIRING UP THE TURBOJET!

We test our first turbojet engine with propane fuel and explain how we intend to use such engines to drive low speed high torque output turbo shafts.

It's a Stationary Fuel to Noise Converter!
I'd wish I had neighbors like you.
I'd rather hear turbine whine than bumping car stereos.

Used a small turbo because "the smaller the turbocharger, the more difficult it is to get it to operate". This guy doesn't mess around. Great work, and thank you for explaining everything so well. Love your attention to detail, this is an awesome project. Would be cool to see how much energy you can extract from both the pressure + heat of the exhaust, maybe drive a steam generator for cabin heat or wing de-icing in whatever vehicle your jet engine goes into!

You are an extraordinary man. So meticulous, so precise, clearly enjoying these technical builds and sharing information. Very, very cool!

Unless you're specifically recording ambient sounds, you guys should use the lav mic all the time. Sounds a lot better...

You need a compressor bypass to unload the turbine (you'll get higher rpm's and better pressure ratios, by keeping the compressor out of surge) and a better flame holder to help stabilize combustion (you can hear it chattering, and see the boost pressure bouncing all over)

Your idea for thrust measurement is questionable, at best. The exhaust jet will entrain a not insignificant amount of air into the stream before making the bend, and the wall friction of the flow will come into play, so you will not be getting accurate measurement of thrust available. It will, however, be repeatable, so if you're only looking for verification of tuning changes, then it'll work fine.

lapel mic sounded best. you should use that exclusively moving forward.

I've been waiting on this since the last week where I binge watched your channel. Very satisfying to see the turbo finally run! The idea to use a fuel pump for the oil is actually genius.

That’s the best designed, built & executed turbocharger-based gas turbine engine setup I’ve ever seen; & great video outlining the turbo-jet principles… Huge applause, dude… easy to see you’re a perfectionist 🤙👏

The neighbors must love you guys. Keep up the great content!

[blackturbine]

It's surging horribly
You need to add a compresson bleed valve on the compressor outlet to reduce surge on low compressor rpm

*Tech Ingredients* YOU are a modern day and interesting "Mr Wizard"
Looking forward to your video on Pulsed Detonation Engines (PDE) as I still have yet to see a homebuilt version that generates sustained thrust or runs at over 10hz continuously.

Nice to see someone in my age group having fun!
Keep on having fun.

[fun_ghoul]

Definitely the right weather for max-power pulls!

[bsideadventures]

Youre channel is so under appreciated. You've got great content

[johnkesl]

Love your work!! That part about waking up the wife was priceless.

[AndreLuiz-ipfh]

Maybe the best and most reliable turbojet convertion on YouTube. Congrats

[tbxmb]

Amazing Video as always. Now i have to build one too.

[ssgoldwater]

This is seriously so awesome, thank you for taking the time to build it and record it all to share!

[jasonflt]

I wish you were my shop teacher back in high school!

I loved the thinly veiled sarcasm towards neighbours, but especially the misses. There was even a wry smile when you said about the misses. Very impressed with the turbojet too.
