Home built turbojet engine

Who was it that moved the trailer, or had their trailer moved a few years ago at the gnf'S?

 

What does it weigh

I have an aluminum flat bottom boat looking to test a life insurance policy

 

That is so freaking cool!!!

 

Dayum Blake!!! Wondered what you'd been up to of late.

 

Hmmm...divorce club member....no shit....

 

Nice fab work man!

 

What. Where is the YouTube enforcement around here. This is not a motorcycle related video? Just because it's cool it gets a pass?
Kidding.

Because it's really cool.

Damn there are some talented and smart people in here.

I wanted to see flames thought.

 

You have GOT TO measure the thrust at WOT.

Seriously. I would love to see thrust data after playing with exit nozzel area.

What are you using as fuel?

 

Pretty much everything was the tricky part lol. Fortunately there's software to figure out ideal hole area for primary, secondary, and tertiary holes in the combustor. I'm not that smart
All the 3/16" steel flanges were a bit of a nightmare as I only have basic tools and was adamant about doing everything myself, so I cut/drilled with mostly just an angle grinder and drill press. Including the turbo flanges, there's six in total, turned out decent but talk about a time killer.

Here's a pic of the flame tube before being slid into the engine:



It started life like this:

 

That's not me although I heard there was someone on the beebs that built something similar a while back? I'm in Woodstock.

Haven't really measured anything, probably doesn't push much since this design is pretty inefficient with all the twists and turns of the airflow. The traditional types with axial flow would probably make a lot more for the same inlet size, I'd imagine. I've really only run it at idle speeds as when I ramp up the throttle/boost the oil starts to get frothy from boost pushing past the journal bearings I guess.

 

Whole setup might be about 100 lbs with the frame and stuff.

Regular propane from a bbq size bottle.

Me too! I need to run it at night but I've been trying to be nice to my neighbors, so I'm waiting until it gets dark earlier. But I can definitely get it to shoot fire (briefly) it's probably just not good for the turbine blades. Trying to keep the explosive stuff inside the engine for now

 

On the one we built we would get a flame until we spun the turbo up to a higher speed (using compressed air). The flame would retract and disappear inside the "turbine" area of the turbo. Again, we didn't have an exhaust nozzle on ours.
In direct sunlight it was very difficult to see the flame but the "turbine" would glow red until the flame retracted.

 

Bullshit

 

OK.

When are you adding an afterburner? That would be mega sweet.

 

Your next assignment is a pulse jet.

Bang, bang, bang, bang, bang, bang,

 

Pulse jets are even louder. With less thrust!

 

Why not invite the neighbors over to enjoy it?

 

Indeed! Tell them you'll provide the hot dogs and beer.

This is absolutely brilliant - great work!

 

Is there a down side?
