Hi and welcome, in this instructable we will go through how i made a turbo jet. This is in minimal detail if you would like more detail and photos please visit my website: http://thejetman.webs.com/

Before we begin as you probably know Propane and LPG are flammable gases so be extremely careful and turbo jets can back fire or explode in certain cases. I am not liable if you or any person or your property are hurt or damaged if you try to build this.

Now for the fun stuff.

Step 1:

To make something like this you would need a well stocked tool kit which would include:


a drill to make things easier a drill press


a welder

an angle grinder

a cut off saw

of course a hammer

a few brains

and maybe a few more things.

The first thing i did was make an oil pump. To make this i used some rectangle shaped pipe, iron plates, hose, welding rods and an oil pump off a Subaru Ute. I welded the pipe to one of the plates, then drilled a hole for the oil pump to fit into( would have been easier to use an oxy). Next I had to put in the drive shaft to drive the oil pump (make sure the shaft is straight). I then had to seal the tubing using pvc pipe cement.

Great work !! Absolutely loved it :D You should measure how much thrust you can get off of it. I have an idea, you can add an iris-like adjustable nozzle for more thrust control.
Yep Put it on a cart see wot the thrust is like make it with bigger turbo more fuel and air if need be you be flying about
Amazing build!! Would you recommend adding a liquid cooling system along with a radiator to cool the water? If so, how would it go altogether? <br>Thanks!
Since I made this I have found the turbo doesn't really need water cooling if it is shutdown and cooled using a leaf blower (with the oil still flowing), which prevents any oil getting cooked to the turbine shaft.
sure would BUT....Id use something like used oils ie. cooking oil, old motor oil ect propane is way too dangerious and also can freeze your valves and stall out the vehicle in traffic or on a hill :)
Haven't had that much trouble with propane, the regulators haven't got frozen. I wouldn't be driving the jet-kart in traffic, might burn someones bonnet off! lol I have now made it, it starts on propane and runs on 80% petrol 20% diesel, currently doing a major rework of some parts.
Yes! :D
Great job! Video would be cool. Also Google Sketch-up is great for illustrating things like your drawings. It's real easy to do scale drawings and there are lots of things, like your turbo, that are already created.<br> <br> My favorite show, no longer running, is Junkyard Wars. There was an episode where they actually created and jet propelled raced cars. One powered with a very similar turbo jet like yours. The other was powered by a pulse jet.<br> <br> One of the major problems with this type of turbo is they are not designed to handle the heat generated here and will consume themselves quickly. The bearings are the weak link.<br> <br> Also, even though it is the air intake side, the rubber will quickly get too hot and burn. Try a flexible furnace pipe, or align your fittings better to use a solid pipe.<br> <br> Instead of drilling all the holes in the inner flame tube, would a tube make of expanded steel mesh work?<br>
Hi mr incredible, thanks for the info. the only thing i could find was that piece of rubber motor bike tube, when i started it the tube swelled up to about the size of a football. If you have some mesh or whatever i wouldnt really know wether it would work because of the high heat and that small holes are required first then they should increase in size closer to the exhaust end. But you may not need a combustion chamber as big as mine so you could get away with a lot less holes in the pipe. And also some other flame tubes i have seen have a lot less holes as well and they are relatively the same size.
If a blast furnace is what I think it is something for melting metal, that is a darn good idea, might need to add an after burner though to increase the heat. This thing is incredibly fuel hungry though so you would need lots of gas unless you convert it to diesel.
Hi well it can be used to make lots of noise, the exhaust gases have reached over 700'c on some peoples jets so you be the judge, or if you are just bored and want to impress your friends that's what it can be used for. Sorry their is no video i only managed to get it going once before the angle grinder died, i will try to get a video up if i get it going one day.
so perhaps you could use it for a component of a blast furnace?
what's it for?
video plz...
