Starting, running and driving home build jet-kart!

Here I present my next video about my home build jet kart! In this video I made a compilation of some videos I took over the last few weeks. You can see me starting the engine, running the engine and driving my kart for the first time! I reached an average of 40km/h during a 1.5km piece of road, so some tweaking of the engine is needed.

now all that's left is the wings and control surfaces and you got yourself a airplane :D

So all is a car turbocharger compressing the air and then feeding that in to a flame chamber which mix with fuel and create thrust in simple, btw i was planing to make a jet engine plane a rc one

@flaps20check The angle in my flametube is not especially meant to accelerate the hot gases. The angle is simply needed, because the diameter of my flametube is a lot bigger than the entry hole to the turbine. The angle is just to push the gases in the right sized hole. A 70mm inducer should produce enough thrust to move a light kart. My turbo is 75mm inducer and 90mm turbines exducer. Don't expect to go flying, because moving a kart with thrust takes some time to get up to speed.

@berndsen1984 i saw in another video of yours where you show how to build a jet engine,a picture from yours flametube and in the end of the flametube ,you have cut it and rebuilt it with an angle ,to accelerate thehot gases?Is it good to do this and in the end of the cap of the flametube?Do you believe that a well designed jet engine with a new turbo(wheel inducer 70mm and turbine exducer 80mm) can produce enough thrust to move a light kart? thank you in advance?

@flaps20check You mean where should you make the funnel to fit the flametube to the turbines inlet? There's no optimum I think. I made it in the combustion chamber, so I would'n lose to much heat, it was easier to build and because I could make the flametube swappable.

[flaps20check]

@berndsen1984 yes someone suggested it to me but they have a very small oil flow .Something more.If i make the combustor in the end going to the turbine with an angle to accelerate the gases,i should do it and in the flametube like yours in the end,or both of them?thank you

[berndsen1984]

@flaps20check I never tested the full pressure, but my pump can maintain 70 psi, even when the oil is hot. I have a 12V gear pump. There are cars which use electric 12V pumps for power steering, which would make a great oil pump for you, but I don't know which cars use this setup.

[flaps20check]

@berndsen1984 yes me too.what pressure does your pump reach ?

[berndsen1984]

@flaps20check I created the pitot tube out of a piece of copper tubing, look at wikipedia on how to build one, there are pictures which say more than my words. It is very difficult to find an oil pump which is 12V and capable of producing enough pressure and keeping up the flow, when the oil heats up. The guy at who I purchased my pump is no longer producing them, so I would go for a powersteering pump from a car and drive it with a 12V motor. I also heard good words about a shurflo pump.

@berndsen1984 very clever, otherwise you would meter only the static pressure.how did you make the static pitot tube?Furthermore i would lke to ask you, which do you think,the oil pressure should be for a turbo with 70mm wheel inducer(big enough).I cant find a 12v oil pump capable of producing over 60 psi of pressure.Do you duggest anything?
