Starting, running and driving home build jet-kart!

[ostap341]

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

[BellsAnThings]

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]

hallo again.could you tell me where do you think is the best spot to set a p 2 gauge? great job man

[berndsen1984]

@flaps20check I pickup my P2 pressure in the tube connecting the compressor outlet and the combustor input. Honestly I don't know whether this is the 'best' spot, but it gives me I fairly good impression about what the compressor is doing. Be sure to use a gauge which is not damped, so you can see exactly what is going on. I made a static pitot tube to measure the pressure.

[flaps20check]

@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?

[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.

[flaps20check]

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

[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 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 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 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?

[berndsen1984]

@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.

[KillaBeMe1]

lol i live in the middle of nowhere id get bored and build a jet cart too lol :)

[fellafoe]

thats why you dont put music on any video with a engine in it

[berndsen1984]

Fuck this, why is everybody claiming my audiosongs.. The song used was Linkin Park - In The End. And that is the last time I ever bought a song from them. Fuck you, Linkin Park, go annoy someone else.

[terror623]

they should be proud you are using their song for such a cool project :)

Mind if I copycat your bike ? :P

[a7xalterbridgerock]

dude.. this is awesome!! i rebuilt the motor of my gmc once.. but this is crazy cool. i dont have a knack for it like you obviously do though.

[rurouniyamabushi]

thanks berndsen1984..

[rurouniyamabushi]

im impressed..i'd like to ask you a few question,1.can it work w/out spark plug by using a compression ignition method? 2.can it work w/out injector & replace it wth bike carburettor(somthing more efficient)mounted before compressor housing? this is bcause sprk plug & injector need a 12vbatt which effect power to weight ratio efficiency.so please answer me,thnks.

[berndsen1984]

Ignition with a spark plug is easy, how do you want to create a kind of pressure to directly ignite diesel..? fuel injection before compressor can't be done, because you would need to dump a large amount of fuel through the compressor (10-12 gallon/hr). And you would need a giant carburettor.

By the way, the battery is also needed to power other stuff (oil pump, fuel pump, cooling fans etc.), so it is mounted anyway.

[manvstaco]

new mission dude, have a shaft coming outta the engine with a gearbox and a centr. clutch that engages at 10000 rpm, really get the power of the engine.. wouldn't be hard.. nice vid btw..

[berndsen1984]

O yes, that would be nice. Still a little difficult to build, because I would need to build a power turbine and a reduction gearbox and I don't have the right equipment for that. Still it is on my wishlist.. Maybe in the future, first getting my afterburner to work.

[steeeven1]

that is just amazing! ive been building and modding (to make it better of course) my own small jet, and i was probably gonna make a second and mount it to something like a go-kart or a big mountain bike :-) i'd love to have a go in that jet-kart lol

[VLTIM]

Ha, I've never seen anyone actually drive a kart through streets etc with cars, What if someone stepped out behind you or pulled up behind you in their car??

[berndsen1984]

Haha, well I need to have some testing ground.., but yeah, what if someone pulled up close behind me?, bad luck for the car I think. The exhaust temperature is about 500degrees centigrade. Maybe the car loses some of it's paintjob. The only worry that I had was that a truck wouldn't see me and run me over or something --> bad luck for me..
