A jet engine powered gokart? Answered

Hey guys/girls, I need some assistance. for my Year 10 metalwork major, im going to attempt to make a jet engine powered gokart. I need some assistance with the plans for it. I need to find a way to make a gokart frame, acceleration and brakes, and a working jet engine powerful enough to propel the kart. any ideas are welcome, no matter how weird :) cheers

So you want to BUILD a compression jet engine? There is someone who built a jet powered go-kart here on instructable (https://www.instructables.com/id/Jet-Powered-Go-Kar...)

Maybe you could build something with a pulse jet engine? YouTube pulse jet engine and there are tons of videos that might help get your brain rolling. The acceleration problem might be solved easily with a pulse jet... don't quote me but I believe the engine is either full power or off. Best of luck and I look forward to seeing some instructable from you along the way

There are valved and valveless engines from what i understand, there is a fuel/ air mixture introduced to the combustion chamber, which is then ignited and and causes to suck in more fuel and air, the returning pressure wave then compresses the new gas that was introduced in the combustion chamber and ignited again. These engine can make A LOT of noise but here are a couple website to help expand my limited knowledge and help you understand.

Hard to believe someone who has never posted a single ible is seriously thinking to make a jet cart ............

Do please, Read and UNDERSTAND the Related projects on the right column of this page.

BTW your page says you are 16 yrs old, but this is your

"Year 10 metalwork major" you had to have started that when you were six ???

"Year 10" means their tenth year in mainstream school, not "I have been working on this project for ten years".

See the "let's make" box at the top of the page?

Use that to look for instructables on go karts and jet engines.

Well it's nice to see you've already done some research !

Still I have to ask, Have you ever attempted something like this before? (specifically the Jet Engine) I can think of a few dozen ways that it could go wrong, Even Catastrophically ! I'd consider this more of a College Physics project, maybe combine forces with someone else in your school?

Btw, Can you do some nice structural welding? (full penetration without burning through) and any experience with say a lawn mower engine or larger electronic ones? (Think ahead in case you have to change your plan later on right?)

I would Suggest you make a more classic Go Cart, and design a really nice, Custom, 4-link suspension system. Shows some engineering potential and will showcase the Metal-Working skills your teacher will be looking for :)

Either way If you can do some sheet metal forming, some fenders would be really cool ^.^

Remember to document your Ref's, take lots of pictures and stay safe !

Hope to see what you made :D

SO, As you can clearly see, There are Significant Safety Concerns.

May I suggest you shelve the jet Engine for Later?

I does sound like a Kick ass upgrade.... Down the Road :)

Tim Allen in Tool Time, He put a jet on a riding lawnmower. Those things never went very good for him.

If you get a mass to attain any significant velocity with out it being a stable configuration it will disintegrate. Whats more without a proper sturdy frame stopping will become impossible as any brakes will fail and the wheels will come off. Without any kind of protective cage when it disintegrates who ever is inside will be left bouncing across the ground attempting to absorb the velocity with their skin as a friction breaking device. All in all not a pretty picture. You can't make something that is not engineered for speed go fast safely.

From a long time ago there is a black and white short film of a guy who thought he could strap a rocket onto his back and using ice skates attain super speeds. He ended up on fire in a snow bank. Smart people learn from the mistakes of others.
