Air Powered Car

For gearing it's better to avoid simple ratios like 100:25 (4:1) as it means the same gear teeth keep encountering each other. It's better to use relatively prime numbers such as 101:23 and then every gear tooth gets to encounter each tooth on the mating gear which promotes better wear.

It needs a flywheel

It’s weird that it sounds like an engine even though it’s just compressed air

Roadster 2020 with spacex package is way behind!

Ever considered buying a metal lathe, it could revolutionize your strategic approach to all kinds of designs. ;)

Here's an idea. Open the car's tank at sea level, then close it again so it's at sea level pressure. Take it to a higher altitude, then see if you can power it just of the difference in atmospheric pressure.

Where do u learn all this??

maybe use belts instead of gears, since that requires less precision. also, why not add a separate flywheel on a different ratio?

Belt drive!

2075: we have air powered cars

If you treat it like a train, you could simply keep the back wheels on track and just have the one push rod giving the wheels their power from the engine. This idea will probably just get jumbled with the rest, but I love your designs so far. And it's been turning it great! I know you'll get this thing running amazingly!

The car looked like it was going to work amazing in the first test, I did not anticipate the torque issue. I should have guessed because "air hogs" cars had a metal flywheel, which must be there to overcome this problem. Is there a reason you didn't just wrap some rubber bands around the wheels for traction? Plenty of people use them for "tires". They are also great for drive belts, which would have been less work and probably more efficient than the gears. You could probably make a CVT using one as the drive band.

wait... YOU ARE AN AEROSPACE ENGINEER!??! congrats... props.... you know

Everybody gangsta until you get this on recommended two years later

I want your engine how to buy it

Okay, so, why not add a flywheel onto the small gear that runs next to it? It's hard to explain but you can make the axle coming out of the motor a bit longer and add a flywheel to it so you won't need other solutions. Or use a GT2 or related closed-loop belt. They are used in 3D-printers and work really well and don't have play.

Tom i think if the engine work at 30 psi suppose then fill the bottle as high u like just use the pressure control you already built to maintain it around 30 psi using any micro controller

I have build a lot of lpe's (lego pneumatic engines) and I always find that the best power to air consumption is produced by a 2cilinder , maybe you should try buil a second engine and just conect the drive shafts . I have to mension that I dont know if the power/air consumption is going to improve with a 3d printed engine as you heve more air leaks

what's flywheel
