Quick mechanical question
« on: May 22, 2007, 11:11:04 AM »
I'm working on a hovercraft project with some friends, and we're trying to figure out the best way to take the power output from an 11hp engine and turn it 90 degrees.

Specifically, it's a vertical shaft engine, and I want to use it to drive the propulsion prop.  My thought is that the best solution is probably a bevel gear setup, but rather than hand make something, can anyone suggest an easy pre-made item that can be retasked?

Right now I'm considering a differential from an ATV, seems like that could do what I need pretty handily, but if there's an obvious car part that can handle a 10hp 100% duty cycle and happens to be cheap, it's worth picking your brains first.

Use it for the skirt fan.

Get yourself a man's engine for the drive fan.
Attach "wings" and change it into a ground effect vehicle.
Much more fun/scary.

:)





Not me... but I want one. :O

I try to limit my flight in ground effect to take-off and landing, heh.  Pretty cool, though.

Well in that case, hovercraft.com may still help you. They've got all kinds of parts, plans, engines, etc. May be your best bet. Can't think of anything you'd pull off a car that would leave an 11hp engine with the kind of performance you'd want.
