How much thrust can a weedwacker @ 9000 rpm using a 24 inch diameter model airplane propeller generate?

Question

thinking about putting it on a bike will it work?

Answer 1

You'll have to know the prop pitch in order to determine thrust.

Understand that a prop will put a load on the motor and slow the RPMs.  You'll have to make some modifications.

With the motor turning fewer RPMs than it was designed for at any given throttle setting, it'll be "lugging" -- you'll need to re-jet the carb, to lean out the mixture.  To get it right, you'll have to learn to read spark plugs (google "reading spark plugs" to see what I mean).

Answer 2

its just lift vs. drag and rotation

Answer 3

You might be better using a belt drive to the rear axle.  I have seen it done and it is quite effective.  I have seen the whole prop thing done, but you need a big ol shroud and lots of clearance for a prop big enough to push you around.

Answer 4

Think about it do you want a prop 12"in front of you or behind you spinning>Belt drive>

Answer 5

definitely enough to seriously injure / kill yourself . may i nominate you for the  2008 Darwin Award ?
