Ideas for propelling small hovercrafts( using a 18000 rpm motor)?

Question

anything soon please

Answer 1

a small hovercraft??  u mean something that just hovers  ?  or do u want it to be able to life something

i would try using the most powerfull  leaf blower u can find and attaching 3 of those to a lifeboat make 3 small tubes and put those underneath the boat ( dont forget to inflate the boat   attach the blowers to the tubes   start the blower  and the air should blow thorugh the tube onto the ground thereby lifting the boat   ( this might work  i saw it on tv lol)

Answer 2

How small is your hovercraft? Because ... 18,000 RPM is a h**l of a speed and no propeller/rotor can spin faster than the tip of it reaches the speed of the sound. For a propeller of about 40 inches diameter, that would be something like 3,500 RPM; the speed most air-cooled boxer aircraft engines have as maximum RPM.

Good luck with your project but ... maybe you should read more about propeller design before wasting much money to something that might be dangerous.

Answer 3

a flymo hover mower should do it
