Hello all...
I have a question about an engine-driven propeller. While a propeller is being spun, the air resists it and the maximum power of the engine will turn at "max rpm" when the drag from the air interacting with the propeller becomes equal to the torque generated by that engine.
Now imagine that you replace the prop with an IDENTICAL one, except that it half the weight (less dense material).
What happens to max RPM and why?
Conversely, imagine adding a propeller that is IDENTICAL except it's twice as heavy... What happens to max RPM in this case?
Thank you!
