Homework Statement
I've been trying to find a simple equation for calculating the lift (or thrust) of a RC helicopter and I've found a few that are different.
Homework Equations
1) Lift = circular area swept by rotor blades [itex]\times[/itex] density of air [itex]\times[/itex] velocity of air exiting disk [itex]\times[/itex] velocity of air exiting disk
2) Thrust = 2 [itex]\times[/itex] air density [itex]\times[/itex] length of rotor blades 2 [itex]\times[/itex] induced velocity
The Attempt at a Solution
I am unsure which is the correct equation. Also, can someone explain what 'induced velocity' is please?
thanks!
