As the weight lifted is the same whatever the forward speed, so is the lift of the blades. Hence a constant rotation speed gived the same airspeed to the blades.JC why does the rotor spins at the same rpm regardless the gyro airspeed ? (at constant G load I mean)
But as Vance said, the rotor rpm increases a bit when the forward speed is increased.
This is due to the increase of the stalled zone (see a previous post): a little more rpm is needed to compensate for this loss of cL.
