What determines the minimal vertical rate of descent during /140 helicopter gliding?

Answer 1. The vertical rate of descent descent during helicopter gliding is found from the formula V^eg = V ^ sin 0, i. e., it depends on the velocity along the trajectory and the gliding angle. The velocity along the trajectory depends on the forward or aft tilt of the coning axis. The gliding angle is determined by the lift force and depends on the main rotor pitch: the larger

the pitch, the larger the lift force, and the smaller the gliding angle and the vertical rate of descent.

What determines the minimal vertical rate of descent during /140 helicopter gliding?

Answer 2. During helicopter gliding the vertical rate of found from the formula V^eg = V ^ sin 0. Since during a glide force is the weight force = G sin 0, the work of the weight time will be the equivalent power supplied to the rotor

Hence

Thus, the minimal vertical rate of descent in a glide depends on the flight weight and altitude. The gliding velocity along the trajectory should be equal to the economical speed for horizontal flight.
