GYROPLANE TAKE-OFF METHOD Russian patent published in 2008 - IPC B64C27/02 

FIELD: flight vehicles.

SUBSTANCE: gyroplane take-off method include a maximum driving up the lift rotor by the running power plant with the minimum angle of total pitch to rpm exceeding the flight magnitude, cutting of the lift rotor, increasing the thrust to the maximum and take-off run on the surface. Here, the lift rotor is kept neutral or at a negative angle to the flow, the total pitch of the rotor blades has a minimum magnitude. Unsticking is effected on reaching the required speed by increasing the total pitch the lift rotor to the flight magnitude or to that exceeding the above by a safe difference.

EFFECT: higher safety of take-off, higher power efficiency of gyroplane.
