Abstract

The non-linear disc vortex theory of main rotor is submitted for hovering and vertical takeoff of helicopter. Integral equations were derived. These equations are used for calculation of the field of induced velocities in the main rotor disk plane and in the main rotor slipstream, when the specific rotor load distribution is given.
