Abstract

The method of calculation of field of induced velocities in the main rotor disk plane and in the main rotor slipstream the based on non-linear disc theory is submitted in the paper. The calculated plot of the streamline of air jet and result of investigation oj parameters of the streamline of air jet at hovering and vertical takeoff of helicopter are submitted.

Keywords:
