This article analyzes the dependence of thrust and required tail rotor torque on crosswind. The problem of left self-rotation of a helicopter is emerging. Problems that require solutions are identified. A method for adaptive correction of the tail rotor pitch is proposed.

This article examines the behavior of a helicopter, the peculiarities of the psychology of flight personnel and actions in case of failure in the speed-altitude danger zone.

Designing a helicopter is an expensive undertaking. And here mistakes should not be allowed. This reguires calculation methds. Due to tht complex interaction of the main rotor with the airflow around the helicopter, severe turbulence ossurs. Therefore, to assess the aerodynamic characteristics of the layout elements suchas the wing, the fin, the stabilizer, the tail rotor, it is necessary to take into account both normal and tangential components of the velocity, taking into account disturbances in variant flight modes.

The article describes the features of helicopter behavior and the need for flight personnel to understand the procedure in case of tail rotor drive failure at various flight altitudes.
