CURRENT STATE OF METHODS FOR CALCULATING THE AERODYNAMIC CHARACTERISTICS OF HELICOPTER LAEOUTE ELEMENTS
Author: Urii Onyshkin
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.
