Aerodynamic calculation of helicopter

Anatation: The purpose of the aerodynamic calculation of a helicopter is to determine flight properties by its design parameters, to study the issues of its balancing. There are several ways to perform aerodynamic calculation of a helicopter: calculation of propeller flushing polar; theory considering the swing movements of the blades, the traction method and the power method. This article discusses the traction method and the power method, which were proposed by N.E. Zhukovsky. This method is the most frequently used and convenient method of aerodynamic calculation.
