ABSTRACT

Given in this paper is the method of computation of helicopter rotor elastic blade motion in the general case. Comparisons of the results of computations based on the present method to the results of wind tunnel and flight tests are presented. The method can be used in the determination of aerodynamic and aeroelastic characteristics of main and tail rotors for a wide range of problems concerning helicopter aeromechanics.
