Abstract

The paper discusses problems of numerical simulation of high-speed maneuverable helicopter rotor aerodynamics. The effects of spatial airflow about the main rotor blades; development of vortices in the reverse flow region; unsteady nature of the distributed and integral aerodynamic coefficients of the rotor; induction in rotor systems, in particular coaxial rotors are considered in the context of a new-developed mathematical model, which is based on the time-accurate non-linear vortex theory. Numerical analysis results of the main rotor forces and moments are presented for high flight speeds and g-loads. A comparison of calculated and experimental results for a large-scale main rotor model is given.
