Aerodynamic and aeroacoustic interaction in the helicopter flow. (English) Zbl 0989.76073

The authors investigate two problems of helicopter flow field: the aerodynamic and aeroacoustic interaction between the main and the tail rotor, and the interaction between the main rotor and fuselage. The first interaction is analyzed by a numerical approach, the analysis of the second interaction is based on wind tunnel experiments with a subscale-powered helicopter model.
