Ahmed, S. R.; Yin, J. P. Aerodynamic and aeroacoustic interaction in the helicopter flow. (English) Zbl 0989.76073 Aerotec. Missili Spazio 78, No. 3-4, 103-113 (1999). 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.
