A numerical study of the effect of side winds on the main rotor and tail rotor performance during hover was conducted for a closely spaced two-blade main- and tail rotor configuration. The method used was an unsteady panel method. The interaction between the simultaneously rotating rotors was investigated on the basis of stream lines, velocity vector plots and unsteady main- and tail rotor lift. The wind azimuth was varied over the range of 0 degrees to 330 degrees. The findings of the work are in good agreement with experimental work and phenomena explantations found in the literature.
