N2 - The influence of blade-vortex vertical miss-distance and angle of attack on the helicopter blade-vortex mechanism of interaction is investigated using large-eddy simulation (LES). A large-eddy simulation is carried out for a quasi 3-D blade-vortex interaction (BVI) problem, for a subsonic flow M = 0.3 and a chord based Reynolds number of 1.3×106. Computations are carried out to investigate the influence of angle of attack (α = 0 0, α = 50, α = 100) on the aerodynamic coefficients and acoustic field. It was observed that the blade-vortex vertical miss distance and angle of attack has significant influence on the aerodynamic coefficients and acoustic field.
