Abstract : A mathematical model of the rotor wake in the vicinity of a rotorcraft fuselage is formulated taking into account the mutual interference between the rotor and fuselage. It is assumed that the vortex sheet behind each rotor blade rolls-up into a single, blade tip vortex and that the fuselage can be represented by constant source potential flow panels. The velocity field given by the combined rotor wake and fuselage model is presented for the case of a Sea King helicopter in forward flight. (Author)
