Computing induced velocity perturbations due to a helicopter fuselage in a free stream [PDF]
The velocity field of a representative helicopter fuselage in a free stream is computed. Perturbation velocities due to the fuselage are computed in a plan above the location of the helicopter rotor (rotor removed). The velocity perturbations computed by
