Method is presented for computing downwash field due to vortex wake of lifting rotor in forward flight; formulation permits calculation of velocities at arbitrary points in space; suitable choice of computation points thus permits treatment of isolated or tandem rotor problems; calculations have been carried out for single and tandem rotors tested by NASA, and computed airloads are compared to experimental data; reasonable agreement is shown.
