An investigation has been conducted to demonstrate the use of the Green's function method to study potential incompressible helicopter aerodynamics with particular application to rotor wake effects on hub/pylon flow. The theoretical formulation for incompressible potential aerodynamics with separated flow presented here is incorporated in the computer program SHAPES (Subsonic Helicopter Aerodynamic Program with Effects of Separation). Extensive numerical results are shown which illustrate the flexibility and accuracy of the formulation. Comparisons with several existing analytical and experimental results are made. (Kursetz)
