The PMAL3D computer code has been extended to an aircraft configuration with propellers by embedding a nonlinear actuator disk theory developed by Conway in the PMAL3D inviscid/viscous interation code developed at AL/IAR/NRC. The actuator disk model was coupled to PMAL3D by introducing the timeeveraged velocity field induced by each propeller actuator disk as a modification of the free stream. The theory of the panel method, integral boundary layer method, and the actuator disk model are briefly presented in the present paper. This study has included both propeller and viscous effects on the aerodynamics of an aircraft and presented detailed numerical analyses and discussions of the aerodynamics for the Aurora configuration.
