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.
