A new transonic flow analysis program that solve the Euler equations has been developed. The program is capable of analyzing flows over aft-mounted propfan airplane configurations at arbitrary freestream conditions, including sideslip, and at various propeller power settings. This capability includes cases where each of the airplane's engines have different power settings. Extensive analysis of the propeller power effect on airplane aerodynamics and lateral and directional stability has been conducted, and some typical results are presented in this paper. A streamline tracing capability is demonstrated. To account for viscous effects, the Euler solver is coupled with a boundary-layer method. Some preliminary Euler/boundary-layer coupled results are also presented.
