Integration of Propeller Slipstreams into the Aerodynamic Analyses of Bodies 810566

The NCSU body flow computer program was modified to include the axial velocity component of propeller wakes. The energetic wake is represented by a series of ring vortices spaced along the body axis whose strengths are related to the engine power output and whose diameters are always larger than the maximum local body dimension. Agreeing at least qualitatively with limited full-scale wind tunnel data, the results indicated that aircraft drag increases linearly with power level for a given configuration.
