A rapid design method for aeroacoustic optimization of installed propellers is described. Comparisons are made between optimizations with and without installation effects taken into account, for a 5-deg angle of attack and a wake-encounter case. The results highlight the impact of the blade count on the aeroacoustic performance, and the impact of installation effects on the optimum design.
