Abstract

This report discusses the potential of pylon trailing edge blowing to reduce the adverse effects of airframe installation on the performance and noise emissions of pusher propellers. Both experimental and numerical analyses were performed, focusing on the pylon wake profiles, the propeller performance, and the propeller noise emissions. The experiments were executed in Delft University of Technology's Open Jet Facility using a scale model pylon and two propeller models (one powered and one windmilling). The numerical analysis combined an existing propeller lifting line code with analytic methods suited to predict the effects of installation on the propeller performance and noise emissions.
