Abstract

The aerodynamic interaction e_ects characteristic of pusher propellers were studied at the Large Low-Speed Facility of the German{Dutch wind tunnels (DNW-LLF). A propeller model was positioned downstream of a pylon equipped with a trailing-edge blowing system. Surface-pressure transducers integrated into the propeller blades con_rmed the local impact of the pylon wake on the blade loads. At an intermediate thrust setting, the sectional lift impulsively increased by 30% during the wake passage. The application of pylon blowing decreased the integral velocity de_cit in the pylon wake by up to 77% compared to the unblown case. As a result, the load uctuations during the wake encounter were practically eliminated, thereby mitigating the adverse installation e_ects.
