(TU Delft Flight Performance and Propulsion) Ragni, D. (TU Delft Wind Energy) Eitelberg, G. (TU Delft Flight Performance and Propulsion) Veldhuis, L.L.M. (TU Delft Flight Performance and Propulsion) Date 2016 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.
