Aeroacoustic characteristics of single propeller-wing configuration

The measurements were taken in the University of Bristol’s aeroacoustic wind tunnel facility. The five-bladed propeller with a diameter of D = 9” and P/D = 1 was mounted in the centre of the NACA0018 wing to create a case where the wake from the propellers impinge directly on the wing to investigate the effects of propeller-wing interaction at various advance ratios while maintaining a constant rotational speed of Ω = 8000 rpm.
