N2 - This paper describes the multi-functional rotor noise and aerodynamics test platform at the Hong Kong University of Science and Technology (HKUST). To investigate the noise characteristics of propellers with inflow, the test rig is installed in the 2.5m × 2m low-speed and low-noise wind tunnel in the Aerodynamic and Acoustic Facility (AAF) at HKUST. The working section flow speed is from 0 to 40m/s. The test rig is attached to a turntable on the ceiling of the working section, which allows pitch angle variation between 0 ◦ (tunnel axial flow direction) and 90 ◦ (transverse direction for hovering condition), with a resolution of 0.1 ◦. The noise produced by the rotor is measured by a set of wall-mounted surface microphones. The broadband noise pattern of the rotor is measured and compared.
