Propellers used for electric vertical takeoff and landing (eVTOL) aircraft propulsion systems experience a wide range of aerodynamic conditions, including significant incidence angles relative to oncoming airflow. Propellers in oblique flow exhibit deviations in thrust and torque oriented along their axis of rotation, as well as significant off-axis forces and moments. Although important for understanding eVTOL aircraft aerodynamics, sparse experimental data exist for propellers operating at incidence. This report describes an experimental wind tunnel study of isolated propeller aerodynamics across a wide range of flight conditions expected to be experienced by the LA-8 tandem tilt-wing, eVTOL aircraft. The experimental data obtained from the study are graphically presented and a discussion of observed aerodynamic phenomena is compared to theoretical expectations and past experimental work. The content of this report is intended to provide guidance to future propeller testing efforts and describe pertinent propeller aerodynamic behavior expected to be experienced by eVTOL vehicles.
