Abstract
We extend our experiments on fixed-pitch propellers in forward flight at various incidence angles with respect to the freestream, to a propeller with variable collective pitch. Different combinations of blade pitch, incidence angle, and flight speed were tested at the University of Dayton Low-Speed Wind Tunnel in an open-jet test section. All six components of force and moment were measured, at incidence angles of -10 to 20 degrees. A higher thrust, power consumption, pitching moment, and yawing moment are measured at higher incidence angles, which agrees with the previous study and literature. We suggest curve fits to capture dependency on collective pitch, advance ratio, and incidence angle, for reduction to stability derivatives, and for prediction of trends beyond just the classical thrust/torque/power coefficients. © 2025, American Institute of Aeronautics and Astronautics Inc, AIAA.
