The report presents the results of wind tunnel test BVWT 057 performed in the Boeing Vertol VSTOL wind tunnel on an isolated 3-bladed cyclic pitch propeller with a total activity factor of 480. The primary objectives of the test were to determine the pitching moment capability from the propeller over a wide shaft angle range from 0 up to 120 deg through the transition flight regime of a tilt wing aircraft and, the effect of cyclic pitch on power. The effects of cyclic pitch on propeller thrust, normal force, yawing moment, and side force were also measured.
