Modeling the Propeller Slipstream Effect on Lift and Pitching Moment
55th AIAA Aerospace Sciences Meeting
A semi-analytical prediction method is presented to predict the effect of the propeller slipstream on the lift and pitching moment of a propeller-powered aircraft. The method assesses three effects caused by the propeller slipstream: an increase in lift over the wing due to the slipstream, a change in the tail-off pitching moment, and a change in the horizontal tail contribution to the pitching moment due to increased downwash and (possibly) dynamic pressure. This prediction method is validateddoi:10.2514/6.2017-0236 fatcat:5h6kuof6dfepze7ogbnj7gnq3e
