An Engineering Method for Estimating the Lateral/Directional Characteristics of V/STOL Configurations in Transition

摘要

A method for estimating the power induced increments of side-force and yawing and rolling moments in the transition speed range is presented and compared with available data. The study shows that in addition to the expected inlet effects and the lateral shift in the induced downloads on the body and wing there is a large favorable sidewash induced at the vertical tail as well as suction pressures induced on the leeward side of the body that add significantly to the side-force and rolling and yawing moments.
