Lift and Pitching Moment Induced on Jet STOVL Aircraft by the Ground Vortex - Data Report

Abstract

The data obtained during an investigation of the effects of the ground vortex on a generic wing-body configuration are presented in this report. Circular, rectangular and thrust reverser jets were tested. The tests were conducted in the 14 by 22 foot tunnel at the NASA Langley Research Center. The tests covered a range of heights above the ground, forward velocities, and ground belt speeds.
