Abstract:

Tests were made of a large-scale tilt-wing deflected-slipstream VTOL airplane with blowingtype BLC trailing-edge flaps. The model was tested with flap deflections of 0 degrees without BLC, 50 degrees with and without BLC, and 80 degrees with BLC for wing-tilt angles of 0, 30, and 50 degrees. Included are results of tests of the model equipped with a leading-edge flap and the results of tests of the model in the presence of a ground plane. Author
