A WIND TUNNEL FREE FLIGHT TECHNIQUE TO DETERMINE LIFT AND DRAG OF A WING CONFIGURATION.

Abstract

Free-flight hypersonic wind-tunnel tests were made with thin delta-wing configurations to ascertain the feasibility of such a testing technique. A unique launcher system was developed that is capable of regulating the initial flight path angle, initial angle of attack, and the injection velocity. The aerodynamic coefficients of lift and drag were deduced from the recorded free-flight trajectories. Agreement between theory and test results were excellent. It is quite apparent that this testing method is a valuable and realistic research technique. (Author)
