FORCE AND MOMENT MEASUREMENTS OF MODELS OF THE ARGMA CONFIGURATION IN THE NOL 4-IN. HYPERSONIC SHOCK TUNNEL NO. 3
Abstract
Two light-weight models of missiles and a lightweight sphere are suspended by very fine threads in the test section of the NOL 4-in. Hypersonic Shock Tunnel No. 3. When the shock tunnel is fired, the threads are swept away by the initial portion of the flow, leaving the models and the sphere freely suspended to respond to the flow. With the use of a high-speed camera and a highintensity, rapid-response light source, the models and the sphere are photographed as they move in free flight in the flow. By comparison of the motion of each model to that of the sphere, the static aerodynamic moment, lift, and drag coefficients of each model as a function of angle of attack and Mach Number are determined. Seven configurations of decoy missiles were tested in this manner. (Author)
