An Approximate Supersonic Wind Tunnel Simulator

Abstract

A technique is described wherein drag and lift measurement on models of supersonic projectiles and wings traveling on the surface of a liquid can be used to determine the approximate drag and lift of such objects when traveling through air. By this method, the velocity is scaled down by a factor of about 1000. A simple developmental supersonic wind tunnel simulator is described. The simulation and the mechanical accuracy of the apparatus is not perfect as will be evident to the precisionist. However the qualitative features of a supersonic wind tunnel are simulated and approximate measurements can be made. Considerable experience can thus be gained in supersonic flow with very simple equipment.
