Large-amplitude high-rate roll experiments on a delta and double delta wing

Abstract

A comprehensive wind-tunnel test program on both a 6 5 O delta and an 80°/650 double delta wing model has been recently completed. The program included static and dynamic force tests. high speed flow visualization and free-to-roll tests. A brief description of the various experiments is presented, as well as results that demonstrate the value of the previously proposed hypersurface representation of aerodynamic loads in the nonh e a r and unsteady regimes.
