Prediction of Vortex Flow Characteristics of Wings at Subsonic and Supersonic Speeds

The leading-edge suction analogy of Polhamus, which has been successful in the prediction of vortex lift characteristics on wings with pointed tips at subsonic and supersonic speeds, has recently been extended to account for the vortex flow characteristics for wings with side edges. Comparisons of experimental data and other currently used methods with the extended method are made for wings having side edges at subsonic and supersonic speeds. Recent data obtained for a low-aspect-rat io cropped-delta wing with various amounts of asymmetrical tip rake, simulating a roll control device, are also presented.
