 Abstract

An experimental and theoretical investigation is described of the flow above and downstream of a 76° delta wing and two double-delta wings (sweep 76°/60° and 76°/40°, respectively, kink at 50 % chord). The flow pattern is visualized employing a laser-light-sheet technique. For the case of the delta wing experimental results are compared with numerical results of a free-vortex sheet method for computing three-dimensional flow about slender wings, a free-vortex sheet method for the limiting case of conical flow and a computational procedure for computing two-dimensional time-dependent vortex wake roll-up. Based on the laser-light-sheet investigation a vortex-sheet model is proposed for the flow about double-delta wings with leading-edge vortex separation on both wing panels. Presented as AIAA Paper 82-0949 at the AIAA/ASME 3rd Joint Thermophysics, Fluids, Plasma and Heat Transfer Conference, June 7-11 1982, St. Louis, Missouri, USA.
