- Abstract
The hypersonic flows of high attack angle over HTV-type aircraft were simulated by solving NS equations with slip boundary conditions using AUSM+UP scheme. The topological structures of hypersonic flow-field based on the limiting streamline of surface and sectional flow patterns perpendicular to the body axis were analyzed. The results show that with the angle of attack increasing from -10 degree to 40 degree, the structure of limiting streamline of leeward surface changes for non-separating to separating which occurs form the combined-point. At the same time, the aerodynamic channels couples strongly and the separating area of upper wing surface increasing with the angle of attack increasing.
