Analysis on Hypersonic Unsteady Aerodynamics and Dynamic Performance of an Lifting Body Hypersonic Vehicle

摘要

The purpose of this paper is to simulate the unsteady aerodynamics andrnflight dynamic of an lifting body hypersonic vehicle at hypersonic conditions. Thernflow simulation use an advanced structured time-accurate Navier-Stokes equation.rnDual time-step approach in conjunction with LU-SGS implicit method was utilized.rnRoe scheme which was in combine with stiff moving grid generation technologyrnwas used for spatial discretization. The CFD/RBD coupling algorithms setup thernfoundation for vehicle dynamic aerodynamic analysis and virtual flight simulation.rnFrom the aerodynamic and flight dynamic results, the dynamic stability of thernvehicle have been studied.
