摘要: The two-dimensional coupled implicit Navier-Stokes equations and standard k-ɛ viscous models are used to simulate the angle of attack characteristics an integrated hypersonic vehicle with a hark head configuration under three kinds working conditions: inlet cut-off, engine through-flow, ignition. Influence each component on aero-propulsive performance is discussed. It concluded that longitudinal static stability good, there enough lift-to-drag ratio satisfy flying requirement vehicle. At same time, it important change configurations upper surface airframe improve
