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