Numerical study of attack angle characteristics for integrated hypersonic vehicle

Abstract：The two-dimensional coupled implicit Navier-Stokes equations and standard k-ε viscous models are used to simulate the angle of Stack 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. 作者： Author： Wei HUANG  Zhen-guo WANG 作者单位： Institute of Aerospace and Material Engineering,National University of Defense Technology,Changsha 410073,P.R.China 期 刊： 应用数学和力学（英文版）   EISCI Journal： APPLIED MATHEMATICS AND MECHANICS 年，卷(期)： 2009, 30(6) 分类号： V211 Keywords： integrated hypersonic vehicle    properties of stack angle    component analysis    computer simulation    hark head configuration    aero-propulsive performance    机标分类号： V21 TK1 机标关键词： hypersonic vehicle    integrated    performance    static stability    Navier-Stokes    improve    upper    three    time 基金项目： the Excellent Graduate Student Innovative Project of National University of Defense Technology，Hunan Provincial Innovation Foundation for Postgraduate Numerical study of attack angle characteristics for integrated hypersonic vehicle[期刊论文]  应用数学和力学（英文版） --2009, 30(6)The two-dimensional coupled implicit Navier-Stokes equations and standard k-ε viscous models are used to simulate the angle of Stack characteristics of an integrated hypersonic vehicle with a hark head...
