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...【Numerical study of attack angle char】相关文章:
