基于气动热约束的高超声速电缆罩封头外形优化设计

Optimization of Cable Fairing Former Structure Submitted to Aerodynamic Thermal Constraints in Hypersonic Flows

基于N-S方程数值计算方法对高超声速气流中导弹电缆罩封头和其后方的电缆罩外形进行气动热计算,对2种封头外形的气动热进行对比分析,研究了其流动机理和流场结构。结果表明:优化后的与后方电缆罩等宽、等高的封头外形极大地降低了电缆罩的热环境。

The hypersonic flow around the former structure of cable fairing is numerically simulated based on Navier-Stokes equation.Aeroheating fluxes comparison between two cable fairings is made.Flow field structure and flow mechanics is analysed.It is found that the aerodynamic heating of optimized design is greatly reduced than the original cable fairing,whose height and width are the same as the former structure in it.
