弹射救生系统大迎角大侧滑角气动特性工程计算方法研究

Aerodynamic analysis and engineering prediction research of ejection escape system at high angles of attack and large angles of side-slip

对弹射救生系统的气动特性进行了分析,发展了一套快速获取其气动特性的工程计算方法,并对某战斗机弹射救生系统的大迎角大侧滑角气动力特性进行了计算。结果表明,工程计算结果与风洞试验数据一致性良好。

An aerodynamic analysis of ejection escape system has been presented and an engineering pre- diction method has been developed, with which the aerodynamic characteristics of a fighter ejection escape system have been calculated. The calculated results compare well with the wind tunnel data, showing that the method is feasible.
