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。
The aerodynamic characteristics of the ejection lifesaving system were analyzed and a set of engineering calculation methods for rapidly obtaining the aerodynamic characteristics of the ejection lifesaving system was developed. The aerodynamic characteristics of the large-angle-of-slip sliding angle at a high angle-of-attack of an aircraft’s ejection lifesaving system were calculated. The results show that the calculated results are in good agreement with the wind tunnel test data.
