| 摘 要： | 针对国内弹射救生领域现状,设计了一种适合于国内某型座椅的弹射救生系统稳定板。运用计算流体力学(CFD)数值计算方法,对改装稳定板前后的人椅系统进行了高速流场下的静态和动态特性分析,并与风洞试验结果进行对比,两者吻合较好。改装稳定板前后的数值计算对比表明:在不对俯仰和滚转性能产生不利影响的情况下,稳定板的改装对人椅系统的偏航性能有比较明显的改善。六自由度动态计算比较真实地模拟了弹射出舱的过程,也进一步验证了稳定板对改善偏航稳定性能所起到的作用。数值计算完全可以应用于弹射座椅的气动研究,同时稳定板的设计对工程上的应用具有一定的参考价值。 |

| Abstract: | According to some rules aim to the situation of escape system field,a feasible type of stabilization fins for the domestic ejection system is designed.In this paper,a numerical calculation approach based on CFD is presented to analyze the static and dynamic characteristics of the seat/occupant system with and without fins in a high speed.By comparison,the results of seat/occupant system without fins agree well with the wind tunnel experiment data.The results compared seat/occupant system without fins with s... |
