多乘员弹射指令系统延迟时间仿真计算

 指令系统延迟时间的计算尚无明确有效的方法，大多依靠实验和经验来确定。为给某型飞机指令系统设计提供依据，减少实验次数和费用，提出风险系数法，通过比较风险系数大小来计算指令系统延迟时间。计算表明，“0 0”弹射是计算延迟时间的决定性条件，其他条件则不起决定性的影响，而且，单纯依靠延迟时间不能达到有效的发散效果，还必须配备轨迹发散系统。通过与发散火箭的优化组合，该型飞机指令系统延迟时间为125 s和135 s，发散火箭总冲110 N·s，作用时间50 ms。此外，并列乘员火箭包燃烧尾焰灼伤风险很小,与实验结果相符。通过与相关数据的对比，该方法能够为多乘员弹射指令系统的设计提供有效的参考依据。

Calculation of Simulated Delay Time of Multi-crew Member Ejection Command System

So far there is not an effective and clear method to calculate the delay time of a command system, which more often than not is determined by experience and experiments. To provide reference for a command system design of an aircraft, reduce experiment time, and save expenses, a method of risk coefficients is put forward which calculates the delay time of a command system by comparing the risk coefficients. Simulation results show that "0-0" ejection is the crucial condition for calculating the delay time, while the other condi-tions are insignificant. Effective trajectory diffusion cannot be attained on the delay time alone; a track separa-tion system is necessary. Through an optimal combination with the track separation rocket, the command sys-work time is 50 ms. In addition, the risk of burn of crew members by late ejection is very small, which agrees with the result of the experiment. Comparison with the relevant data shows that this method can provide effec-tive reference for command system design.
