| 目的 研究高空风场对飞行器飞行时级间分离的影响。方法 建立飞行器分离模型，仿真计算飞行器分离时下面级的横移距离、两个关键部件之间的间隙。结果 在最低飞行条件风速34 m/s时，下面级横移距离和两个关键间隙均满足设计条件。在仿真计算风速40 m/s条件下，下面级横移距离、两个关键部件间隙均满足设计要求，因此最低飞行条件风速可放宽至40 m/s。在最大风速45 m/s时，三个值均超出了设计值，有可能会对分离造成影响。结论 高空风对飞行器级间分离存在一定影响，随着高空风风速的增加，面级的横移距离和两个关键部件之间键间隙随之增加。 |

| The work aims to research the effect of wind field at high altitude on the stage separation of aircraft during flying. A stage separation model of aircraft was established. The sway distance of the lower stage and the gaps of two key points of aircraft after its stage separation were simulated. The sway distance of the lower stage and the gaps of two key points of aircraft all met the design conditions and requirements when the minimum wind speed and the simulated one were respectively 34 m/s and 40 m/s. Therefore, the minimum wind speed for flying could be relaxed to 40 m/s. When the maximum wind speed was 45 m/s, the sway distance and the gaps above all exceeded the design values, so the stage separation would be affected by it. It proves that the stage separation of aircraft will be affected by high altitude wind in some way, and the sway distance of the lower stage and the gaps of two key points of aircraft will be increased with the increase of high altitude wind speed. |
