| 目的 在地面条件下更真实地模拟弹箭外表面电器接插件在雨、雪、雾等高湿度条件下的飞行环境，方法 利用数值分析方法，通过综合对比相同喷嘴结构下不同出口尺寸的外流场形态、不同压差下喷嘴出口流量等计算结果，确定喷口尺寸和工作压力。通过涡流黏度云图，确定接插件与喷嘴的相对位置关系。通过建模对喷淋方案进行效果预测后，搭建配套试验系统，并在石英灯加热器热辐射环境下开展高温高湿度耦合环境实效模拟试验。结果 试验中加热条件能够满足飞行过程中的表面温度及总加热量要求，水气环境模拟达到1.82 mm/min条件。试验后，对参试产品进行阻值测试、剖面碳化层厚度测量和热解产物分析，表征电气特性良好。结论 所述试验方法能够同时有效模拟高温高湿度飞行环境，能够对雨、雪、雾等高湿度条件下的接插件产品的飞行可靠性进行有效评估。 |

| This paper aims to more truly simulate the flight environment under ground conditions with high humidity conditions such as rain, snow and fog on the outer surface of the bullet and arrow electrical connectors. using numerical analysis methods, by comprehensively comparing the calculation results of the outer flow field shape of different outlet sizes under the same nozzle structure and the nozzle outlet flow rate under different pressure differences, obtained the required nozzle size, pressure and relative position. After predicting the effect of the spraying scheme through modeling, the supporting test system was established and a high temperature and high humidity coupled environmental effective simulation test was conducted under the heat radiation environment of a quartz lamp heater. The heating conditions in the test can meet the requirements of surface temperature and total heating during flight, water vapor environment simulation reaches 1.82 mm/min. After the test, the resistance value test, the thickness measurement of the carbonization layer of the profile and the analysis of the pyrolysis products were conducted, and the electrical characteristics were good. The test method can effectively simulate the high temperature and high humidity flight environment at the same time, and can effectively evaluate the flight reliability of connectors under high humidity conditions such as rain, snow and fog. |
