摘要: |
针对某型号运载火箭的防雨密封要求,研究了一种兼顾防雨密封效果和施工周期的防雨密封技术,主要在铆钉连接处、螺钉连接处和舱体外表面搭接缝隙处实施防雨密封措施。将此防雨密封技术应用于实际铆接舱体,产品经过淋雨试验考核,舱体内表面未出现漏雨漏水等情况,验证了此防雨密封工艺的有效性,目前该技术已应用于该运载火箭铆接舱体的生产。 |

Abstract: |
A kind of rain proof sealing technology was studied, which considered both the effect of rain proof sealing and the construction period. The rain proof sealing technology is applied to the actual riveted cabin products. After the rain test, there is no leakage of rain and water on the interior surface of the cabin, which verifies the effectiveness of the rain proof sealing technology. At present, the technology has been applied to the production of riveted cabin of a carrier rocket. |
