The invention provides a composite fairing butt-joint frame sealing structure which comprises a fairing butt-joint upper frame, a fairing butt-joint lower frame, a sealing layer, a plurality of explosive bolts, an explosive bolt box and a gasket, and the sealing layer is located in a gap between the fairing butt-joint upper frame and the fairing butt-joint lower frame. The fairing butt-joint upper frame and the fairing butt-joint lower frame are connected through the explosive bolts, explosive bolt boxes are arranged on the peripheries of the explosive bolts, gaskets are arranged below the explosive bolt boxes, and the gaskets are located in a gap between the fairing butt-joint upper frame and the fairing butt-joint lower frame. According to the design method of the composite fairing butt-joint frame sealing structure, main influence factors and secondary influence factors in mutual extrusion and deformation coordination of the structures are distinguished, the design key points are grasped, the design period is shortened, and the design cost is reduced.

    本发明提供了一种复合材料整流罩对接框密封结构,包括整流罩对接上框、整流罩对接下框、密封层、若干的爆炸螺栓、爆炸螺栓盒以及垫片,所述的密封层位于所述的整流罩对接上框与整流罩对接下框之间的间隙中,所述的整流罩对接上框与所述的整流罩对接下框通过所述的爆炸螺栓相连,爆炸螺栓的外围设置有爆炸螺栓盒,所述的爆炸螺栓盒的下方均设置有垫片,所述的垫片位于整流罩对接上框与整流罩对接下框之间的间隙中。本发明所述的复合材料整流罩对接框密封结构的设计方法区分了结构相互挤压、变形协调中的主要影响因素和次要影响因素,抓住了设计要点,降低了设计周期和成本。
