The invention provides a separable flow guide pipe butt joint device. The device is suitable for dynamic heat sealing between a flow guide pipe assembly and an engine which have relative displacement.The device has the characteristics of good engine drainage effect, high heat flow resistance and safe and reliable heat sealing. The device comprises a flow guide pipe assembly and an elastic heat insulation pad support assembly, the flow guide pipe assembly and the elastic heat insulation pad support assembly are installed on a back cover structure and a landing platform structure which can be connected and separated respectively and are in butt joint through the compression effect to form a heat sealing face, the requirements for engine drainage and aerodynamic heat protection are met, andmeanwhile reliable separation can be achieved along with unlocking separation of the back cover structure and the landing platform structure.
本发明提供了一种可分离式导流管对接装置,适用于存在相对位移的导流管组件与发动机之间的动态热密封,具有发动机引流效果好、抗高热流、热密封安全可靠的特性,包括:导流管组件、弹性隔热垫支架组件,导流管组件与弹性隔热垫支架组件分别安装在可连接分离的背罩结构与着陆平台结构上,通过压缩作用对接形成热密封面,满足发动机引流和气动热防护要求,同时能够伴随背罩结构与着陆平台结构的解锁分离而可靠分离。
