The invention belongs to the technical field of aircraft design, and discloses a cabin door sealing tape capable of preventing liquid leakage, a sealing joint and a fire extinguishing air.The cabin door sealing tape comprises a C-shaped body, the cross section of the C-shaped body comprises a first edge, a second edge and a third edge which are sequentially connected, and the free end of the third edge inclines in the direction away from the first edge; a boss structure is arranged on the outer side face of the first edge. Three sealing boundary lines can be formed between the cabin door sealing belt and the discharge port cabin door and between the cabin door sealing belt and the discharge port door frame, so that the sealing effect is good, and meanwhile, the sealing extrusion force of the discharge port cabin door is relatively small. The problem of leakage loss caused by overload generated by the liquid fire extinguishing medium stored in the water tank along with flight maneuvering of the fire extinguishing aircraft within the flight envelope range of task execution can be effectively solved.

    本发明属与飞机设计技术领域,公开了一种防止液体渗漏的舱门密封带、密封节点及灭火飞机,舱门密封带包括C型本体,C型本体的横截面包括依次连接的第一边、第二边和第三边,其中,第三边的自由端朝向远离第一边的方向倾斜,第一边的外侧面设有凸台结构。本发明舱门密封带能够与排放口舱门、排放口门框之间共形成三条密封界线,因此密封效果较好,同时所需排放口舱门的密封挤压力相对较小。可以有效解决灭火飞机在执行任务的飞行包线范围内,水箱内存储的液体灭火介质随飞行机动产生的过载导致渗漏损耗的问题。
