The invention provides a pneumatic sealing rubber, which belongs to the technical field of airplane structure sealing and comprises a mounting section, a groove area and a working section, and the groove area is positioned between the mounting section and the working section. And the mounting section is an area for fixing the rubber and is connected with an aircraft structure through a fastener. The working section is an area where the pneumatic sealing rubber is attached to the structure to achieve the purpose of pneumatic sealing. The groove area is of a semi-circular groove structure, and the working section can be bent through the semi-circular groove structure, so that the working section can adapt to structural deformation. And an included angle is formed between the working section and the mounting section and is an obtuse angle. The pneumatic sealing device is simple in structure and capable of achieving shape follow-up design, and the pneumatic sealing requirement of the joint of the fairing skin, the fuselage and the wings is met.
本申请提供一种气动密封橡皮,属于飞机结构密封技术领域,包括:安装段、凹槽区和工作段,凹槽区位于安装段和工作段之间。安装段为固定橡皮的区域,该段通过紧固件与飞机结构连接。工作段是气动密封橡皮与结构贴合以达到气动密封目的的区域。凹槽区为半圆槽结构,半圆槽结构使得工作段可以弯折,使工作段得以适应结构变形。工作段安装段之间存在夹角,夹角为钝角。本发明结构简单、可随形设计,满足整流罩蒙皮和机身、机翼对合处的气动密封要求。
