The invention provides a pre-pressing pneumatic sealing rubber structure, and belongs to the technical field of airplane aerodynamic configuration surface sealing structure design, a resin-based carbon fiber composite material core plate of the structure is of a curved-plate-shaped structure, one end of the resin-based carbon fiber composite material core plate is a fixed end, the other end of the resin-based carbon fiber composite material core plate is a lap joint end, the fixed end is fixed to one aerodynamic configuration surface, and the lap joint end is fixed to the other aerodynamic configuration surface. The lap joint end is freely lapped on the aerodynamic configuration surface on the other side, and the lap joint end has a preset pre-pressing amount relative to the fixed end. The structure meets the pneumatic sealing requirement during large-order-difference relative movement between adjacent components of the aerodynamic configuration surfaces, the structure is simple, the weight is light, the cost is low, installation is convenient, the spanwise length can be customized according to needs, the fixed end is fixed to the aerodynamic configuration surface on one side, and the lap joint end is freely connected to the aerodynamic configuration surface on the other side in a lap joint mode. When adjacent parts on the two sides of the aerodynamic configuration surfaces move to any position relatively, the pre-pressing pneumatic sealing rubber structure is in a forced deformation state, and the lap joint ends are forced to be pressed on the aerodynamic configuration surfaces.
本申请提供一种预压气动密封橡胶结构,属于飞机气动外形面密封结构设计技术领域,该结构的树脂基碳纤维复合材料芯板为曲面板状结构,树脂基碳纤维复合材料芯板一端为固定端,另一端为搭接端,固定端固定在一侧气动外形面上,搭接端自由搭接在另一侧气动外形面上,搭接端相对于固定端具有预设预压量。该结构满足气动外形面相邻部件之间大阶差相对运动时的气动密封要求,结构简单,重量轻,成本低,安装方便,展向长度可根据需要定制,固定端固定在一侧气动外形面上,搭接端自由搭接在另一侧气动外形面上,由于采用预变形,两侧气动外形面相邻部件相对运动到任何位置时,预压气动密封橡胶结构都处于强迫变形状态,迫使搭接端压紧在气动外形面上。
