Abstract

The invention discloses an aircraft connecting structure based on bottom curtain board interface crimping and an aircraft. The aircraft connecting structure is applied to the aircraft, the aircraft comprises an aircraft cabin and a load, the aircraft connecting structure comprises a switching support, the switching support and the load are contained in the aircraft cabin, the center area of a front end flange of the switching support is fixedly connected with the load, and the periphery of the front end flange is connected with the aircraft cabin. The adapter bracket and the aircraft cabin can be separated; and the bottom shielding plate is fixedly connected with the flange at the rear end of the adapter bracket and seals and covers the cabin opening of the aircraft cabin, and after the adapter bracket is separated from the aircraft cabin, the load is separated from the aircraft cabin through the cabin opening. Therefore, the separation interface can be simplified, the separation reliability can be improved, and meanwhile the method is suitable for a light large-area thin-bottom curtain board structure. The periphery of the bottom shielding plate is in lap joint with the cabin body, a flexible buffering heat insulation material is arranged in the lap joint area of the bottom shielding plate and the cabin body, and the heat sealing performance of the lap joint position is guaranteed.

本发明公开了一种基于底遮板界面压接的飞行器连接结构和飞行器。飞行器连接结构应用于飞行器，飞行器包括飞行器舱体和载荷，飞行器连接结构包括：转接支架，转接支架和载荷容置于飞行器舱体，转接支架的前端法兰的中心区域与载荷固定连接，前端法兰的外周与飞行器舱体连接，转接支架和飞行器舱体之间可分离；底遮板，底遮板与转接支架的后端法兰固定连接，并封盖飞行器舱体的舱体开口，在转接支架和飞行器舱体之间分离后，载荷通过舱体开口从飞行器舱体脱出。由此可以简化分离界面，提升分离可靠度，同时适应轻质化的大面积薄底遮板结构。底遮板四周与舱体为搭接连接，在底遮板与舱体搭接区域设置柔性缓冲隔热材料，保证搭接部位的热密封性。
