The heavy-load airplane hatch cover frame is characterized in that the heavy-load airplane hatch cover frame comprises a hatch cover outer frame made of a carbon fiber material, an embedded steel plate is embedded in the rear portion of the hatch cover outer frame, hatch cover glass covers the hatch cover outer frame, and a glass cover frame made of a carbon fiber material is arranged on the hatch cover glass. The method has the advantages that carbon fiber modeling is adopted, the overall modeling and the structural strength can be guaranteed, and structural damage and deformation caused by self weight are avoided. And in consideration that the stress at the rear end of the whole hatch cover is far greater than that at the front end, a steel plate is added to the rear half section for reinforced support. Therefore, the self weight of the steel plate is equivalently reduced in the whole hatch cover, the weight of the front-end frame can be enhanced through the steel plate, and the problem of deformation of the frame of the hatch cover is perfectly solved.

    本发明公开一种重载荷飞机舱盖边框,其特征在于所述重载荷飞机舱盖边框包括碳纤维材质的舱盖外边框,所述舱盖外边框后部嵌入有内嵌钢板,舱盖外边框上覆设有舱盖玻璃,舱盖玻璃上设置碳纤维材质的玻璃盖框。本发明的优点在于采用碳纤维造型,既能保证整体造型和结构强度,又不至于因自身的自重导致结构破坏、变形。而考虑到整个舱盖后端受力远远大于前端受力,又在后半段加入了钢板进行强化支撑。这样,钢板的自身重量在整个舱盖中被等效缩小,而前端框架的重量又能通过钢板进行加强,完美解决了舱盖边框变形的问题。
