Abstract

The invention discloses a segmented aircraft skin quick connection structure and a manufacturing method. The skin includes a left section and a right section arranged adjacently, and the left section and the right section of the skin are both laid on the supporting surface of the truss , the connecting piece is a mushroom head type industrial hook and loop fastener, the length of the mushroom head type industrial hook and loop fastener is equal to the length of the skin, and the width is equal to half of the width of the support surface. The production method is to select a reasonable skin segment form; select a mushroom-shaped industrial hook and loop with a suitable load-bearing range; complete the laying and pasting of the mushroom-head industrial hook and loop on the skin; compact the mushroom-shaped hook and loop on both sides of the hook and loop Fasteners; complete the fixing of the aluminum alloy pressure plate. Through the above method, the present invention can realize repeated disassembly and assembly, which is convenient for the maintenance and maintenance of the body; significantly improves the utilization rate of the skin and prolongs the service life of the skin; simplifies the process, reduces the weight and reduces the cost.

Description

technical field [0001] The invention relates to the technical field of aircraft skin connection, in particular to a segmented ultra-light aircraft skin quick connection structure and a manufacturing method. Background technique [0002] With the development of aircraft in the direction of lightweight, the application of composite materials in aircraft has gradually increased, and it has become an important indicator to measure the advancement of aircraft structure. With the advantages of strong anti-vibration ability and corrosion resistance, it can greatly reduce the number of parts and fasteners and improve the overall performance of the overall structure. It has become one of the four major materials for the new generation of aircraft body structures. However, compared with metal structures, composite materials have weaknesses such as low interlayer strength and poor impact resistance, which determine the difficulty of assembly and connection of their structures and high ...
