摘要
从某临近空间浮空器的裙体复合材料桁架结构的需求出发,研发设计了一种大型环形碳纤维复合材料桁架结构,该桁架主体结构采用高性能碳纤维复合材料圆弧管,接头采用全复合材料设计,连接采用榫卯+粘结+螺栓连接的组合连接方式。同时,对复合材料圆弧管和接头的制造工艺进行了研究,研发制作了直径4.5m、15m、30m的裙体复合材料桁架结构,并配合完成2万m平流层试飞,获得圆满成功。该桁架产品的结构设计和复合材料制作工艺应用于某载人飞艇的复合材料骨架的设计和研制中,获得良好效果。
Abstract
From the requirement of the composite truss structure of a near space aerostat,R&D and design of a large annular CFRP truss structure were described.The main structure of truss used CFRP circular tube,the whole joint was CFRP.And the connection structure was compound of mortise and tenon,adhibited and bolt connection.At the same time,the production process of CFRP circular tube and joints were studied.And CFRP truss skirt structures with 4.5m,15m,and 30m diameter were developed,the stratospheric flight experiment of 20 thousand meters was successful completed.The design of truss frame structure and CFRP production process were applied to the development of a manned airship,and received good results.
