摘　　要：从总体布局、材料选取、结构设计及载荷分析等方面详细阐述了全复合材料轻型飞艇吊舱的研制。飞艇吊舱是体积较大的外挂结构,从外挂受力特点出发,充分运用了复合材料夹层结构高刚度/质量比的特性,合理地进行结构设计布局,很好地解决了大尺度复合材料结构的刚度问题。通过有限元分析和静力试验对舱体结构进行静强度、刚度验证。计算及试验结果表明全复合材料轻型飞艇吊舱满足强度、刚度设计要求,结构质量比预定质量节省10%,从而可以增加有效任务载荷或减少浮囊体积。Research and production of full composite light airship pod is particularly presented from total arrangement, material choice, structure design and load analysis. Airship pod is a big volume external structure and has its mechanical properties. Make use of high stiffness/weight ratio properties of sandwich and design ra- layout, which solves stiffness problem of full-scale compos-ite structure. The pod structure of static strength and stiffness is verified through finite element analysis and static test. The result shows the strength and stiffness of airship pod can meet the design demand, the actual weight is less 10% than fixed weight, and can add effective assignment load or reduce gasbag volume.
