摘　　要：为了设计和制造出重量轻、工艺简单且经济实惠的电动通用飞机,提出了一种新型的复合材料结构设计和验证方法。对飞机的载荷传递进行了理论分析,采用CATIA对飞机结构进行建模,并使用PATRAN/NASTRAN进行了强度计算,根据计算结果,优化了复合材料铺层设计,采用二维图纸的形式快速完成发图。对所采用复合材料的组件和整机进行了一系列的力学试验验证,形成了一套适合轻型飞机的结构快速试验验证方法。根据不同类型零部件的特点采用不同的制造工艺,使生产成本和周期得到有效控制。设计结果、试验数据的有效性和工艺质量的可靠性已经在锐翔RX1E电动双座飞机上得到了证实,该飞机的各项性能满足设计指标要求。In order to design and manufacture a lightweight, simple technology and affordable electric general aircraft, a new method of composite structure design and verification is adopted. After analyzing the load transfer of the aircraft, the model of the aircraft structure is built by CATIA and the strength of the aircraft structure is calculated by PA- TRAN/NASTRAN. Based on the calculation, the composite layer design is optimized, and the drawings in two dimensions are issued quickly. With a series of mechanical tests for the composite aircraft components and the aircraft, a test verifica- tion method for fast testing the structure of light sport aircraft is formed. According to the characteristics of parts with dif- ferent types, different manufacturing processes are adopted, so that the production costs and cycle are controlled effectively. The effectiveness of the results and the test data are proven on RX1E （Rui Xiang） aircraft with the satisfaction of the design requirements.
