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 light weight, simple and economical electric utility aircraft, a new composite structure design and verification method is proposed. The load transfer of the aircraft is analyzed theoretically. The aircraft structure is modeled by CATIA, and the strength is calculated by using PATRAN / NASTRAN. Based on the calculation results, the design of the composite ply is optimized and the 2D drawings are used to finish the design Figure A series of mechanical tests have been carried out on the components and complete machines of the composite materials used to form a set of rapid experimental verification methods for light aircraft. According to the characteristics of different types of parts using different manufacturing processes, so that production costs and effective control of the cycle. The results of the design, the validity of the test data and the reliability of the process quality have been confirmed on the Ruixiang RX1E electric two-seater aircraft, whose performance meets the design specifications.
