摘　　要：突风载荷是民用飞机结构载荷分析的重要组成部分,民用飞机需要按照适航条款25.341的要求,完成突风载荷的设计工作。通过对比欧洲EASA条款和中国CCAR条款,分析了不同条款要求之间的差异;结合具体的工程算例,建立了突风载荷分析模型,给出了突风载荷分析的思路。对比不同条款要求发现,对于民用飞机的突风载荷设计,采用CCAR25.341计算得到的结果比CS25.341更加保守。Gust loads design is an important part of civil aircraft structural loads design.The civil aircraft loads design should include the gust loads analysis according to airworthiness regulation 25.341.Through comparing the Europe’s EASA and China’s CCAR,it gives the difference between these two regulations.Combined with a specific engineering example,the analysis model for the gust loads is established,and the way to calculate gust loads response is given.Comparing the requirements of different rules,it is found that the results calculated by CCAR25.341 are more conservative than those calculated by CS25.341 for the gust loads design of civil aircraft.
