摘    要:现代飞机设计过程中,要考虑飞机遭遇突风时不同部位的动态突风载荷特性.根据大型水陆两栖飞机的设计要求,制订离散突风和连续紊流的分析流程,研究离散突风和连续紊流响应特性的程序化设计方法,并计算飞机各部位的单值载荷包线和组合载荷包线.程序化设计结果表明,大型水陆两栖飞机遭遇突风或紊流时,机体动态载荷量级与静载荷相当,且设计效率大大提高.研究结果为大型水陆两栖飞机的突风载荷设计提供了依据.

关 键 词:突风  动态响应  程序化  载荷包线

Abstract:In the design process of modern aircraft , dynamic load characteristics of different parts under gust should be considered .Due to the design demand of large firefighting amphibious aircraft , analysis flows of discrete gust response and continuous turbulence response were established ,response characteris-tics programming design of discrete gust and continuous turbulence were successful to achieve .Peak load envelope and combined load envelope of different parts were calculated by the program .Programming de-sign analysis results show dynamic loads of large amphibious aircraft under gust were the same order of magnitude as static load ,and improve the design efficiency greatly .It provides reference for gust loads de-sign of large firefighting amphibious aircraft.
Keywords:gust  response characteristic  programming design  load envelope
