固定翼舰载机的全机落震试验

Full-Scale Drop Test of Fixed-Wing Carrier-Based Aircraft

固定翼舰载机的全机落震是飞机设计和研究的关键技术之一,舰载机应通过在试验室实施的全尺寸飞机落震试验,考核飞机在各边界着舰条件下的强度。飞机起落架和机身各部件应承受巨大的冲击载荷而不产生结构失效,以此验证机体的结构完整性。基于对飞机设计和试验规范的分析研究,本文给出了全机落震试验的分析方法和工程解决措施。

The full-scale drop of fixed-wing carrier-based aircraft is one of the most essential technology of naval aircraft design and research. Navy＇s carrier-based aircraft must undergo fullscale drop test in the test lab, to verify the strength of carrier-based aircraft under all critical carrier landing conditions. Both landing gear and fuselage must withstand that tremendous impact forces without structural failure, to demonstrate the structure integrity of the airframe. Based on analysis of criteria which should be considered to the design of carrier-based aircraft, this paper describes analytic procedure and engineering-oriented solution for full-scale drop test.
