摘要

舰载机全机落震试验机翼升力模拟是在实验室测试飞机着陆载荷时,给飞机动态施加飞机着陆时刻机翼升力,模拟飞机着陆真实受载,机翼升力施加是否合理是全机落震试验成功与否的关键技术。本文给出了全机落震试验机翼升力模拟准则,提出了一种适用于全机落震试验的模拟机翼升力加载方法。根据该方法介绍了机翼升力加载装置设计原理,并对设计的机翼升力模拟装置进行了力学性能测试。将此方法和装置应用于某型飞机全机落震试验中,分别从施加模拟机翼升力大小、飞机姿态影响、下沉速度影响和着陆能量吸收四个方面对全机落震试验机翼升力模拟方法进行验证和评估。试验结果表明,该方法符合全机落震试验升力模拟准则,可用于舰载机全机落震试验。

Abstract

Wing lift simulation during full scale carrier-based aircraft drop tests is to impose a dynamic load on an aircraft’s wing under indoor environment, so as to completely simulate the real wing load-bearing of the aircraft under landing condition. Whether or not applying wing lift is reasonable is the key of successful full scale carrier-based aircraft drop tests. Here, the simulation criterion of wing lift for full scale carrier-based aircraft drop tests was given, a simulating wing lift loading method for full scale carrier-based aircraft drop tests was proposed. According to the proposed method, the design principles of a wing lift loading device were presented, the mechanical performances of the wing lift simulator were tested. The method and the device were applied in the full scale aircraft drop tests of a certain aircraft. This method was verified and evaluated from four aspects including applied wing lift values, effect of aircraft attitude, effect of going down speed and landing energy absorption. The test results showed that the proposed method satisfies the simulation criterion of wing lift for full scale carrier-based aircraft drop tests; it can be used to simulate wing lift loading for such tests.
