舰载机全机落震试验是在实验室环境下测试舰载机着舰时结构动态载荷、动态响应以及机载设备冲击环境下功能可靠性的重要试验手段。本文提出了舰载机全机落震试验的试验方法,并对试验过程中机翼升力模拟、试验件下沉速度控制、试验件航向速度模拟及机体动态载荷测试等试验过程中的关键技术问题提出了解决方案,并通过试验对技术方案进行了验证。最后通过全机落震试验系统验证了试验方法的可行性及有效性,为舰载机着舰动态载荷及响应的测试提供了可行的试验方法,并为舰载机研制提供可靠的试验数据。

Full scale aircraft drop test provides an important tool for testing the dynamic load and dynamic response of the aircraft structure and studying the function reliability under impact situation in a laboratory environment. An approach for full scale aircraft drop test is proposed in this paper. Solutions to critical technique issues arising in the testing process such as wing lift simulation, aircraft sinking speed control, aircraft horizontal velocity simulation and aircraft dynamic load testing are also derived. The feasibility and effectiveness of the test method is verified by the full scale aircraft drop test system. The test method proposed can be used for testing the dynamic load and response of carrier-based aircraft landing vibration, pro- viding reliable test data for the design of carrier-based aircraft.
