飞机双垂尾载荷自平衡校准

利用研制的能够远距离、大跨度双向加载、可移动的专用液压加载设备，对飞机双垂尾加自平衡载荷进行校准研究。通过对结构受载的分析，简化了结构受载情况，论证了飞机双垂尾的左右两部分加平衡载荷同时进行校准的可行性。使用该技术，不用搭建承力架和复杂地固定飞机，而只需通过地面人工操作即可对双垂尾的左右两部分同时进行校准，能够大大降低飞机垂尾载荷校准试验的难度、风险和成本，对其它飞机此类结构的载荷校准具有一定借鉴作用。

Self-balancing load calibration on aircraft twin-finned tail

Using developed movable and special hydraulic loading equipment that can apply high-span bidirectional loads at long bowls,load calibration on the aircraft twin-finned tail has been studied by applying self-balancing load.The structures load case has been simplified,and the feasibility of the load calibration on the aircraft twin-finned tail by applying balancing loads on the both parts of it simultaneously has been demonstrated by the analysis of structures loads.This technology can calibrate both parts of...
