负过载下某型弹射手柄材料偏硬对飞行安全的影响分析

Analysis of Influence to Flight Security due to Superhard Material of Certain Ejecting Handle on Negative-g Condition

某型引俄弹射手柄国产化后材料偏硬,在负过载飞行过程中,由于飞行员双腿与手柄之间的干涉,存在座椅意外弹射的可能。本文通过建模计算结果与现场实测数据的分析对比,理论上否定了此可能性的存在,克服了采用试验验证的困难。

The material of certain handle on ejecting seat from Russia is harder after localization,and possibility that the seat is unexpectedly ejected exists because of the interference of legs and handle while flying in negative-g.By contrast the model calculation results with the data measured on-the-spot,that possibility is denied theoretically,which has overcome the difficulty in testing with experiments.
