飞机装载状态对机轮载荷和起降安全性影响的定量分析

飞机的装载状态直接决定了飞机的起落架压缩量和机轮载荷,同时起落架的压缩量还影响着飞机的起降稳定性。本文分析了机轮载荷的理论值偏离实测值的原因,利用解析几何方法对理论算法进行修正,开发了基于Visual Basic的飞机起落架压缩量与轮载分析程序,对各种可能的装载状态进行分析,得到了各状态的机轮修正载荷和起落架稳定性参数,计算结果与实测值吻合的较好。

Quantitative Analysis of the Effects of Aircraft Load Status on Landing Gear Wheel Loads and Takeoff-Landing Stability

The compression amout of aircraft landing gear and the wheel loads are produced by the load status,and the takeoff-landing stability of the aircraft is affected by the discrepancy between the measured and the theoretical results of the wheel loads.In this paper,the deviation of the calculated and the measured wheel loads is analyzed to revise the theoretical algorithm in an analytic geometry method,with which a visual basic program is developed to analyze the possible aircraft load status to get the correct wheel loads and the landing gear stability parameters.This program’s output corresponds well with the measured values.
