飞机着陆状态对轮载信号触发时间的影响分析

Analysis of the impact of aircraft landing status on the time to trigger the Weight on Wheel signal

摘要:

轮载信号是飞机相关系统进行空地状态判断的重要信号,轮载信号触发时间对飞机各系统工作状态具有重要影响。本文依据动力学方法,初步建立了飞机从机轮接地至触发轮载信号的动力学模型,分析了飞机着陆状态对轮载信号触发时间的影响,对于飞机相关系统设计工作具有一定参考价值。

Abstract:

Weight on Wheel(WOW) signal is an electrical signal which plays an important role in confirming the air/ground condition of the airplane during landing phase. The time to trigger the WOW signal has important influence on the working condition of aircraft systems. Preliminary dynamic model from touchdown to the WOW signal is triggered was established according to dynamics method. Based on the dynamic model, the impact of landing status was analyzed. This model may have some reference value on the design of related aircraft systems.
