动静压信号误差对飞控系统影响分析及处理方法

Analysis and Treatment on Static and Pitot Signal Error Effecting FCS

某飞机多功能探头的动静压信号未经校准,存在较大误差。本文结合余度管理逻辑对飞控系统所用信号的误差进行确认后,再进行系统纵向阻尼比、操纵期望参数、稳定储备及时域响应特性的仿真分析,明确了误差对飞行品质及稳定储备的影响,并提出了解决方法。

Static and pitot signals from multifunctional probe on an aircraft which are not calibrated have greater errors. After confirming the applicable signals used by FCS is error with consideration on redundancy management logics, this paper depicts the simulation analysis on longitudinal system damping ratio, desired control parameters, stability reserve and time domain response characteristic, further clarifies that the error has effects on the flight quality and stability reserve and provides the resolutions in the final.
