针对适航标准对民机横航向静稳定性的要求,提出了一种基于人机闭环数学仿真计算的适航符合性评估方法。根据适航条款的要求提出了量化评估指标,建立了飞机系统模型和驾驶员操纵模型,以实现定常直线侧滑飞行等的特定飞行任务的人机闭环数学仿真,并依据数学仿真结果和评估指标对飞机的横航向静稳定性做出评估。运用此方法完成了某型民机设计方案的适航符合性评估,并较准确地确定了飞机横航向2个静稳定导数的合理取值范围。该方法可应用于民机的概念方案设计,计算结果可为飞行试验提供理论参考。
Aiming at the requirement of airworthiness standard to the static stability of civil aircraft transverse navigation, a method of airworthiness conformity assessment based on human-computer closed-loop mathematical simulation is proposed. According to the requirements of Airworthiness Clause, a quantitative evaluation index is put forward, and the aircraft system model and the driver manipulation model are established to realize the human-machine closed-loop mathematical simulation of a specific flight task such as steady-state straight-line sliding flight. Based on the mathematical simulation results and evaluation indexes Evaluate the aircraft’s lateral stability. This method has been used to evaluate the airworthiness compliance of a civil aircraft design scheme and to determine the reasonable range of the 2 static stability derivatives of the aircraft in a more accurate way. The method can be applied to the conceptual design of civil aircraft, and the calculation results can provide theoretical reference for flight test.
