民用飞机校验机动仿真研究

Research on the Checked Maneuver Simulation of Civil Aircraft

校验机动是民用飞机纵向俯仰机动中的一种,它是机翼、平尾等部件的载荷严重情况之一。对于校验机动的分析国内国际上的主流是采用机动仿真法。美国的FAR和欧洲的CS适航条款对校验机动有着不同的要求,FAR指定了俯仰角加速的要求,没有指定俯仰操纵器件的输入;而CS则指定了俯仰操纵器件的输入,对俯仰角加速度没有要求。以往国内校验机动一直以FAR条款为设计基础,对于CS条款的研究和分析不多,以欧洲CS条款为基础,对校验机动的仿真分析进行了研究。

Checked maneuver is one of the longitudinal pitch maneuvers of civil aircraft, which is the critical load condition of wing and horizontal tail. For checked maneuver analysis, maneuver simulation method is mainly used domestically and internationally. The FAR and CS regulations have different requirement for the checked maneu- ver, FAR specifies the requirement of the pitch acceleration rather than the pitch operation input, while CS speci- fies the pitch operation input rather than pitch acceleration. Domestically the checked maneuver is analyzed accord- ing to the FAR regulation, there is not much research and analysis on the CS regulation. This paper conducts ma- neuver simulation research on the checked maneuver according to the CS regulation.
