民用飞机俯仰操纵力特性设计研究

首先提出了民用飞机俯仰操纵力设计要求,结合某新型民用飞机的特点,提出了改善俯仰操纵力的相关措施,即提高纵向静稳定性、优化升降舵限偏曲线、增加电子配重、杆位移指令整形、提高俯仰操纵力等。计算结果表明,该系列措施使得某新型民用飞机俯仰操纵力特性满足适航要求,确保飞机获得满意的俯仰力特性。

Pitching control force characteristic research of the civil aircraft

First,the design requirement of pitching control fore of civil aircraft is given in this paper,then considering the characteristic of a new type civil aircraft,the measures are studies to improve pitching control fore characteristic.The measures include improving longitudinal static stability,optimizing elevator limited curve,electric balance weight,stick displacement command shaping,and improving pitching control force.The calculating results show that after using those measures,the pitching control force of the new type civil aircraft could meet the requirement of airworthiness and the civil aircraft has satisfied characteristic of pitching control force.
