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。
Firstly, the design requirements of pitch control force of civil aircraft are put forward. Relevant measures to improve the pitch control force are put forward in combination with the characteristics of a new type of civil aircraft, namely, to improve longitudinal static stability, to optimize the limit curve of elevator, to increase the electronic counterweight and rod displacement command Plastic, improve the pitch control force. The calculation results show that the series of measures make the pitch control force of a new type of civil aircraft meet the requirements of airworthiness and ensure that the aircraft can obtain satisfactory pitch force characteristics.
