某型机助力器承载特性分析

某旋翼系统装于某型直升机,实测了该直升机在悬停、盘旋、平飞、过载、机动飞行科目下的桨叶变距拉杆的铰链力矩,据此计算了该型机纵向和横向操纵助力器所受载荷;同时根据该机操纵助力器输出力与操纵速度特性曲线,考核验证某旋翼系统的铰链力矩、某型机操纵助力器的承载特性即桨叶和助力器的设计及其匹配是否合理、安全可行。

THE LOAD CHARACTERISTIC ANALYSIS OF THE ACTUATORS ON SOME TYPE HELICOPTER

Some type rotor system is equipped on some type helicopter. The hinge moments of pitch links are measured while the helicopter is hovering, turning,level flight,over load and flexible flight. By the hinge moments, the loads of the longitudinal actuator and the lateral actuators are calculated in this paper. Then, with the actuators output load and speed characteristic, evaluate the rationality and security of the design and matching of rotor system and rotor control system actuators.
