The invention relates to a fully differential course control coaxial helicopter control system of a single automatic inclinator, which comprises a periodic variable pitch control system and a course control system, and a course control system comprises an upper rotor course control system and a lower rotor course control system. The periodic pitch control system comprises a single automatic inclinator, a longitudinal steering engine and a transverse steering engine and can control rolling and pitching of the helicopter; the upper rotor course control system and the lower rotor course control system act at the same time to control the course of the helicopter. A single automatic inclinator and fully differential course control mode is adopted, under the condition that pitching, rolling and course control of the helicopter are achieved, compared with a coaxial unmanned helicopter adopting a conventional fully differential course control mode, the number, the size and the weight of parts are reduced, the space utilization rate of a rotor shaft is increased, the structure is compact, and the possible dynamics problem risk of the helicopter rotor shaft is reduced.
本发明涉及单自动倾斜器的全差动航向控制共轴式直升机操纵系统,包括周期变距操纵系统和航向操纵系统,其中的航向操作系统包括上旋翼航向操纵系统和下旋翼航向操纵系统。周期变距操纵系统包括单自动倾斜器、纵向舵机和横向舵机,能够实现对直升机滚转和俯仰的操控;上旋翼航向操纵系统、下旋翼航向操纵系统同时作用以实现对直升机航向的操控。本发明采用单自动倾斜器和全差动航向控制的方式,在实现直升机俯仰、滚转和航向控制的情况下,相较于常规形式全差动航向控制的共轴式无人直升机,减少零部件数量、尺寸及重量,提高旋翼轴的空间利用率,结构紧凑,减小直升机旋翼轴可能面临的动力学问题风险。
