在80年代末,按美国海军武器中心的合同要求,液压研究公司在F/A-18原副翼舵机基础上研制了F/A-18副翼复合材料舵机。该舵机具有容弹击能力,满足了美国海军的格斗生存力要求。舵机克服弹丸击穿引起的活塞卡死所需的开启力比常规金属舵机小73％,同时大大减轻了重量。发展背景根据飞行安全性要求,关键飞行操纵面的液压舵机至少应为二余度,由两个独立的液压源供压。一般采用双腔舵机或两个并列的舵机。由于二余度舵机的活塞杆在机械上连成一体,在可靠性设计中,活塞或活塞杆卡死是单点
In the late 1980s, the hydraulic research company developed the F / A-18 aileron composite steering gear on the basis of the F / A-18 original aileron steering gear, as required by the contract of the U.S. Naval Weapon Center. The steering gear has a capacity of bullet-proof, to meet the requirements of the United States Navy’s combat vitality. The opening force required by the steering gear to overcome the piston jam caused by the projectile breakdown is 73% smaller than that of the conventional metal steering gear while greatly reducing the weight. Development background According to flight safety requirements, the key flight control surface of the hydraulic servo should be at least two degrees, by two independent hydraulic pressure supply. The general use of dual-lumen servo or two side-by-side steering gear. As the two redundant servo gear rod in the machinery as a whole, in the reliability of the design, the piston or piston rod stuck is a single point
