摘要
YF-23A战斗机具有极大的静不安定性,在不开加力的情况下可以实现超声速巡航,其设计目标是在亚声速和超声速均具有优于对手的机动能力,上述要求使得飞行控制作动系统必须具有空前的能力和性能。其独特的飞行和机动包线要求其作动系统在低速时具有高的舵面偏转速率和大的行程,在超声速时要具有附加铰链力矩输出能力,为实现上述目标,开发出具有液压与电能守恒的作动系统。
The YF-23 A Fighter was a revolutionary statically unstable aircraft that cruised at supersonic speeds without afterburner and was designed to outmaneuver opponents at subsonic and supersonic speeds. Combining these demanded a flight control actuation system of unprecedented power and performance. Its unique flight and maneuvering envelop required high surface rate and large actuator excursion at low flight speeds, as well as the power to generate increased hinge moments at supersonic speeds. To achieve these specifications, hydraulic flow and electrical power conservation techniques was utilized.
