    • A flight control actuation system comprises a controller, electromechanical actuator and a pneumatic actuator. During normal operation, only the electromechanical actuator is needed to operate a flight control surface. When the electromechanical actuator load level exceeds 40 amps positive, the controller activates the pneumatic actuator to offset electromechanical actuator loads to assist the manipulation of flight control surfaces. The assistance from the pneumatic load assist actuator enables the use of an electromechanical actuator that is smaller in size and mass, requires less power, needs less cooling processes, achieves high output forces and adapts to electrical current variations. The flight control actuation system is adapted for aircraft, spacecraft, missiles, and other flight vehicles, especially flight vehicles that are large in size and travel at high velocities.
    • 飞行控制致动系统包括控制器,机电致动器和气动致动器。 在正常操作期间,仅需要机电致动器来操作飞行控制表面。 当机电致动器负载水平超过40安培正时,控制器激活气动执行器以抵消机电执行器负载,以帮助操纵飞行控制表面。 来自气动负载辅助致动器的帮助使得能够使用尺寸和质量更小的机电致动器,需要更少的功率,更少的冷却过程,实现高输出力并适应于电流变化。 飞行控制致动系统适用于飞机,航天器,导弹和其他飞行器,特别是大型飞行器和高速行驶的飞行器。
