Methods and systems according to one or more examples are provided for reducing chatter in a no-back brake during aiding load operations. In one example, an apparatus comprises a no-back brake, disposed within an actuator coupled to an aircraft, including a shaft, and a ball ramp plate, coupled to the shaft, to receive a force comprising an air loading force and is displaced responsive to the force. The apparatus further comprises a brake, coupled to the shaft and coupled to the ball ramp plate, and displaced by the ball ramp plate corresponding to a distance the ball ramp plate is displaced.The apparatus further comprises a modulating spring, coupled to the shaft and coupled to the brake, configured to compress in response to the brake being displaced, and the modulating spring is configured to apply a selective compressive force at the brake corresponding to a distance the brake is displaced.
本申请涉及双向防逆转制动器渐进式调制弹簧系统和方法。根据一个或多个示例,提供了在辅助载荷操作期间减小防逆转制动器中的颤振的方法和系统。在一个示例中,一种设备包括设置在耦接到飞机的致动器内的防逆转制动器,包括轴和耦接到轴的滚珠坡道板以接收包括空气载荷力的力并响应于该力而移位。设备进一步包括耦接到轴并耦接到滚珠坡道板的制动器,并且该制动器对应于滚珠坡道板移位的距离通过滚珠坡道板而移位。设备进一步包括耦接到轴并耦接到制动器的调制弹簧,该调制弹簧构造成响应于制动器正在移位而压缩,并且调制弹簧构造成对应于制动器移位的距离在制动器处施加选择性压缩力。
