Bi-directional no-back brake progressive modulation spring systems and methods

An apparatus comprising:

• a no-back brake, disposed within an actuator coupled to an aircraft, comprising:
• a shaft;
• a ball ramp plate, coupled to the shaft, configured to receive a force comprising an air loading force and to be displaced responsive to the force;
• a brake, coupled to the shaft and coupled to the ball ramp plate, configured to be displaced, by the ball ramp plate, corresponding to a distance the ball ramp plate is displaced;
• and
• a modulating spring, coupled to the shaft and coupled to the brake, configured to compress in response to the brake being displaced, wherein the modulating spring is configured to apply a selective compressive force at the brake corresponding to a distance the brake is displaced, and wherein the modulating spring comprises:
• a first spring;
• a first cylindrical washer oriented adjacent to the first spring;
• a second spring oriented adjacent to the first cylindrical washer;
• and
• wherein the first spring and the second spring comprise a belleville spring.
