Abstract
A nacelle may comprise a thrust reverser. The thrust reverser may comprise a translating sleeve, a cascade array, and a TRAS actuator. The TRAS actuator may pass through an aperture in an aft cascade ring of the cascade array. A retainer may be coupled to the aft cascade ring. A damper may be coupled to the retainer. The damper may circumscribe the TRAS actuator. The damper may be configured to damp vibrations in the TRAS actuator. As an amplitude of vibration or deflection of the TRAS actuator increases, a reaction force applied by the damper on the TRAS actuator increases, which prevents the TRAS actuator from contacting the aft cascade ring.
