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.
Claims15
A thrust reverser assembly comprising:
- an aft cascade ring comprising an aperture;
- a thrust reverser actuation system (“TRAS”) actuator extending through the aperture;
- a retainer coupled to the aft cascade ring;
- and
- a damper coupled to the retainer, wherein the damper is in contact with the TRAS actuator, wherein the damper is configured to damp vibrations of the TRAS actuator.
A thrust reverser assembly for an aircraft comprising:
- a cascade comprising an aft cascade ring;
- a thrust reverser actuation system (“TRAS”) actuator extending through the aft cascade ring;
- and
- a flexible damper circumscribing the TRAS actuator, wherein the flexible damper is configured to exert a small reaction force on the TRAS actuator in response to a small deflection of the TRAS actuator, and wherein the flexible damper is configured to exert a large reaction force on the TRAS actuator in response to the flexible damper bottoming out.
