Abstract
A thrust reverser pivot door may comprise a support structure configured to pivot between a stowed position and a deployed position, and a pivot door outer skin coupled to the support structure, wherein a forward lip of the pivot door outer skin is configured to extend forward of a torque box and overlap the fan case to advantageously increase the overall size or area of the pivot door.
Claims9
A thrust reverser for a nacelle comprising a fan cowl configured to surround a fan case, the thrust reverser comprising:
- an inner fixed structure;
- an outer fixed structure comprising a thrust reverser outer skin;
- a bypass duct disposed between the inner fixed structure and the outer fixed structure;
- a torque box disposed at a forward end of the thrust reverser;
- a support ring disposed forward of the torque box, wherein the support ring is axially spaced apart from the torque box;
- a bracket configured to be coupled to the fan case independent of the torque box, wherein the support ring is configured to be supported by the bracket;
- and
- a pivot door mounted on the outer fixed structure for pivotal movement with respect to the outer fixed structure between a stowed and a deployed position, the pivot door comprising:
- a support structure;
- and
- a pivot door outer skin coupled to the support structure;
- wherein a forward lip of the pivot door outer skin is configured to extend forward of a forwardmost end of the torque box when the thrust reverser pivot door is in a stowed position, and the forward lip is supported by the support ring when the thrust reverser pivot door is in the stowed position.
