Abstract
A thrust reverser system is provided that includes a sleeve, a fixed cascade structure and a blocker door. The fixed cascade structure is within a cavity of the sleeve when the sleeve is in a sleeve stowed position. The blocker door is within the cavity of the sleeve when the sleeve is in the sleeve stowed position and the blocker door is in a blocker door stowed position. The blocker door projects in a radial inward direction away from the sleeve towards the centerline when the sleeve is in a sleeve deployed position and when the blocker door is in a blocker door deployed position. The blocker door includes a pivot attachment fixed at an end of the blocker door. The pivot attachment is configured to move in a forward direction from a first location to a second location.
Claims7
An assembly for an aircraft propulsion system, comprising:
- a thrust reverser system including a sleeve, a fixed cascade structure and a blocker door;
- the sleeve configured to translate in an aft direction along a centerline from a sleeve stowed position to a sleeve deployed position;
- the fixed cascade structure disposed within a cavity of the sleeve when the sleeve is in the sleeve stowed position;
- the blocker door configured to move between a blocker door stowed position and a blocker door deployed position, the blocker door disposed within the cavity of the sleeve when the sleeve is in the sleeve stowed position and the blocker door is in the blocker door stowed position, and the blocker door projecting in a radial inward direction away from the sleeve towards the centerline when the sleeve is in the sleeve deployed position and the blocker door is in the blocker door deployed position;
- the blocker door comprising a pivot attachment fixed at an end of the blocker door, the pivot attachment configured to move in a forward direction from a first location to a second location;
- a fixed structure comprising a frame track;
- and
- a frame extending circumferentially about the centerline to a frame side, the frame comprising a frame slider at the frame side, and the frame slider configured to translate along the frame track as the blocker door moves towards and away from the blocker door deployed position;
- the pivot attachment pivotally attaching the blocker door to the frame;
- and
- the thrust reverser system further including
- a fixed guide comprising a first lateral track and an axial track;
- a first lateral track slider configured to translate, laterally relative to the centerline, along the first lateral track;
- an axial track slider configured to translate, axially along the centerline, along the axial track, and the axial track slider coupled to the frame;
- a latch configured to selectively mate with the sleeve;
- a first forward link extending between and pivotally connected to the first lateral track slider and the axial track slider;
- and
- a first aft link extending between and pivotally connected to the first lateral track slider and the latch.
