A thrust reverser assembly, comprising:
- a cascade of vanes;
- a sleeve configured to translate relative to the cascade of vanes, the sleeve including an inner sleeve portion and an outer sleeve portion;
- a first track coupled to a radially outward surface of the inner sleeve portion, the first track defining a first aperture;
- a second track coupled to the radially outward surface of the inner sleeve portion and defining a second aperture, wherein the second track is circumferentially adjacent to the first track, and wherein the first track is parallel to the second track;
- a first blocker door located between the inner sleeve portion and the outer sleeve portion, the first blocker door including a first pin located through the first aperture of the first track and a second pin located through the second aperture, wherein the first blocker door includes a first axial end and a second axial end opposite the first axial end, and wherein the second axial end is hingedly coupled to an aft ring of the cascade of vanes, and wherein the first axial end is configured to translate in a radially inward direction in response to aftward translation of the sleeve;
- a third track coupled to the radially outward surface of the inner sleeve portion, wherein the third track is circumferentially adjacent to the first track and defines a third aperture, and wherein the first track is nonparallel to the third track;
- and
- a second blocker door circumferentially adjacent to the first blocker door and slidably coupled to the third track.
