Abstract
A thrust reverser assembly may comprise a cascade of vanes and a sleeve configured to translate relative to the cascade of vanes. The sleeve may include an inner sleeve portion, an outer sleeve portion, and a pressure sleeve portion. The pressure sleeve portion may be located radially inward of the outer sleeve portion and may extend forward from the inner sleeve portion. A blocker door may be hingedly coupled to the pressure sleeve portion. A drag link may be pivotably coupled to the blocker door. A forward end of the drag link may be configured to deploy radially inward in response to aft translation of the sleeve.

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, an outer sleeve portion, and a pressure sleeve portion, the pressure sleeve portion being located radially inward of the outer sleeve portion and extending forward from the inner sleeve portion;
- a blocker door hingedly coupled to the pressure sleeve portion;
- and
- a drag link pivotably coupled to the blocker door, wherein a forward end of the drag link is configured to deploy radially inward in response to aft translation of the sleeve.
A nacelle, comprising:
- an inner fixed structure;
- and
- a thrust reverser assembly radially outward of the inner fixed structure, the thrust reverser assembly comprising:
- a sleeve configured to translate relative to the inner fixed structure, the sleeve including an inner sleeve portion, an outer sleeve portion, and a pressure sleeve portion, the pressure sleeve portion being located radially inward of the outer sleeve portion and extending forward from the inner sleeve portion;
- a blocker door hingedly coupled to the pressure sleeve portion;
- and
- a drag link pivotably coupled to the blocker door, wherein a forward end of the drag link is configured to deploy toward the inner fixed structure in response to aft translation of the sleeve.
A deployable drag link for a thrust reverser assembly, comprising:
- a drag link having a forward end and an aft end;
- wherein
- the drag link is rotatable about a pivot joint;
- and wherein
- the forward end of the drag link is configured to translate radially inward as the thrust reverser assembly translates into a reverse thrust position.
