Abstract
An assembly is provided for an aircraft propulsion system. This assembly includes a fixed structure, a translating structure and a thrust reverser. The translating structure is configured to translate between a stowed position and a deployed position. The thrust reverser includes a blocker door, an actuation linkage and a spring cartridge. The blocker door is pivotally coupled to the translating structure. The actuation linkage operatively couples the blocker door to the fixed structure. The spring cartridge is coupled to the blocker door and the translating structure. The spring cartridge is configured to bias the blocker door closed.

An assembly for an aircraft propulsion system, comprising:
- a fixed structure;
- a translating structure configured to translate between a stowed position and a deployed position;
- and
- a thrust reverser including a blocker door, an actuation linkage and a spring cartridge;
- the blocker door pivotally coupled to the translating structure;
- the actuation linkage operatively coupling the blocker door to the fixed structure, the actuation linkage including a structure link and a door link;
- the structure link including a first structure link arm, a second structure link arm, and a structure link mount connected to the first structure link arm and the second structure link arm, the first structure link arm and the second structure link arm pivotally coupled to the fixed structure, and the first structure link arm and the second structure link arm laterally converging towards one another as the first structure link arm and the second structure link arm extend longitudinally towards the structure link mount;
- the door link is between and pivotally coupled to the structure link mount and the blocker door;
- and
- the spring cartridge coupled to the blocker door and the translating structure, and the spring cartridge configured to bias the blocker door closed.
