Abstract
A system for deploying a blocker door of a nacelle includes a master link configured to be coupled to a fixed structure of the nacelle and a master crank pivotally attached to the master link. The system further includes a first door crank and a first door link pivotally coupled to the first door crank. The system further includes a first blocker door coupled to the first door link and a first driveshaft coupled to the master crank and to the first door crank and configured to transfer motion from the master crank to the first door crank such that aft translation of a translating sleeve of the nacelle drives the master crank via the master link, which drives the first door link via the first driveshaft and the first door crank to move the first blocker door into a bypass air duct defined by the nacelle.

A system for deploying a blocker door of a nacelle, comprising:
- a master link configured to be coupled to a fixed structure of the nacelle;
- a master crank pivotally attached to the master link;
- a first door crank;
- a first door link pivotally coupled to the first door crank;
- a first blocker door coupled to the first door link;
- and
- a first driveshaft coupled to the master crank and to the first door crank and configured to transfer motion from the master crank to the first door crank such that translation of a translating sleeve of the nacelle in an aft direction drives the master crank via the master link, which in turn drives the first door link via the first driveshaft and the first door crank to move the first blocker door into a bypass air duct defined by the nacelle.
A system for deploying a blocker door of a nacelle comprising:
- a master link configured to be coupled to a fixed structure of the nacelle;
- a master crank pivotally attached to the master link;
- a first door crank and a second door crank;
- a first door link pivotally coupled to the first door crank and a second door link pivotally coupled to the second door crank;
- a first blocker door coupled to the first door link and a second blocker door coupled to the second door link;
- and
- a first driveshaft coupled to the master crank and to the first door crank and a second driveshaft coupled to the master crank and to the second door crank, the first driveshaft and the second driveshaft being configured to transfer motion from the master crank to the first door crank and the second door crank, respectively, such that translation of a translating sleeve of the nacelle in an aft direction drives the master crank via the master link, which in turn drives the first door link via the first driveshaft and the first door crank and drives the second door link via the second driveshaft and the second door crank to move the first blocker door and the second blocker door into a bypass air duct defined by the nacelle.
