HIDDEN LINK SYSTEM BLOCKER DOOR

A system for deploying a blocker door of a nacelle includes a master link (306) configured to be coupled to a fixed structure (400) of the nacelle and a master crank (308) pivotally attached to the master link (306). The system further includes a first door crank (314) and a first door link (310) pivotally coupled to the first door crank (314). The system further includes a first blocker door (302) coupled to the first door link (310) and a first driveshaft (318) coupled to the master crank (308) and to the first door crank (314) and configured to transfer motion from the master crank (308) to the first door crank (314) such that aft translation of a translating sleeve (230) of the nacelle drives the master crank (308) via the master link (306), which drives the first door link (310) via the first driveshaft (318) and the first door crank (314) to move the first blocker door (302) into a bypass air duct defined by the nacelle.
