<p>A thrust reverser blocker door assembly for a fanjet engine (34) wherein a plurality of blocker doors (10) are disposed aerodynamically about a peripheral circumferential zone of a central fan duct (46) of the engine in a cruise configuration and are pivoted radially into an annnular ring interrupting the fan duct in a thrust reversing configuration for diverting air radially outward and forward through a concentric bypass duct (48), each of the blocker doors (10) being secured for pivotal displacement by an articulated linkage (50) comprising a drag link (62) disposed for arcuate motion about a fixed pivot point (64) at its proximal end, an overcenter link (12) spanning the blocker door (10) and the distal end of the drag link (62) at a longitudinally translatable pivot point (70), and a biasing member (100) for tensioning the articulated linkage (50) and the blocker door (10) radially outward about the translatable pivot point (70) when in the cruise configuration. </p> |
