ABSTRACT:
An improved deployment mechanism for deploying blocker doors between a stowed and a deployed position. At least a pair of operable blocker doors are utilized. These doors are pivotally attached to fixed cowl structure surrounding a turbo fan engine. A yoke member having adjacent curvilinear tracks is carried by a rear translatable cowl section. Sliders are provided that follow the adjacent tracks. A drag link is connected between a slider and fixed aircraft structure and a door deploying link is connected between each blocker door and is associated slider. In a second configuration, more than one blocker door is actuated by a link connected to a single slider, coupled by more than one door deploying link. When the translatable cowl section is translated rearward by conventional actuation, a peripheral outflow passage is formed between the cowl sections and the blocker doors now being deployed redirect the fan air through the peripheral opening.
