ABSTRACT:
A thrust reverser for a fan jet engine. The engine has a primary nozzle for the rearward passage of primary gases and a fan associated therewith. An aerodynamically streamlined cowl surrounds the fan and is spaced from the primary nozzle. Space therebetween forming a fan nozzle for the passage of fan gases. The cowl has a fixed forward section and a translatable aft portion. Stowed the aft section abuts the forward section and forms a continuous inner and outer flow surface and when translated rearward to a deployed position an opening is formed between the sections. A pair of blocker doors are each rotatably connected to the forward cowl section through a pair of longitudinally translatable pivots. The pivots are normally biased in a forward position by a biasing spring. Links are pivotably attached between the blocker doors and the aft cowl section. When the after section is translated aft the links allow the pivots to travel rearward under the influence of the spring and then rotate the blocker doors into the gas streams for redirecting the flow of the gas streams through the opening. When the aft cowl section returns to its forward stowed position the pivots translate forward against the spring bias by the link action until they reach the forwardmost position then the blocker doors are rotated out of the gas streams. Actuators are provided for translating the aft cowl section.
