Abstract
A thrust reverser for a turbofan-type turbojet engine is disclosed having first and second thrust reverser doors pivotably attached to the turbojet housing. The outer door is pivotably attached to the housing so as to pivot about a fixed axis extending generally transversely to the longitudinal axis of the housing. The inner thrust reverser door pivots about a second axis, extending generally parallel to the first pivot axis, which axis is also capable of moving along a translational path in a direction generally parallel to the longitudinal axis. An actuator is connected to both the inner and outer thrust reverser doors such that they are simutaneously moved between their closed and opened positions. The inner thrust reverser door pivots abouts its pivot axis as it is being moved to its open position as the pivot moves along a translational path from one end of the path to the other end. When fully opened, the inner thrust reverser door acts as a blocker panel to block off the cold-flow air duct and to direct the air laterally through an opening in the housing. A cascade structure located across the opening has a plurality of vanes to direct the air forwardly, thereby providing a thrust reversing force.
