초록 ▼

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.

A thrust reverser for a turbojet engine having a housing extending along a longitudinal axis and defining at least one generally laterally facing opening, an upstream outer housing surface and an upstream inner housing surface located upstream of the generally laterally facing opening, and a downstream outer housing surface and a downstream inner housing surface located downstream of the generally laterally facing opening, the upstream and downstream inner housing surfaces defining a boundary of a gas flow stream, the thrust reverser comprising: a) a first thrust reverser door; b) first means pivotally attaching the first thrust reverser door to the housing so as to pivot about a fixed, first axis between a closed forward thrust position wherein the first thrust reverser door covers the generally laterally facing opening, and an open, reverse thrust position wherein the first thrust reverser door uncovers the generally laterally facing opening; c) a second thrust reverser door located radially inwardly of the first thrust reverser door in a direction toward the longitudinal axis; d) second means pivotally attaching the second thrust reverser door to the housing so as to pivot about a second axis extending generally parallel to the first axis, the second means enabling the second axis to move along a translational path such that the second thrust reverser door is movable between a first forward thrust position wherein the second axis is located at one end of the translational path and the second thrust reverser extends generally parallel to the gas flow stream, and a second, reverse thrust position wherein the second axis is located at an opposite end of the translational path and the second thrust reverser door deflects at least a portion of the gas flow stream toward the generally laterally facing opening; e) actuator means; f) linkage means connecting the actuator means with the first and second thrust reverser doors such that the actuator means pivots the first and second thrust reverser doors in the same direction about their respective axes between their closed and open positions; and, g) a cascade structure extending substantially over the generally laterally facing opening so as to direct the gas flow passing through the opening in a generally forward direction.
