Abstract

A gas turbine engine assembly has a pylon with a first side and a second side. A first rail is mounted to the first side and a second rail is mounted to the second side. The assembly also has a thrust reverser with a first door assembly with a first upper portion and a first lower portion, and a second door assembly with a second upper portion and a second lower portion. A plurality of fasteners is part of the assembly. The first upper portion is connected with at least one of the plurality of fasteners to the first rail, and the second upper portion is connected with at least one of the plurality of fasteners to the second rail such that the thrust reverser is positionable between an engaged position and a disengaged position.

First claim

1 . A thrust reverser comprising:
a plurality of door assemblies variable between a first position and a second position, each of the plurality of door assemblies including an actuator, cascade vanes, and a translating outer door; a respective plurality of tracks; a plurality of attachment components connecting the plurality of door assemblies to the plurality of tracks, wherein the attachment components are capable of sliding within the track to move the plurality of door assemblies between the first position and the second position.

2 . The thrust reverser of claim 1 further comprising:
an actuator connected between the plurality of door assemblies.

3 . The thrust reverser of claim 1 further comprising:
a hinge between the plurality of door assemblies.

4 . The thrust reverser of claim 1 further comprising:
a retractable bracket that secures the plurality of door assemblies with respect to one another in the second position.

5 . The thrust reverser of claim 1 wherein each of the plurality of door assemblies contains turning vane cascades.

6 . The thrust reverser of claim 1 wherein each of the plurality of attachment components include:
a first portion within the track;
a second portion; and
a third portion attached to one of the plurality of door assemblies.

7 . A gas turbine engine assembly comprising:
a pylon with a first side and a second side; a first rail mounted to the first side and a second rail mounted to the second side; a thrust reverser including:
a first door assembly with a first upper portion and a first lower portion;
a second door assembly with a second upper portion and a second lower portion; and
a plurality of fasteners; wherein the first upper portion is connected with at least one of the plurality of fasteners to the first rail, and the second upper portion is connected with at least one of the plurality of fasteners to the second rail such that the thrust reverser is positionable between an engaged position and a disengaged position.

8 . The gas turbine engine assembly of claim 7 further comprising:
an actuator connected between the first door assembly and the second door assembly.

9 . The gas turbine engine assembly of claim 7 further comprising:
a hinge mechanism connecting the first lower portion and the second lower portion.

10 . The gas turbine engine assembly of claim 7 further comprising:
a hasp securing the first door assembly and the second door assembly.

11 . The gas turbine engine assembly of claim 10 further comprising:
a bracket pivotally connected to the first lower portion, wherein the bracket contains an engagement end that secures the first lower portion with respect to the second lower portion when the thrust reverser is in the disengaged position.

12 . The gas turbine engine assembly of claim 7 wherein the thrust reverser further comprises turning vane cascades.

13 . The gas turbine engine assembly of claim 7 wherein the first door assembly is C-shaped.

14 . The gas turbine engine assembly of claim 13 wherein the first door assembly is a mirror image of the second door assembly.

15 . The gas turbine engine of claim 7 wherein the plurality of fasteners each include:
a slidable portion within the track;
a extending portion connected to the first slidable portion; and
a pivoting portion attached to the second extending portion, wherein the third pivoting portion is secured to one of the first or second door assemblies.
