The thrust reverser is used with a gas turbine engine and includes first and second doors pivotable between a stowed position and a deployed position. When deployed, pivoting fairings on the first door are moved so as to give room to the second door as its trailing edge moves within the first door.

The thrust reverser is used with a gas turbine engine and includes first and second doors pivotable between a stowed position and a deployed position. When deployed, pivoting fairings on the first door are moved so as to give room to the second door as its trailing edge moves within the first door. When stowed, the second door preferably provides the locking mechanism to the pivoting fairings of the first door.

What is claimed is: 1. A thrust reverser for a nacelle of a gas turbine engine having an axis, the thrust reverser comprising a first reverser door and a second reverser door defining a portion of an aft section of the nacelle, the doors having respective trailing edges adjacent to a propulsive jet outlet of the nacelle and being pivotable simultaneously between a stowed position and a deployed position, the trailing edge of the first door being positioned behind the trailing edge of the second door in the deployed position, the thrust reverser including a pair of pivoting fairings, one fairing disposed on either side of the nacelle, the fairings disposed and extending between the doors when the doors are in the stowed position, each fairing having a respective trailing edge adjacent to the propulsive jet outlet and being pivotally connected to an axially-extending side edge of the first door, the pivoting fairings being in a stowed position when the doors are in a stowed position, and the pivoting fairings pivoting about an axis substantially parallel to the first door side edge to an outwardly pivoted position when the doors are in a deployed position. 2. The thrust reverser as defined in claim 1, wherein the first door is an upper door and the second door is a lower door. 3. The thrust reverser as defined in claim 1, wherein the trailing edges of the pivoting fairings have a substantially semi-cylindrical shape. 4. The thrust reverser as defined in claim 1, wherein the pivoting fairings are outwardly biased. 5. The thrust reverser as defined in claim 4, wherein each pivoting fairing is outwardly biased by at least one torsion spring. 6. The thrust reverser as defined in claim 1, farther comprising a locking mechanism provided for each pivoting fairing and locking the corresponding pivoting fairing in its stowed position. 7. The thrust reverser as defined in claim 6, wherein each locking mechanism includes a tab projecting from an edge of the pivoting fairing and which is held under an adjacent longitudinal side edge of the second door when the pivoting fairings and the doors are in their stowed position. 8. The thrust reverser as defined in claim 1, wherein the pivoting fairings have an angular position between their stowed position and their outwardly pivoted position that depends upon an angular position of the first door over at least a portion of a range of angular positions of the first door. 9. The thrust reverser as defined in claim 8, wherein the angular position of the pivoting fairings is at least partially dependent upon a relative position of a follower arm along an inclined ramp provided on a fixed structure. 10. The thrust reverser as defined in claim 9, wherein the fixed structure is a jet pipe to which the doors are pivotally connected. 11. A thrust reverser comprising at least two thrust reverser doors and a fairing extending between the doors when the thrust reverser doors are in a closed position, the fairing having a wall defining an outer surface and being pivotable around a pivot axis located adjacent to an edge of the wall, the wall being pivotally connected to a longitudinally-extending side edge of a said door, the pivot axis substantially parallel to said side edge, the wall being outwardly biased around the pivot axis. 12. The fairing as defined in claim 11, wherein the wall has a trailing edge having a substantially semi-cylindrical shape. 13. The fairing as defined in claim 11, further comprising at least one torsion spring provided between the door and the wall. 14. The fairing as defined in claim 11, further comprising means for locking the wall in a stowed position. 15. The fairing as defined in claim 14, wherein the means for locking comprises a tab projecting from an edge of the wall and opposite the pivot axis. 16. The fairing as defined in claim 11, wherein the wall outwardly pivots around the pivot axis when the doors are in the deployed position and has a pivot angle depending at least partially on a pivot angle of the door. 17. The fairing as defined in claim 16, wherein the pivot angle of the wall is set by a follower arm attached to the wall and engaged on a fixed inclined ramp. 18. The fairing as defined in claim 17, wherein the fixed inclined ramp is attached to a jet pipe arm. 19. A method of pivoting doors of a thrust reverser, the method comprising the simultaneous steps of: pivoting the doors from a stowed position to a deployed position in such a way that a trailing edge of a first one of the doors moves behind the trailing edge of a second one of the doors; and outwardly pivoting a pair of opposite fairings about respective pivot axes which are substantially parallel to longitudinally-extending edges defining corresponding sides of the first door and adjacent to its trailing edge so as to provide clearance for the trailing edge of the second door in the deployed position. 20. The method as defined in claim 19, further comprising the step of locking the fairings when the doors are in their stowed position using the second door.
