A thrust reverser nozzle for a gas turbine engine nacelle includes opposite and asymmetrically pivoting first and second doors defining a nacelle aft section, first and second trailing edges of the first and second doors adjacent to a propulsive jet nozzle outlet of the nacelle, the doors being pivotable simultaneously between a stowed position and a deployed position such that the first trailing edge is positioned behind the second trailing edge when the doors are in the deployed position, and the first and second fairings attached to the first and second doors in relative fixed positions to the first and second doors respectively. Male contour middle portions of the first fairings may complementarily match female contour middle portions of the second fairings and are received within the female contour middle portion when the doors are in the stowed position. The fairings may be removably attached to the doors.

1. A thrust reverser nozzle for a gas turbine engine nacelle, the thrust reverser nozzle comprising: opposite and asymmetrically pivoting first and second doors defining an aft section of the nacelle,the first and second doors including first and second trailing edges respectively adjacent to a nozzle outlet of the nacelle,the first and second doors being pivotable simultaneously between a stowed position and a deployed position,the first trailing edge of the first door being positioned behind the second trailing edge of the second door in the deployed position,first and second fairings attached to the first and second doors in relative fixed positions to the first and second doors respectively, and having complementary adjoining contours permitting relative rotation to avoid interference as said doors are deployed open the first fairing including leading, middle, and trailing portions correspondingly adjoining leading, middle, and trailing portions of the second fairing when the doors are stowed, andthe leading portions of the first and second fairings overlapping the trailing portions of the second and first fairings, respectively, as the fairings move about the middle portions when the doors are deployed. 2. The thrust reverser nozzle as claimed in claim 1 wherein: the first fairings include male contour middle portions,the second fairings include female contour middle portions, andthe male contour middle portion complementarily matches the female contour middle portion for the male contour middle portion being received within the female contour middle portion when the first and second doors are in the stowed position. 3. The thrust reverser nozzle as claimed in claim 2, further comprising the first and second fairings being removably attached to the first and second doors respectively. 4. The thrust reverser nozzle as claimed in claim 2, further comprising a clearance between the first and second fairings for allowing initial movement between the first and second fairings during deploying and/or stowing of the first and second doors respectively. 5. The thrust reverser nozzle as claimed in claim 4, further comprising the first and second fairings having first and second geometries sized and shaped for allowing the leading portion of the second fairings to move about and over a laterally outer side of the trailing portion of the first fairings when the first and second doors are deployed from the stowed position. 6. The thrust reverser nozzle as claimed in claim 1, further comprising the first and second fairings being conical and tapering in a downstream direction. 7. The thrust reverser nozzle as claimed in claim 1, further comprising: front fairings mounted to a jet pipe disposed radially inwardly of the first and second doors,the front fairing located upstream of the first and second fairings, andan outer surface of the nacelle in the aft section including the front, first, and second fairings conically tapering in a downstream direction with the outer surface conically tapering in the downstream direction. 8. The thrust reverser nozzle as claimed in claim 7, further comprising the front fairings having a front contour portion complementarily shaped to first and second contour portions of the first and second fairings. 9. The thrust reverser nozzle as claimed in claim 7 further comprising the outer surface being aerodynamically smooth and having no bumps. 10. The thrust reverser nozzle as claimed in claim 9 wherein: the first fairings include male contour middle portions,the second fairings include female contour middle portions, andthe male contour middle portion complementarily matches the female contour middle portion for the male contour middle portion being received within the female contour middle portion when the first and second doors are in the stowed position. 11. The thrust reverser nozzle as claimed in claim 10, further comprising the first and second fairings being removably attached to the first and second doors respectively. 12. The thrust reverser nozzle as claimed in claim 10, further comprising a clearance between the first and second fairings for allowing initial movement between the first and second fairings during deploying and/or stowing of the first and second doors respectively. 13. The thrust reverser nozzle as claimed in claim 10, further comprising the first and second fairings having first and second geometries sized and shaped for allowing the portion of the second fairings to move about and over a laterally outer side of the trailing portion of the first fairings when the first and second doors are deployed from the stowed position. 14. A thrust reverser comprising: first and second reverser doors pivotally mounted at corresponding first and second hinge axes to opposite sides of a jet pipe and converging aft to a common nozzle outlet in a stowed closed position;said first door having a first fairing and said second door having an adjoining second fairing collectively covering said first and second hinge axes;said first and second fairings having complementary contours adjoining each other to scissor with forward and aft overlaps as said doors pivot open to a deployed position;said first fairing including forward, middle, and aft portions correspondingly adjoining forward, middle, and aft portions of said second fairing when said doors are stowed; andsaid forward portions of said first and second fairings overlapping said aft portions of said second and first fairings, respectively, as said fairings scissor about said middle portions when said doors are deployed. 15. A reverser according to claim 14 wherein said middle portion of said first fairing is convex, and said middle portion of said second fairing is complementarily concave for permitting unobstructed scissoring overlap of said fairings as said doors are deployed. 16. A reverser according to claim 14 wherein: said doors are pivotally mounted to said jet pipe for clamshell deployment with a trailing edge of said second door nesting inside a trailing edge of said first door when deployed; andsaid aft portion of said first fairing is disposed inside said forward portion of said second fairing while said forward portion of said first fairing is disposed outside said aft portion of said second fairing when deployed. 17. A reverser according to claim 14 wherein: said doors have outer mold line surfaces converging aft to said nozzle outlet; andsaid first and second fairings complement and conform with each other when said doors are stowed, and converge aft to conform axially and circumferentially with said outer mold line surfaces of said doors. 18. A reverser according to claim 14 wherein said jet pipe, doors, and fairings converge aft to a planar nozzle outlet, with said fairings being mounted flush with said doors when stowed for reducing wetted drag external surface area of said reverser and minimizing base area around said planar nozzle outlet. 19. A reverser according to claim 14 further comprising: an actuation system operatively joined to said doors for deploying open said doors to said deployed position and stowing closed said doors to said stowed position;a front fairing covering said actuation system and conforming flush with said doors and first and second fairings; andsaid front, first, and second fairings are removably attached to said jet pipe and doors for permitting access to said actuation system and hinges.
