Embodiment Construction

[0037] Such as figure 1 As shown, the nacelle 1 according to the invention has a substantially tubular shape along the longitudinal axis Δ. The nacelle 1 of the invention comprises an upstream section 2 with an air inlet lip 13 forming an air inlet 3 , an intermediate section 4 surrounding a fan 5 of a turbojet engine 6 and a downstream section 7 . The downstream section 7 comprises an inner structure 8 (commonly referred to as IFS) surrounding the upstream part of the turbojet 6 and an outer structure 9 (OFS) supporting a movable cowl (not shown) including thrust reversal means.

[0038] IFS8 and OFS9 define an annular flow path 10 that allows the passage of an airflow 12 penetrating the nacelle 1 at the air intake 3 .

[0039]The nacelle 1 of the invention ends with an injection nozzle 21 comprising an outer module 22 and an inner module 24 . This inner module 24 and outer module 22 define channels for the hot gas flow 25 ejected from the turbojet engine 6 .

Abstract

The invention relates to a door (39) for a thrust reverser of a nacelle (1) of an aircraft, said door (39) being fitted with deflection means (43a, 43b) for deflecting the air flow and which are arranged at an upstream end of the door (39) and mounted such that they can move in a deflection plane substantially perpendicular to the plane of the door (39), each deflection means (43a, 43b) being associated at its ends (51a, 51b, 53a, 63b) with an articulation arm (61a, 61b, 63a, 63b) capable of rotating about an axis of pivoting substantially perpendicular to the deflection plane allowing said deflection means (43a, 43b) to move in a straight line in the deflection plane. The invention also relates to a thrust reverser system comprising at least one such door and to a nacelle for a turbojet engine.

Description

technical field [0001] The invention relates to a door for a thrust reverser of an aircraft nacelle, which can be pivotally mounted on a fixed structure of the nacelle, said door comprising an inner surface and an outer surface, said inner surface being designed as Integrated into the annular flow path of the air flow, and said outer surface is designed to ensure external aerodynamic continuity of the nacelle equipped with thrust reversers. [0002] The invention also relates to a thrust reversal system comprising at least one such door, and to a nacelle for a turbojet engine. Background technique [0003] The aircraft is propelled by a number of turbojet engines housed in a nacelle which also houses a set of auxiliary actuating devices related to its operation which ensure various functions when the turbojet engines are running or stopped . These auxiliary actuation devices include, inter alia, thrust-reversing mechanical actuation systems. [0004] The nacelle generally...
