Problems solved by technology

[0022] On the one hand, it is particularly disadvantageous to understand that this double unlocking, whose disconnection of the movable cascade is complicated by the restriction of access to the disconnection system, and, on the other hand, increases the nacelle's weight; finally, this double unlocking system also increases the size of the nacelle and associated cowling

Embodiment Construction

[0041] refer to figure 1 , which represents a nacelle 1 of a turbojet engine (not shown), placed in a maintenance configuration with an outer cowl 2 realized with two half-cowls 3 connected to the upper part 4 of the nacelle, which is not represented in In the accompanying drawings, it is intended to function as a connection interface with the engine pylon.

[0042] In this figure it can be seen that it is in fact a nacelle 1 of D-shaped construction type, thus having two half-cowls 3 hinged on its upper part by means of hinges 5 and comprising at their lower ends 6 for attaching said half-cowls 3 Devices that lock together / unlock.

[0043] The downstream frame can perform a translational movement backwards by means of the first drive 8 connected thereto.

[0044] The housing 2 is capable of a rearward translational movement, and also when said housing 2 is unlocked, second drive means 9 enable rotational displacement of each half housing 3 .

[0045] in the figure 1 The f...

Abstract

The present invention relates to a turbojet engine nacelle thrust reverser and to a nacelle equipped with at least one thrust reverser as aforementioned, said thrust reverser comprising: - at least one outer cowl (2), produced as two half-cowls (3) articulated on hinges (5), capable of translational movement from a position referred to as the closed position into at least one position referred to as open, - first actuating means (8) for actuating the translational movement of the downstream frame (18), - second actuating means (9) for actuating the rotation of each half-cowl (3), - locking / unlocking means (7) that lock / unlock the half-cowls (3) relative to one another, - thrust reversal means (13) comprising at least cascades of deflection veins (14) supported at their upstream end (15) by an upstream frame (16) and at their downstream end (17) by a downstream frame (18) and enclosed in a shroud (19) formed by a fan casing (20) and a fan cowl (11), means (21) of connection between the downstream frame (18) and the external cowl (2).

Description

technical field [0001] The invention relates to a thrust reverser for a turbojet engine nacelle, and to a turbojet aircraft engine incorporating a thrust reverser according to the invention. Background technique [0002] In a multi-engine aircraft, each engine is housed in a nacelle that functions both as a support and a cowl for the engine. [0003] Typically, the nacelle is connected directly or via a pylon to the wing or fuselage of the aircraft. [0004] In addition to housing the turbojet engine, said nacelle can house various additional mechanical systems, and in particular mechanical systems for driving said thrust reversers. [0005] The thrust reverser is a device capable of directing the airflow generated by the turbojet engine forward, allowing a shorter landing distance and limiting the application of the lander's brakes. [0006] In general, the nacelle has a substantially tubular structure with the upstream air intake of the turbojet, followed by a mid-sectio...
