Abstract:
The present invention relates to a jet engine nacelle (1), of the type comprising an aft section forming an external structure (2) which, together with a concentric internal structure (4) comprising an internal panel (10) intended to surround a down-stream portion of the jet engine, defines an annular flow duct for a so-called secondary stream (3), characterized in that exhaust means (11) are formed in the internal panel such that any unwanted excess pressure is discharged into the annular duct.
Abstract:
Disclosed is a coupling device (1) intended to connect first and second elements which are articulated with respect to one another, wherein the device includes a compression element (2) designed to allow a compressive force to pass from one element to another in a first state, and a tension element (3) designed to allow a tensile force to pass from one element to another in a second state, the compression element additionally forming a substitution tension element designed to allow a tensile force to pass from one element to another in a third state corresponding to the fracturing of the tension element.
Abstract:
An actuating device is provided for a locking system which locks one of half-shells of a jet engine nacelle with respect to the other half-shell. The actuating device includes a fixed body in which an actuating rod is translationally and rotationally mounted with respect to the rod's longitudinal axis, and the fixed body has a track cooperating with a follower projecting from the actuating rod. In particular, the actuating rod includes a first end equipped with a handle and a second end connected to the locking system. The track has a middle part running parallel to the longitudinal axis, a first end part and a second end part formed on each side of the middle part, each of the end parts running perpendicular to the longitudinal axis.
Abstract:
The invention relates to a locking device (9) designed to be arranged in a junction region of a nacelle, comprising a locking system (10), intended to be mounted on a first half-shell of the nacelle, engaging with a retention member (11) intended to be mounted on a second half-shell, the locking system (10) being actuable between a locked state and an unlocked state with respect to the retention number (11), the locking system (10) and the retention member (11) being movable with respect to one another between a drawn-together position in which they can be locked with respect to one another and a spaced-apart position. The locking system (10) and/or the retention member (11) comprise locking means (25) designed to allow the locking system (10) to be locked with respect to the retention member (11) when they are in the drawn-together position and to prevent them from being locked when they are in the spaced-apart position.
Abstract:
The invention relates to a coupling device (14) intended to connect first and second elements (4, 5) which can move relative to one another, comprising a connecting rod (16) coupled to the first and second movable elements (4, 5) at first and second ends (18, 19) respectively, at least one of the ends of the connecting rod (16) having a head (22) intended to cooperate with locking means (23) belonging to the corresponding movable element (5) so as to removably fasten the connecting rod (16) to the corresponding movable element (5), characterized in that the coupling device (14, 15) comprises at least one telescopic guide member (25) serving to support and guide the connecting rod (16) during the movement of the movable elements (4, 5), having first and second ends (28, 26) intended to be attached to first and second support elements (23, 16) respectively.
Abstract:
The invention relates to a nacelle for a turbojet engine, comprising a rear section forming an outer structure which defines, together with a concentric inner structure (4) comprising an inner panel (10) for surrounding a downstream part of the turbojet engine, an annular flow channel for a so-called secondary flow. The invention is characterized in that the exhaust means (11) are arranged in the inner panel in such a way that any inopportune surge is exhausted in the annular channel.

The locking system (10) and/or the retention member (11) comprise locking means (25) designed to allow the locking system (10) to be locked with respect to the retention member (11) when they are in the drawn-together position and to prevent them from being locked when they are in the spaced-apart position.
Abstract:
The invention relates to a locking device (11) comprising at least one locking system (13) having at least one locking member (17) that can be actuated by linking means (28), the linking means being able to be moved over a defined travel, the movement of the locking means (28) over a first part of the travel enabling the locking member (17) to be actuated, alternately between an unlocked position of the locking member (17) and a locked position thereof, characterized in that the locking system (13) is designed so that the locking member (17) remains immobile during the movement of the linking means (28) over a second portion of the travel, with a view to compensating for the adjustment of the connecting means (28) and also any malpositioning of the locking system (13).

Abstract:
The invention relates to a locking device (5, 6) comprising a first locking system (7) equipped with a control handle (12), intended to be actuated by an operator, characterized in that it includes a second locking system (8) connected to the first (7) by linking means (9) designed to actuate the second locking system (8) because of the actuation of the first (7), the first locking system (7) being actuated alternately between a locked state and an unlocked state by movement of the handle (12) over the totality of a defined course, the linking means (9) having sequencing means designed to actuate the second locking system (8), between a locked state and an unlocked state thereof respectively, during the displacement of the handle (12) over only part of the travel of the latter.
