Embodiment Construction

[0032] now refer to figure 1 , figure 1 The right-hand half-shell 1 of the nacelle is shown, which in this case should be positioned at the rear of the nacelle and form part of a thrust reversal arrangement (it should be understood that the invention is also applicable in the case of a simple nacelle, i.e. nacelles without thrust reversers).

[0033] Reference signs AV and AR denote respectively the front and the rear of the half-shell 1 with respect to the flow direction of the air that should flow inside the half-shell 1 .

[0034] In this particular case, the half-shell 1 comprises an inner half-structure 3 delimiting a half-cavity C intended to house a jet engine (not shown).

[0035] The half-shell 1 also comprises an outer structure 5 which, together with the inner structure 3, defines a half-flow path V through which the flow of cold air flowing between the front and the rear of the half-shell 1 will travel.

[0036] In its upper part, that is to say in its part that...

Abstract

Coupling device for connecting the two half-shells (1') of an aircraft engine nacelle, comprising a connecting rod (17) which can be mounted in an articulated manner on one (1') of the two half-shells, a retention member for this connecting rod (17) that can be mounted on the other half-shell, and means designed to allow limited movements of said connecting rod with respect to said retention member.

Description

technical field [0001] The invention relates to a coupling device for connecting two half shells of an aircraft engine nacelle and to a nacelle equipped with such a device. Background technique [0002] As is well known, an aircraft nacelle is a structure which surrounds the engine and in particular directs air towards it. [0003] Nacelles such as these generally comprise at least two half-shells hingedly mounted on pylons about an axis substantially parallel to the axis of the nacelle. [0004] The pylon itself should be fixed under the wing of the aircraft. [0005] Hinging the two half-shells to the pylon allows the half-shells to be opened upwards to provide access to the engine for maintenance operations. [0006] During flight, these two half-shells are subjected to significant stresses mainly due to the pressure generated by the flow of air over these half-shells. [0007] The coupling means connecting the two half-shells constitutes a bridge over which, inter ali...
