摘要:
The invention relates to a device (131) for assembly of a shroud (26) arranged between an air intake (22) and a pylon (2) fixed to the engine (4), the device comprising: stressed flexible means (130) provided with a first end (130a) and a second end (130b); first connection means connected to the air intake and to the end (130a); and second connection means connected to the shroud and to the end (130b). According to the invention, the second connection means comprise a primary assembly (140) fixed to the shroud and a secondary assembly (142) fixed to the second end (130b), and the primary and secondary assemblies (140,142) are connected to each other through a pivot connection (144).
摘要:
A mounting structure for an aircraft engine including a rigid structure and a mechanism to mount the engine on the rigid structure. The mounting mechanism includes a thrust load device including two side thrust links each including an aft end mounted on an evener bar of the device, via a mechanical connection. Each connection is formed by a lug provided on the evener bar and passing through an orifice made in the aft end, the lug being arranged so as to extend substantially laterally relative to the mounting structure.

A device for attaching an aircraft engine including a rigid structure forming a structure box, and a device for absorbing thrust loads including a main fitting fixedly mounted on one of the spars forming the structure box, by a fixing mechanism. The fixing mechanism includes a fixing peg mounted on the spar and including a main portion located on the outside relatively to the box, the fitting being crossed by the portion of the peg and pressed against the spar by a bell-shaped supporting washer surrounding the main portion and stressed by a screw crossing it, the latter being screwed into a barrel nut housed in a bore made within the main portion.
摘要:
An engine attachment for an assembly system configured to be mounted between a rigid structure of an attachment strut of an aircraft engine and an engine. The attachment includes a main body, a rudder bar on an articulated mounting on the main body by a hinge pin, and two thrust absorption rods each with one end connected to the rudder bar. The main body includes a first main brace and a second main brace superimposed on the first brace. The hinge pin is formed by a first portion and a second portion, wherein the first portion is made in one piece with the first brace and the second portion is made in one piece with the second brace. Furthermore, the braces define a stop limit surface configured to limit rotation of the rudder bar.

A hinge device of a nacelle cowling of an aircraft engine on a supporting structure is disclosed. The hinge device includes two fittings and a link rod connected thereto and mounted on the fitting by an end connection. The link rod is further mounted on the fitting by an intermediate connection including a pivot pin slidably housed in a hole, and the end connection includes a guide pin slidably housed in a guide ramp. The connections are designed so as to create, upon rotation of the link rod about the pin, a relative movement of the axis in the ramp, simultaneously causing a relative movement of the pin in the hole.

This invention relates to a hinge device (20) of a nacelle cowling of an aircraft engine (6) on a supporting structure, including two fittings as well as a link rod (34) connected thereto and mounted on the fitting (32) by means of an end connection (48). According to the invention, the link rod is also mounted on the fitting (32) by means of an intermediate connection (56) including a pivot pin (58) slidably housed in a hole (60), and the connection (48) includes a guide pin (50) slidably housed in a guide ramp (54), and the connections (48, 56) are designed so as to create, upon rotation of the link rod about the pin (58), a relative movement of the axis (50) in the ramp (54), simultaneously causing a relative movement of the pin (58) in the hole (54).
