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 rear suspension (10) for an aircraft engine assembly comprises a structure comprising two three-point shackles (12, 12′) and one two-point shackle (14). One of the hinge pins in waiting on the two-point shackle (14), preferably the hinge pin (26) fixed to the engine yoke joint, is mounted with clearance and with a damping ring acting as a spring to prevent vibrations of the engines as long as the hinge pin (26) is not engaged. Each of the suspension connecting pins (10) is a ball joint connection, the beam (16) of the suspension (10) being provided with five aligned orifices (24, 24a, 28, 24′, 24a′).
摘要:
An arrangement configured to connect an evener bar onto a rigid structure of an aircraft engine mount, including a pin system slidingly mounted in a first passageway of a bracket to permit its displacement along a first longitudinal axis, in a first direction from a normal extended position to a retracted position in which the pin system is retracted within this same bracket, and conversely. The arrangement also includes a pin extending member carried by the system and configured to be moved parallel to the longitudinal axis, in a second direction from a normal retracted position to an extended position in which the pin extending member is joined to the system and projects beyond the system, and conversely.

A nut system including a nut including a main thread with pitch p1 and arranged along a screwing axis of the nut. A threaded device is coupled in rotation with the nut, the threaded device including a secondary non-screwed thread on the main thread from which it is separated, the secondary thread being arranged along the screwing axis and having a pitch p2 different from p1. Such a nut system may find application with a device for resistance of thrusts generated by an aircraft engine.

The present invention relates to a mounting device for an aircraft engine comprising a rigid structure and means for mounting the engine on the rigid structure, the mounting means comprising a thrust load recovery device (14) comprising two lateral thrust load recovery rods (26) each having a rear end (26b) mounted on a crossbar (28) of the device (14), by means of a first mechanical connection (44). At the rear end of each of the two rods, there is also provided a second mechanical connection (46) with play between the rear end (26b) and a support fitting (60) integral with the rigid structure. According to the invention, the first mechanical connection (44) is implemented using a pin (48) provided on the crossbar, passing through an orifice (50) provided in the rear end of the rod (26).

The present invention relates to a take-up device for thrust forces (14) for an aircraft engine attachment pylon (4), comprising a first fitting (194) attached to a rigid structure (108) of the attachment pylon, and two lateral connecting rods (14a) for take-up of thrust forces. It also comprises an axis system (190) bearing three first ball joint organs (192a, 196a) arranged along the latter and belonging respectively to a primary ball joint (192) and two secondary ball joints (196) arranged on either side of the primary ball joint, the first fitting (194) integrating a second ball joint organ (192b) cooperating with the first organ (192a) of the primary ball joint (192), and an end of each of the two connecting rods (14a) integrating a second ball joint organ (196b) cooperating respectively with the first organs (196a) of the two secondary ball joints (196).
摘要:
An engine attachment pylon for an aircraft including an aft engine attachment fitted with an aft attachment body and a first shear pin capable of resisting forces applied along a transverse direction of the pylon. The first pin passes through a lower spar of a rigid structure of the pylon and includes a lower end housed in the aft attachment body. The lower end includes a reaming through which a first pin passes, that also passes through the aft attachment body.

The invention relates to a nut system (100) comprising a nut (104) provided with a main thread (106) with pitch p1 and arranged along a screwing axis (108) of the nut. According to the invention, it also comprises a threaded device (116) coupled in rotation with the nut, this threaded device comprising a secondary non-screwed thread (122) on the main thread (106) from which it is separated, the secondary thread being arranged along the screwing axis and having a pitch p2 different from p1. Application of the invention with a device for resistance of thrusts generated by an aircraft engine.
