  • Publication number: 20120080555
    Abstract: 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.

  • Patent number: 8087608
    Abstract: 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.

  • Patent number: 7607609
    Abstract: A mounting device for an aircraft engine includes a rigid structure and a device for mounting the engine on the rigid structure, the mounting device including a thrust load recovery device with two lateral thrust load recovery rods each having a rear end mounted on a crossbar of the recovery device with a first mechanical connection. At the rear end of each of the two rods, there is also provided a second mechanical connection with play between the rear end and a support fitting integral with the rigid structure. The first mechanical connection is implemented using a pin provided on the crossbar, passing through an orifice provided in the rear end of the rod.

  • Publication number: 20090200419
    Abstract: 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.

  • Patent number: 6682015
    Abstract: A device attaches an engine to an aircraft. The device (10) is inserted between the engine (14) and a pylon (12) designed to be attached to an aircraft structure, such as a wing or fuselage section. The attachment device (10) generally includes two brackets (18a, 18b) joined together and secured to the pylon (12) and two pairs of rods (20a, 20b, 22a, 22b) inserted between the two brackets (18a, 18b) and a part (24) of the structure of the engine (14). Thus the integrity of the link between the pylon (12) and the engine (14) is preserved in the event of failure of any of the parts which constitute the device, without there being any need for a backup attachment system.

  • Patent number: 6648271
    Abstract: A device for recovering forces generated by an aircraft engine has an engine strut (10), capable of being fixed to a wing or a fuselage of an aircraft, and an attachment device (12) fixed to the engine strut (10) and on which the engine is mounted. An intermediate fitting (24) of large dimensions, capable of recovering exceptionally high forces is fixed to several strut fittings (30) independent from each other, for example by bolts (28), across a lower spar (14) of the engine strut (10).

  • Patent number: 6494403
    Abstract: Device for aircraft thrust reovery capable of linking a turboshaft engine and an engine strut. A device for thrust recovery (16) linking a turboshaft engine to an aircraft engine strut comprising an attachment fitting (22) fixed to an engine strut, a control bar (38) articulated on the attachment fittings (22) and two coupling rods (24) linking the control bar (38) to the central engine casing, almost along the longitudinal axis of the latter. Links with play are envisaged between each of the coupling rods (24) and the attachment fitting (22), to ensure transmission of thrust forces in the event of rupture of one of the parts of the device. These links with play comprise pivoting axes (48) which intersect the longitudinal axes of the corresponding coupling rods (24).

  • Patent number: 6398161
    Abstract: An aircraft propulsion system (10) is connected to a strut, fixed to the wing or fuselage, by a fixing device comprising at least one rear mount (22) and two front mounts (24, 26). The rear mount (22) and a first (24) of the front mounts connect a main part (12a) of the frame (12) of the strut to the central casing (16) of the engine. The other front mount (26) connects a front part (12b) projecting from the strut frame (12) to the fan stator case (20) and mainly takes up the vertical forces (Z). Thus, the first front mount (24) can be simplified and bending or sagging of the engine is reduced.

  • Patent number: 6347765
    Abstract: A device for the attachment of an aircraft engine to a strut comprises a main attachment structure (18, 24) able to transmit normally to the strut forces exerted in two directions (X′, Y′), whereof one is mainly parallel to the longitudinal axis (OX) of the engine and the other mainly perpendicular to said axis and to a median plane common to the engine and the strut. The device also comprises an emergency attachment structure essentially constituted by an element (10) fixed to the strut and also forming part of the main attachment structure. The element (10), preferably implemented in the form of two coupled together parts (10a, 10b), comprises a pin (42) penetrating with clearance a recess formed on the aircraft casing (C).

  • Patent number: 6341746
    Abstract: A particularly simple and compact attachment device to be interposed between an aircraft engine casing (C) and a strut connected to the wing or fuselage of an aircraft, is designed so as to only transmit forces exerted in a single direction (OZ). The device comprises a crossbar (18), articulated to an element (10) fixed to the strut and also fulfilling an emergency function. The ends of the crossbar (18) are connected to the engine casing (C) by rods (24). The element (10) is preferably formed from two parts (10a, 10b), each being able to transmit all the forces in the direction (OZ).
