An assembly comprising a wing and a reactor mast fixed to the wing. The primary structure of the reactor mast comprises a first fixing lug and starboard and port fixing lugs, the wing carries a first fitting and starboard and port fittings, the fixing lugs being joined to the fittings with shackles having three fixing points, and the first lug being fixed to the first fitting.

Assembly for an aircraft comprising a wing and a reactor mast for coupling a propulsion system to said wing

An engine mounting system comprising an engine with a center of thrust, a first engine mount having a longitudinal axis that intersects with the center of thrust, a second engine mount having a longitudinal axis that intersects with the center of thrust, the longitudinal axis of the first engine mount intersecting the longitudinal axis of the second engine mount at the center of thrust, wherein the engine includes a first connection point at a first point on the engine, the first engine mount to couple the first connection point to a pylon, a second connection point at a second point on the engine, the second engine mount to couple the second connection point to the pylon, and a third connection point at a third point on the engine symmetrical to the second point across a centerline, the second engine mount to couple the third connection point to the pylon.

Forward engine mount for a half or full wraparound pylon

A propulsion assembly for an aircraft, having a turbomachine, a pylon, and a device for reacting thrust forces having a main fitting, a spreader pivoting on the main fitting and having an opening, two rods articulated to the turbomachine and to the spreader, a secondary fitting fastened beneath the pylon and having a secondary female clevis constituted of two secondary arms passed through by holes of oblong shape and aligned along a secondary axis (R), wherein the spreader is housed in the secondary female clevis of the secondary fitting, wherein the opening is coaxial with the secondary axis (R), and a backup connection pin inserted with a tight fit into the opening and with clearance into the holes. Also an aircraft with such a propulsion assembly.

Aircraft propulsion assembly having a device for reacting thrust forces

An assembly including a connecting device, connecting first and second parts, including first and second links positioned on respective opposite sides of the first and second parts and an interleaved stiffener, positioned between the first and second links, having a first contact face oriented toward the first link and a second contact face oriented toward the second link, parallel to the first face, the first and second contact faces being separated by a distance equal to that separating the first and second links. This interleaved stiffener makes it possible to limit the risks of bending of the links when they are loaded in compression.

Assembly including two links and an interleaved stiffener, aircraft engine attachment including at least one such assembly

A linking device connecting an aircraft engine and a primary structure of an aircraft pylon, comprising a support connected to the primary structure, a spreader having a central part connected to the support and a first and a second end that are connected to thrust rods, at least one limiting system for limiting the travel of the spreader having an upper and a lower stop between which is positioned the first or second end of the spreader, the upper and the lower stop being connected to one another so as to form a single part connected to a fitting secured to the support.

Device for connecting an aircraft engine and a primary structure of an aircraft pylon comprising a rudder and a system for limiting the displacement of the rudder incorporating a double stop, aircraft comprising such a device

An assembly of a pylon and of a wing of an aircraft, the pylon including a primary structure with a rear face and an upper spar. The assembly includes a rear fastening system including a pair of vertical shackles articulated between the rear face of the primary structure and a first shoe fastened to the wing, wherein the shackles are fastened to the primary structure by a clevis-type connection, and a pair of transverse shackles articulated between the rear face of the primary structure and a second shoe fastened to the wing, wherein the shackles are fastened to the primary structure by a clevis-type connection. With such an assembly, the bulk of the rear fastening system is reduced.

Assembly of a pylon with a wing of an aircraft

An assembly for an aircraft that has a wing and an engine pylon having a primary structure with right-side and left-side panels, an upper and a lower spar and a rear rib, two sets of upper or lower shackles, one set fastening the right-side panel to the wing, and a second set fastening the left-side panel to the wing, a fastening element secured to the rear rib or to the lower spar, a rear rod connecting the fastening element to the wing, a transverse shackle connecting the upper spar to the wing, a line connecting two centers of the transverse shackle being oriented transversely relative to a longitudinal axis of the engine pylon, and a reinforcing panel, at each joint between a right-side or left-side panel and an upper or lower shackle, which is fastened along a height against the panel and to which the shackle is also fastened.

A junction of a pylon with an aircraft wing, the pylon including a primary structure extending from front to rear along a longitudinal axis and in the form of a box with a rear face and an upper spar forming an upper face of the box, a longitudinal median plane separating the primary structure into two parts, left and right, the junction comprising a rear attachment system for attaching the pylon to the wing, this system being arranged at the rear of the primary structure, the rear attachment system including a shoe attached beneath the wing, the shoe being connected, via at least one articulated connecting rod, to a fitting attached to the rear face of the pylon by an articulation whose articulation pin, termed the horizontal articulation pin, is perpendicular to the longitudinal median plane, and the shoe being connected to the upper spar via a force reacting system.

Junction of a pylon with an aircraft wing

An assembly of an engine with a pylon, including a force reacting assembly having a connection device and two rods, the connection device including a shoe. A spreader extends between first and second ends and has a central part connected to the shoe by a main connection including a main rotation pin and axis in a plane of symmetry of the connection device. Two fittings are on either side of the plane of symmetry each having two arms between which the spreader is positioned. A first, respectively second, rod includes a front end fastened to the engine and a rear end fastened to the first, respectively second, end of the spreader and to the first, respectively second, fitting by a secondary connection. Two extensions of the spreader are each associated with a pair of elastic stops. For the first, respectively second, end of the spreader, each stop is between an arm of the first, respectively second, fitting and the extension.
