  • Publication number: 20180178923
    Abstract: Fixation of an aircraft engine attachment pylon to the wing of an aircraft by means of an attachment device attached to a wing structure by means of first attachment through-members. The attachment device and the attachment pylon have respective junction surfaces clamped to each other by means of second attachment through-members. The junction surfaces extend along a plane forming an angle of less than 45 degrees with a vertical direction of the aircraft. A method for assembling the attachment pylon to the wing includes the positioning of the attachment pylon facing the attachment device, and then the clamping of the respective junction surfaces of the attachment device and of the attachment pylon to each other via the second attachment through-members.

  • Patent number: 8814079
    Abstract: A pylon for attaching a turbine engine of an aircraft having a rigid structure including protruding fittings each having a first orifice and a plurality of ties to attach the pylon onto a wing of the aircraft, the plurality of ties comprising two side front ties to take the thrust forces, the two side front being secured to the first orifices of the protruding fittings to attach the rigid structure firmly to the wing. The plurality of ties further comprises a center front tie positioned between the two side front ties, the center front tie including a ball joint to take forces in a lateral direction of the rigid structure.

  • Publication number: 20120056033
    Abstract: The invention relates to a pylon for attaching a turbine engine for an aircraft, having a rigid structure (10) and means for attaching the pylon on a wing of the aircraft, said means for attaching the pylon on the wing comprising two side front ties (11a, 11b) each designed so as to take the thrust forces and comprising a fitting (54) pierced with a first orifice (65) firmly attached to the rigid structure (10), as well as a yoke (66) firmly attached to the wing. According to the invention, a central front tie (15) positioned between the side ties comprises a ball joint (27), and is laid out between both side front ties so that the centre (72) of the ball joint is located, as seen along the transverse direction (Y), in each of the first two orifices (65) of the side front ties.
