  • Publication number: 20250197017
    Abstract: An aircraft propulsion assembly has an engine casing, an attachment pylon, a first front engine attachment with a pin and a blade fitted on the pin and fastened in an articulated manner on either side of a median plane to the casing and a second front engine attachment with a central rod in the median plane fastened in an articulated manner to a lower wall of the attachment pylon and to a fitting of the casing. The central rod is generally parallel to a longitudinal axis. In this arrangement, the casing is brought closer to the attachment pylon for a saving in terms of height.

  • Publication number: 20240336365
    Abstract: An engine pylon has a structure for fastening an aircraft engine beneath a wing and has two lateral faces. The structure has a tunnel laterally passing through it, between and through the lateral faces, and the engine pylon has a spreader housed in the tunnel and fastened in an articulated manner to each lateral face. A first end of the spreader has a first bore. A second end of the spreader has two second bores each forming a connection point with the engine. A rod is fastened in an articulated manner to the first bore and has two third bores each forming a connection point with the engine. Such an engine pylon has the ability to attach the engine, with reduced vertical bulk and with less drag.

  • Publication number: 20240052781
    Abstract: Assembly including an aircraft turbine engine and a pylon for mounting the turbine engine to an element of the aircraft. The pylon includes members for suspending the turbine engine, the members being connected to the turbine engine in at least one plane which is perpendicular to the axis and which is located upstream of the combustion chamber of the turbine engine, such that the turbomachine is cantilevered to the pylon, The assembly further includes at least one damper which connects the turbomachine to the pylon and which is located in a plane perpendicular to the axis located downstream of the combustion chamber, the damper being configured to limit the relative movements between the turbine engine and the pylon without transmitting force.
