Abstract:
The pylon, intended to support a flying vehicle engine, includes a primary structure formed by at least one longeron and one panel, the panel including at least one end part provided with a notch, the longeron being provided with an end adapted to be positioned in the notch, the panel and the longeron being assembled by welding a part of the end to a part of the notch. A welded primary structure enables minimization of the blanks of parts associated with the longerons and with the panels by avoiding having recourse to the production of edges.
Abstract:
An assembly for an aircraft and comprising a wing comprising an airfoil box partly produced using a front spar, a mounting pylon arranged under the wing and comprising a primary structure formed as a primary box having a top spar extending at least partly under the airfoil box and having a slit, a bottom spar, lateral panels and a transverse reinforcing fixing rib, of which a bottom part is housed and fixed inside the primary structure and of which a top part passes through the slit. A fixing arrangement fixes the top part to the front spar. The fixing arrangement comprises a plurality of fixing bolts, where each fixing bolt fixes the top part to the front spar and has its axis at right angles to the fixing rib. Such an assembly allows the mounting pylon primary structure to be as close as possible to the wing.
Abstract:
An aircraft nacelle includes an air intake, connected to a means of propulsion, which defines a longitudinal direction, an outer wall, an inner duct including an annular flange connected, by means of connecting elements, to the means of propulsion, and a forward frame and a rear frame which connects the outer wall and the inner duct.The rear frame includes a first ring and a second ring, in longitudinal planes. The rings include a first connection to the outer wall. The first ring includes a second connection with the annular flange. The second ring includes a third connection with the inner duct. The third connection is remote from the second connection.

Abstract:
The invention relates to a wall made from a composite material comprising at least two layers of fibers (18, 18′) embedded in a resin matrix, a crack being able to spread in said wall in a direction of propagation, characterized in that it comprises at least one longilineal metal reinforcement (20), oriented in a direction secant to the direction of propagation, inserted between two layers of fibers (18, 18′) of the wall.
