Abstract: The invention relates to an aircraft wing comprising a stationary central wing body as well as at least one mobile leading edge flap intended for being moved relative to the stationary central body between an extended position and a retracted position, the wing comprising a device for moving the mobile leading edge flap, the device being provided with at least one mobile drive rail including a front end connected to the mobile flap. According to the invention, the movement device comprises a linear electric motor including: a primary assembly provided with at least one stationary carriage comprising coils, the primary assembly being rigidly connected to the stationary central body of the wing; and a mobile secondary assembly including a magnetic track arranged on the drive rail.

Abstract: A system for dual management of anti-icing and boundary layer suction for an aerofoil of an aircraft, including: at least one anti-icing channel and at least one suction channel; a device monitoring boundary layer suction and a device monitoring anti-icing; a first duct collecting the suction air communicating with the suction channel and a second duct supplying anti-icing air connected to the device and communicating with the anti-icing channel; a three-way valve to which the first duct, a suction duct, and a duct for discharging the anti-icing air are connected; and a duct collecting anti-icing air connected to the anti-icing channel, and to the first duct.

Abstract: Thin walled compartmented tubular structure and its manufacturing process. The elbow or T-shaped structure, includes an external wall (14)and continuous internal walls (22) made in one piece. This therefore materializes, between the inlet (10) and each outlet (12) of the structure, at least one continuous passage to direct a fluid circulating inside it. The structure according to the invention is manufactured by diffusion welding and superplastic forming, from titanium alloy sheets. One application is for aircraft de-icing circuits.

Abstract: A structure (10) in the shape of an aerodynamic panel in which adjacent cells (20a, 20b) are formed by placing a stack of three metal plates in a mold. After diffusion welding of the plates at the required locations, a first variable pressure is applied in a first series of cells (20a) formed between the outer plate and the intermediate plate and a second independent pressure approximately constant and lower than the first is applied in the other cells (20b) and on the inner face of the stack. Thus, this partially forms the cells and shapes the structure in contact with a complementary surface of the mold. The final conformation of the cells and the structure is obtained by applying a second pressure cycle in the cells and on the inner face of the stack.
