    摘要： La servocommande comporte :
    - un dispositif de pilotage configuré pour contrôler un dispositif de puissance en fonction d'une commande de déplacement, le dispositif de pilotage (60) comprenant une unité de pilotage (62) comportant :
    + un ensemble d'accessoires électroniques, mécaniques et/ou hydrauliques (70) en communication fluidique avec le vérin hydraulique ; et
    + un corps (72) délimitant un réseau de cavités tubulaires (98) connectant fluidiquement les accessoires électroniques, mécaniques et/ou hydraulique (70), le corps (72) comprenant une surface externe (90), au moins une première portion de raccord entre le réseau et un vérin hydraulique et au moins une deuxième portion de raccord entre le réseau et le vérin hydraulique, une fibre neutre (100) étant définie pour chaque cavité tubulaire (98).


    La fibre neutre (100) d'au moins une cavité tubulaire (98) est courbe.

    摘要： Hydraulic actuator systems of aircraft are described. The hydraulic actuator systems include a hydraulic actuator (101, 201, 301) having a housing and piston therein. The piston includes a piston head separating the housing into a retract cavity and an extend cavity. An actuator controller (112) is hydraulically coupled to the retract cavity by a first hydraulic line and hydraulically coupled to the extend cavity by a second hydraulic line and configured to control a hydraulic pressure within each of the retract cavity and the extend cavity to control actuation of the hydraulic actuator (101, 201, 301). A position-lock controller is arranged along at least one of the first hydraulic line and the second hydraulic line, the position-lock controller is configured to hydraulically decouple the actuator controller (112) from at least one of the retract cavity and the extend cavity.

    摘要： There is provided a control module for a hydraulic system. The module comprises a tank and a plurality of valves. The tank is configured to store hydraulic fluid and is substantially cylindrical. The plurality of valves fluidly connect with the tank and are configured to control distribution of hydraulic fluid from the tank to one or more components of the system. The plurality of valves are spaced around a circumference of the tank. One or more passages fluidly connect the tank with at least one of the plurality of valves and/or a first of the plurality of valves with a second of the plurality of valves.

    摘要： A vertical take-off and/or landing aircraft (1) comprising: a fuselage (2) having a longitudinal axis (d); a pair of semi-wings (3) protruding from the fuselage (2) in a transversal direction with respect to the longitudinal axis (D); a pair of a predetermined breaking areas (11) of the semi-wings (3) defining respective preferred rupture sections (12) at which the respective semi-wings (3) are designed to break, during operation, in a controlled way moving along a preferred collapse trajectory in the event of impact; and at least one fluidic line (13) configured to convey at least one service fluid from and/or towards at least one said semi-wing (3) and crossing at least one of said preferred rupture sections (12); the aircraft (1) comprises a self-sealing coupling (15) movable between a first configuration in which it enables the flow of said service fluid from and/or towards the semi-wing (3), and a second configuration in which it prevents the above-mentioned flow and the spilling of the service fluid from the fluidic line (13); the self-sealing coupling (15) is movable from the first to the second configuration via the movement of the semi-wing (3) along the preferred collapse trajectory.
