    Abstract: An airplane comprising a fuselage, two wings, a rear tail unit comprising a horizontal tail provided with two tail ends, and at least two engines arranged on the fuselage on either side of a vertical plane of symmetry of the airplane, the airplane having a longitudinal axis, the engines being mounted so as to be able to be displaced, at least in flight, on the fuselage, substantially parallel to the longitudinal axis, and the tail ends being mounted so as to be able to be pivoted, at least in flight, relative to the horizontal tail, the airplane thus having a configuration that changes in flight.

    Abstract: A landing assistance system includes a module for acquiring environment and current flight parameters of the aircraft, a module for generating flight and navigation symbology to be displayed on the display device at least from current flight parameters, a module for generating a land topography of terrain overflown by the aircraft, a transmission module configured to transmit a signal to the display device that represents the flight and navigation symbology and the synthetic representation, the symbology generating module including a sub-module for displaying a mock-up at a predetermined non-zero positive pitch angle relative to a median line of the display zone. The system allows a landing to occur in good conditions by virtue of the enlargement of the lower part of the display zone.

    Abstract: A propulsion assembly for an aircraft comprising a pylon and a bypass turbomachine having a fan duct in which an air flow flows. The turbomachine further comprises an air intake system with a cold bleed air device for bleeding some of the air flow from the fan duct, the device comprising a sliding scoop comprising an upstream face that is open to allow the air to pass and a lower side that has an air outlet opening connected to an exchanger. The scoop is able to slide between an open position in which the scoop extends at least in part into the fan duct and in which part of the air flow in the fan duct rushes into the scoop via the upstream face thereof, and a closed position in which the scoop does not extend into the fan duct and has its upper side closing off the cutout.

    Abstract: A turbofan having a nacelle delimiting a duct for a bypass flow and including a fixed structure including a guide vane support with guide vanes, a mobile cowl movable in translation between an advanced position and a retracted position, arms, each one being mobile in rotation on the guide vane support between a stowed position and a deployed position and comprising a distal end and a proximal end, for each pair of adjacent arms, a flexible screen extending angularly between the two arms, and of which an exterior edge is attached to the guide vane support, and wherein the distal end of each arm is fixed along the interior edge, a link rod mounted articulated between the distal ends, actuators to cause the mobile cowl to move, and an operating system which moves each arm. Such an arrangement allows a reduction in weight.

    Abstract: A turbofan has a nacelle delimiting a duct for a bypass flow and comprises a fixed structure comprising a guide vane support with guide vanes, a mobile cowl able to move in translation between an advanced position and a retracted position, arms, each one being mobile in rotation between a stowed position and a deployed position and comprising a distal end and a proximal end, a flexible screen, of which an exterior edge is attached to the guide vane support rearward of the guide vanes, and wherein the distal end of each arm is fixed along the interior edge, actuators to cause the mobile cowl to move, and an operating system which moves each arm. Replacing the reversal doors and their drive mechanisms with the flexible screen and the set of rotationally-mobile arms allows a reduction in weight.

    Abstract: A device and an inspection method for inspecting screw and nut assemblies in an aircraft, comprising a mechanical tool and a digital human-machine interface. The mechanical tool comprises a housing comprising a bearing surface defining a reference plane, a support beam mounted to be translationally mobile inside the housing, a linear encoder configured to measure, in use, a distance between the reference plane and a bottom face of the mobile support beam. The digital human-machine interface comprises a central unit, a display screen, an application and a database in which are stored validity ranges or standardized distances relating to types of assembly, the application and the database being loaded and operational in the central unit.

    Abstract: An aircraft duct assembly comprising at least two ducts extending along a general direction of rectilinear extent, each duct being an electrical, hydraulic or aeraulic duct connected to a duct support. The duct support comprises a first slideway element configured to cooperate with a second slideway element to form a slideway in the general direction of extent of the ducts. The duct assembly can thus be inserted, after mounting, by translation along the direction of the slideway into an aircraft fuselage portion. The mounting of the duct assembly and installation thereof in a fuselage are simplified, and the duct assembly is more reliable.

    Abstract: A grating for the formation of a reverse flow of a turbofan engine and comprising fins of a first type having a curved profile whose rounding is oriented aft and whose center of curvature is forward relative to the fin of the first type, fins of a second type having a curved profile whose rounding is oriented aft and whose center of curvature is forward relative to the fin of the second type. In this grating, each fin of one of the two types is inserted between two fins of the other type moving from forward to aft and the cord of the fins of the second type is smaller than the cord of the fins of the first type.

    Abstract: An apparatus for reducing brake wear having a brake de-selection function for selectively disabling at least one brake on a vehicle; and a controller. The controller is configured to receive torque information which relates to torque reacted by a brake on the vehicle during a braking event and wheel speed information which relates to a speed of a wheel associated with the brake during the braking event; calculate an energy input into the brake during the braking event, based on the received torque information and the received wheel speed information; determine whether the calculated energy input meets at least one predefined energy input criterion; and activate the brake de-selection function if the calculated energy input meets the at least one predefined energy input criterion.
