Abstract:
A zone is provided between the forward pressure bulkhead in an aircraft and the floor. The nose section of the aircraft in which the flat surface pressure bulkhead including at least one transverse frame comprises at least two rods, of which one of the front ends is attached to the bulkhead and/or the frame and the other rear end is attached to a structural element, the two rods further apart from the front to the rear, thus providing a work space. Therefore, the rods provide a more comfortable work area while picking up part of the loads from the bulkhead to the floor.
Abstract:
The rudder bar includes two actuation arrangements, each provided with two pedals, each actuation arrangement having a frame provided with two rails arranged on either side of said frame and being in the form of a concave curve, and, associated with each one of said rails, a movable carriage, each one of said movable carriages bearing one of said pedals, each one of said movable carriages being configured such that it can be moved on the associated rail, for a direction command, under an action exerted by at least one foot of a pilot on at least one of said pedals.
Abstract:
A device for positioning a first piece relative to a second piece. The first piece comprises a free end with a first bore and the second piece comprises an engagement part with a second bore intended to come into correspondence with the first bore. The first and second bore are drilled to the definitive diameter thereof prior to the relative positioning thereof. The device comprises one or more positioning elements, which are able to position the first bore relative to the second bore along at least one of three geometric axes.
Abstract:
In order to facilitate the thermoacoustic insulation of an aircraft portion, a thermoacoustic insulation module for an aircraft comprises a mat and a load-bearing structure detachably attached to the mat and supporting the mat in a curved shape, with an axis of curvature parallel to a longitudinal direction of the mat. A thermoacoustic insulation method for insulating an aircraft portion comprises a step of inserting the thermoacoustic insulation module into the aircraft portion, followed by a step of detaching the mat from the load-bearing structure, followed by a step of attaching the mat to an aircraft structure delimiting the aircraft portion, followed by a step of removing the load-bearing structure from the aircraft portion.
Abstract:
A bendable element is formed at least from an inflatable envelope, a first bendable, elongate base plate attached to a first face of the inflatable envelope, a second bendable, elongate base plate, attached to a second face of the inflatable envelope and shorter than the first base plate, and links connecting the first base plate to the second base plate. The links are slack when the inflatable envelope is in a deflated state. The action of inflating the inflatable envelope causes the first and second base plates to bend in a direction of curvature extending from the first base plate to the second base plate, by means of the tensioning of the links such that the links extend along radii of curvature common to the first and second base plates while keeping the second base plate centered longitudinally relative to the first base plate.
Abstract:
A tooling making it possible to mount a module directly in an aircraft without making any modifications to the module. This tooling is made up of upper beams connected to the structure of the aircraft, lower beams secured to the module, lift elements connecting the lower beams to the upper beams and a drive system. The lift elements can move along the upper beams. The drive system makes it possible to convey the module to its functional location in the aircraft, by moving it along the upper beams via the lift elements. The principle of this tooling is to suspend the module in order to ensure and control its movement in the aircraft.
Abstract:
A forward part of an aircraft comprising a fuselage and a landing gear well housing a forward landing gear comprising a breaker strut designed to adopt an extended configuration when the landing gear is extended, configuration in which said breaker strut lies in a strut plane parallel to the transverse direction of the forward part. The forward part comprises a transverse beam resisting strut reactions located above the landing gear well and mounted on the fuselage at its two ends, the beam having a globally rectangular cross-section, in which the median plane parallel to the length of the rectangle is coincident with said strut plane.
Abstract:
A seating device with reduced bulk, for example for an aircraft. This seating device comprises a backrest which describes a circular translational movement towards the front and upwards of the device when the seating device is brought to the retracted configuration. A seating structure is provided comprising a bearing piece on which are fixed, side by side, a plurality of seating devices with reduced bulk. An aircraft is provided comprising a seating device with reduced bulk mounted in its cabin.
Abstract:
The invention relates to a secure access airlock enabling the communication between several rooms of an aircraft, the secure airlock being installed in an area of the aircraft between a first room and at least one second room, characterized in that it includes two mobile partitions provided in the form of portions of concentric cylinders, each of the partitions being capable of being moved, separately from one another, about a common axis, so as to provide a single opening therebetween which makes it possible to access either of the rooms, the two partitions being capable of moving over two concentric cylinders having different diameters.
Abstract:
A piece of furniture for an aircraft, including a plurality of carriages a first section forming an interface of use for a user with which at least one carriage may be taken and/or deposited in the piece of furniture and a second section allowing the said carriages to be circulated along at least first and second main directions substantially perpendicular to each other, at least in a plane of the aircraft for storing and/or delivering to the user at least one carriage, the first section and/or the second section including an arrangement for distributing at least one carriage from the second section towards the first section and vice versa.
