Abstract: A nacelle having a longitudinal axis and comprising a chassis, two articulated fan cowl doors and a sliding fan cowl door. Each articulated fan cowl door is rotatably mounted in an upper portion of the chassis, each about their own opening axis. The opening axes are parallel to the longitudinal axis. The articulated doors pivot between a closed position and an open position. The sliding fan cowl door, in its closed position, is placed between free edges of the articulated fan cowl doors. A sliding arrangement for the sliding door is configured such that, in the open position of either articulated door, the sliding fan cowl door can rotate about the longitudinal axis. The nacelle has fan cowl doors which take up less space when in the open position and which are more compact, in comparison to articulated fan cowl doors without a sliding fan cowl door.

The monitoring device comprises an acquisition unit to acquire signals transmitted or received by the line replaceable unit plugged into the connector during the exchange of messages with at least one other unit of the avionics system, for converting the signals into storable digital data and for assigning clock data to the data, and a storage unit for storing the storable digital data and the clock data.

Abstract: A cabin space dedicated to passengers and, beneath said cabin space, an under-cabin space which extends along the longitudinal axis of said aircraft. The under-cabin space comprises, distributed along two lines parallel to the longitudinal axis of the aircraft, two sets of systems which are able to carry out functions necessary for the operation of the aircraft. The two lines of sets of systems are disposed respectively in two lateral zones of the under-cabin space which are spaced apart transversely from one another and enclose a free central zone which extends along the longitudinal axis of the aircraft. This arrangement thus eliminates any technical zone from the under-cabin space, thereby facilitating the internal layout and maintenance.

Alternatively, or additionally, the card includes an output signal modulator and an output signal programmable digital matrix switch used to route the modulated output signals to an amplifier as a function of their type. The programmable digital matrix switches make it possible to address constraints regarding the segregation of varying numbers of input/output signals of different types.

Abstract: An aircraft comprising an air conditioning system for a cabin of the aircraft. The system comprises a mixer unit capable of mixing air that has already circulated in the cabin and fresh air from the engines of the aircraft. The air mixed in this way is then channeled towards the cabin to ventilate it. The aircraft has an airtight bulkhead allowing the cabin to be separated from a rear compartment, in such a manner as to prevent any direct exchange of air between said cabin and said compartment. This airtight bulkhead constitutes a wall delimiting the mixer unit, at least in part.

Abstract: An aircraft comprising a fuselage which has a central part with a cross section of constant geometry which comprises a floor. The floor comprises two lateral portions which are fixed respectively to two opposite lateral edges of the fuselage and which enclose a central portion to which they are fixed. One of the lateral floor portions is fixed to the central portion so as to allow a relative lateral movement between the two portions in the event of a modification in pressure inside the fuselage. The cross section thus deforms homogeneously when the fuselage is pressurized and the floor is not involved in maintaining the shape of the fuselage.
