Abstract: A nacelle comprising a fixed structure, a fixed cowl, a mobile cowl, and a motor arrangement to translationally displace the mobile cowl from a closed to an open position on the fixed structure. The nacelle comprises a window delimited between the fixed and mobile cowls and open between a secondary turbojet and the outside, a thrust-reversing door rotationally mobile about a rotational axis between retracted and active positions, and a driving mechanism which coordinates and defers the switch from the retracted to the active position with the switch from the closed to the open position. The driving mechanism comprises two connecting rods rotationally mobilely mounted on the fixed structure and bearing a wheel, a mobile cowl groove which slidingly receives the wheel, a guide integral to the thrust-reversing door, and a runner rotationally mobilely mounted between the connecting rods, as well as mounted to slide along the guide.

Abstract: A nacelle has a fixed cowl and a mobile cowl, which is movable along a translation path between closing and opening positions, a window delimited by the fixed cowl and the mobile cowl and open between an airflow and exterior of the nacelle, a reverser flap rotatably mounted to move between closed and open positions, and a drive mechanism configured to control passage of the reverser flap between the closed and open positions as the mobile cowl moves between the closed and open positions. From the closing/closed positions, the drive mechanism assures a translation of the mobile cowl and a rotation of the reverser flap toward their respective opening/open positions. From the open/opening positions, the drive mechanism assures a rotation of the reverser flap and a translation of the mobile cowl toward their respective closed/closing position. In some embodiments, the nacelle further includes an additional, or second, flap.

Abstract: A nacelle for a ducted fan turbojet engine comprising an engine. The nacelle comprises a fixed cowl, an upstream wall bounding off, with the engine, a working section for a secondary flow, a movable cowl with an interior wall and an exterior wall, and movable in translation between a closing position where the exterior wall adjoins the fixed cowl and the interior wall prolongs the upstream wall, and an opening position where the exterior wall is distant from the fixed cowl so as to open a window and the interior wall is distant from the upstream wall, an inverter flap between the interior wall and the exterior wall mounted to be free in rotation about an axis of rotation situated on the interior wall and a drive mechanism for moving the movable cowl.

Abstract: The invention relates to an aircraft control system containing several aircraft control computers (14, 16, 18, 20) for said aircraft, said system having at least one server (10) which: contains at least one aeronautical data base (12); is connected to at least one subassembly of said control computers through data transmission links (26a, 26b, 26c, 26d); is able to supply information from said at least one aeronautical data base to the computers of said control computer subassembly, said at least one server being able to supply information from said at least one aeronautical data base to a computer of said control computer subassembly, in a period of time less than a predetermined duration, upon request from said computer, when said information is not available in a local data base of said computer.
