Abstract: A fuselage element including a first fuselage segment including a skin, and a junction device for connecting the first segment to a second adjacent fuselage segment is disclosed. The first segment extending along the longitudinal axis of the fuselage element includes stiffening elements extending along the axis. The end of at least one stiffening element extends beyond a free edge of the skin by a predetermined length.

Abstract: The invention relates to a fuselage element (1) comprising a first fuselage segment (2a) comprising a skin (3a), and junction means (4) for connecting the first segment (2a) to a second adjacent fuselage segment (2b), the first segment (2a) extending along the longitudinal axis (X) of the fuselage, wherein the fuselage element (1) includes stiffening elements (5a) extending along the axis (X). The end (5a1) of at least one stiffening element (5a) extends beyond a free edge (7) of the skin (3a) by a predetermined length (L).

Abstract: An arrangement configured to connect an evener bar onto a rigid structure of an aircraft engine mount, including a pin system slidingly mounted in a first passageway of a bracket to permit its displacement along a first longitudinal axis, in a first direction from a normal extended position to a retracted position in which the pin system is retracted within this same bracket, and conversely. The arrangement also includes a pin extending member carried by the system and configured to be moved parallel to the longitudinal axis, in a second direction from a normal retracted position to an extended position in which the pin extending member is joined to the system and projects beyond the system, and conversely.

Abstract: The present invention relates to an anti-missile protection system for an aircraft (30), and applies in particular to the protection of civilian and military airplanes, and to that of helicopters, against the firing of ground-to-air missiles equipped with homing heads. According to the invention, the system comprises at least one optoelectronic module (10, 10A, 10B), each module being equipped with a device for detecting and tracking missiles in a given space, with, in particular, a missile jamming laser beam emitting head (23, 44), and, for each optoelectronic module, a service box (11, 11A, 11B) for controlling and supplying power to the module, each box being remote from the optoelectronic module that it controls and also comprising the electronics for controlling the jamming laser of said module.

Abstract: The present invention relates to a modular optronics system onboard a carrier, such as a combat aircraft, a helicopter or a drone. The system as claimed in the invention comprises at least one optronics element having a target line that can be addressed in a given space, and comprising a mechanical structure designed to be the interface with the carrier and a target line orientation and stabilization mechanism. According to the invention, the mechanical structure comprises a module forming a section with three interfaces, including said interface with the carrier and two lateral interfaces that can receive a lateral module. The optronics elements and the target line orientation and stabilization mechanism are directly incorporated in the module forming a section.
