Abstract: A device measures a flight parameter of an aircraft which has a radome. Systems measure the deformation of a wall of the radome due to forces exerted by the air on the radome. A computer computes the flight parameter from deformation measurements obtained by the systems. The systems have an optical fiber carried by the radome provided with Bragg gratings. Each fiber has a plurality of Bragg gratings distributed over a length of the fiber so as to distribute the Bragg gratings over the radome when the fiber is installed.

Abstract: A system for emitting and/or receiving electromagnetic waves embedded in an aircraft, the aircraft including an emitting and/or receiving device for emitting and/or receiving electrical signals, a radome having an electrically insulating protective envelope (12), on which at least one lightning arrester strip (21) is arranged, the radome being attached to a metal frame of the aircraft (30), a first part of the at least one lightning arrester strip is electrically connected to the metal frame of the aircraft, a second part of the at least one lightning arrester strip is connected to the emitting and/or receiving device via a metal element (35) of a predetermined shape, the at least one lightning arrester strip forming an antenna and a part of the metal element (35) is placed at a predetermined distance (d) from a part of the metal frame of the aircraft (30) for forming a capacitive link between the metal element and the metal frame of the aircraft.

Abstract: A device for measuring at least one flight parameter such as the airspeed, the sideslip angle or the angle of attack, or any other parameter dependent thereon, of an aircraft including a radome, including systems for measuring the deformation of the radome wall due to forces exerted by the air on the radome and a computer for computing from deformation measurements obtained by the systems the required flight parameter or parameters. The systems include at least one optical fiber carried by the radome provided with Bragg gratings, each fiber including a plurality of Bragg gratings distributed over a length of the fiber so as to distribute the Bragg gratings over the radome when the fiber is installed.

Abstract: A method for opening a dome for the protection of a device to be protected, fitted in a part described as fixed, in which, in the initial position before opening, a generally plane interface separates the dome from the fixed part, is provided. The method includes connecting the dome to the fixed part by at least two independent double-link connections that are movable in rotation between the dome and the fixed part. The links in a single connection being fitted in common to the dome and to the fixed part to form overall a pantograph in the shape of an isosceles trapezium which, during opening, opens out by pivoting until maximum opening is achieved, so that the dome moves away from the fixed part via a combination of movements in translation and in rotation.
