Problems solved by technology

On the other hand, compared with the first solution, since the plurality of fasteners need to be removed and reinstalled each time the radome is opened or closed, the second solution needs to take more time to remove the radome. remove and / or open the radome

Embodiment Construction

[0040] figure 1 and FIG. 2 : The radome ( 1 ) according to the invention comprises a double curvature surface ( 12 ) made of a material capable of transmitting electromagnetic waves, preferably a honeycomb type composite material. The radome (1) comprises a rigid one-piece ring (11) extending from a junction end (10) fixed to the aircraft fuselage to the location of a locking device (20). This rigid one-piece ring maintains the consistency of the shape of the radome—in particular during opening of the radome, for example during inspection or maintenance operations on a radar arranged below the radome.

[0041] The rigidity of the ring (11) also means that the radome can remain fixed to the fuselage with a reduced number of fuselage anchoring and locking points. On the other hand, the stiffness of the ring does not allow a complete smoothing and adjustment of the shape of the junctional end (10) to the shape of the fuselage. In order to allow the junctional ring of the radom...

Abstract

The invention relates to a radome (1) for an aircraft and, specifically, to a device for connecting said radome to the structure of said aircraft. The radome that is the subject matter of the invention includes a plurality of locking units suitable for engaging the opposing surfaces of the fuselage (10) of the aircraft and the radome (1), each unit comprising: a locking means (20) suitable for exerting a tractive force on the surface of the fuselage, substantially normal to the latter, by means of the attachment means; a centring means suitable for passing on the shearing forces substantially tangential to the opposing surfaces of the fuselage and the radome; the locking means (20) being placed so as to be located inside the resulting stress cone on the centring means in order to minimise the bending strain generated by assembly in the radome (1).

Description

technical field [0001] The invention relates to a radome for an aircraft, and more particularly to means for connecting said radome to the structure of said aircraft. Background technique [0002] Most aircraft, more particularly commercial aircraft, include a radome located in the nose cone of the fuselage. In addition to the aerodynamic role of the radome, this radome also protects the radar. The radomes are therefore made of materials—usually composites—that allow electromagnetic waves to pass through. The functionality of this part introduces several constraints in the design and manufacture of the part: [0003] - the accessibility of the radar below the radome means that the radome must be a removable part, preferably one that can be easily removed or stowed away; [0004] - the role of the radomes in protecting the radar, and the positioning of the radomes in areas especially exposed to different types of impacts, these mean that the part must be particularly resis...
