Problems solved by technology

This leads to a significant increase in the repair time just due to the removal of these metal parts and to a very cumbersome and limited repair method, notably requiring the radome to be transported away and into a remotely located heating chamber
[0006] The object of the present invention is to propose a repair method and a tool for its implementation that will alleviate the problems of time and difficulty of removing all metal parts from the radome and of transporting the radome and entering a suitable heating chamber

Embodiment Construction

[0031] Such as figure 1 and figure 2 As shown, the invention relates to a method for repairing a radome 1 , more specifically an aircraft radome in the example described below.

[0032] The radome 1 comprises a panel 2 made of a material transparent to electromagnetic waves, such as a composite material. The panel 2 has a double curvature to form a concavity in the form of a dome. The free periphery 3 of the radome 1 is usually connected in an articulated manner to the rest of the aircraft fuselage by any type of known means. In the following description, such as figure 1 and figure 2 shown, the radome will be considered to have been removed and removed from the aircraft. Panel 2 has an inner surface 4 and an outer surface 5 . The inner surface 4 of the panel is hollow. exist figure 1 and figure 2 In the embodiment shown, the free periphery 3 or at least a part of said periphery belongs to plane P: as a result, the radome can rest on a planar surface, in particular...

Abstract

A method for repairing a radome and a tool for implementing the same are provided. The method and tool for repair a damaged zone of an aircraft radome, solidifies a replacing member in a high pressure autoclave, using the actual radome itself as a heating chamber to avoid resorting to an autoclave and the removal of certain parts of the radome which cannot withstand the curing temperature needed for the repair. The radome (1) comprises a panel (2) exhibiting a double curvature forming a dome, the panel comprising at least one damaged zone (7). The method comprises the steps of closing an interior space of the panel (2) using a cap (8) to form a repair chamber (9). The surface of the panel (2) forms the repair chamber (9) containing the damaged zone (7). Another step is heating the space inside the repair chamber to form a heating chamber allowing the curing expected for repairing the damaged zone.

Description

technical field [0001] The invention relates to a method for repairing radomes, in particular aircraft radomes made of composite material, and to tools for carrying out such repairs. Background technique [0002] Most aircraft, especially commercial transport aircraft, have a radome at the nose. The radome obviously has the function of protecting the radar and has a structure made of electromagnetic wave permeable material such as composite material. The structure of the radomes can be damaged by various accidents such as bird strikes or hailstorms, and there may be dents, tears, nicks or any other form of damage requiring repair. [0003] Patent application FR 2953812 discloses an example of how to repair a fuselage made of composite material. As stated in that application, it is necessary to cut around the damaged area in order to remove it and place a patch in the opening made by cutting, which patch is fixed by curing in the case of a thermosetting resin. [0004] In ...
