Problems solved by technology

Therefore, as a series of maintenance operations are carried out, the cut area will gradually increase, which will eventually lead to a shortened service life of the aircraft
[0011] In addition, this repair method is unsatisfactory because it takes a long time, and this repair method increases the risk of new defects and the number of inspections, and at the same time, the number of inspections increases It also means reduced operating time and service life of the aircraft

Embodiment Construction

[0021] Such as Figure 4 As shown, a damaged aircraft fuselage 20 with an impact area 22 is depicted. In the description that follows, we analyze the fuselage and, by extension, the entire skin portion of the entire aircraft that is in contact with the flowing air, including the fuselage, wings and empennage.

[0022] Impact means all imperfections on the outer surfaces of the fuselage, especially depressions in said surfaces due to birds or other factors, which cause disturbances in the flow of air.

[0023] A method of repairing a damaged area of ​​a fuselage 20 comprising making at least one cut in the fuselage 20 so as to define the extent of a cut zone 24 including the impact zone 22 and obtaining an opening 26 in the fuselage, subsequently, with A steel plate 28 matching the rest of the fuselage 20 closes this opening, the size of the steel plate used must be greater than or equal to the size of the opening 26 .

[0024] In order to avoid stress concentration, the cutt...

Abstract

The object of the invention is method of cutting out a damaged area from an aircraft fuselage, in particular in order to repair said damaged area, consisting in making at least one cut-out in the fuselage (20) in order to delimit a cut-out area (24) encompassing the damaged area and comprising at least one rounded section, characterized in that it consists in making an opening (34) near said rounded section of the cut-out area (24) with a tool the diameter of which corresponds to that of the desired rounded section.

Description

technical field [0001] The invention relates to a method of repairing damaged areas of an aircraft fuselage. Background technique [0002] Aircraft fuselages have an outer skin, usually thin steel plates, reinforced by internal stiffeners that make up the skeleton. The exterior of the aircraft fuselage can be damaged by impacts from birds or other objects. If the impact marks are too severe, it may cause certain interference and hinder the flow of air around the fuselage. Therefore, it is necessary to replace the impacted parts of the fuselage. [0003] According to the Structural Repair Manual (S.R.M.: Structural Repair Manual), Section 51-27-00, the repair should start with cutting the steel plate. Such as figure 1 As shown, a polygonal cutting area 10 is formed on the steel plate around the impacted place 12 . Typically, the cutting area 10 is square or rectangular. [0004] In order to avoid stress concentration, the corners around the cutting area 10 are rounded. ...
