Abstract
The present invention relates to methods for repairing a structural weakness in an aircraft fuselage, or preventing the advancement of a structural weakness in an aircraft fuselage. Cold spray methods such as supersonic particle deposition have been shown to positively affect structural characteristics of sheet metal and lap joints as used in fuselage construction.
Claims12
A method comprising:
- (i) repairing a structural weakness, and/or (ii) preventing or inhibiting progression of a structural weakness in an aircraft structure, the structural weakness arising in a course of service of the aircraft, wherein repairing or preventing or inhibiting progression comprises:
- bonding a plurality of metallic particles to the structural weakness of the aircraft structure arising in the course of service of the aircraft, the bonding being effected under conditions allowing the plurality of metallic particles to form a substantially continuous layer having a depth of at least about 0.2 mm, wherein the aircraft structure is returned to at least a proportion of its original strength.
