摘要： A repair device and method for repairing a forward frame v-blade on an aircraft engine are described in which the repair device replaces a section of the forward frame v-blade. In one embodiment, the repair device includes a supplemental part, which is secured to the forward frame v-blade. The supplemental part includes a central web and a pair of legs with a leg thickness that is greater than the thickness of corresponding flanges on the forward frame v-blade. Fasteners such as rivets are used to couple the supplemental part to the forward frame v-blade.

摘要： A method and system of repairing an engine part having a cracked metal skin bonded to a honeycomb core includes removing a portion of the honeycomb that corresponds to a cracked portion of the metal skin. A crack in the metal skin originates from an edge of the engine part. A portion of the honeycomb is removed to form a slot in the honeycomb beginning at the edge of the part. A doubler is inserted into the slot in the honeycomb and is attached to an underside of the metal skin to form a lap joint between the doubler and the metal skin. In one embodiment, the portion of the metal skin that includes the crack remains. In an alternative embodiment, the cracked portion of the metal skin is removed and a metal patch is attached to the doubler such that the patch replaces the removed metal skin.

摘要： A doubler assembly repairs at least one damaged aperture of a composite flange. The doubler assembly includes an insert, an adhesive, and a support. The insert is positioned in the damaged aperture to provide compressive load transfer through the composite flange. The adhesive is positioned directly on at least a portion of the composite flange proximate the damaged aperture. The support is positioned over the adhesive.

摘要： A method of repairing a turbine engine component includes providing a turbine engine component having a first surface and a second surface. A porous structure extends from the first surface to the second surface. The first surface is exposed to a first pressure and the second surface is exposed to a second pressure. The first pressure is higher than the second pressure. A difference between the first pressure and the second pressure is used to pass a cleaning liquid through the porous structure from the first surface to the second surface.
