Abstract
Official abstract text for this publication.
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 repair part and a splice plate, the combination of which is secured to the forward frame v-blade. The repair part includes a repair part web and a pair of stiffening legs with a leg thickness that is greater that the thickness of corresponding flanges on the forward frame v-blade. The splice plate is configured to accommodate for the increased thickness of the stiffening legs, providing by way of example a reduced thickness area compatible with the repair part. Fasteners such as rivets are used to couple the repair device to the splice plate, and to couple the splice plate to the forward frame v-blade.
First claim
Opening claim text (preview).
What is claimed is: 1. In a gas turbine engine for an aircraft, a forward frame v-blade comprising: a circumferential shape disposed about the gas turbine engine, the circumferential shape having a v-blade cross-section with an upper v-blade flange, a lower v-blade flange, and a v-blade web extending therebetween; a splice plate coupled to the circumferential shape, the splice plate including a splice plate body having a repair part engagement area; a repair part including a c…
