Abstract
Methods and apparatus are provided for repairing a damaged area within a cored passage of a component. The method includes providing a repair tool that has a support portion, a leading portion extending from a first end of the support portion, and a trailing portion extending from a second end of the support portion. The leading portion of the repair tool is inserted into a first opening of the cored passage, and is threaded through the cored passage until the support portion is positioned at the damaged area within the cored passage. A restoration activity is performed on the damaged area as the support portion supports the cored passage proximate to the damaged area. Upon completion of the restoration activity, the repair tool is removed from the cored passage.
Claims17
A method of repairing a damaged area within a cored passage of a component, comprising the steps of:
- providing a repair tool with a hollow support portion, a hollow leading portion extending from a first end of the support portion, and a hollow trailing portion extending from a second end of the support portion, wherein the support portion is cylindrical and has a first diameter, the leading portion and the trailing portion each have a second diameter that is less than the first diameter, and wherein at least one of the leading portion or the trailing portion includes evenly spaced distance markings on an outer surface thereof, each distance marking representing a distance from an end the support portion to the distance marking;
- inserting the leading portion of the repair tool into a first opening of the cored passage;
- threading the repair tool through the cored passage until the distance markings indicate the support portion is positioned at the damaged area within the cored passage;
- performing a restoration activity on the damaged area as the support portion supports the cored passage proximate to the damaged area;
- and
- removing, upon completion of the restoration activity, the repair tool from the cored passage.
A repair tool for use in repairing a damaged area within a cored passage of a component, the repair tool comprising:
- a hollow support portion formed of a first material and having a first end and a second end, the support portion being cylindrical and having a first diameter;
- a hollow leading portion formed of a second material that is different from the first material and extending from the first end of the support portion to a first distal end, the leading portion having a second diameter that is less than the first diameter;
- and
- a hollow trailing portion formed of the second material and extending from the second end of the support portion to a second distal end, the trailing portion having the second diameter,
- wherein the first and second distal ends are each tufted, and
- wherein at least one of the leading portion or the trailing portion includes evenly spaced distance markings on an outer surface thereof, each distance marking representing a distance from the support portion to the distance marking.
A method of repairing a damaged area within a cored passage of a component, comprising the steps of:
- providing a repair tool with a hollow support portion, a hollow leading portion extending from a first end of the support portion, and a hollow trailing portion extending from a second end of the support portion, wherein the support portion is cylindrical and has a first diameter, the leading portion and the trailing portion each have a second diameter that is less than the first diameter, and wherein at least one of the leading portion or the trailing portion includes evenly spaced distance markings on an outer surface thereof, each distance marking representing a distance from the support portion to the distance marking;
- inserting the leading portion of the repair tool into a first opening of the cored passage;
- threading the repair tool through the cored passage until the distance markings indicate the support portion is positioned at the damaged area within the cored passage;
- circulating a coolant between the trailing portion and the leading portion and through the support portion;
- monitoring one or more parameters of the coolant;
- automatically controlling flow of the coolant based on the one more monitored parameters;
- performing a restoration activity on the damaged area as the support portion supports the cored passage proximate to the damaged area;
- and
- removing, upon completion of the restoration activity, the repair tool from the cored passage.
