A fixture for repairing a fan blade, comprising:
- a base having a first side, a second side, a tip end, and a foot end;
- a first support coupled at the first side and perpendicular to the base;
- a second support coupled at the second side and perpendicular to the base;
- and
- a footboard, perpendicular to the base, coupled orthogonally between the first support and the second support at the foot end of the base, wherein the footboard comprises a chuck adapted to receive the foot of a fan blade.
A method of manufacturing a fixture for repairing a fan blade, the method comprising:
- coupling a first support to a first side of a base and perpendicular to the base;
- coupling a second support to a second side of the base and perpendicular to the base;
- coupling a footboard comprising a chuck adapted to receive the foot of a fan blade orthogonally between the first support and the second support at a foot end of the base and perpendicular to the base.
A method of repairing a fan blade, the method comprising:
- inserting a foot of the fan blade comprising a damaged portion into a fixture for repairing the fan blade through a notch of a footboard coupled to a chuck adapted to receive the foot of a fan blade and into a keyway of the chuck, wherein the footboard is coupled at a foot end of a base and perpendicular to the base and orthogonally between a first support and a second support, the first support coupled to a first side of the base and perpendicular to the base, the second support coupled to a second side of the base and perpendicular to the base;
- and
- rotating the chuck to an angle such that a plane defined by a circumference of the damaged portion is substantially parallel to a plane of the base defined by a first side, a second side, the foot end, a the tip end of the base.
