Abstract
A blade bonding device permits individual blades to be bonded to a blade stub for the purpose of replacing a damaged blade. The device includes a clamp frame and hydraulic ram. A blade holder arranged in contact with the axially moveable ram shaft is guided by a precision slot and pin arrangement from the frame. The clamp engages the inner surfaces of the rim of the rotor disk, and has a cooling passage through this location near the rim. The advantages of the clamp and cooling means are to not mechanically or thermally stress the disk.
