Abstract
A turbomachine modification apparatus includes a machining device, and a machining device mount attached to the machining device. The machining device mount is configured to radially and axially adjust a position of the machining device. A blade mount is configured to be attached to one or more turbomachine blades. The blade mount is attached to the machining device mount.
Claims16
A method for modifying a static seal or shroud in a turbomachine, the method comprising:
- attaching a blade mount to one or more turbomachine blades;
- attaching a machining device mount to the blade mount;
- attaching a machining device to the machining device mount, the machining device including a machining bit;
- positioning the machining bit in a desired location with respect to the static seal or shroud;
- activating the machining device;
- controlling a rotor of the turbomachine so that the rotor rotates at a desired speed;
- and
- wherein rotation of the rotor moves the machining device in an arcuate and circumferential path along the static seal or shroud thereby machining the static seal or shroud;
- the blade mount further including:
- an aft plate and a forward plate, the aft plate configured to be placed on an aft side of the turbomachine blades and the forward plate configured to be placed on a forward side of the turbomachine blades;
- and
- each of the aft plate and the forward plate includes grooves generally conforming to a profile of the turbomachine blades.

A method for modifying a static honeycomb seal or shroud in a turbomachine, the method comprising:
- attaching a blade mount to one or more turbomachine blades;
- attaching a machining device mount to the blade mount;
- attaching a machining device to the machining device mount, the machining device including a machining bit, the machining bit configured for machining the static honeycomb seal or shroud;
- positioning the machining bit in a desired location with respect to the static honeycomb seal or shroud;
- activating the machining device;
- controlling a rotor of the turbomachine so that the rotor rotates at a desired speed;
- and
- wherein rotation of the rotor moves the machining device in an arcuate and circumferential path along the static honeycomb seal or shroud thereby machining the static honeycomb seal or shroud, the blade mount further including:
- an aft plate and a forward plate, the aft plate configured to be placed on an aft side of the turbomachine blades and the forward plate configured to be placed on a forward side of the turbomachine blades;
- each of the aft plate and the forward plate comprising grooves generally conforming to a profile of the turbomachine blades;
- and
- wherein the aft plate and the forward plate are substantially parallel to each other when installed on the turbomachine blades.
