Embodiment Construction

[0010] One embodiment of the invention provides a segmented rotor for a turbomachine comprising welded together sections which may comprise more than one turbine blade row of turbine blades. The segmented rotor may include one or more rings combined with one or more disks and include a generally hollow interior to reduce the weight and thermal mass of the segmented rotor compared to current rotor designs.

[0011] see now figure 1 , a schematic diagram of one embodiment of a turbine 20 is shown that utilizes a plurality of turbine blades in operative communication with a rotor 24 to convert thermal and kinetic energy into mechanical energy by virtue of the rotation of the rotor 24 relative to the outer frame 26 . The turbine 20 may be a gas turbine that converts thermal and kinetic energy generated by the expansion of the combustion gases 12 to provide mechanical energy to propel a vehicle such as an airplane, ship, or train, to generate electricity, or to provide utility Me...

Abstract

The invention relates to a turbine rotor equipment and system. The segmented turbine rotor (28) has a plurality of rows (52) of a plurality of turbine blades (48). At least one rotor segment (30) of a plurality of rotor segments (30) of the segmented turbine rotor (28) includes a ring (36)(38)(40) disposed circumferentially about and having an axis (57) substantially parallel to a central axis (56) of the rotor (28), the ring (36)(38)(40) defining a cavity (45)(46)(47) disposed at a center thereof and having an outer surface (39) supporting at least one row (52) of the plurality of rows (52) of turbine blades (48).

Description

technical field [0001] The present disclosure relates generally to turbomachines, and in particular, the present disclosure relates to turbine rotors. Background technique [0002] Current turbine rotors, such as those used in steam turbines, can be forged from a larger monolithic block into a single large rotor. Other alternative turbine rotors, such as those used in gas turbines, may include an assembly including a plurality of wheels, each wheel including a row of turbine blades representing a stage of the turbine. The wheels can be welded or bolted together. The turbine rotor designs mentioned above result in turbine rotors with relatively high weight and thermal mass. The weight and thermal mass of current rotor designs results in compromised clearance control and prolongs the turbine start-up process promoting rotor temperature and speed changes. Therefore, there is a need in the art to provide a turbine rotor arrangement which overcomes these disadvantages. Conte...
