Abstract: A turbine blisk is provided. The turbine blisk includes an inner rim, a plurality of adjacent rotor blades extending radially outward from said inner rim, a shroud segment integrally coupled to each of the plurality of adjacent rotor blades, thereby forming a plurality of adjacent shroud segments, and a gap defined between each of the adjacent shroud segments. The gap has a geometry that facilitates interlocking the plurality of adjacent shroud segments when a torsional force is applied to the plurality of adjacent rotor blades.

Abstract: A system and method for producing liquid natural gas (LNG) from a natural gas stream is presented. The system includes a moisture removal device and compressor for removing moisture from and compressing the natural gas stream. The low moisture compressed natural gas stream is cooled in a heat exchanger to discharge a cooled compressed discharge stream. A multi-phase turbo expander provides for further cooling and expansion of the cooled compressed discharge stream, generating an expanded exhaust stream comprising a mixture of a vapor comprised substantially of CH 4 and a LNG/ice/solid CO 2 slurry. The expanded exhaust stream is separated to generate a vapor stream comprised substantially of CH4 and a liquid natural gas/ice/solid CO 2 slurry stream. Further separation of the liquid natural gas/ice/solid CO 2 slurry stream generates a liquid natural gas output stream and an output stream comprised substantially of ice/solid CO 2 .

Abstract: A supersonic compressor (10) includes a fluid inlet (26), a fluid outlet (28), and a fluid conduit extending there between with a supersonic compressor rotor (40) disposed therein. The supersonic compressor rotor includes a first end wall (60) and a plurality of vanes ( 46) coupled thereto. Each pair of the vanes defines a fluid flow channel (80). The fluid flow channel defines a flow channel inlet opening (76) and a flow channel outlet opening (78) and includes a throat portion (124). The supersonic compressor rotor also includes a second end wall (90) and at least one axially translatable fluid control device (172) positioned adjacent to the rotor. The axially translatable fluid control device is configured to obstruct the throat portion and includes at least one axially translatable protrusion (178) insertable into at least a portion of the throat portion.
