GAS TURBINE DRIVE OF ELECTRIC GENERATOR Russian patent published in 2009 - IPC F01D15/10 F02C7/143 

FIELD: engines and pump.

SUBSTANCE: proposed drive represents one straight-through gas turbine engine comprising axial supersonic high-pressure compressor, center support, turbo-expander with heat-and-mass exchange apparatus and starting manifold, two-zone combustion chamber, staged and free turbines and steam generator. Free turbine communicates with intermediate shaft to make electric generator drive. Steam generator is made integral with turbine guide vanes. Four-stage compressor is coupled, via step-up gear, with turbine intermediate shaft. To cool incoming air to cryogenic temperature (minus 120°C), compressor inlet accommodates liquid neon heat exchanger with vacuum chamber and liquid hydrogen heat exchanger with vacuum chamber that communicates, via cracker, with combustion chamber. Turbo-expander with radial-axial centripetal stage loading device is mounted ahead of combustion chamber. Outside turbo-expander housing, heat exchanger is arranged incorporating control units and communicating, via pipeline, with turbo-expander and, separately, with each compressor stage. Impulse-reaction five-stage turbine is mounted on rear and front supports. Ball-shaped second steam generator is mounted behind the turbine, along the engine axis, furnished with microwave heater to heat water to steam generation temperature connected, via control elements, with turbo-expander starting manifold. Hot hard coal accumulator and combustible (carbon oxygen hydroxides) accumulator is mounted behind the turbine to communicate with combustion chamber second zone fuel manifold. Ball-shaped second steam, hot hard coal accumulator and combustible (carbon oxygen hydroxides) accumulator are arranged successively.

EFFECT: higher efficiency, output and reduced heat capacity.
