GAS-HYDRAULIC TURBOMACHINE Russian patent published in 2006 - IPC F01C7/00 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in stream and gas-turbine engines, compressors, internal combustion engines and pumps. Proposed gas-hydraulic turbomachine contains sealed housing with fitted-in radial turbine with possibility of rotation, and sealings for instance, labyrinth sealings and fuel feed and ignition systems. Turbine wheel of radial turbine is installed in housing with calibrated clearance and is provided with radial blades. Crescent-shaped guide-vane assemblies filled with liquid adjoin the housing from outer side of cylindrical wall. Each crescent-shaped guide-vane assembly contains bell outlet and nozzle assembly arranged after guide-vane assembly in direction of rotation of turbine wheel. Bell outlet and nozzle assembly are formed by holes in cylindrical wall of housing between turbine interblade channels. Turbine wheel contains two side disks with radial blades fitted in between. Radial blades are curved over periphery to side opposite to rotation of turbine wheel forming interblade channels. Said channels are made for periodical complete or partial removal of liquid at rotation of turbine wheel. Holes are made in one or both side disks from side of turbine shaft opening at one side to distributor, and at other side to interblade channels. Part of cylindrical wall of housing between outlet and nozzle, in direction of rotation of turbine wheel, overlaps at least one interblade channel of turbine. Part of cylindrical wall of housing between nozzle and outlet, in direction of rotation of turbine wheel, also overlaps at least one interblade channel of turbine.

EFFECT: improved reliability, increased specific power and efficiency of turbomachine.
