AXIAL GAS TURBINE Russian patent published in 2015 - IPC F01D5/08 F01D5/22 F01D25/12 

FIELD: machine building.

SUBSTANCE: axial gas turbine contains a rotor with alternating rows of air-cooled rotor blades and rotor heat shields, and the stator with alternating rows of air-cooled guide vanes and air-cooled heat shields of the stator installed in the holder of the guide vanes. The stator coaxially encloses the rotor outside with formation of the path of hot gases flow between them so that the rows of rotor blades and heat shields of the stator and rows of the guide vanes and rotor heat shields are located with reference to each other in a specific manner respectively. The rows of the guide vanes and the next row of rotor blades downstream form a turbine stage. The turbine stage is fitted with devices for recycling of the cooling air already used for cooling, in particular, of profile parts of the guiding turbine stage blades, for the purpose of cooling of the stator heat shields of the named turbine stage downstream the named guide vanes.

EFFECT: invention is aimed at improvement of cooling efficiency and minimising of cooling air consumption.
