GAS TURBINE WITH REGENERATION OF HEAT Russian patent published in 2002 - IPC

FIELD: mechanical engineering; gas turbine engines. SUBSTANCE: proposed gas turbine engine with regeneration of heat has compressor, combustion chamber, high pressure turbine, power gas turbine and gas-to-air heat exchanger and additional compressor. Compressor is installed on one shaft with power air turbine. Inlet of air turbine is coupled with outlet of additional compressor through air space of heat exchanger. Gas space of heat exchanger is connected with outlet of power gas turbine. Ratio of area of passage of additional compressor at inlet to area of passage of additional compressor at outlet is 2-5. Ratio of area of neck of first nozzle assembly of power air turbine to area of neck of first nozzle assembly of gas turbine is 0.5-1. EFFECT: increased economy and power output of engine. 3 cl, 3 dwg
