FIELD: mechanical engineering; gas turbine engines.

SUBSTANCE: methanol (liquid hydrogen or methane) after pump is gasified at temperature of 250 C into mixture of gases H2 and CO by using waste heat after main turbine in turbocompressor heat exchanger in endothermic reaction in presence of catalytic agent. Gas mixture is delivered to additional turbine mechanically coupled with additional compressor. Gases and air after turbine and compressor at ratio close to stoichiometric ratio, get into combustion chamber made in form of space of ejector nozzle, low pressure inlet branch of which being coupled with outlet of main compressor the, the same as inlet of additional compressor, and outlet is connected to inlet of main turbine. part of gas mixture after additional turbine gets to inlet of main turbine and on main turbine hollow blades on front edges of which slots are made to pass mixture into gas-air duct of main turbine. Water nozzles can be installed at inlet of main compressor. To obtain mechanical energy in form of kinetic energy of reactive stream engine can be furnished with housing to form second circuit of ejector type and reactive nozzle, with ejector nozzle of outer circuit being installed between outlet of main turbine and inlet of turbocompressor. Space of ejector nozzle of outer circuit can be made in form of afterburner with nozzles connected to outlet of additional turbine.

EFFECT: enlarged operating capabilities.
