PULSE GAS-TURBINE ENGINE (VERSIONS) Russian patent published in 2009 - IPC F02K7/02 

FIELD: engines and pumps.

SUBSTANCE: pulse gas-turbine engine comprises pulse gas-generator engine connected to compressor, and also to additional gas turbine or to jet engine nozzle. Engine also comprises gas-generator turbine having at least two combustion chambers, which are arranged with the possibility of rotation parallel to shaft, on one side, comprising inlet openings that exit for instance to distributor with ignition, control and monitoring devices, with systems of fuel or fuel-air mixture, air supply. Combustion chambers are joined to distributor with calibrated gap and, for instance, labyrinth seals. On the other side, combustion chambers comprises nozzles, for instance, in the shape of Laval nozzles arranged in the form of vanes bent aside opposite to rotation, coming out in axial direction to at least one crescent guide apparatus. Nozzle apparatus is arranged with clearance to nozzles of combustion chambers, along circumference of their rotation so that it comprises, at first along with nozzles rotation, bleed, and then nozzle apparatus that comes out to nozzles of combustion chamber. Between bleed and nozzle apparatus there is cutoff plate arranged with the possibility to cover nozzle of at least one combustion chamber. Between nozzle apparatus and bleed of crescent guide apparatus, along with rotation of combustion chamber nozzles, cutoff plate is also arranged, with the possibility to close nozzle of at least one combustion chamber during its rotation. In every crescent guide apparatus there is hole provided, which is connected to exhaust branch pipe coming out to nozzles, for instance, controlled, of additional gas turbine, or to nozzle, for instance, controlled, of jet engine.

EFFECT: invention increases reliability and efficiency factor of engine.
