METHOD FOR GAS GENERATION AND ENGINES (EMBODIMENTS) Russian patent published in 2023 - IPC F02C5/12 F02B33/00 

FIELD: gas turbine engines.

SUBSTANCE: gas generation method is implemented in an engine containing a turbine, a compressor, two combustion chambers (CC) and a cylinder with a freely moving piston. During the working stroke in the first CC, the burnt mixture is pumped into the turbine and into the cylinder. The piston, moving, compresses and forces air from the second half of the cylinder into the second CC, where it is then held. The first CC and cylinder are purged, the exit from the cylinder is locked, the first CC and cylinder are filled with compressor air, and the working stroke in the second compressor is implemented in a similar way. The gas turbine engine operating according to the proposed method contains a compressor, a turbine, two combustion chambers, a cylinder with a freely moving piston, the length of which is equal to half the cylinder. The cylinder's outer terminals are connected to the combustion chambers through locking devices (LDs), and its central terminal is connected to the turbine through an LD. During the working stroke in the first CC, the gas flow is injected into the turbine and into the cylinder, displacing air from there into the second CC, which is closed and the air is kept. After exhaust, the first CC and the free part of the cylinder are purged, filled with air and kept there. The working stroke in the second CC is implemented in a similar way. According to another embodiment, the gas turbine engine operating according to the proposed method contains a compressor, two turbines, two compressor stations and a channel in which a freely moving piston can be installed, the ends of the channel are connected through locking devices, respectively, to the left compressor station and the left turbine, as well as to the right compressor station and with the right turbine. During the power stroke, the burnt mixture from the first CC is injected into the first turbine and into the air channel, the air is compressed and displaced into the second CC, which is closed, and the air is kept. The first CC and the channel are blown and filled with air which is kept there. The working stroke in the second CC is implemented in a similar way.

EFFECT: objective of the invention is to develop a method for generating gases and engine circuits operating according to this method, containing a minimum number of moving parts
