AIR-JET ENGINE Russian patent published in 2015 - IPC F02K7/16 

FIELD: engines and pumps.

SUBSTANCE: air-jet engine contains an air intake, a casing, a compressor with a compressor rotor, and a combustion chamber, a gas turbine, a shaft connecting the compressor and the gas turbine, and a jet nozzle. After the compressor an air channel is made, in it a first hydrogen-air heat exchanger is installed. Inside the air channel coaxially with the shaft the hydrogen turbine is installed, it has input and output headers. The input header is connected with the heat exchanger output, and the output header is connected with the combustion chamber. After the air channel a MP compressor and a HP compressor are installed, between them the second hydrogen-air heat exchanger is installed. Before the gas turbine the HP gas turbine is installed. The hydrogen turbine and MP compressor are connected by the second shaft, installed coaxially with the first shaft, and the HP compressor is connected with the HP turbine by the third shaft.

EFFECT: invention increases energetic capacities of the gas-turbine engine, improves the compression ratio of the compressor, thrust force of the engine and improves its specific characteristics.
