GAS PRESSURE INCREASING METHOD Russian patent published in 2012 - IPC F04F5/04 F02C3/32 

FIELD: engines and pumps.

SUBSTANCE: gas pressure increasing method consists in supply to the gas flow moving through the channel in the gas flow direction of the fluid in quantity of more than 10 percents of gas mass flow. Fluid is under pressure of more than 5 MPa. At that, gas temperature is more than that at which full evaporation of fluid takes place. Kerosene, water or cryogenic fluid can be used as the above mentioned fluid. The above method allows increasing the pressure of gas (mixture) at reduction of its temperature.

EFFECT: method can be used in cooling systems of components of gas turbine engines.
