COOLING UNIT OF JET ENGINE Russian patent published in 2009 - IPC F02K9/64 F02K7/10 

FIELD: mechanical engineering.

SUBSTANCE: invention elates to mechanical engineering, particularly to construction of turbojet engines and can be used in jet engine, chiefly by Cheremushkin O.V. For cooling process implementation (operation) of jet engine with implemented cooling main of movements: fuel; oxidants, - mutually adding and changing to each other, in the form of oxygen and atmospheric stream, as cooling agent and fuel components, and also implemented vaporescent mains of jet engine, for cooling of external wall of chamber, water fractions, in the form of high-temperature vapor, feeding into the combustion chamber through changeable external and internal shaped insertion, and also changeable shapes annular bottom with cooled fuel pull-out spark plugs, and also it is implemented bleed system of gas stream from combustion chamber, for work implementation of preliminary evaporator of jet engine and cooling, cooled gas stream, gas turbine blades of jet engine. Additionally for controlling of cooling process (operation) of jet engine, it is implemented electric circuit of aircraft, feeding of cooling agents through the execution unit into jet engine: evaporator of oxygen, with system of pre-running mode of jet engine; ratio oxidant controller with system of forced passage, for feeding into jet engine of oxygen; fuel air distributor with proportion of fuel and water supplying into jet engine, and also it is implemented electric circuit of jet engine, controlling of execution units of providing of its operation, through: electromagnetic supplying taps into jet engine of fuel and oxidants; thermal switch to the water supply system, into vaporescent mains of jet engine, and also blowing off systems of vaporescent mains of jet engine, after its turning off, by ambient air, and oxidant (oxygen).

EFFECT: invention provides cooling effectiveness increase.
