FROTHING AERODYNAMIC SYSTEM OF INJECTION OF THE AIR-FUEL MIXTURE INTO THE COMBUSTION CHAMBER OF THE TURBOMACHINE, THE TURBOMACHINE COMBUSTION CHAMBER AND THE TURBOMACHINE Russian patent published in 2007 - IPC F23D11/10 F23R3/28 F02C7/22 

FIELD: aircraft industry; other industries; systems of injecting of the air-fuel mixture into the combustion chambers.

SUBSTANCE: the invention is pertaining to the systems of injection of the air-fuel mixtures into the combustion chambers. The invention presents the aerodynamic system (2) of injection of the air-fuel mixture into the turbomachine combustion chamber containing: the tubular structure (4) with the shaft XX' open at the lower streamwise end (4b)for feeding of the air-fuel mixture; at least, one channel (6) of the air feeding, which is open into the structure(4) for feeding in it of the air under pressure Р_A; the annular fuel passage (8) formed into the structure (4) around its axis XX', connected with at least one channel(10) the fuel feeding, in which the fuel is running under pressure Рс, and open on the lower streamwise end (8b) into the structure (4), and the tool for injection of the gas injection in, at least, one channel(10)of the fuel feeding. At that the gas is under pressure Р_G , which exceeds the pressure Р_A and is greater than or equal to pressure Р_С used for foaming of the fuel being fed into the structure. The invention ensures optimization of the time used for spraying of the fuel and its evaporation.

EFFECT: the invention ensures optimization of the time used for spraying of the fuel and its evaporation.
