FIELD: aerospace engineering.
SUBSTANCE: invention relates to a method of arranging a working process in a liquid gas generator. Method consists in supply of fuel and oxidant by means of mixing head with use of coaxial centrifugal nozzles at close to stoichiometric ratio of fuel components, liquid-phase mixing of spraying fumes of fuel components, combustion of produced mixture and dilution of combustion products with one of fuel components by its supply through jet nozzles. In compliance with proposed invention, fuel components are supplied through coaxial centrifugal nozzles of external mixing, and diluting component is supplied through jet nozzles belt, located uniformly around coaxial centrifugal nozzles, wherein jet fuel component jets are sprayed with centrifugal atomisation spray sheets after collision thereof and part of component is burnt in flow core, and the remaining part is gasified to bring the ratio of fuel components at the combustion chamber outlet to the predetermined value. Part of the diluting fuel component can be supplied through jet nozzles with formation on the wall of the combustion chamber of the LGG of the first belt near the mixing head, and remaining part—with formation of second belt on combustion chamber wall near outlet from it. Ratio of fuel components of mixing head and first zone of jet nozzles can be close to stoichiometric, and after supply of diluting component of second belt with jet nozzles corresponds to preset one for liquid gas generator.
EFFECT: invention provides for improved quality of mixture formation processes.
