METHOD FOR STABILIZING THE COMBUSTION PROCESS IN THE COMBUSTION CHAMBER OF AN AIRCRAFT ENGINE Russian patent published in 2022 - IPC F02K9/00 B82Y99/00 

FIELD: engine technology.

SUBSTANCE: invention relates to engine technology, namely to a method for stabilizing the combustion process in the combustion chamber of an aircraft engine and can be used in modern aircraft engines with high-speed airflow to improve emission characteristics and expand the range of stable operation of the combustion chamber, including to improve the high-altitude engine start. The method consists in the creation of vortex zones in the combustion chamber, the supply of the main liquid hydrocarbon fuel and the preliminary creation of auxiliary fuel, including its gasification and supply to the vortex zones. In this case, auxiliary fuel is used in the form of a colloidal solution of aluminum nanoparticles of a certain size, the concentration of which ensures the agglomeration of aluminum nanoparticles and is at least 2.5 wt. % and gasification of auxiliary fuel is carried out during its supply to the vortex zones of the combustion chamber.

EFFECT: creating a method for stabilizing the combustion process in the combustion chamber of an aircraft engine, providing feedback between the vortex zones and the main combustion zone in the combustion chamber due to the absorption of thermal radiation by aluminum agglomerates from combustion products in the main combustion zone of the combustion chamber.
