FIELD: energy.
SUBSTANCE: combustion chamber with an adjustable opening to supply cooling air for micro gas turbine engine includes a housing, flame tube and fuel injection assembly; flame tube is arranged inside the housing and located along the axis of the combustion chamber, wherein there is an air case annular ring, end flange, between the housing of the combustion chamber and fire tube. End flange is screwed into the housing of the combustion chamber to adjust the required amount of air in the flame tube.
EFFECT: invention ensures accurate adjustment of air flows in the combustion chamber in a wider range of engine operation modes, and also enables operation using different types of fuel due to occurence of different parameters of mixture formation.
