METHOD OF DETERMINATION OF BOUNDARIES OF VIBRATORY COMBUSTION OF COMBUSTION CHAMBER AND DEVICE FOR REALIZATION OF THIS METHOD

摘要

FIELD: manufacture of combustion chambers for power plants, mainly aircraft engines. SUBSTANCE: proposed method includes placing the combustion chamber in working mode followed by measuring relative rate of flow in chamber at each noted consumption of fuel by increasing and decreasing area of nozzle section till regular pressure fluctuations are obtained. Proposed device is provided with control system for regulation of boundaries of vibratory combustion in combustion chamber. EFFECT: extended field of application; low cost; reduction of time for determination of combustion boundaries. 4 cl, 3 dwg
