FIELD: mechanical engineering; gas-turbine engines.
SUBSTANCE: proposed combustion chamber of gas-turbine engine has diffuser, housing and fire tube at inlet of which antechamber is installed. Antechamber inlet communicates with inlet if diffuser though at least one acoustic waveguide made with due account of dependence protected by invention.
EFFECT: suppression of pressure and speed fluctuations of gas appearing in combustion chamber at vibratory combustion.
