FIELD: gas-turbine engines.
SUBSTANCE: proposed gas-turbine engine combustion chamber has external and internal annular load-bearing casings joined together by means of posts with butt-end flanges. It also has non-split diffuser. Butt-end flanges are manufactured by mechanical treatment to form facets whose beveled part is tilted through 30-40 deg. to post axis. At least one third of posts has fastenings for securing combustion-chamber flame tube to them.
EFFECT: enhanced reliability and service life, reduced mass and size of combustion chamber.
