FIELD: engines and pumps.
SUBSTANCE: fixed clamp ring is installed around gas window for passage of gas turbine hot gases; moreover, specified clamp ring is surrounded with fixed annular cavity that represents annular cooling chamber, to which at least one inlet opening of cooling air exits; besides, specified clamp ring consists of multiple annular segments, every of which comprises internal system of upper cooling and internal system of lower cooling, besides, specified internal system of lower cooling remains independent from specified system of upper cooling and is radially displaced relative to specified system of upper cooling.
EFFECT: development of efficient system of gas turbine ring cooling.
