  • Coolable stator structure for a gas turbine engine
    Patent number: 4721433
    Abstract: A stator assembly 16 for a gas turbine is disclosed. Various construction details which increase the effectiveness of the use of cooling fluid are developed enabling the use of stator vanes which do not have blockable holes for cooling air. In one embodiment, a segmented seal ring extends circumferentially between an array of coolable stator vanes 34 and a casing 22 to block the vane cooling air from convectively transfering heat to the casing.
