AIR-COOLED STATOR BLADE OF GAS TURBINE

摘要

PURPOSE: To prevent generation of thermal stress in the root part of a stay for forming cavities in a blade in an air-cooled stator blade of a gas turbine. ;CONSTITUTION: A stay 14 in the direction of height of a blade for partitioning the interior of the blade into plural cavities is provided with a slit 15 extended over the whole length in the direction of height for cutting the stay 14, a groove 16 is provided in the part opposite to the slit 15 of the stay 14, and an inner plate 17 is inserted in the groove 16 to form plural cavities in the interior of the blade, so that thermal deformation of the stay 14 and the blade part 7 is not constrained by the inner plate 17.;COPYRIGHT: (C)1996,JPO
