BALANCE MECHANISM OF COMPRESSOR OF GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide a balance mechanism of a compressor of a gas turbine capable of maintaining rotational balance of the compressor favourable and preventing lowering of efficiency of the compressor. SOLUTION: The rotational balance of the compressor is stabilized by partially cutting a balance land by covering an axis of rotation to continue to a passage wall on the small path side and the inner peripheral side of an annular intake air passage on the upstream side of an impeller vane of the compressor with a housing and providing the unnular balance land on the axis of rotation in the housing.
