STATIONARY BLADE CASCADE OF AXIAL COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To considerably reduce a vibrational stress due to resonance in all vibration mode in an operation region of an axial compressor, and prevent performance reduction of an entire stationary blade cascade.;SOLUTION: In the stationary blade cascade of this axial compressor in which a plurality of stationary blades 2 are arranged over an entire periphery in a peripheral direction, each pitch between the stationary blades constituting the stationary blade cascade periodically varies in the peripheral direction.;COPYRIGHT: (C)2005,JPO&NCIPI
