COMPRESSOR AND ASSOCIATED GAS TURBINE

摘要

The invention relates to an axial compressor (10) comprising an annular flow channel (36), in which adjustable blades (14) of a blade ring that extend through the flow channel (36) are rotatably mounted, each blade (14) having a lug (26) on the rotor-side of the vane (16) for mounting an inner ring (32). In order to provide a wear-free, self-centring inner ring (32), the ring is designed as a split ring with two opposing ends (44) and a spring element (52) for spreading the split ring.
