Verdichter in mehrstufiger Axialbauart

摘要

Compressor comprises a cantilevered rotor (7) having several moving blade rings (4-6) on interconnected disk- and/or ring-shaped blade supports (11-13). At least one (12, 13) of the rotating blade supports is designed as a metal matrix composite, i.e. an at least partly fiber-reinforced metal component. The pivot bearing (18) absorbing at least the majority of the radial loads exerted on the rotor has a pre-determined breaking point (19) which, on exceeding a defined radial load, allows limited radial yielding of the rotor with subsequent contact with the stator (2) to reduce the speed, optionally to a complete stop. Preferred Features: The blade support has in the fiber-reinforced region (14-16) a metal matrix, preferably based on titanium, and at least one long fiber of silicon carbide arranged in windings.
