Composite ceramic turbine rotor

A turbine rotor, comprising a hub or center section and an outer blade section integrally attached to the hub section, both sections being composed of a ceramic refractory material. The hub section possesses a high degree of mechanical strength, which normally requires that it have a specific gravit...

Beschreibung
Zusammenfassung:	A turbine rotor, comprising a hub or center section and an outer blade section integrally attached to the hub section, both sections being composed of a ceramic refractory material. The hub section possesses a high degree of mechanical strength, which normally requires that it have a specific gravity close to the theoretical specific gravity of the ceramic material used. The blade section of the rotor, which is permanently bonded to the hub, is composed of the same ceramic material as the hub section but of lower strength and lower density. The effect of the latter is relative ease of fabrication and reduced stresses on the hub section when attached thereto.
