ABSTRACT:
The invention relates to turbine wheels and in particular an improved way to form the connection between non-metallic turbine wheels and a metallic shaft. The resulting structure provides a secure connection therebetween, reduces tension loads otherwise placed on the non-metallic turbine wheel allowing higher rotational speeds and provides bearing and sealing areas.
