Definitions

the object of this invention is therefore construction of a ceramic turbine wheel, which, although it has a sufficient high temperature strength, does not show the above described difficulties in production.
the transition from the conical hub portion to the body is rounded with a radius of at least 20% of the diameter of the hub portion.
