Abstract

1332935 Casting composite turbine rotors C A V Ltd 19 April 1971 [14 April 1970] 17560/70 Heading B3F [Also in Division F1] A turbine rotor is constructed by assembling ceramic blades, e.g. of silicon nitride, in a jig and then casting the rotor hub around the blade roots by the lost wax process so that the roots are subjected to compression when the hub metal, e.g. nickel alloy, solidifies.
