Abstract
A method is provided for manufacturing a bladed ring for drum-shaped rotors of turbomachinery, especially rotors for axial compressors of gas turbine engines. The bladed ring is to be manufactured by hot isostatic pressing (HIP) and the fiber rings are formed in a metallic powder material for the bladed ring arranged in a circumferential direction. The fiber rings are bonded with spacing therebetween. The fiber rings are reinforced by fibers embedded in a metal matrix. The bladed ring prefabricated in this fashion by HIP is machined down to its required dimensions.
