Abstract

The structural of pilot one-piece bimetallic blisks for high temperature gas turbine with Ni-base super alloys blades and powder disk part are designed. The model equipment for connection uncooled and cooled blades with disk part by hot isostatic pressing technology (HIP) are offered. Plan of technological process is described. A strength calculation analysis of blisks is carried out.
