Rotor for a rotating thermal engine as well as manufacturing method for such a rotor

摘要

The rotor (30) consists of several forged pieces (31, 32) in axial succession, set against each other and firmly joined to each other. These pieces consist of materials differing in their thermal load capacity, such as high-tensile steel and a nickel-based alloy. The forged pieces are joined to each other by bolts (36) and nuts (37).
