摘要： A method for manufacturing a component of a rotating machine comprises the steps of forming a structural inner portion by additive manufacturing from a first material; covering the structural inner portion with a protective outer portion made of a second material; the first material has a melting point higher than a second material.

摘要： A turbine, and particularly a low pressure turbine is disclosed, which comprises a plurality of rotor members and spacers for arranged between rotor members, to avoid that an ingested gas flow from the hot gas flow path channel reaches the wheel space. The rotor members each include a deflector. The deflector is placed in correspondence with each spacer and deflects the ingested gas flow over the upper surface of the spacer, thus preventing it to heat up the roots of the blades.
