| 发明名称 | Method of producing a guide vane | ||
| 摘要 | The invention relates to a method of producing a guide vane, the method comprising a step of fabricating at least a portion of a metal body of the guide vane by additive fabrication, with at least one outside surface thereof presenting a plurality of cavities; and a step of filling said cavities with a material of lower density than the metal body in order to form at least one substantially smooth airfoil surface. | ||

| 主权项 | 1. A production method of producing a guide vane, the method comprising: fabricating at least a portion of a metal body of the guide vane by additive fabrication, the metal body including a metal frame surrounding a cellular core including at least one outside surface presenting a plurality of cavities opening to at least one of a suction side or a pressure side of the guide vane; placing the metal body in a mold; filling said cavities with a synthetic material of lower density than the metal body in order to form at least one substantially smooth airfoil surface on at least one of the suction side or the pressure side of the guide vane; and removing the metal body from the mold after the synthetic material has hardened. | ||
