Summary:To provide a turbine rotor blade with many additively manufactured, integral features.SOLUTION: A turbine rotor blade root (144) is additively manufactured and includes a shank (148) having a radially extending chamber defined therein. A blade mount (146) is at a radial inner end of the shank. The blade mount (146) has a hollow interior (330) defined therein with the hollow interior (330) in fluid communication with the radially extending chamber. A lattice support structure (340) is disposed within the hollow interior (330) of the blade mount (146).SELECTED DRAWING: Figure 25 【課題】多数の付加製造された一体型特徴を備えたタービンロータブレードを提供する。【解決手段】タービンロータブレード根元（１４４）は、付加製造され、内部に画定された半径方向に延びるチャンバを有するシャンク（１４８）を含む。ブレードマウント（１４６）は、シャンクの半径方向内側端にある。ブレードマウント（１４６）は、内部に画定された中空内部（３３０）を有し、中空内部（３３０）は、半径方向に延びるチャンバと流体連通する。格子支持構造（３４０）は、ブレードマウント（１４６）の中空内部（３３０）内に配置される。【選択図】図２５
