Abstract: A turbomachine blade may include an airfoil and a shank coupled to the airfoil. The shank may include a cover plate having a first circumferential face and a second, opposing circumferential face. A radial cooling groove is positioned in the first circumferential face and is configured to allow a cooling fluid to pass from a first radial position to a second, different radial position relative to the platform. The radial cooling groove provides cover plate and shank cooling. In addition, the radial cooling groove may deliver fluid for purging gaps between blade platforms and cover plates, which prevents the ingestion of hot gas from the turbine flowpath.

Abstract: A seal configuration includes a housing and a rotatable member rotationally mounted relative to the housing. The rotatable member has at least one portion defining an outer perimetrical face that is configured to contact the housing during operational conditions that cause a radial dimension of the at least one portion to increase. The at least one portion has opposing axial surfaces with each of the opposing axial surfaces being dimensionally axially nearer to the other of the opposing axial surfaces immediately radially inwardly of the outer perimetrical face than a furthest part of the outer perimetrical face.
Abstract translation: 密封构造包括壳体和相对于壳体旋转地安装的可旋转构件。 可旋转构件具有限定外周面的至少一个部分，其构造成在导致至少一个部分的径向尺寸增加的操作条件期间接触壳体。 所述至少一个部分具有相对的轴向表面，其中每个相对的轴向表面的尺寸轴向更靠近所述外圆周表面的径向向内的所述相对的轴向表面中的另一个，而不是所述外周边面的最远部分。
