    摘要： A rotor disk includes a rim with axially spaced apart forward and aft ends, with the aft end having a larger diameter than the forward end. The rim includes a plurality of straight dovetail slots defining dovetail posts therebetween. Each dovetail post includes a pair of lobes, a neck, and first and second pressure faces facing radially inwardly from the lobes. The first and second pressure faces vary in radial height therebetween from a first magnitude at the rim aft end to a second and smaller magnitude at the rim forward end to shift a portion of the bending loads from the dovetail post at the rim forward end to the dovetail post at the larger rim aft end.

    摘要： A rotor blade for a turbine engine including a blade root section and an airfoil section which extends radially outward along a radial line RAS from the blade root section, is described. The radial line RAS extends at an angle relative to a plane extending across a top surface of the platform, rather than normal, or perpendicular, to such plane. As a result, and during a blade out event, an over turning moment is generated in a root of the airfoil section. The overturning moment facilitates bending the airfoil section reducing damage to the stator.

    摘要： The present invention relieves the stress at a fillet of a blade shank using at least one axially extending pocket on the shank near an axially extending fillet of a shank to root interface or a shank to platform interface on a pressure or suction side of the blade and the pocket is axially shorter than the fillet. The stress relief pocket has a radially extending pocket width that is substantially wider than a fillet width between generally axially extending edges of the fillet wherein the pocket width may be several times wider than the fillet width. The wider pocket shields the fillet thereby reducing the stress concentration at the fillet.

    摘要翻译： 本发明使用刀柄上的至少一个轴向延伸的口袋靠近刀柄的轴向延伸圆角至叶片的根部界面或柄与柄与平台界面之间在叶片的压力或吸力侧接近而减轻叶片柄部的应力，并且 口袋的轴向短于圆角。 应力释放袋具有径向延伸的袋宽度，其宽度大大大大于圆角的大致轴向延伸的边缘之间的圆角宽度，其中袋宽可以比圆角宽度多数倍。 更宽的口袋可以防护圆角，从而减少鱼片上的应力集中。
