Abstract: A blade is mountable to a disc. The blade comprises a blade platform and a blade root extending from the blade platform. The blade root comprises a first hook and a second hook, a first neck between the first hook and the blade platform, and a second neck between the first hook and the second hook. Each hook comprises a contact surface and a non-contact surface. An angle between each contact surface and each non-contact surface is optimized to reduce local stresses.
Abstract translation: 刀片可安装到盘上。 叶片包括从叶片平台延伸的叶片平台和叶片根部。 叶片根部包括第一钩和第二钩，第一钩和叶片平台之间的第一颈部以及第一钩和第二钩之间的第二颈部。 每个钩包括接触表面和非接触表面。 每个接触表面和每个非接触表面之间的角度被优化以减少局部应力。

Abstract: A rotating blade for a steam turbine includes a root section and an airfoil section contiguous with the root section. The airfoil section is shaped to optimize aerodynamic performance while providing optimized flow distribution and minimal centrifugal and bending stresses. The blade also includes a tip section continuous with the airfoil section, and a cover formed as part of the tip section. The cover defines a radial seal that serves to minimize tip losses. The rotating blade is capable of running at operating speeds between 5626 and 11250 rotations per minute.
Abstract translation: 用于蒸汽轮机的旋转叶片包括根部和与根部相邻的翼型部。 翼型部分成形为优化空气动力性能，同时提供优化的流量分布和最小的离心和弯曲应力。 叶片还包括与翼型部分连续的尖端部分和形成为尖端部分的一部分的盖。 盖子限定了径向密封，其用于最小化尖端损失。 旋转叶片能够以每分钟5626到11250转之间的运行速度运行。

Abstract: Vapour turbine operating with geothermal vapours containing corrosive agents such as chlorides and/or sulfides in particular. The turbine comprises a series of rotor blades made of a nickel alloy containing a quantity of nickel ranging from 55% to 59% by weight to avoid the washing of the geothermal vapours, maintaining a high useful life of the series of rotor blades and vapour turbine.
Abstract translation: 特别是含有腐蚀性物质（如氯化物和/或硫化物）的地热蒸气运行的汽轮机。 涡轮机包括一系列由镍合金制成的转子叶片，其包含一定量的镍，重量百分比为55％至59％，以避免地热蒸气的洗涤，保持一系列转子叶片和蒸汽涡轮机的高使用寿命 。
