Abstract: A locking blade for a rotor can include an airfoil portion with a root from which a tongue extends. Opposed bucket segments can engage the tongue and can be retained in a longitudinal direction of the blade by a fastener, such as a pin, that can extend through holes in the segments and tongue. Tines parallel to and on opposite sides of the tongue can extend from the root and include holes through which the fastener can extend, the bucket segments extending between respective tines and the tongue. The structure can eliminate an assembly gate in a rotor.
Abstract translation: 用于转子的锁定刀片可以包括具有舌部的根部的翼型部分。 相对的铲斗段可以接合舌部并且可以通过诸如销的紧固件保持在刀片的纵向方向上，该紧固件可以延伸穿过节段和舌头中的孔。 舌头平行于舌片和相对侧上的齿可以从根部延伸，并且包括紧固件可以延伸穿过的孔，铲斗段在相应的尖齿和舌部之间延伸。 该结构可以消除转子中的组装门。

Abstract: A steam turbine is provided. The steam turbine includes a housing, a first steam inlet configured to discharge a first steam flow within the housing, and a second steam inlet configured to provide a second steam flow. A rotor and stator are coupled to the housing and configured to form a first flow path therebetween and in flow communication with the first steam flow. The rotor includes a plurality of blades coupled to the rotor, at least one root of the plurality of blades has a first side, a second side and a passageway coupled in flow communication to the first side and the second side. The passageway is configured to receive the second steam flow within the at least one root. The at least one root includes an angel wing configured to seal the second steam flow from the first flow path.
