    • A rotor blade is provided that includes a root, a hollow airfoil, and a conduit disposed within the root. The hollow airfoil has a cavity defined by a suction side wall, a pressure side wall, a leading edge, a trailing edge, a base, and a tip. An internal passage configuration is disposed within the cavity. The configuration includes a first radial passage, a second radial passage, a rib disposed between and separating the first radial passage and second radial passage, a plurality of crossover apertures disposed within the rib, and a plurality of trip strips disposed within the second radial passage. The trip strips are attached to an interior surface of one or both of the pressure side wall and the suction side wall. The trip strips are disposed within the first radial passage at an angle α that is skewed relative to a cooling airflow direction within the first radial passage, and positioned such that each of the plurality of trip strips converges toward the rib. The rib end of at least a portion of the plurality of trip strips is located between a pair of adjacent crossover apertures. The conduit is operable to permit airflow through the root and into the first passage.
    • 提供了一种转子叶片,其包括根部,中空翼片和设置在根部内的导管。 中空翼片具有由吸力侧壁,压力侧壁,前缘,后缘,底座和尖端限定的空腔。 内部通道构造设置在空腔内。 该构造包括第一径向通道,第二径向通道,设置在第一径向通道和第二径向通道之间并分离第一径向通道和第二径向通道的肋,布置在肋内的多个交叉孔,以及设置在第二径向通道内的多个跳闸带 。 脱扣带附接到压力侧壁和吸力侧壁中的一个或两个的内表面。 跳闸条以第一径向通道内的相对于冷却风向倾斜的角度α设置在第一径向通道内,并且定位成使得多个跳闸带中的每一个朝向肋收敛。 多个跳闸带的至少一部分的肋端部位于一对相邻的交叉孔之间。 管道可操作以允许气流通过根部并进入第一通道。
