  • Axial flow hydraulic turbine with fixed blades bolted-on
    Patent number: 8419369
    Abstract: A hydraulic turbine has a runner blade bolted to a hollow runner hub. The runner blade has a flange that mates with a corresponding recess on the hub. Bolting connections pass through complementary array like patterns of apertures spread across and in the hub and blade flange to attach the blades to the hub.

  • Axial flow hydraulic turbine with blade mounting
    Patent number: 8235669
    Abstract: A hydraulic turbine has a runner blade fixedly mounted to a runner hub. The runner blade has a mounting flange having a generally rectangular shape held in contact with a complementary generally rectangular shaped outside surface portion of the runner hub. The complementary rectangular shapes increases surface contact area between the blade mounting flange and the hub over that of circular shaped flanges and thereby reduces the stress levels between the blade flange and the hub. Further, the surface contact area between the blade mounting flange and the blade root is increased to thereby reduce the stress level in the blade root fillets.
