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.
