Conclusions

  1. 1.

    The results obtained from investigations of the first model of the new RRAAB hydraulic machine indicate that application of the proposed principle of structuring the rotor system blades is promising and makes it possible to develop more improved reversible hydraulic machines for future pumped-storage plants.

  2. 2.

    The development of an inlet-outlet section for reversible hydraulic machines with high power indicator and with rigidly secured supplementary blades, the shape of which is selected from the condition of idle deflection in the turbine mode, is possible on the base of a used turbine wheel.
