The article describes the design and analysis of a small-size hydro turbine with a cardinally new structural diagram for hole drilling. Unlike the conventional bottom-hole hydraulic motors, the proposed design involves inversion of motion of the structural components—the stator rotates around the immobile rotor, which enables an essential increase in the energy efficiency of power fluid. The research used the methods of inversion, linking and generality to optimize the structure of the hydro turbine. In terms of a six-sector hydro turbine with a diameter of 196 m, the energy performance of the machine is calculated as function of the drilling length, fluID flow rate and fluID flow angle. The developed hydro turbine is an effective, small-sized and economically expedient solution for the long-hole drilling practice, which opens prospects for the further experimental validation and introduction of the machine.
