The invention refers to the field of wind power engineering, particularly to the vertical axis rotor-type wind turbines, which can be used for drive of electric generators or other using equipment of mechanical energy. The rotor-type wind turbine contains a central vertical shaft, mounted in a hollow elongated supporting column, and rotor structure, comprising two lattice-type blocks with power elements—the lattice-type stacks of aerodynamic blades. Each of the lattice-type blocks is carried by two corresponding lattice-type arms. When using the wind turbine two-block structure, the blocks are positioned by 180° to each other. The end parts of the aerodynamic lattice-type blades in blade blocks are fastened in relevant upper and lower shroud flanges. Each blade block forms the lattice and inter-blade channels so that the efficiency of utilization of the energy of the wind blowing along the inter-blade channels is determined as the sum of thermodynamic component and kinetic component of the factor of utilization kinetic energy of wind. Moreover, the design of vertical-axis wind turbine provided with lattice-type blade blocks and inter-blade channels ensure the rotation of the rotor under the impact of air flux even at low wind velocities.
