NOVELTY - The turbine (1) has a set of traverses (5) extending from a shaft (2) and each of multiple hydrofoil profile blades (3, 3a-3d) fixed on the shaft by the traverses. Each blade forms a layer (21a) with another set of traverses (5a, 5b), where the latter traverses are configured such that the layer is positioned at an opposite side of the shaft relative to another layer (21b) to form a layer pair (23). The latter layer is oriented at a preset angle with respect to a third layer (21c). Each blade is oriented with respect to a media flow e.g. wind flow, so as to produce rotation in the turbine.    USE - Orthogonal turbine e.g. six-layer turbine and single-blade orthogonal turbine, for use in an orthogonal power unit (claimed) and environmental friendly power generating plant e.g. low-pressure or free-flow river power plant, tidal power station or wind power station, located in river or intertidal area for generating electrical energy from a media flow e.g. wind flow, water flow and intertidal flow.    ADVANTAGE - The turbine increases efficiency of fluid medium power conversion with the blades and eliminates imbalance of the blades without the need for special masses at a side opposite to the blade while reducing material utilization. The turbine can be simplified in design due to absence of balancing weights. The turbine having increased performance and working reliabilities can be achieved with prolonged service life. The power unit having the turbine can be installed in river and intertidal area in an eco-friendly manner. The conditions for maximum efficiency of each turbine blade usage and for simplification of the orthogonal turbine design are obtained due to the absence of any balancing weights, and the orthogonal turbine performance reliability is achieved.
