In the article it is stated that hydraulic turbines of low pressure mini power plants are not subject to great loads from water flow. Because of that in such hydropower plants it is possible to use the turbines that are cheaper and simpler from a design point of view. The authors offer the description of a developed simplified orthogonal hydraulic turbine using the energy of the water flow. It is suggested to make the blades hollow. It is also suggested to use curved sheet surfaces for the forcing and backside surfaces of blades. Such a design would reduce the consumption of materials and manufacturing costs for a hydraulic turbine.The research is aimed at studying the water flow conditions in the blade area of the proposed hydraulic turbine design. Research methods include mathematical simulation using the software package ANSYS.The results of investigation of water low bypass for such a hydroturbine design obtained with a mathematical model are given.It is proved that the existing design features, and in particular the slits have no detrimental effect on the parameters of the water flow in the immediate vicinity of an orthogonal hydraulic turbine blade. Basing on the research it has been concluded that the use of a designed simplified orthogonal hydraulic turbine is expedient for low pressure mini and micro hydropower plants.
