The article provides information on the development and design of an Archimedean screw turbine for low-pressure microhydroelectric power plants. When developing the Archimedes screw turbine, parameters such as its length L, outer shaft diameter D0 and working diameter Di, blade period S, number of blades n were taken into account. When the deflection angle of the Archimedean screw turbine was changed from 200 to 450, the shaft rotation speed was achieved from 160 to 280 times, and the excitation torque decreased from 0.15 to 0.06. The maximum power was 5445 W at a turbine shaft speed of up to 280 times. It was observed that the drive torque increases with decreasing turbine shaft rotation speed. Based on the above parameters, a model of an Archimedean screw turbine was developed.
