FIELD: power industry.
SUBSTANCE: in method of moving flow impact on screw of wind or hydraulic motor the kinetic energy of moving flow having constant velocity is converted to alternating pulse flow that is applied to the screw at transient processes, at occurrence of inertia properties of the flow, at mechanical resonance. In the device implementing the above method the smallest section of pipe channel 4 arranges slot-screw group consisting of coaxial slot-type fairing disc 1 with fairings, control slot-type disc 2 and screw 3. When the slots are fully open, screw 3 blades form together with fairings a wing airfoil. Slot-screw group for control of screw 3 rotation frequency changes the size of slots by rotating control slot-type disc 2.
EFFECT: increasing the conversion efficiency of kinetic energy of moving constant flow to mechanical energy of rotating screw.
