FIELD: vessels; floating facilities; aviation.
SUBSTANCE: invention relates to ship building and aircraft engineering, namely to water and aircraft propellers, and can also be used as a generator of water and air flows into electric energy. Flow screw is a shaft with blades fixed on it, each of which is ¼ part of torus. Each blade surface inflection point is twisted around the shaft along the same radius in one plane. Each blade surface inflection point moves away or approaches relative to the propeller base plane along the same radius.
EFFECT: higher power of screw.
