ROTARY-SCREW SHIP PROPELLER

摘要

FIELD: transport.SUBSTANCE: invention relates to ship propellers. Rotary-screw ship propeller consists of even number of floats which have enveloping spirals along outer surface. On each of propeller levels of ship starting from water line and lower there are two hollow floats. The floats serves as stators for spirals-rotors matched to them. The spirals have stand-alone drive for rotors of corresponding level.EFFECT: better serviceability and increase in ship specific speed.2 cl, 1 dwg
