DIRECT-FLOW PROPULSOR

摘要

FIELD: transport.SUBSTANCE: invention relates to converters of engine or other energy source work into that driving transport facilities. Proposed propulsor is composed of hollow cylindrical multistart screw jacket made up of one and more equal-width bands. Screw lines and surfaces are made on jacket outer surface directed in one direction at 5°-45° to its lengthwise axis. Surfaces feature polygonal shape composed of different geometrical figures with four and more lateral sides. Said figures differ in both geometry and sizes. Said hollow screw jacket is mounted all along transport facility body to rotate about its lengthwise axis and said body.EFFECT: expanded operating performances.7 dwg
