PROPULSOR, DISC CRAFT, DISC CRAFT LARGE CARRYING CAPACITY, UNDERWATER LIFT-PUSHER, PROPULSOR UNDERWATER VEHICLES Russian patent published in 2016 - IPC B64C29/00 B63H1/12 B64C39/06 

FIELD: engines.

SUBSTANCE: invention relates to design of propellers operated in air and aqueous media. Propulsor is composed of solid hard disc from metal or metal-coated plastic. Upper part of disc is made flat, and bottom is oval or conical. On upper surface of milling in section from 0.5 to 0.3 radius is circular boring at depth of 0.05 disc radius. Circle in 0.5 radius is divided into six equal and from marked points of same radius arc is marked on outer part of wheel disc. Through centre and obtained six points symmetry axes are marked, dividing disc to six sectors. Six arcs are marked on outer part of circle to points of intersection with first arcs, from intersection points of primary and secondary arches in outer edge of disc to disc center six parts of circle are marked to contact with primary arcs. Metal from curvilinear segments of circular bore to sections of arcs are removed to depth of circular bore. Propulsors can be used instead of rotors on disc planes and as propulsors on submarines.

EFFECT: higher lift propulsors.
