发明名称 WATERCRAFT PROPULSOR (VERSIONS)
摘要 FIELD: propulsors for watercraft of smaller fleet, mainly sailing vessels. ^ SUBSTANCE: proposed propulsor has vertical shaft kinematically connected with propeller. Propulsor is mounted above ascending air flow from naked flame, from burners for example. Each blade is formed by bending rectangular sheet made from heat-resistant material, from titanium alloy for example over radius through angle of 180°. Propulsor is secured together with flame source, burners for example on frame hinged over stern or on watercraft stern. According to first version, blades are secured on shaft over circumference. According to second version, blades are located in parallel and are mounted on struts at angle of 45° relative to ascending air flow from naked flame source. According to third version, watercraft propulsor has one blade mounted on two struts at angle of 45° relative to ascending air flow from naked flame source and its geometric center is located above ascending air flow from naked flame source, from burner for example. ^ EFFECT: possibility of motion of sailing vessels at dead calm. ^ 4 cl, 3 dwg
