上海水产大学渔业工程系为推进我国沿海群众渔业技术改造,从1988年起开展了将导管螺旋桨应用于木质渔船的开发研究和技术服务工作。他们在广泛调查研究的基础上,针对群众渔业木质渔船船型、机型及齿轮箱等复杂的特点,确定采用19A导管+Ka系列螺旋桨设计计算,使船、机、桨合理匹配,并根据目前群众渔业的技术状况, Department of Fisheries Engineering, Shanghai Fisheries University In order to promote the technological transformation of coastal fisheries in China, the pilot propeller was applied to the research, development and technical service of wooden fishing vessels since 1988. On the basis of extensive investigations and studies, based on extensive investigations and studies, the design of the 19A Catheter + Ka Series Propeller Propeller was determined in view of the complex features of the mass fishing wooden fishing vessels, models and gearboxes, so as to reasonably match the ships, machines and propellers, The technical status of fisheries,
