| Abstract: | For a certain type of double-deck trawler, a comprehensive model for optimal matching of paddles based on bottom trawler operating conditions and self-propelled conditions was established. The multiple paddles of the paddles were optimized, and ducts and large-diameter propellers were adopted. Through production practices, the high efficiency of the optimized design is verified, the efficiency of the propulsion system of the trawler is improved and the column drag force is increased. |
