摘　　要：运用升力线、升力面以及面元法理论为海事40 m级巡逻船设计新型螺旋桨。采用给定环量分布进行螺旋桨理论设计,并通过桨模敞水试验和实桨装船后的实船测试验证该桨的理论设计方法。实船测试主要通过2条相同船型的实船,分别加装图谱桨和理论桨进行航速、轴功率、艉部振动对比测试,用实船试航的试验数据对比分析理论桨相对图谱桨的性能指标。结果表明:采用理论方法设计的螺旋桨相对原来的图谱方法,与船型匹配得更加精确,实船的螺旋桨效率约提高2%;船体艉部振动约减小5 dB。A new propeller is designed in this paper for MAS＇s 40 m patrol ships. Particularly, the lift- ing-line and lifting-surface design method as well as the panel method are employed, and the given circu- lation distribution is adopted during the propeller theoretical design. For validation, both open water model tests and real ship tests were conducted. The ship tests were performed on two ships of the same type, yet one ship was equipped with an atlas designed propeller, while the other was equipped with the theoretical designed propeller. The parameters of speed, shaft power and aft vibration were compared and analyzed be- tween the two models. It is observed that compared with the atlas designed propeller, the one designed by the theoretical method has a closer match with the ship, which is more efficient in propelling （with an in- crease of approximately 2% in the real ship propeller efficiency） and superior in noise reduction （with a de- crease of about 5 dB in hull aft vibration）. Therefore, the feasibility and reliability of the proposed design method in practical applications are successfully proved.
