Abstract: The resistance composition and variation law of high-speed displacement vessels are different from displacement ships and planing craft. This paper analyzes the resistance characteristics of the high-speed displacement ship based on model tests and graphic results, and studies the influence of the hull form characteristics, such as displacement volume length coefficient, prismatic coefficient and block coefficient, on the ship resistance. It can provide a certain reference for the design of the power performance of similar ships.

Key words: high-speed displacement ships, resistance performance, resistance estimation

摘要： 排水式高速艇的阻力构成和变化规律与排水式船舶、滑行艇不同。文章基于模型试验和试验图谱分析了排水式高速艇的阻力特征,并研究了排水体积长度系数、棱形系数、方形系数等船型特征对该型船阻力性能的影响,从而为该类船舶的快速性设计提供一定的参考。
