为了降低双体无人船在波浪中航行时的阻力，以片体长宽比、片体间距以及重心纵向位置为设计变量，根据均匀设计原理拟定不同的设计方案，运用数值计算方法对迎浪航行状态下双体无人船的静水阻力和波浪增阻进行分析，得出阻力与设计参数之间的关系，基于总阻力最小并计入总布置对船型设计的限制对双体无人船船型方案进行优选，得到波浪中阻力性能较优的方案。
In order to reduce the resistance of catamaran unmanned surface vehicle in waves, various design which take length-width ratio, demihull spacing and longitudinal center of gravity as design variables are developed by the principle of the uniform design, and the relationship between resistance and design parameter is obtained after the calm water resistance and added resistance-in-wave at head seas of each cases is analyzed by means of numerical method. Finally, a new design with better resistance performance in waves taken overall consideration of the limitation of general arrangement on ship design and based on the minimum total resistance.
