摘　　要：本文通过试验方法研究多种附体对不同载况下高速排水型船阻力及航态的影响。开展了正常排水量和满载排水量两种载况模型试验,讨论了长防溅条、长防溅条分别和压浪板、阻流板的组合附体对船体阻力和航态的影响,分析了不同附体的适用航速和载况。长防溅条与压浪板或阻流板的组合不仅能够很好地弥补长防溅条单独使用所带来的纵倾角增大问题,而且在两种载况下均具有良好的减阻效果,减阻率最大可以达到20%以上。The effects of various appendages on the resistance and navigation motion of high-speed displacement crafts under different loading conditions were studied by experimental methods.Model tests of normal and full displacement were carried out.The influence of long spray strips,the combination appendages of long spray strips with the wave plate or the interceptor on the resistance and navigation motion of the crafts was discussed,and the applicable speed and loading state of different appendages were analyzed.The combination of long spray strips with the wave plate or the interceptor could not only make up for the increase of longitudinal angle caused by the use of long spray strips alone,but also have a good drag reduction effect under both load conditions,and the maximum drag reduction rate could reach more than 20%.
