摘　　要：针对某大型测量船的实际作业需求,提出GONDOLA式的声学设备安装方式,采用CFD数值仿真分析方法对GONDOLA附体型式进行优化设计,计算分析和桨模试验表明,GONDOLA附体优化后不仅能使得船舶具有良好的防气泡性能,降低船舶阻力,还可大幅改善尾部螺旋桨区域伴流场,提高螺旋桨空化临界速度。According to the actual operation requirements of a large survey ship,the acoustic equipment installation mode of GONDOLA was proposed,and the GONDOLA attachment was optimized by using CFD numerical simulation method.The calculation and propeller model tests showed that the optimization of GONDOLA attachment can not only make the ship have good bubble performance and reduce the ship resistance,but also greatly improve the wake field in the propeller area at the stern and improve propeller cavitation critical velocity.
