大型集装箱船上大侧斜螺旋桨模型脉动压力的比较试验研究

Comparative Experimental Study on Fluctuating Pressure Induced by Highly-skewed Propeller Models for a Container

对一艘大型集装箱船，按图谱方法设计了一个常规桨，在相同的设计条件下按升力面方法设计了两个不同侧斜角的大侧斜桨。三个桨模在中国船舶科学研究中心大型空泡水筒中用假船尾加网格模拟的伴流场中进行了脉动压力测量。测量结果表明：大侧斜桨与常规桨比较可以明显地降低螺旋桨对船体诱导的脉动压力，下降幅度达３０％左右。

Two highly-skewed propellers for a container have been designed by means of design package developed by CSSRC. At same design condition a conventional MAU propeller was designed as well. The fluctuateing pressure measurments were carried out in wake field simulated by dummy model in large cavitation tunnel.Results show the fluctuating pressures induced by highly-skewed propeller are 30%. low than coventional one.
