摘　　要：船舶在航行中需要在小舵角范围内频繁操舵以保持航向,因此在小舵角工况下吊舱推进器的空泡性能尤为重要。通过试验,对小舵角(±5°)范围内吊舱推进器的空泡性能进行了观察。同时,在0°舵角工况下,对船体以及吊舱上螺旋桨诱导的脉动压力进行了测量,验证了吊舱推进器的设计及应用状况。For course keeping in service,the podded propulsor should be steered frequently within small helm angles.Understanding the cavitation performance of podded propulsor under such off-design condition is very important.Model tests have been carried out in a cavitation tunnel under small helm angle conditions（±5°range）to investigate the cavitation performance of podded propulsor and to measure pressure fluctuation on the hull and pod-housing,induced by the propeller,at zero helm angle.The podded propulsor design and application for large luxury cruise vessel are identified.
