摘要
由于极地海洋环境的复杂多变,极地船舶在航行过程中所遭遇的冰条件也呈现出多种特征,冰区航行吊舱推进器在破冰航道工作容易导致破碎冰滑行到吊舱推进器附近的流场,改变了吊舱推进器的流场不均匀性,进而导致螺旋桨上的脉动压力产生变化。同时由于破碎冰的存在,吊舱推进器需要在低转速高推力下工作。本文研究冰区吊舱推进器在冰载荷下的特性。
Due to the complexity and variability of the polar marine environment,the ice conditions encountered by polar ships during navigation also present a variety of characteristics.The work of the pod thruster in the ice-breaking channel in the ice zone is easy to cause the broken ice to slide to the flow field near the pod thruster,which changes the non-uniformity of the flow field of the pod thruster,and then leads to changes in the pulsating pressure on the propeller.At the same time,due to the existence of broken ice,the pod thruster needs to work at low speed and high thrust.This paper studies the characteristics of pod thrusters in ice zone under ice load.
