摘要
为了分析波浪状态下的螺旋桨水动力性能,文章采用试验的方法对某型桨在某规则波条件下不同沉深时的水动力性能进行了系统的研究。主要研究了静水中不同沉深对螺旋桨推力系数、转矩系数以及效率的影响。对波浪中不同桨轴沉深下的螺旋桨定常与非定常特性也都进行了研究。对螺旋桨的吸气现象、飞车现象进行了详细讨论,同时对波浪中螺旋桨的非定常特性进行了分析。
In order to study hydrodynamic performance of propeller in waves, experiments of a certain propeller were carried out under the same regular waves and different depths of propeller shaft in open water conditions. The influence of depths of propeller shaft on thrust coefficient, torque coeffi- cient and efficiency in calm water were mainly studied. The steady and unsteady characteristics of the propeller in waves were studied as the different depths of propeller shaft. The air-ingestion and run- away phenomenon of propeller and the unsteady performance of propeller in waves were also analyzed.
