摘 要:对水下推动器的计算选型,目前国内尚无成熟的计算公式,研究水下推动器选型的计算方法是一个亟待解决的问题。对水下推动器的选型计算进行了探讨,通过分析和推理认为飞力公司关于水下推动器的计算公式在理论上是可行的,通过对摩擦系数的分析和加修正系数而得到了与飞力公式一致的水下推动器选型计算公式。根据推力计算出推动器的输出功率后,可通过厂家提供的产品螺旋桨效率η螺和电机效率η电机来求得推动器所需要的轴功率和装机功率。At present, there is no mature calculation formula for choosing types of submersible propellers in China. To study a calculation method for selecting types of submersible propellers is a problem to be solved exigently. The calculation for choosing types of submersible propellers is discussed. The formula which has been thought out by Flygt is considered to be theoretically reasonable by analysing and inferring. A formula which is conformable with Flygt' s formula has been gotten by analysing friction coef- ficient and adding a correction coefficient. After calculating the output power of submersible propeller based on thrust, the axial power and the installed power necessary for submersible propeller can be calculated by efficiency of propeller and efficiency of motor which are supplied by the manufactory.
