摘要
根据KMM型号螺旋桨随边切割的试验结果,分析切割量对螺旋桨敞水性能的影响,并以图谱形式给出KMM型号螺旋桨转速的相对改变量与切割量之间的关系。应用升力面方法理论计算螺旋桨切割前后的敞水性能,与试验值的比较表明计算值误差在可接受的范围内。
Based on experimental results of a series of open water tests of a KMM propeller under ditierent cut conditions, effects of the trailing edge cut amount on open water characteristics of the propeller were investigated. The relationship charts were provided between relative variations of KMM propeller speed and relative cut amounts. Meanwhile the open water characteristics of the propeller were predicted by using the lifting surface theory. Comparison with to experimental data showed that calculation errors are acceptable.
