摘要
分别应用Morgan关于近似法的理论与Lerbs关于精确法的理论进行螺旋桨环流理论(升力线理论)设计,并将用2种方法分别计算得到的切向和轴向诱导速度、环量分布和升长系数进行对比。由计算结果得知二者相当接近,因而实际应用中在螺旋桨初步设计阶段可以使用近似法较为简便地进行估计。
Morgan＇s theory about Goldstein function method and Lerbs＇ s theory about rigorous method were separately utilized to carry out marine propeller design. Circumferential induced velocity,axial induced velocity,circulation distribution and lift coefficient calculated separately by two methods were comparatively analyzed. The results of two methods are relatively close to each other,so Goldstein function method can be used for simple estimates in the preliminary propeller design stage in practical application.
