本文介绍了平板螺旋诱导器的实验结果。为了给螺旋诱导体的设计提供充分的数据，制作并试验了各种螺旋诱导体。系统地改变了叶片数量、叶片长度和叶片角度，并测量了各诱导体的整体性能和出口流动状况。所得结果可总结如下。(1)叶片数和叶片长度均有最优值。(2)出口轴向速度与进口轴向速度之比约为1.3，尽管诱导体和流量不同，但转角和压力损失仅与攻角有关。因此，利用这些结果可以很容易地估计头部上升。
This paper presents the results of experiments on flat-plate helical inducers. In order to offer sufficient data for designing helical inducers, various inducers were fabricated and tested. The number of blades, the blade length and the blade angle were varied systematically, and the overall performance and exit flow condition of each inducer were measured. The results obtained can be summarized as follows. (1) The number of blades and blade length have optimum values. (2) The ratio of axial velocity at outlet to that at inlet is about 1.3, and turning angle and pressure loss depend only on attack angle, in spite of the differences in inducers and flow rate. Consequently, head rise can be easily estimated using these results.
