A theoretical method proposed by Isay for evaluating the performance of vertical axis propellers was programmed by the David Taylor Model Basin for use on high-speed computers. The results of numerical computations of thrust and torque coefficient and efficiency are presented for a six-bladed vertical axis propeller for a wide range of advance coefficients and maximum blade angles. From the results, it is concluded that, due to certain erroneous assumptions, the theoretical method as presented by Isay cannot be utilized to predict the performance of vertical axis propellers even in a qualitative way.
