In this report, a method is presented for the calculation of a potential flow through straight cascades of thin wings. The calculation of the flow has been based on the singularity method : normal velocities v are cubic functions of abscissae x, and tangential velocities u, corresponding to normal velocities v (=0,1,x, x^2,x^3), are determinable by a conformal mapping of the cascade into a unit circle. As the author has introduced the recurrence formulae for velocity functions, an improved accuracy has been obtained by using the velocities u of higher degree. This method will be applied to the calculation of the flow through a centrifugal pump impeller in the following reports. In this report, the author has applied it to the calculation of the flow through a straight cascade of thin wings, comparing with the results hitherto published in numerical examples.
