Abstract
The acceleration potential has been used to reformulate the integral equation relating pressure and downwash on the blades of cascades. In the present investigation harmonically oscillating blades in subsonic flow have been considered. A collocation method as used in lifting surface theories for single airfoils has been adapted to solve the cascade equation. Pressure distribution and airforces have been calculated for several values of stagger, reduced frequency, space-to-chord ratio, Mach number, and inter-blade phase angle. The results have been compared to those published in other reports and, in some cases, significant differences have been discovered.
