Summary

This paper extends some earlier work by Woods [8] on the transient forces caused by unsteady transverse motions of a rigid cascade of aerofoils to the case when the inlet velocity is varying in magnitude. The flow is incompressible and two-dimensional. Expressions for the growth of lift and moment on a member of the cascade with increasing inlet velocity are evaluated and shown to be generalizations of Wagner's classical results for an isolated aerofoil.
