Consequently if the shape of the whole vortex system is known and the velocity
circulation values within it are related in some way to the design and operational
parameters, then the following approach to the determination of the induced ...

However, a more refined approach would require recognition of the fact that at
high angles-of-attack, the blade sections would experience an unsteady-
aerodynamic phenomena governed by the reduced frequency of oscillations of
