Abstract:

A recently developed general theory of aerodynamics is used in an investigation of non-linear unsteady flow problems involving a non-rigid lifting body. It is shown that this theory, developed on the basis of viscous flow equations, permits the important interactive fluid dynamic elements dominating the aerodynamics of non-linear unsteady flows to be identified and their contributions evaluated individually. Closed form expressions for the lift, the drag, and the power expenditure of the Weis-Fogh problem, considered as a special case of flexible lifting bodies, are presented and discussed.
