Abstract

In linearized optimization theory, lifting surfaces shed tip vorticity of which the strength has in general infinite square root singularities. Here we impose, besides the usual condition on the force action of the lifting surfaces, also a condition on the strength of their shed vorticity by which it remains bounded. Then the existence of a unique optimum under both conditions is proved. Copyright © 2002 John Wiley & Sons, Ltd.
