Abstract:

The report presents a complete discussion of a method for calculating potential flow about arbitrary lifting three-dimensional bodies without the approximations inherent in lifting-surface theories. The basic formulation of three-dimensional lifting flow is pursued at some length and some difficulties are pointed out. All aspects of the flow calculation method are discussed, and alternate procedures for various aspects of the calculation are compared and evaluated. Particular emphasis is placed on the handling of the bound vorticity and the application of the Kutta condition, and it is concluded that the approach used in the method of this report has certain advantages over alternate schemes used by other existing methods. A considerable number of calculated results for various configurations are presented to illustrate the power and scope of the method.
