Abstract : The report represents an interim stage of a research program sponsored by ONR to try and put the basic mathematics of design and flow analysis methods for two-element airfoil systems on an equivalent footing to that of single element configurations with the ultimate end in view of producing 'optimum' designs. Techniques of conformal mapping and multiple image reflection are used to solve problems connected with two disjoint circles and then to develop the integral equations describing problems of real interest posed in a canonical domain -- the annular space between two concentric circles. Using this point of view, the essential character of a promising general technique is deduced. (Modified author abstract)
