Abstract : A study is described of the application of an electric analogy to problems of aerodynamic interference between aircraft and missiles. Earlier investigations indicated that available techniques were almost entirely inadequate for handling interference problems in the transonic speed range. An effort was made to provide at least one simple method for handling these problems. The basic approach followed has been the use of slender body aerodynamic theory and two-dimensional electric analogy methods. While slender body theory has many inherent limitations, its use reduces a complex three-dimensional problem to a much simpler two-dimensional problem in potential theory. Thus, all the powerful classical tools for solution of Laplace's equation with specified boundary conditions can be employed. In particular, when the boundary conditions are too complex for easy analytic solution, the electric analogy provides a convenient means for direct and relatively simple evaluation of induced loads on a missile in the non-uniform aircraft flow field.
