Abstract

The mutual aerodynamic interference problem for external aircraft-stores has been analyzed using the image system technique. To facilitate this analysis it has been assumed that small perturbation solutions are valid. It is further assumed that the external stores are slender, axisymmetric bodies and that the mutual interference can be analyzed by first assuming a cross-flow solution. Both body-body and wing-body interference solutions have been obtained. The first were considered in Part I of this paper. For the wing-body solution, the image systems in the cross-flow plane consist of vortex pairs appropriately located by using the Milne-Thomson circle theorem. The strengths of the image vortex system are then determined by satisfying the body boundary conditions at designated control points on the external stores. Good agreement has been found between the theoretical and experimental results.
