Cross-Flow Corrected Axisymmetric Solution for Multiple Body Interference.

Abstract : The objective of this effort was to develop the theoretical solution required to define the mutual aerodynamic interference associated with the carriage and release of weapons in the multiple mode. The cross-flow solution for multiple axisymmetric bodies that was previously generated was used to correct the axisymmetric solution in order to account for the mutual interference effects. An equivalent cylindrical body was generated by conformal transformation in order to simulate, as if axisymmetric, the finned portions of the bodies. The analysis reported is for three M-117 bombs in the vicinity of a triple ejector rack; however, any axisymmetric, slender pointed weapon shape could be used. A limited amount of experimental work substantiating this theoretical solution is included as part of this effort. The resulting analytical solution has been programmed for use on both the IBM 360/50 and the CDC 6600 computers. (Author)
