This report is the final technical report which describes a combined theoretical-experimental program which has been conducted with the aim of developing a computer program to predict three-degree-of-freedom trajectoreis of stores when dropped from fighter-bomber type aircraft at speeds up to the critical speed. Both single store and multiple store installations are treated. The report first describes the mathematical models used to represent the various aircraft components. Then the calculation of the flow field, accounting for primary interference effects, using these models is described followed by the method of calculating the normal force and pitching moment from this flow field. A method of accounting for additional interference between the wing, pylon, and store is next presented.

The primary objective of this report is to present a prediction method for determining the forces, moments, and six-degree-of-freedom trajectories associated with stores released from single, TER, or MER configurations on fighter-bomber aircraft up to the critical speed. A secondary objective is to present important experimental results and comparison with theory from an extensive wind-tunnel test program designed to provide data to test the theory through systematic measurements of flow fields, store load distributions, store forces and moments, and captive-store trajectories.
