This AGARDograph is a systematic collection of experimental results for use of engineers and designers, limited to externally carried, unpowered, unguided stores. In the sections dealing with store trajectories, the physical situation is described, the method of solution is indicated, and the final results are presented. Emphasis is on store motion in traversing the parent aircraft flowfield, with criteria for safe separation and methods of calculating flight path. Windtunnel test techniques are described, and some information on flight testing given. Analytical treatment is compared with flight and tunnel results. There are brief mentions of ejection systems and the effect of stores on aircraft performance.
