Use of the Euler equations to model complex transonic configurations and to predict store loads is well established. Results from further work in this area are presented. Of particular interest is the degree of complexity that can be readily accommodated by the methodology while producing accurate store trajectories. Also of interest is the effect of geometric simplification on the trajectory of a store. Trajectories were computed based on Euler solutions for three aircraft configurations at a free-stream Mach number of 0.98 and aircraft angle of attack of 1.1 deg. All three configurations were comprised of the F-15E body, wing, ingesting inlet, pylons, and targeting pod as the basic geometric arrangement. The configurations differed with respect to the type and arrangement of the stores. For verification the trajectories were compared to both measured online trajectories and computed trajectories based on measured flow fields and measured store carriage loads. The results show that some aircraft geometric details may play a more important role than anticipated in computationally determining store trajectories. The results also demonstrate the capability of using computed store loads and computed flow-field information, independent of or in conjunction with wind tunnel data, to produce trajectories from extremely complex aircraft configurations.
