Abstract:

The complexity and cost of modern combat aircraft and their weapon systems, combined with the requirement for increasingly accurate release trajectory data, has resulted in the need for a complete reappraisal of the traditional jettison trajectory prediction techniques both analytical and experimental, and the development of new and potentially more reliable and accurate techniques. It is well known that the most commonly used techniques of simulating store jettison trajectories in a wind tunnel at high speeds do not fully satisfy dynamic scaling requirements. The method employed at BAe Brough is light model scaling, with parent model acceleration to compensate for the gravitational deficiency inherent in this technique. A detailed analysis of residual errors in simulation has led to a method of minimizing the most significant of these i.e. induced incidence deficiency, which has now been incorporated into the technique.
