Advances in Modeling and Simulation Capabilities for Predicting Store Trajectories - Past Success and Future Challenges
Abstract
Any time a new aircraft is introduced into service, or an old aircraft undergoes substantial modifications or needs to be certified to carry and employ new stores, the store separation engineer is faced with a decision about how much effort will be required to provide an airworthiness certification for the aircraft and stores. Generally, there are three approaches that have been used: Wind Tunnel Testing, Computational Fluid Dynamics (CFD) analyses and Flight Testing. During the past twenty years there have been considerable advances in all three areas. In particular, the US Navy has developed an integrated approach that uses the best features of the three approaches to improve the process. This approach has led to a continuing improvement in the Navy's Modeling & Simulation (M&S) capability for store separation. In this paper M&S refers to the combination of store freestream and grid data (obtained either from a wind tunnel or via CFD) in a six degree of freedom program to compute store trajectories. This paper presents the latest result in this process.
