Store Trajectory Response to Unsteady Aerodynamic Loads

The development of a trajectory envelope prediction tool, capable of identifying stores that may experience significant trajectory deviations due to unsteady loading is proposed. The Phase I part of this program will provide a comprehensive demonstration of the significance of these unsteady loads in determining trajectory envelopes and conceptualize a modeling approach to predict this effect. The modeling tool will be subsequently developed and matures in Phase II through the synergistic use of experimental and computational tools. The methods and procedures used in this program will be collected into a set of testing and analyses procedures for the store certification and clearance process. The incorporation of these into the certification process will improve the accuracy and reliability of this process while expanding its capability with modification to the process. The successful completion of this program will affect current platforms such as the F/A-22, the Joint Strike Fighter (JSF) as well as future platforms such as the Long Range Strike Aircraft (LRSA).
