Store Unsteady Aerodynamic Loads Measurement Technology

M4 Engineering proposes to develop a method for accurately measuring unsteady aerodynamic loads on stores. This effort will include a characterization of the significant challenges currently impeding dynamic load measurement. This work will include development of a hardware prototype CTS system that incorporates vibration reduction, novel sensor use, advanced analytical measurement system, or a combination of these technologies. The proposed development will create an excellent compliment to modern test and analysis methods. BENEFIT: The proposed development has the potential to dramatically improve the analysis and certification process for stores. Demand for this capability will be found in the government and at major airframe manufacturers. Phase II development will result in a commercial CTS components that satisfy this demand. Combination of unsteady loads data collected with these developments with advanced trajectory simulation capabilities will allow engineers to accurately and rapidly predict store separation trajectories in order to avoid unpleasant “surprises” during development, testing, and service. Initial implementation will focus on store load measurement, however the capability created will apply to other systems subjected to unsteady loading environments. Satisfying this existing demand will provide a tremendous commercial potential for this technology.
