Prevention of Corrosion for Navy Aviation

This proposal describes the development of aircraft simulation and modeling analysis system for predicting the degradation of aircraft structures due to corrosion. This will be achieved by extending the existing ACES software product developed by GCAS under Army contract to NAVAIR aircraft structures, materials and corrosion failure modes. This includes identifying and modeling the detailed failure mechanisms for different forms of corrosion and material degradation relevant to aircraft including Pitting, Stress Corrosion Cracking and Exfoliation which are the primary sources of corrosion related failures on aircraft. The existing ACES product already includes methods for simulating uniform, galvanic and crevice corrosion. The software will include parallel computing versions of the proposed geometry search and feature recognition algorithms for use on HPC or GPU architectures and a Knowledge Acquisition Facility that will allow end user organizations to update the Knowledge Base with new information as it becomes available in the future.
