Expanded MDO for Effectiveness Based Design Technologies

Kenneth M. Mull (Lockheed Martin Aeronautics)

The Expanded Multidisciplinary Design Optimization (MDO) for Effectiveness Based Design (EXPEDITE) program is an Air Force Research Laboratory (AFRL) program that seeks to address challenges in the modern aircraft design conceptual design process by expanding methodologies and techniques to make informed, data driven design decisions earlier in the process.

Lockheed Martin , the prime contractor for this research, building off successes with the ESAVE program, adopted a parallelized approach towards developing and investigating the challenge of effectiveness-based design. These parallel efforts included explorations of optimization modeling and techniques, high performance computing, transient subsystem modeling, uncertainty quantification (UQ), cost and reliability, and state-based modeling and path dependency. One of these parallel efforts focused on collaboration with ESTECO. ESTECO’s design optimization software, modeFRONTIER and its server based collaborative data management and distribution software, VOLTA, comprise the core MDO modeling software utilized in this thrust of the EXPEDITE program. This collaborative and parallel track allowed for an industry wide push to improving multidisciplinary optimization frameworks and the subsequent tools and analysis needed to attempt the EXPEDITE design problem.
