Weapon Weight Reduction Using Genetic Algorithms (WREGAL)

A team comprising NextGen Aeronautics and Purdue University proposes a software design that will integrates the processes of structural design, analysis, and optimization tools. The preliminary design, optimization variables, finite element mesh, and other structural properties will be set-up in terms of B-spline parameters and a global search for the optimum design will be conducted using a genetic algorithm. The software will have the capability of automatic mesh adaptation and parallel processing. It will evaluate different design alternatives using external finite element solvers such as ABAQUS and NASTRAN through Application Programming Interfaces (APIs). Apart from ensuring the cross-platform suitability of the software, special emphasis will be placed on minimizing user intervention after initial problem set-up. Under a potential Phase II program, we will implement of the software design, and demonstrate its capability and effectiveness. The planned effort complements the current research work being done at NextGen and Purdue University. To ensure near-term technology transfer, NextGen Aeronautics plan to coordinate the Phase I efforts with major aerospace and automotive companies, and include them on the team on a Phase II program.
