Computational Design in Aerostructures: Topology Optimization for Conceptual Design and Trade Studies

CDFAM Computational Design Symposium — Washington DC 2026

Brandon DeMille · General Atomics Aeronautical Systems

Computational design methodologies, including topology optimization, are transforming airframe structures development by enabling rapid exploration of design configurations during early conceptual phases. This presentation demonstrates a workflow that enables informed decision-making across disciplines and accelerates the path from initial concept to detailed design. A fuselage case study illustrates the simultaneous optimization of composite laminates for skins, substructure geometry, and overall shaping. This integrated approach facilitates quantitative trade-offs among competing priorities such as cost, structural performance, manufacturability, and production rate.
