Historically gust loads have been excluded from early stages in the aircraft design process in part due to their computational complexity. As air vehicles push the envelops of aspect ratio, there is an increasing need to understand the implications of gust loads as well as incorporating them in the early design process. Work was performed using ASTROS and OpenMDAO to include aeroelastic gust analysis for gust-based stress constraints as well as formalization of the sensitivity equations for the aeroelastic gust responses. The initial implementation of the stress-based gust optimization shows favorable behavior for simple design problems and builds confidence in the ability to increase complexity in later development efforts. Results for both analytical stress sensitivity and finite difference approximation optimization problems are discussed as well as the behavior of the constraint space for larger scale design problems.
