Embraer's Aeroelastic Tailoring Framework pioneers a nonlinear structural stability approach to reduce aircraft emissions. Tests on a simplified version of NASA's CRM wingbox achieved up to 29.6% mass reduction, surpassing linear methods. Using MSC Nastran and OpenAeroStruct, the study explores complex scenarios, promising more efficient and lightweight airframes for sustainable aviation.
