Multimission Aircraft Fuel-Burn Minimization via Multipoint Aerostructural Optimization
TL;DR: In this article, a new strategy to formulate multipoint design optimization problems is developed that can maximize the aircraft performance over a large number of different missions, which is applied to the high-fidelity aerostructural optimization of a long-range twin-aisle aircraft.
