Local and Global Search Methods for Design in Aeronautics

J. Peter, G. Carrier, D. Bailly, P. Klotz, M. Marcelet & F. Renac
Optimization is used at all stages of aircraft design. In the early phases (also called preliminary or conceptual design) multicriteria Pareto optimization based on heuristic laws is carried out. Conversely, in the late design phases, accurate structural and aerodynamics predictions are required to steer small changes of a baseline shape through mono-objective optimization. This article is devoted to the local and global optimization methods actually used during this second part of the design process. Through...
