Optimized design of real-scale A320 morphing high-lift flap with shape memory alloys and innovative skin

Abstract

This article proposes a design approach based on multi-criteria optimization. Applied to the conceptual design of a cambered control flap of Airbus A320, different skin technologies and actuator topologies are compared. Amongst the possible shape memory alloy actuators, an agonist-antagonist solution is found the most suitable for the application. Elastic skins are compared to a bio-inspired innovative skin and feather concept. The results are based on simplified but realistic aircraft specifications that consider environment and industrial concerns. Finally, the optimization results in a feasible low weight, low power consumption morphing wing design. This design is a basis for detailed incoming integrated aircraft system.
