The technology paradigm presented in this paper is to provide active control of winglet structure subject to external stimuli to meet operational performance criteria, by means of smart actuation integration. A tier schedule is employed to develop application to take full advantage of material compliance through MDO to form functionally active integrated non-planar wing, to improve multi-phase mission performance, manoeuvrability and integrated economics (e.g., 5-6% augmented aerodynamic eciency throughout the flight envelope, compared to 3% of current fixed winglets). This paper presents the first steps of the hierarchical methodology (i.e., smart actuation ecient down-selection) towards the final morphing application (i.e., MORPHLET), through the technology selection and preliminary optimized non-planar wing schedules.
