چکیده
The development of innovative adaptive structures on UAVs (and UUVs), such as morphing wings, can potentially reduce system complexity by eliminating control surfaces and their auxiliary equipment. This technology has the potential of allowing a UAV to adapt to different mission requirements or executing a particular mission more effectively. The first part of the paper deals with a review of morphing technologies and some preliminary evaluations for the feasibility of a UAV morphing wing made of composite and “smart” materials, in order to achieve flight control and eliminate the need of the traditional control surfaces. The second part presents the study of a new smart composite material consisting of shape memory alloy NiTi as a precipitate within a compliant Titanium alloy (Gum Metal) matrix.

Morphing aircraft are a focus today due to their ability to combine multiple mission flexibility with a single vehicle. The Hyper-Elliptical Cambered Span (HECS) wing is one such wing being developed as a testbed for morphing technologies, due to its ability to vary the spanwise curvature in order to alter a craft’s lift-to-drag performance. Through analysis of the aft-swept wing geometry and r...
