    Abstract

    The ability of morphing aircraft to adapt their shape in flight hinges on the incredible flexibility of their skins, which have multiple degrees of freedom. This paper presents a compact overview of the latest advancements in polymorphing skins for morphing aircraft, focusing on polymeric skins, electroactive polymers, and shape memory polymers. It examines the critical mechanical properties such as flexibility, durability, and resilience that influence their application in morphing wings. By detailing the synthesis processes, including the use of natural rubber, silicone, acrylic, and fiber-reinforced composites, and exploring various modeling and simulation approaches, the paper highlights the importance of flexible material selection and design principles tailored to morphing aircraft needs. It emphasizes a multidisciplinary strategy integrating polymer material science, mechanical engineering, and aerodynamics to innovate in the morphing aircraft domain. This review aims to serve as an essential resource for researchers and practitioners, paving the way for future developments in aerospace morphing technologies.
