“…Morphing wings and adaptable structures are the most often chosen approaches to improve the existing aircraft with fixed wings, whose adaptive configurations are typically formed by mechanical rotations, in response to the growing need for the high mobility and fuel economy of modern aircraft. The common use of AM in conceptual research on morphing wings makes use of the great efficiency and low cost of 3D printing [ 167 , 168 , 169 , 170 , 171 , 172 , 173 , 174 , 175 ].…”

The scientific community is and has constantly been working to innovate and improve the available technologies in our use. In that effort, three-dimensional (3D) printing was developed that can construct 3D objects from a digital file. Three-dimensional printing, also known as additive manufacturing (AM), has seen tremendous growth over the last three decades, and in the last five years, its application has widened significantly. Three-dimensional printing technology has the potential to fill the gaps left by the limitations of the current manufacturing technologies, and it has further become exciting with the addition of a time dimension giving rise to the concept of four-dimensional (4D) printing, which essentially means that the structures created by 4D printing undergo a transformation over time under the influence of internal or external stimuli. The created objects are able to adapt to changing environmental variables such as moisture, temperature, light, pH value, etc. Since their introduction, 3D and 4D printing technologies have extensively been used in the healthcare, aerospace, construction, and fashion industries. Although 3D printing has a highly promising future, there are still a number of challenges that must be solved before the technology can advance. In this paper, we reviewed the recent advances in 3D and 4D printing technologies, the available and potential materials for use, and their current and potential future applications. The current and potential role of 3D printing in the imperative fight against COVID-19 is also discussed. Moreover, the major challenges and developments in overcoming those challenges are addressed. This document provides a cutting-edge review of the materials, applications, and challenges in 3D and 4D printing technologies.

“…To assure the required smoothness of the external surface, the fingers are filled each others by a specific deformable skin. 52 Also in this case, the deformation stored in the skin causes a reaction on the supporting structure, the wen of the rear spar. Finally, the winglet is equipped with two independent flaps.…”

The scope of this work is to provide a critical review on the expectations about the morphing wing technology against the current open issues and showstoppers. In synergy to other emerging and promising technologies, morphing is asked for bridging the evident gap between the current growth trend of the aerospace compartment and its impact onto the environment. The potential of morphing, in particular, its primary impact on the aerodynamic efficiency of the aircraft, primed the investigation of different technologies, achieving interesting results but often highlighting limitations and showstoppers against the airworthiness regulations. The authors focus their attention on some specific aspects that characterize the morphing wing attachments and that may represent weakness points for the maturation of the technology: the load transmission of the movable parts to the supporting wing box, the way the flexibility–rigidity paradox is addressed by specific critical components (the skin), the scalability dependence of the morphing architectures, and the specific aeroelastic behavior of the nonconventional architectures.

“…The deformation function of the morphing wing flexible skin can be realized in three main ways [12]: the deformation of the elastic material itself [13], the sliding or rotating deformation of the mechanism, and the large deformation of the sandwich composite structure. A hybrid material flexible skin of a Kevlar/carbon-fiber-reinforced silica gel matrix for a shear swept morphing wing was proposed by Yu et al [14].…”

A multi-dimensional morphing wing skeleton mechanism is proposed with double-sided triangular pyramid units, which can realize continuous variable span-wise bend, span-wise twist, and sweep. A lockable morphing unit is designed, and its mechanism/structure characteristics, degree of freedom, and the deformable function of its deformable wing skeleton mechanism are analyzed. One kind of flexible skin is proposed to meet the performance requirements, consisting of an internal metastructure and a flexible surface bonded on both sides. The morphing wing skeleton mechanism and the equivalent treated metastructure flexible skin are then combined. Subsequently, a two-way fluid–structure interaction analysis is conducted to investigate the influence of aerodynamic loads on the flexible skin and skeleton mechanism in different deformation states, including the influence of structural passive deformation on the aerodynamic characteristics of the morphing wing. The computational fluid dynamics method is employed to analyze the aerodynamic characteristics of the morphing wing in its initial state, as well as in three deformation states, and to study its aerodynamic performance in different flight environments.
