Morphing wings have a large potential to improve the overall aircraft performances, in a way like natural flyers do. By adapting or optimising dynamically the shape to various flight conditions, there are yet many unexplored opportunities beyond current proof-of-concept demonstrations. This review discusses the most prominent examples of morphing concepts with applications to two and threedimensional wing models. Methods and tools commonly deployed for the design and analysis of these concepts are discussed, ranging from structural to aerodynamic analyses, and from control to optimisation aspects. Throughout the review process, it became apparent that the adoption of morphing concepts for routine use on aerial vehicles is still scarce, and some reasons holding back their integration for industrial use are given. Finally, promising concepts for future use are identified.

a b s t r a c tThe aim of this paper is to verify the control of the stiffness that is feasible to achieve in a thin walled box beam made from a laminate by including an adaptive material with variable stiffness. In this work, a material having a strongly varying Young Modulus under minor temperature changes was included in the cross section. An analytical model was used to estimate the position of shear centre and the axial, bending, torsional, and shear stiffnesses of the cross section. Two cross sections were analysed, one with an adaptive wall and another with two adaptive walls. In both sections, the torsional stiffness could be strongly altered with minor temperature variations. In the section with one adaptive wall, the shear centre and thus the bending twist coupling was also strongly modified. A study was made of the influ ence on the control of stiffnesses exerted by the overall cross section thickness and the thickness of the adaptive walls.

“…It has many applications of advanced engineering machinery such as mechanical arms, deployable mechanisms, and morphing wings. A morphing wing [1][2][3][4] can change its camber using variable camber mechanism as shown in Figure 1. The mechanism creates a camber that improves the aerodynamic characteristics of an aircraft, increasing the lift coefficient from 0.08 to 0.4 for a civil airplane wing.…”

This article proposes multiple hinges' type spectrum that provides an effective description of the multiple hinges of planar kinematic chains. The relationships between characteristic invariants are established and applied into type synthesis methods. A type synthesis method for planar kinematic chains, which is called the characteristic spectrum analysis type synthesis method, is proposed. A systematic design method for variable camber mechanisms is proposed. Using the results of the type synthesis and the systematic design method, three design schemes are proposed and the mathematic models are set up. Some simulation analysis has been done. All these analyses can verify the deformation performance of the proposed mechanism.
