“…When these mechanisms are applied to morphing wings, the driver will be fixed on the wing box, rather than on the variable camber mechanism. It will have lighter weight than the mechanisms in Monner et al, 5 Hardy, 6 Munday and Jacob, 8 Monner, 9 and Elzey et al 10 To compare with the mechanism in Hardy, 6 the structure of the morphing wing is complex. There are so many parts in their mechanism which can be found in the figures in Hardy.…”

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.

“…Once again harmonic actuation at 2/rev could reduce the noise and the vibratory loads on the rotor, improving the rotor performance [18,20]. Most studies on this concept consider the plane as the main application, envisioning morphing flaps as a main control surface [39].…”

“…On the fourth version of the F-14, the F-14D built in 1991, the glove vanes were removed due to their weight and complexity [1]. Since that time many more sophisticated inflight geometry manipulation systems have been tried and the whole field of "morphing" aircraft" has grown enormously, see for example [2], [3], [4], [5], [6], [7], [8], and [9]. Clearly, morphing geometry must not only improve the aerodynamic capabilities of an aircraft, but also cannot have too severe an impact on cost, weight or energy consumption.…”

The development of new technologies -such as rapid prototyping -and the use of materials with improved properties -such as highly resistant extruded polystyrene foam which can be easily and precisely shaped, while conserving its mechanical properties -allow researchers to improve design concepts. This paper details the development of a new set of morphing wings for a 15kg maximum take-off weight Unmanned Aerial Vehicle (UAV) from concept design, to flight tests, including modelling, design optimisation, construction and wind tunnel tests. A set of comparator equivalent conventional wings have been used throughout in order to be able to judge any benefits stemming from the adoption of morphing technology. The paper shows that the morphing wings provide a controllable aircraft while reducing drag by a factor of 40% compared to the comparator wings with conventional ailerons in a deflected position. IntroductionMorphing wings have been studied since the earliest days of heavier than air aviation, no doubt based on the commonplace observation that all birds continuously change the shapes of their wings during flight. The original Wright Flyer used "wing warping" for roll control -a fundamental form of wing morphing. There are many and varied ways that the wings of an aircraft can be altered in shape: the planform can be altered in size or span or sweep, section shapes can be altered, either to change lift magnitude and distribution or to gain vehicle control in pitch, roll, yaw, etc., wings can be twisted to alter effective angles of attack. Aeroelastic effects can be deliberately used to make geometry changes -so called aeroelastic tailoring. If allowance is made for the activation and deployment of conventional control surfaces, almost all aircraft lifting surfaces change shape in some way or other. One of the key recent drivers in morphing wing technologies has been the adoption of composite materials such as carbon fibre reinforced plastics. These have allowed for considerable tailoring of stiffness properties throughout the geometry of the wings so as to allow close control of the shape changes being achieved. In the wings developed here a careful matching of fibre and foam structural elements is used to govern the shapes taken up by the wing as it morphs.
