“…Furthermore, the effects of passive controllers have also been investigated by several researchers to increase the linear flutter speed (Agneni, Mastroddi, & Polli, 2003;Agneni, Sorbo, Mastroddi, & Polli, 2006;McGowan, Heeg, & Lake, 1996). Researchers have also used piezoelectric materials as actuators for morphing wings or morphing aircraft (Bilgen, Kochersberger, Diggs, Kurdila, & Inman, 2007;Schultz & Hyer, 2004). Moreover, Macro-Fiber-Composite (MFC) actuators have been used to suppress buffeting oscillations on the vertical fins of an F-18 (Sheta, Moses, Huttsell, & Harrand, 2003;Wickramasinghe, Chen, & Zimcik, 2007).…”

“…Consequently, assumptions are often made to produce simple and accurate predictions of the VIV phenomenon and the structural response. The widely employed approach or representation is the so-called wake oscillator model, which was first put forward by Birkhoff and Zarantanello (1957). The ensuing researchers who used a nonlinear oscillator equation to model the lift are (Hartlen & Currie, 1970) and Skop and Griffin (1975).…”

“…Bilgen et al [19,20] also presented the concept of replacing the wing trailing-edge devices with a morphing surface, capable of achieving continuous camber variations instead of rigid deflections. The morphing system was designed to replace the ailerons of a UAV, and thus used rapid, electrical actuation mechanisms.…”

This paper presents the results obtained from the numerical simulation and experimental wind tunnel testing of a morphing wing equipped with a flexible upper surface and controllable actuated aileron. The technology demonstrator is representative of a real aircraft wing tip section, and it was developed following a complex, multidisciplinary design process. The model was fitted with a composite material upper skin whose shape can be morphed, as a function of the flight condition, by four electrical actuators placed inside the wing structure. The optimizations were performed with the aim of controlling the extent of the laminar flow region, and the resulting shapes were scanned using high-precision photogrammetry. The numerical simulations were performed using Computational Fluid Dynamics (CFD) and included a model for predicting the laminar-to-turbulent flow transition over the entire wing surface. The analyses included cases with three aileron deflection angles and angles of attack situated within five degrees range. The CFD results were compared with infrared thermography measurements in terms of transition location, surface pressure measurements and balance loads measurements acquired during subsonic wind tunnel tests performed at the National Research Council Canada.

“…However, the authors showed few actuation of the composite. Another example is a micro aerial vehicle developed using macro fiber composite(MFC) (Bilgen et al 2007;Ohanian et al 2012). MFC is a piezoelectric composite material that was originally developed by NASA for morphing structures.…”

Researchers are seeking to create robots that could conform to non-uniform objects during handling and manipulation. High performance artificial muscles are the key factors that determine the capabilities of a robot. Twisted and coiled polymeric (TCP) muscle embedded in soft silicone skin solves some of the problems of soft robots in attaining morphed structure using low voltages, contrary to other technologies such as dielectric elastomer and piezoelectric. Furthermore, the TCP actuation system does not generate noise like pneumatic systems. The TCP embedded skin shows great promise for robotics to mimic the flexible appendages of certain animals. In this paper, we present experimental results on the effect of muscle placement and the thickness of the artificial skin on the actuation behavior, which can be used as a benchmark for modeling. We demonstrate the effect of three different skin thicknesses and three different muscle locations within the skin, by taking experimental deformation data from stereo camera. In general, two modes of actuations (undulatory and bending) were observed depending on the muscle placement, skin thickness, applied voltage, and actuation time. The thinner skin showed two-wave undulatory actuation in most cases, whereas the 4 mm skins showed mixed actuation and the 5 mm skins exhibited one-wave undulatory actuation. In all cases, the increase in voltage resulted in higher magnitudes of actuation. In addition, we showed consistent strain of the TCP muscles from 18 samples from two batches that produced an average strain of 22% (batch 1) to 20% (batch 2) with standard deviation of 2.5-1.8% respectively.
