Pressurized Morphing Wing Structures
53rd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference<BR>20th AIAA/ASME/AHS Adaptive Structures Conference<BR>14th AIAA, 2012The combination of structural material and fluid pressure may result in a morphing structure with integrated shape-change and stiffness functions. In a cellular arrangement, distributed actuation, high control fidelity and a multitude of morphing shapes can also be achieved.

High Authority Morphing Structures
Aerospace, 2003Recent advances in actuation technology and multifunctional materials have presented a unique opportunity to develop structures that have the ability to morph to a variety of shapes while under significant load constraints. One of the many applications of these “high-authority” systems is for morphing air wings for control and drag reduction.

A bio-inspired, active morphing skin for camber morphing structures
Smart Materials and Structures, 2015In this study, one kind of developed morphing skin embedded with pneumatic muscle fibers (PMFs) was manufactured and was employed for camber morphing structures. The output force and contraction of PMF as well as the morphing skin were experimentally characterized at a series of discrete actuator pressures varying from 0.15 to 0.35 MPa.

Probabilistic Composite Morphing Structure Simulation
50th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2009Composite simulation software has been enhanced to compute the shape changes and durability of piezoelectrically controlled airfoil structures. The GENOA Progressive Fracture Analyzer (PFA) is now developed to simulate and validate probabilistic design methodology to identify composite shape changes as well as damage progression due to piezoelectric ...

Shape morphing hinged truss structures
Smart Materials and Structures, 2009Truss structures are widely used for the support of structural loads in applications where minimum mass solutions are required. Their nodes are normally constructed to resist rotation to maximize their stiffness under load. A multi-link node concept has recently been proposed that permits independent rotation of tetrahedral trusses linked by such a ...

Morphing Blade Fluid-Structure Interaction
53rd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference<BR>20th AIAA/ASME/AHS Adaptive Structures Conference<BR>14th AIAA, 2012Wind tunnel tests have been conducted on a 1.3 m chord NACA 63-418 blade section fitted with an adaptive trailing edge flap. The 20% chord flap has an aramid honeycomb core covered with a silicone skin and is actuated using servo motors. The honeycomb core has a high stiffness in the thickness direction but is compliant in flapwise bending.

Feasible Conceptual Design of Morphing Structures
22nd AIAA/ASME/AHS Adaptive Structures Conference, 2014rst level consists of a morphing wing model specic to the concept that is investigated. This is used to identify the types of morphing in the concept and generate the corresponding morphing constraints for the second level. The second level is a generic morphing aeroelastic optimisation framework that is used to optimise the morphing parameters and nd ...

On the Experimental Characterization of Morphing Structures
2018A major difficulty in the design of morphing devices for aircraft wings is to reach an adequate compromise between high load-carrying capacity to withstand aerodynamic loads and sufficient flexibility to achieve better aerodynamic performance. Such counteracting and demanding targets lead to an increased structural complexity whose experimental ...
