Passively morphing trailing edge design for composite tidal turbine blades [PDF]

Composite Structures
Numerical simulations and lab-scale experiments are used to evaluate three passively morphing trailing edge designs for a composite tidal turbine blade. The designs include a closed trailing edge, an open trailing edge, and a corrugated trailing edge. It

Towards an industrial manufactured morphing trailing edge flap system for wind turbines [PDF]

, 2014
Several numerical studies in the past 10 years have shown big potentials for load reduction on MW turbines using distributed control for alleviation of the fluctuating loads along the blade span. However, the requirements by the wind turbine industry of robust actuator solutions where the strongest specifications mean no metal and electrical parts in ...

Experimental Aerodynamic Comparison of Active Camber Morphing and Trailing-Edge Flaps [PDF]

AIAA Journal, 2021
Unlike hinged flaps (for example, ailerons, elevators, and rudders), camber morphing devices vary camber distribution in a smooth and continuous way, resulting in aerodynamic efficiency improvements due to the absence of sharp changes in airfoil camber.

3D-Printed Wings with Morphing Trailing-Edge Technology

AIAA Scitech 2021 Forum, 2021
In recent years, various groups have attempted to improve aircraft efficiency using wings with morphing trailing-edge technology. Most of these solutions are difficult to manufacture or have limited morphing capability. The present paper outlines a research effort to develop an easy to manufacture, fully 3D-printed morphing wing.

Aerodynamic Performance of Morphing and Periodic Trailing-Edge Morphing Airfoils in Ground Effect

Journal of Aerospace Engineering, 2023
Applying fish bone active camber morphing to the wing-in-ground effect to improve the aerodynamic efficiency was investigated using computational fluid dynamics (CFD) at a Reynolds number of 320,000. Steady-static morphing was first carried out with Reynolds-averaged Navier–Stokes (RANS) equations in two dimensions for morphing start locations off (60%,
