Theoretical performances of double Gurney Flap equipped the VAWTs [PDF]
INCAS Bulletin, 2012 A Gurney flap is simply a flat plate attached perpendicularly to the lower surface of an airfoil or wing trailing edge. A T-strip or double Gurney flap is attached to both the upper and lower surfaces.

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.

Active Management of Flap-Edge Trailing Vortices [PDF]
4th Flow Control Conference, 2008 The vortex hazard produced by large airliners and increasingly larger airliners entering service, combined with projected rapid increases in the demand for air transportation, is expected to act as a major impediment to increased air traffic capacity.

A Numerical Simulation on the Airfoil S833 Equipped with Flapping Trailing Edge Fringes [PDF]
Journal of Applied Fluid Mechanics, 2020 Design optimization has been increasingly investigated for an airfoil, aiming to reduce the vorticity in the wake and increase the aerodynamic performance. In the current work, a two-dimensional (2D) S833 airfoil equipped with a flapping fringe at the trailing edge has been studied using computational fluid dynamics (CFD) simulations.

On the Aeroelasticity of a Cantilever Wing Equipped with the Spanwise Morphing Trailing Edge Concept
Aerospace, 2023 This paper studies the aeroelastic behavior of a rectangular, cantilever wing equipped with the spanwise morphing trailing edge (SMTE) concept. The SMTE consists of multiple trailing edge flaps that allow controlling the spanwise camber distribution of a
