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.
