Prototype Wing Design and Manufacturing for Reflexed Airfoil Morphing
Engineering ProceedingsThis paper presents the development of a novel morphing wing prototype with three camber-twist morphing flaps. Reflexed airfoil morphing is achieved by means of two chordwise degrees-of-freedom, thereby decoupling lift from the aerodynamic moment with ...
