Conceptual study of a morphing winglet based on unsymmetrical stiffness [PDF]
, 2016 Morphing technology has the potential to increase aircraft performance. Among the morphing technologies, the morphing winglet is a promising solution due to its small size and large effect on the aerodynamics. Morphing winglets have to carry the spanwise

The symmetry of wings and sails [PDF]
, 2019 All of the principal items of flight performance involve steady flight conditions and equilibrium of the airplane. The same is true for the performance of boards and boats when sailing and foiling.

Aerodynamic Optimization of Wing by Camber Morphing using Cfd
International Journal of Engineering and Advanced Technology, 2020 This paper presents the CFD analysis of the 2-Dimensional NACA0012 airfoil carried out for identifying its aerodynamic coefficients (Lift and Drag coefficients), then further implementing morphing technology on the same two-dimensional NACA0012 airfoil, again carrying out CFD analysis to determine its aerodynamic coefficients (Lift coefficient (CL) and

Perspectives on Highly Adaptive or Morphing Aircraft [PDF]
, 2009 The ability to adapt to different flight conditions has been fundamental to aircraft design since the Wright Brothers first flight. Over a hundred years later, unconventional aircraft adaptability, often called aircraft morphing has become a topic of ...

Effect of Graphene Addition on Shape Memory Behavior of Epoxy Resins [PDF]
, 2011 Shape memory polymers (SMPs) and composites are a special class of smart materials known for their ability to change size and shape upon exposure to an external stimulus (e.g. light, heat, pH, or magnetic field).

The effect of twist morphing on aerodynamic performance of finite wing at low Reynolds number [PDF]
EPJ Web of ConferencesThis study experimentally investigates the effect of twist morphing on the aerodynamic characteristics of a finite wing at low Reynolds numbers (Re). As the base model, a NACA 0018 airfoil with an aspect ratio of 4 is used.

Development of Variable Camber Morphing Airfoil Using Corrugated Structure
Journal of Aircraft, 2014 This paper describes the development and the wind tunnel test of a variable geometry morphing airfoil using corrugated structures. Proof-of-concept study of a morphing wing with corrugated flexible seamless flap-like structure is verified by finite element analysis, and a prototype is manufactured using carbon fiber reinforced plastics.
