Laminar Airfoil Modification Attaining Optimum Drag Reduction by Use of Airfoil Morphing
Journal of Aircraft, 2010. Aerodynamic characteristics of the baseline and deformed airfoils have been investigated using a viscous–inviscid interaction method. It is shown that the leadingedge deformation is effective in reducing the drag at the offdesign angle of attack, in comparison with the baseline airfoil.

Robust Airfoil Design Optimization with Morphing Techniques
2015It is well known that morphing aircraft can change its shape for mission agility and control of flight. The main advantage of a morphing airfoil is its integrated shape control into an airfoil smart structure.

Skin design studies for variable camber morphing airfoils
Smart Materials and Structures, 2008This paper identifies the desirable attributes of a flexible skin of a morphing wing. The study is conducted using airfoil camber morphing as an example. The ideal flex-skin would be highly anisotropic, having a low in-plane axial stiffness but a high out-of-plane flexural stiffness.

A Single Actuator Mechanism for Airfoil Shape Morphing
Volume 5B: 42nd Mechanisms and Robotics Conference, 2018Presented in this paper is a single actuator mechanism for airfoil shape morphing. The said mechanism is designed as a linkage array that is driven by one actuator to provide multiple output points along the entire airfoil shape. This mechanism consists of two components, namely the shape adaptation linkage (SAL) and the connector linkage.

About the design of morphing airfoils under uncertainties
PAMM, 2015AbstractThe paper presents an optimization framework for dealing with morphing airfoils for helicopter rotor blades. With regard to the morphing strategy, a conformable camber line is considered to deal with variable flow conditions encountered in forward flight with the objective of increasing the aerodynamic performance on the advancing and ...

Concept for morphing airfoil with zero torsional stiffness
Thin-Walled Structures, 2015A morphing wing structure is presented which is designed to have zero torsional stiffness to minimise actuation requirements. The concept consists of carbon fibre reinforced plastic strips which are initially curved prior to being flattened and assembled into a grid-like structure in a heightened state of elastic strain energy.

Variable-stiffness skin concept for camber-morphing airfoils
Journal of Intelligent Material Systems and Structures, 2014Morphing airfoils promise advances in performance and efficiency when compared to conventional designs. However, the conflict of requirements between compliance and stiffness, which is characteristic of shape-adaptable structures, often leads to compromise-driven solutions. This article presents the concept of a variable-camber airfoil with adjustable

Concepts for Morphing Airfoil Using Novel Auxetic Lattices
2020In nature, the wings shape of a bird can be adjusted to be suitable for all flight situations providing optimal aerodynamic performance. Unfortunately, wings of traditional aircraft are optimized for only a few conditions, not for the entire flight envelope.

Airfoil Morphing Architecture Based on Shape Memory Alloys
Smart Materials, Adaptive Structures and Intelligent Systems, Volume 1, 2008The adaptive structures concept is of great interest in the aeronautical field because of the several benefits which can be accomplished in the design of future aircraft. Improvements in terms of aerodynamic efficiency, aero-elastic behaviour and manoeuvrability were proved by many international studies.
