A review of modelling and analysis of morphing wings

open access: yesProgress in Aerospace Sciences, 2018
Morphing wings have a large potential to improve the overall aircraft performances, in a way like natural flyers do. By adapting or optimising dynamically the shape to various flight conditions, there are yet many unexplored opportunities beyond current ...

Raptor wing morphing with flight speed [PDF]

open access: yesJournal of The Royal Society Interface, 2021
In gliding flight, birds morph their wings and tails to control their flight trajectory and speed. Using high-resolution videogrammetry, we reconstructed accurate and detailed three-dimensional geometries of gliding flights for three raptors (barn owl,Tyto alba; tawny owl,Strix aluco, and goshawk,Accipiter gentilis).

Comparative Aerodynamic Performance Analysis of Camber Morphing and Conventional Airfoils

open access: yesApplied Sciences, 2021
This paper aims to numerically validate the aerodynamic performance and benefits of variable camber rate morphing wings, by comparing them to conventional ones with plain flaps, when deflection angles vary, assessing their D reduction or L/D improvement.

Autonomous material composite morphing wing

open access: yesJournal of Composite Materials, 2023
Aeronautics research has continually sought to achieve the adaptability and morphing performance of avian wings, but in practice, wings of all scales continue to use the same hinged control-surface embodiment. Recent research into compliant and bio-inspired mechanisms for morphing wings and control surfaces has indicated promising results, though ...

Effects of dynamical chordwise retracting and stretching on the propulsive performance of a pure plunging flat plate

open access: yesAIP Advances, 2023
An innovative morphing scheme, i.e., dynamical chordwise retracting and stretching, has been proposed for flapping wings. Its aerodynamic effects have been investigated based on a plunging two-dimensional flat wing.
