Rotational bistable mechanisms for morphing wings and beyond [PDF]

Communications Engineering
Low-energy-use morphing structures can greatly impact various engineering disciplines. In aeronautics, aircraft wings must adapt to diverse flight conditions to ensure optimally shaped wings for enhanced performance, maneuverability, and efficiency ...

A review of modelling and analysis of morphing wings [PDF]

Progress 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 proof-of-concept demonstrations.

Design and Analysis of MataMorph-3: A Fully Morphing UAV with Camber-Morphing Wings and Tail Stabilizers

Aerospace, 2022
Conventional aircraft use discrete flight control surfaces to maneuver during flight. The gaps and discontinuities of these control surfaces generate drag, which degrades aerodynamic and power efficiencies.

Raptor wing morphing with flight speed [PDF]

Journal 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

Applied 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

Journal 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 often

A New Architecture of Morphing Wing Based on Hyperelastic Materials and Metastructures With Tunable Stiffness

Frontiers in Mechanical Engineering, 2022
Morphing wings with the ability of shape changing may enlarge the flight envelop of air vehicles. This is particularly important for small-scale aircrafts demanding maneuverability and adaptability in dynamic environments.

Design of a Morphing Wingtip [PDF]

Journal of Aircraft, 2014
An initial design of a morphing wingtip for a regional jet aircraft is developed and evaluated. The adaptive wingtip concept is based upon a chiral-type internal structure, enabling controlled cant...

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

AIP 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.
