Elastomer-based skins for morphing aircraft applications: Effect of biaxial strain rates and prestretch

Polymer Testing, 2022
There is an emerging trend in the morphing aircraft research where two or more morphing degrees of freedom are used on a wing which leads to the concept of polymorphing.

Integrated Morphing Strategy and Trajectory Optimization of a Morphing Waverider and Its Online Implementation Based on the Neural Network

IEEE Access, 2021
In previous studies, a variable-sweep-wing morphing waverider was proposed and its aerodynamic performance and dynamic model were provided. This morphing waverider can change sweep angle according to different flight scenario in order to achieve an ...

Effects of an Unsteady Morphing Wing with Seamless Side-Edge Transition on Aerodynamic Performance

Energies, 2022
This paper presents an unsteady flow analysis of a 3D wing with a morphing trailing edge flap (TEF) and a seamless side-edge transition between the morphed and static parts of a wing by introducing an unsteady parametrization method.

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.

Fluid–Structure Coupling and Aerodynamic Performance of a Multi-Dimensional Morphing Wing with Flexible Metastructure Skin

Aerospace, 2023
A multi-dimensional morphing wing skeleton mechanism is proposed with double-sided triangular pyramid units, which can realize continuous variable span-wise bend, span-wise twist, and sweep.

Conceptual Research on a Mono-Biplane Aerodynamics-Driven Morphing Aircraft

Aerospace, 2022
The operation of aircrafts with high aspect ratio wings is usually vulnerable to low-standard airports and bad weather. A new concept for a mono-biplane aerodynamics-driven morphing aircraft is proposed.

Comparison of Aerodynamic Characteristics of Morphing and Conventional Wings [PDF]

INCAS Bulletin
The present research investigates the advantages of a morphing versus a hinged flap. The morphing wing model is equipped with a morphing trailing edge, while the conventional wing has a hinged flap system.
