Rotational bistable mechanisms for morphing wings and beyond. [PDF]
Commun EngLow-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. Shape morphing enables aircraft to maximize aerodynamic performance but often requires complex system ...

Morphing wing optimization for steady level flight
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2016 This paper presents the basic results of the morphing wing planform optimization of an experimental unmanned air vehicle for minimum drag at steady level flight. The aerodynamic design tool that consists of the three-dimensional panel method, two-dimensional boundary layer solution and generalized reduced gradient method-based optimization is ...

Role of wing morphing in thrust generation
Theoretical and Applied Mechanics Letters, 2014 In this paper, we investigate the role of morphing on flight dynamics of two birds by simulating the flow over rigid and morphing wings that have the characteristics of two different birds, namely the Giant Petrel and Dove Prion.

Design of a composite morphing wing [PDF]
, 2019 Morphing aircraft components can increase the possibility of optimising the performance of an aircraft at various flight conditions. A morphing aircraft wing can change the wing shape to modify the lift and drag distribution on the wing surface, allowing the lift-to-drag ratio to be tailored to the desired performance.

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
