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.

Roll Control of Morphing Aircraft with Synthetic Jet Actuators at a High Angle of Attack

open access: yesApplied Sciences, 2021
Flow separation and dynamic stall occurring at a high angle of attack will lead to difficulty in control and maneuverability for morphing aircraft. This study proposes a novel active flow control technology using a synthetic jet actuator for the roll ...

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

open access: yesAerospace, 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.

Conceptual-level evaluation of a variable stiffness skin for a morphing wing leading edge [PDF]

open access: yes, 2019
A morphing leading edge produces a continuous aerodynamic surface that has no gaps between the moving and fixed parts. The continuous seamless shape has the potential to reduce drag, compared to conventional devices, such as slats that produce a discrete
