Numerical Investigation of an NACA 13112 Morphing Airfoil [PDF]

open access: yesBiomimetics
This article presents a numerical study on the 2D aerodynamic characteristics of an airfoil with a morphed camber. The operational regime of the main rotor blade of the IAR 330 PUMA helicopter was encompassed in CFD simulations, performed over an angle ...

Effect of Coupled Wing Motion on the Aerodynamic Performance during Different Flight Stages of Pigeon [PDF]

open access: yesCyborg and Bionic Systems
Birds achieve remarkable flight performance by flexibly morphing their wings during different flight stages. However, due to the lack of experimental data on the free morphing of wings and the complexity of coupled motion in aerodynamics studies, the ...

Characterization of Wing Kinematics by Decoupling Joint Movement in the Pigeon [PDF]

open access: yesBiomimetics
Birds have remarkable flight capabilities due to their adaptive wing morphology. However, studying live birds is time-consuming and laborious, and obtaining information about the complete wingbeat cycle is difficult.

Towards an industrial manufactured morphing trailing edge flap system for wind turbines [PDF]

open access: yes, 2014
Several numerical studies in the past 10 years have shown big potentials for load reduction on MW turbines using distributed control for alleviation of the fluctuating loads along the blade span. However, the requirements by the wind turbine industry of robust actuator solutions where the strongest specifications mean no metal and electrical parts in ...

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

open access: yesEnergies, 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.

Experimental Aerodynamic Comparison of Active Camber Morphing and Trailing-Edge Flaps [PDF]

open access: yesAIAA Journal, 2021
Unlike hinged flaps (for example, ailerons, elevators, and rudders), camber morphing devices vary camber distribution in a smooth and continuous way, resulting in aerodynamic efficiency improvements due to the absence of sharp changes in airfoil camber.

The Effects of a Morphed Trailing-Edge Flap on the Aeroacoustic and Aerodynamic Performance of a 30P30N Aerofoil

open access: yesAcoustics, 2022
This paper presents initial results on the aeroacoustic and aerodynamic effects of morphing the trailing-edge flap of the 30P30N aerofoil, over five flap deflections (5–25°), at an 8° angle of attack and a Reynolds number of Re=9.2×105.
