Aerodynamic and aeroacoustic characteristics of a bionic morphing flap
Energy Reports, 2023 Birds adapt to the changing flight conditions by performing intricate feather-movements to manipulate the airflow. The avian wings often undergo seamless transformations at the trailing-edge to achieve camber-reflexes for extended flight envelope.

Aerodynamic and Aeroacoustic Performance of Airfoils Fitted with Morphing Trailing-edges [PDF]
2018 AIAA/CEAS Aeroacoustics Conference, 2018 Experimental and numerical studies of a simple NACA 0012 airfoil fitted with two different flap profiles were successfully carried out to characterize their aerodynamic and aeroacoustic performance. The airfoil was tested with two flap configurations with different flap camber and a flap deflection angle of = 10.

Adjoint-based optimization of flapping plates hinged with a trailing-edge flap
Theoretical and Applied Mechanics Letters, 2015 It is important to understand the impact of wing-morphing on aerodynamic performance in the study of flapping-wing flight of birds and insects. We use a flapping plate hinged with a trailing-edge flap as a simplified model for flexible/morphing wings in ...

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.
