Shape Morphing Using PDE Surfaces [PDF]
, 2006 YesA methodology for shape morphing using partial differential equation (PDE) surfaces is presented in this work. The use of the PDE formulation shows how shape morphing can be based on a boundary-value approach by which intermediate shapes can be ...

Near Stall Unsteady Flow Responses to Morphing Flap Deflections
Fluids, 2021 The unsteady flow characteristics and responses of an NACA 0012 airfoil fitted with a bio-inspired morphing trailing edge flap (TEF) at near-stall angles of attack (AoA) undergoing downward deflections are investigated at a Reynolds number of 0.62 × 106 ...

Comparative Aerodynamic Performance Analysis of Camber Morphing and Conventional Airfoils
Applied 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.

Comparison of Aerodynamic Characteristics of Morphing and Conventional Wings [PDF]
INCAS BulletinThe 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.

Aerodynamic and Aeroacoustic Analysis of a Harmonically Morphing Airfoil Using Dynamic Meshing
Acoustics, 2021 This work explores the aerodynamic and aeroacoustic responses of an airfoil fitted with a harmonically morphing Trailing Edge Flap (TEF). An unsteady parametrization method adapted for harmonic morphing is introduced, and then coupled with dynamic ...

Aerodynamic and performance characteristics of a passive leading edge Kruger flap at low Reynolds numbers [PDF]
, 2012 An experimental and numerical study was performed on a Clark Y aerofoil with a 10% chord leading edge Kruger flap to examine its aerodynamic performance at Reynolds numbers of 0.6 × 106, 1 × 106, and 1.6 × 106, to help to identify the forces and ...
