Abstract

The avian wings are characterized by smooth trailing-edge transformations adapting to the flow conditions for optimized flight performance. A novel bionic flap inspired by the avian wings is proposed. It features seamless gradual non-linear spanwise deformations at the trailing-edge. Comprehensive aerodynamic analyses are performed on a 3D S809 airfoil to ascertain the enhancements compared to the - baseline and conventional flap models. The investigation is conducted at the chord-based Reynolds number (Re) values of 0.5 and 1.0 million, with flaps deflected at (β): 10°, subjected to angles of attack (α): 0° & 6°. The influence of flow-incidence angle (α), and Reynolds number (Re) on the aerodynamic performance is carefully studied. The evolution of pressure- and flow- fields, surface-flow, skin-friction, and turbulence, provides insight of the significance of variable spanwise morphing. The proposed spanwise morphing exhibits delayed flow-separation and turbulence suppression over all flow-conditions, compared to the conventional flap.
