Design and aerodynamic analysis of an airfoil with a bioinspired leading edge device for stall mitigation at low Reynolds number operation
… attached to one of the hand digits of a bird's wing. The alula is extended by birds at high incidence angles and has been shown to improve the stall parameters of the wings. In this study, a series of wind tunnel experiments are performed to quantify the effect of various deployment …

An experimental study of a leading-edge alula-inspired device (LEAD) for moderate aspect ratio wings at low Reynolds numbers
… phenomena such as stall and flow separation. Birds mitigate those limitations by adapting their wings and feather shapes during flight. Equipped with a set of small feathers, known as Alula, located near the leading edge and covering 5% to 20% of the span, bird wings can sustain the lift …

Understanding the Structure of Wing Tip Vortices of Bio-Inspired Winglets
… of a bio-inspired winglet design based on bird feathers were tested in a low-speed wind tunnel. Particle image velocimetry (PIV), was used to study the flow field at two planes aft of the wing as the wing tip vortices developed downstream. These were time-dependent, stereoscopic particle …
