Witryna11 kwi 2024 · It was found that up to 10° angle of attack, the standard NACA0012 profile shows a higher lift-to-drag, whereas at 15° and 20° angle of attack, as the penguin wing one is 122% and 60.62% higher than the NACA0012 aerofoil. Implementation of scaling the geometric features of penguins for wing design applications is also simulated and … WitrynaHowever, for a viscous calculation form drag increases by 11% at α = 10 . The first experimental study of the wavy leading edge was carried out by [ 4 ], who built a scale model of a flipper using a NACA 0020 airfoil in wind tunnel testing with a Reynolds number range from 505,000 to 520,000.
