Simulation of multi tip-sail winglet for drag reduction at mach 0.1 / Muhammad Ridzwan Ramli

The flying mechanism is unable to escape from the drag force, especially the drag force generated from the wingtip and trailing edge vortices due to the unbalanced pressure between the upper and lower surface. Then, Richard T. Whitcomb, the scientist at NASA Laboratory introduced the winglet structure, which is functional to reduce the wingtip and trailing edge vortices from the wing structure. However, the current winglet structure that has been installed to the flying mechanism still has room for improvement referred to the mother of nature. Birds usually display their characteristics on hovering and soaring longer in the air by extending their primary feathers.
