Engineering marvels have led to the design and build the wing-in-ground-effect (WIG) crafts to fill the gap between ships and aircraft as a new opportunity for transportation. One of the most significant issues in WIG crafts design is drag and lift force when the craft starting to plane. In this study, living nature has been used as an instrument to solve the mentioned problem. There are various ways in nature to reduce drag force in fluid flow, such as the evidence in the movements of fish, sharks and dolphins, the skin of fast-swimming sharks is covered by micro-riblets that assist them to move fast. In this research, by using Computational Fluid Dynamics software ANSYS CFX the effects of riblets on the wing in ground effect were examined. A Clark-Y wing was simulated in simulation software at various Reynolds number and drag and lift coefficients are captured. The results reveal that by using the riblets on the wings in the ground 7 % drag reduction and 6% increase in lift force can be achieved.
