Abstract :A comprehensive review of sharkskin-inspired surfaces and riblet structures (also known as denticles) is conducted which is motivated by the desire to enhance aerodynamic efficiency and sustainability in modern aviation. Inspired by natural sea creatures like sharks, biomimetic surface alterations aim to reduce drag by altering the flow behavior around aerodynamic surfaces. This approach has gained increasing attention as a promising method for improving aircraft performance, particularly due to its direct impact on reducing fuel consumption. Following the literature review, a simple case study is presented to depict the suitability of riblet applications. The results demonstrated that riblet structures (denticles) can lead to significant drag reduction and, hence enhanced aerodynamic performance. These surface modifications not only can benefit conventional aircrafts but also offer a great promise for novel air vehicles, including unmanned aerial systems, electric aircraft, and urban air mobility platforms, where efficiency and extended range are critical. These findings highlight the potential of biomimetic surface designs as an effective solution in the development of next-generation aerospace systems.
