Bio-inspired designs have been serving as a great inspiration for Aerodynamists for the past
several decades. The biological features of each species have evolved through generations …

Biomimetics is an interdisciplinary field of science that deals with the analysis and
systematic transfer of biological insights into technical applications. Moreover, the …

Since the inception of fibre-reinforced composite materials, they have been widely
acknowledged for their unparalleled weight-to-performance ratio. Nonetheless, concerns …

Physical surface modification is an approach that has been investigated over the last
decade to reduce bacterial adhesion and improve cell attachment to biomaterials. Many …

The Anthropocene is the new geological epoch, characterized by the accelerating global
influence of humankind and the impending point of no return on environmental changes. In …

Five bionic multi-tip winglet configurations, inspired by basic feather shapes and wingtip
postures of birds, were designed to suppress the tip-vortex structures around their wingtips …

Purpose Winglets play a major role in saving fuel costs because they reduce the lift-induced
drag formed at the wingtips. The purpose of this paper is to obtain the best orientation of the …

In this paper, a numerical analysis of a biomimetic unmanned aerial vehicle (UAV) is
presented. Its wings feature three grids at the tip similar to the primary feathers of birds in …

Wingtip vortices generated from aircraft wingtips, as a result of the pressure differential at the
wingtip, constitute a major component of the total drag force, especially during take-off and …

Experiments on the relative merits and demerits of slotted wingtips mimicking a bird's
primary feathers have been performed. The real emargination length of feather tips, their …
