Flügelende

Flügelende refers to the tip of a wing, specifically in the context of aviation and ornithology. In aviation, the wingtip is the outermost section of an aircraft's wing. This area is crucial for aerodynamic performance and can significantly influence factors like lift, drag, and stability. Wingtip devices, such as winglets or sharklets, are often attached to the Flügelende to reduce induced drag, which is a byproduct of lift generation. By disrupting the formation of wingtip vortices, these devices can improve fuel efficiency and reduce noise pollution.

In ornithology, Flügelende denotes the extremity of a bird's wing. This part of the wing is composed of specialized feathers called flight feathers, which are essential for propulsion and maneuvering during flight. The shape and structure of a bird's Flügelende vary widely depending on its species and flight style. For instance, birds of prey often have broad wings with separated primary feathers at the Flügelende, which aids in soaring and thermalling. In contrast, fast-flying birds like swifts have sharply pointed wingtips that minimize drag for high-speed flight. The study of Flügelende contributes to understanding avian aerodynamics and the evolution of flight.
