"Wing shape" refers to the design and structure of wings in various flying organisms, including birds, insects, and aircraft. The shape can significantly influence flight performance, such as lift, drag, and maneuverability. Common wing shapes include elliptical, tapered, and delta, each serving different purposes based on the needs of the species or vehicle. In birds, for example, eagles have broad wings for soaring, while hummingbirds possess short, rounded wings for rapid hovering. In aviation, aircraft wings are designed to optimize fuel efficiency and stability, with variations like swept-back or straight wings tailored for specific flight conditions.
