Why Do Airplane Wings Bend Upward?

The video explores the concept of winglets on aircraft wings, explaining their purpose in reducing aerodynamic drag caused by wing tip vortices. It delves into Bernoulli's principle and how pressure differences create lift and vortices. The video discusses the impact of vortices on aircraft performance and fuel efficiency, and presents solutions like winglets, which were first conceptualized by Richard Whitcomb. Winglets have been widely adopted since the 1980s, offering benefits such as reduced drag, improved fuel efficiency, and lower emissions. The video also touches on the historical context of winglets, tracing back to Frederick Lanchester's early ideas.
