winglets
Upturned aircraft tips
Winglets are the small, upturned tips at the ends of airplane wings.
They reduce drag by disrupting the vortices that form where high-pressure air beneath the wing meets low-pressure air above it, improving fuel efficiency.
The term also applies to any small wing or wing-like projection: The insect's winglets beat rapidly.
