PERFORMANCE-ENHANCING WINGLET SYSTEM AND METHOD

摘要

A winglet system (98) for an aircraft wing (50) may include an upper winglet (100) and a lower winglet (200) mounted to a wing tip (56). The lower winglet (200) may have a static position when the wing (50) is subject to a ground static loading. The lower winglet (200) may be configured such that upward deflection of the wing (50) under an approximate 1-g flight loading causes the lower winglet (200) to move from the static position to an in-flight position and resulting in a relative span increase of the wing (50).
