초록

A capped winglet comprising a helical portion having a smooth vertical curvature of 180°±approximately 20° from the plane of the unbounded end of a wing, and a generally planar cap contiguous with the helical portion of the winglet at the end of its curvature away from the wing, the cap having a free inboard end and a chord tapered toward the free end.

대표
청구항

The invention claimed is: 1. A blended winglet having a free inboard end having an outer wing end with leading and trailing edges defining a plane, said winglet comprising a vertically curved, helical portion having a smooth vertical curvature of 180°±approximately 20° from the plane of the outer wing end, wherein said helical portion of said winglet has substantially parallel, aft-extending leading and trailing edges and a longitudinal axis substantially parallel to the plane of the wing adjacent the winglet. 2. The winglet of claim 1,...
