Summary[edit]

Description
English: The effect of the installation of Winglets on the wing of a Boeing 737 NG. The color represents the amount of rotation present in the air immediately behind the trailing edge. Specifically, the data represents the quantity with values ranging from
 
+15 (anti-clockwise)
to
 
-15 (clockwise)

Data measured at M=0.78 & lift coefficient=0.5 . The winglet-less measurement was made at a higher angle of attack (2.55°) than the winglet case (2.43°). Quantitative data is loosely interpreted from a Boeing magazine publication.

It can be seen that the presence of the winglet distributes the vorticity more evenly along the outer part of the wing.

This diagram was created with Inkscape…important.
This SVG diagram contains embedded raster graphics.[1] Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics.
Note: This template is only supposed to be used if the SVG file mixes vector and raster graphics. If the SVG file only contains raster graphics {{FakeSVG}} is supposed to be used. See also {{TopoSVG}}.
