Customizable nozzle pattern profiles can compensate for disturbances under the aircraft (such as prop wash and wingtip vortices
), environmental factors (such as crosswinds), and nozzle pattern modifications (such as partial boom shutoff for narrow swaths).
In 2013, a Piper Arrow crossing Lake Michigan was broken up in flight by the wingtip vortices
of a McDonnell-Douglas MD-80 on approach to Milwaukee.
These winglets reduce the drag caused by wingtip vortices
, thereby increasing fuel efficiency and boosting range.
It was applied to civilian aircraft by Met-Co Aire and is designed to reduce the strength of wingtip vortices
generated by high-pressure air under the wing moving outboard over the wingtip.
The Winglets reduce the drag caused by wingtip vortices
, the twin tornados formed by the difference between the pressure on the upper surface of an airplane's wing and that on the lower surface.
With flaps deployed, the air flowing off of the wing is more turbulent, causing the wingtip vortices
(wake turbulence) to dissipate faster.
Lanchester conceptualized wing end-plates to reduce the impact of wingtip vortices
, but modern commercial technology for this purpose traces its roots to pioneering NASA research in the 1970s.
It wasn't a KC-135 Iron Maiden or a wingtip-podded KC-130 complete with the associated wingtip vortices
. This was just a daytime Rhino tanker.
API's Blended Winglets are an addition to the aircraft wing tip which is designed to efficiently add effective wingspan, reduce the drag caused by wingtip vortices
to increase fuel efficiency and boost range.
By altering the airflow as it Leaves the wingtip, the extensions reduce wingtip vortices
and induced drag.
* Wingtip vortices
trailing a commercial jet can stretch up to 12.9 km (8 mi) long.
The narrow sweep reduces air friction across the wing surface, while the tapered wingtips eliminate wingtip vortices
that begin at higher speeds.
