WINGTIP DEVICES

Wingtip devices on derivative airplanes can improve performance by reducing induced drag. Selection of the
wingtip device depends on the specific situation and the airplane model.

Boeing 747-400

747-400.
The 747-400 commercial airplane needed a significant span increase to meet the range requirement. However, structural constraints prevented the total span increase, so a combination of winglet and span increase was used.

767-400

767-400.
Following a business-case study of the benefits of adding winglets or increasing wingspan, the 767-400 program chose a span increase in the form of a raked tip.

BBJ

BBJ and 737-800.
The wingtip device for the BBJ and 737-800 commercial airplane involved a retrofit of existing wings. The blended winglet was selected because it required minimal changes to the wing structure and provided improved aesthetic appeal for the BBJ.

737-800

Drag Reduction of Wingtip Device

MD-11

MD-11.
The MD-11 program chose a winglet based on wingspan constraints and minimum structural weight.

KC-135

KC-135.
The U.S. Air Force and the National Aeronautics and Space Administration conducted a winglet development program in 1978 to understand how winglets could improve performance.
