DOWNWARD FACING WINGLETS

G R Mohan | 12:05 AM | | | | | Best Blogger Tips
Aircraft designers have traditionally used winglets as a means to reduce induced drag and save on consequent fuel burn aka operating costs. Over the years several designs have emerged and the classic end plates and winglets are common in Boeing and airbus models. General aviation aircraft on the other hand have more innovative designs of winglets to enhance operational cost benefits.
While an equivalent increase in wingspan would be more effective than a winglet of the same length, the bending force becomes a greater factor.  Typically, a three-foot winglet has the same bending force as a one-foot increase in span, yet gives the same performance gain as a two-foot wing span increase.  For this reason, most designers have concentrated their efforts in winglets designs to reduce drag.
