What do split Scimitar winglets do?

Winglets help to reduce drag By producing a vortex or mini-tornado effect at the end of the wing, this drag is reduced. This is what winglets are designed to do. As a result, the aircraft’s fuel consumption reduces, and as we know airlines are always trying to be as fuel-efficient as possible.

How do split winglets work?

How the split winglets work. Winglets are added to the end of a plane’s wings to reduce drag and ultimately enable more efficient flight. They work by reducing a process known as vortex drag, caused by different air pressures converging at the tips of each wing and slowing the aircraft down.

Do all 737s have winglets?

In fact 85% of all new 737s are now built with winglets, particularly the 800 and 900 series and of course all BBJs. It comes down to cost versus benefits.

Which winglet is best?

The shark fin-alike winglet was overall the most efficient design, followed shortly by the famous blended design found in many mid-sized airliners. The worst performing designs were surprisingly the fenced and spiroid designs, which had efficiencies on par with the wing without winglet.

What are blended winglets?

Blended winglets are upward-swept extensions to airplane wings. They feature a large radius and a smooth chord variation in the transition section. This feature sacrifices some of the potential induced drag reduction in return for less viscous drag and less need for tailoring the sections locally.

Who invented winglets?

engineer William E. Somerville
Wing end-plates In the United States, Scottish-born engineer William E. Somerville patented the first functional winglets in 1910. Somerville installed the devices on his early biplane and monoplane designs. Vincent Burnelli received US Patent no: 1,774,474 for his “Airfoil Control Means” on August 26, 1930.
