However, the design of a typical airplane also creates induced drag, because the higher pressure air meets the lower pressure at the wingtips, creating a vortex behind the aircraft as it flies ...

T he Boeing 767-300ER has long been a key part of medium- and long-haul operations for airlines across the world. It belongs ...

Depending upon various parameters such as the Reynolds number, the surface roughness, or the presence of marine growth, etc., the drag coefficient for helical strakes typically varies from about 1 ...

That third component is induced drag. With the advent of winglets, the aircraft is able to weaken the strength of wingtip vortices and, more important, cut down on induced drag along the whole wing.

This backward flow combines with the upward roll from under the wing to form a vortex. ... cause lift-induced drag, lowering the ... 20,000 winglets on 10,000 airplanes (900 bizjets ...

Aerodynamicists reveal link between fish scales and aircraft drag City, University of London's Professor Christoph Bruecker and his team have transferred the idea of fish scales to arrays of bio ...

This is known as induced drag. Wing shape can be designed to minimise this effect, for example, the beautiful elliptical wings of the second world war Spitfire fighter plane.

Minix claims its design can save as much as 6% on an aircraft's energy costs. For a commercial Boeing 747, that equates to a saving of around 600,000 gallons of fuel - per year, per aircraft. Food ...
