An elliptical wing is a wing planform shape, first seen on aircraft in the 1930s, which minimizes induced drag. WING "ESPN 1410" is a commercial AM radio station in Dayton Ohio operating with 5000 watts at 1410 kHz with studios offices and transmitter located on David A planform or Plan view is a vertical Orthographic projection of an object on a horizontal plane like a Map. In Aerodynamics, lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, is a drag force that occurs whenever Elliptical taper shortens the chord near the wingtips in such a way that all parts of the wing experience equivalent downwash, and lift at the wing tips is essentially zero, improving aerodynamic efficiency due to a greater Oswald efficiency number in the induced drag equation. In reference to Aircraft, chord refers to the distance between the leading edge and trailing edge of a Wing, Horizontal stabilizer or Vertical stabilizer
The elliptical wing has seen only limited use, mainly because :
- the compound curves involved are difficult and costly to manufacture,
- the pure elliptical shape as an ideal planform may be a myth. A truncated ellipse, same span, same area, has the same induced drag. Trapeze planforms with 0. 4 or 0. 5 taper ratio are induced drag equivalent, too.
- furthermore, the wing's uniform lift distribution causes the entire span of the wing to stall simultaneously, potentially causing loss of control with little warning. In the context of a Fluid flow relative to a body the lift force is the component of the Aerodynamic force that is Perpendicular to the flow For other uses see Stall. In Aerodynamics, a stall is a sudden reduction in the lift forces generated by an Airfoil To compensate, aircraft such as the Supermarine Spitfire used a modified elliptical wing with washout, though such compromises increase induced drag and reduce a wing’s efficiency. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout Washout refers to a feature of wing design to deliberately reduce the lift distribution across the span of the Wing of an Aircraft. Note, though, that the typical tapered wing planform has to employ more washout than the elliptical planform wing to see similar stall performance, which puts the tapered wing at a disadvantage.
Few aircraft have used elliptical wings, and even fewer have seen mass production, most in the 1930s and 40s. Mass production (also called flow production, repetitive flow production, series production, or serial production) is the production of The 1930s were described as an abrupt shift to more radical and conservative lifestyles as countries were struggling to find a solution to the Great Depression. The 1940s decade ran from 1940 to 1949 Events and trends The 1940s was a period between the radical 1930s and the conservative 1950s which also leads the period to be The English Supermarine Schneider Trophy racers of the early and mid 1930s were some of the most successful designs, and were the predecessors to the later Spitfire fighters. England is a Country which is part of the United Kingdom. Its inhabitants account for more than 83% of the total UK population whilst its mainland Supermarine was a British aircraft manufacturer that become famous for producing a range of sea planes and the legendary Supermarine Spitfire fighter The Coupe d'Aviation Maritime Jacques Schneider " (commonly called Schneider Trophy, or prize or cup was a prize competition for Seaplanes Announced by The 1930s were described as an abrupt shift to more radical and conservative lifestyles as countries were struggling to find a solution to the Great Depression. The German Heinkel He 70 of the early 1930s was a fast mail plane and reconnaissance bomber, and the predecessor to the Heinkel He 111 bomber, early models of which used an elliptical wing. Nazi Germany and the Third Reich are the common English names for Germany under the regime of Adolf Hitler and the National Socialist German Workers WikipediaWikiProject Aircraft.

Please see WikipediaWikiProject Aircraft/page content for recommended layout The LP1 from Algie Composite Aircraft uses a true elliptical wing planform, with higher aspect ratio than the Spitfire. Algie Composite Aircraft is an Aircraft kit company that is developing the LP1 kit In addition, several contemporary aircraft used a more conventional wing with elliptical wingtips in an attempt to gain some benefits without the added cost, but the aerodynamic benefit was found to be minimal.
