Elliptical
Wing Problems
If so instructed by your teacher, print out a worksheet page for these problems. Open
the slide called Wing Geometry Definitions
(with text) and read the definitions.
The Spitfire (http://members.tripod.com/~F15JEagle2/spit.html) was renowned as a "small, graceful, elliptical-wing fighter, champion at air-to-air duals, and they were routinely dived at velocities approaching the speed of sound." An elliptically-shaped wing incurs the least drag. Let us assume the entire wing of the Spitfire is an ellipse with the major axis equal to the wingspan. Using a web site for the Spitfire V (http://www.sccs.swarthmore.edu/~dlevin/supermarine.html#spitfire) , we find wingspan and area data which can be used to determine the length of the minor axis.
