Elliptical
Wing
Answers
 State the lengths
of the major and minor axes of the elliptical wing Major
axis = 11.2m; minor axis = 2.56m.
 Use this information
to write an equation of the ellipse (in standard form, assuming a center
at {0,0}). ( x / 5.6 )^{2 }+
( y / 1.28 )^{2} = 1.
 Sketch the ellipse
on x, y axes with the center of the ellipse at the origin. Label the
coordinates of the extremities of the major axis (wing tips) and minor
axis.
 How is the minor
axis related to chord length? The minor
axis is equal to the maximum wing chord length = 2.56 m.
 Is the chord length
constant? No, it varies decreasing to zero
at the wing tips.
 What is the chord
length 1 m from the ellipse's wing's center? 2.52m.
2.8 m from the center? 2.22m.
5 m from the center? 1.15m.
 Using the chord
length 2.8 m from the center, compute an aspect ratio. 5.05.
