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.
