In the chord analysis applet, you're able to experiment with changing the length of the airfoil.
Rather than simply changing the length, what you'll do by shrinking the airfoil is start to
turn it into a circle. By expanding the length, you'll turn it back into the familiar airfoil
One interesting thing to do is to shrink the chord length to the minimum, and see how the
streamlines start to run around the circle
Warning: This applet is computationally intensive. On most modern computers, the time it takes
to update after you click is under one-tenth of a second, but on more outdated computers,
it may take as much as five seconds. Please don't click again, thinking nothing happened,
as the applet is recomputing the streamlines.
When the applet loads, you will see an airfoil with many lines around it - the
streamlines. The airfoil which appears by default is representative of
a modern airfoil. To look at an airfoil representative of that on the
Wright Brothers flier, click the "early" button. If you decide
you'd prefer to go back to a more modern airfoil, click the "modern" button.
Using the two arrows pointing to the left and right, you can shrink and raise the chord length,
