For an interesting way to kill an hour:
1) Get a picture of a sprint car mid-corner, preferably from up top
2) Measure the yaw angle
3) Make a rough measurement of the size of the wing and the endplates
4) Make a little scale model of the wind and endplates (cardboard works
fine)
5) Glue it to a chunk of cardboard at the same yaw angle as you measured in
step 2
6) Look at the wing from the perspective of the air (ie, 0 degrees yaw)
7) Notice that the endplates completely mask the actual airfoil section.
8) Realize then that the airfoil section sees no real airflow
9) Ponder what the REAL purpose of this wing is. *
(*for a clue, look at a picture of a sprint car mid-corner as taken from
the front. See something odd?)
