Hi Gang, Last night my wife and I took the family to Exploration Place (Museum and Science Center) for an evening of fun and exploration. With Wichita being the "Air Capital of the World" of course they have a major exhibit dedicated to the science of flight. One of the exhibits has a mock up of a wind tunnel which uses liquid instead of air to show the effects of flow over various shapes. I have to admit I must have spent at least 30-45 minutes setting at this exhibit making different slope designs and looking at the effects made. It shows a perfect explanation of the boundary layer used in DS'ing and of the stagnant air area behind the hill. I was explaining what was going on to my son and it was not too long before there was a small crowd of people gathered around getting a little lesson in the phenomenon of DS. I wish Joe Wurts had been there to really give them (and me) a real lesson. If any of you ever make it to Wichita and would like to go look me up, we have season passes so I could get you in for free.
