[Pat Major]

The wind tunnel is at the Chrysler Technology Center in Auburn Hills Mi. Interesting story we were told: During the initial installation of the tunnel they could not get the scales that the car’s tires sit on to stabilize as they were trying to calibrate them. They resolved the problem by turning off the heating and cooling system to the room, they found that the air flow and change in pressure was the reason the scales would not stabilize. That was not the only issue; they also found they were picking up the vibrations from semi trucks as they were traveling the roads around the Tech Center. Accuracy…..quality…..they don’t mess around. The tour was very impressive for students and adults. We did not stand in the tunnel while it was in operation. We did walk the whole circuit and test the unbelievable acoustics
