Testing

The team is finally done with their wooden models and has been testing them in the wind tunnel. They have been testing last week. There have been some inconsistent results with the wind tunnel and they are working on making them better. The wind tunnel is a devise that the team uses to test the drag and aerodynamics on the models. The wind tunnel has a small grain bin fan that draws air through the tunnel. The fan was donated by one of our great sponsors Stanek Brothers Farms. We give a special thanks to them. It roughly runs at a speed of 85mph. The tunnel is made out of Lexan glass. It is also sealed tight to insure that they are able to get a quality reading from the force sensor. The force sensor is the devise that measures the force on the model. It is attached to a scientific calculator which shows the results. As the fan draws air through the tunnel it pulls on the model and the more the model is aerodynamically the less drag which in turn puts less force on the gage. This is important in making the car. The less force on the car allows the batteries to use less power. In the coming weeks the team will be working on making prototypes of the cars.
