ODU chose a single belt rolling road system developed by MTS for use in the 14x22. The test vehicle “rides” on top of the stainless steel belt simulating the vehicle passing over the road surface. The MTS steel belt technology is preferred due to its top speed and the flat reaction surface for the tires providing correct aerodynamic interaction at the tire to ground interface. Downforce is measured using MTS’ “through the belt” load cell technology. The stainless steel roadway is 23’ long by 7.9’ wide and capable of a top speed of 180 mph. The turntable has ±10° of yaw range. This system provides the most precise road and track simulation available in a wind tunnel today.
In addition to the facility boundary layer removal system, a secondary boundary layer removal system will be integrated into the rolling road module just upstream of the belt to pull off the maximum amount of the boundary layer.
