Testing Truck Aerodynamics
New emission regulations and higher fuel prices are driving a renewed interest in improving the aerodynamics of large trucks. NRC is helping small companies and truck manufacturers investigate truck aerodynamics and verify the efficacy of devices that reduce fuel consumption and greenhouse gas emissions. The tests are carried out in the largest of NRC's eight wind tunnels. The tunnel's balance was modified to enable it to take the truck's full weight, and four air-bearing plates were built to provide for a frictionless setup on which to rest the truck wheels. |
