Performance Testing in DTF Wind Tunnel No. 8

2004-11-30
2004-01-3549
Since being commissioned in 2001, the aero-acoustic wind tunnel at DTF, Wind Tunnel 8 (WT8) has been used to conduct a wide variety of tests. In 2003 alone, over 5250 hours of aerodynamic and aero-acoustic testing were run on over 2000 test articles, including commercial cars, trucks and racing vehicles. Additionally, more unique test articles such as solar cars, motorcycles, Olympic sleds, and others have also been recently tested. The demand for WT8 is driven by the fact that it is among the quietest wind tunnels in the world and one of a very small number of facilities that combines aerodynamic, aero-acoustic, and climatic capabilities in one facility. To enhance WT8's ability to meet the ever-increasing demands of the testing community, and the Motorsports community specifically, an effort was recently initiated to optimize and document the repeatability of aerodynamic force measurements in this tunnel.

The Driveability Test Facility Wind Tunnel No. 8

The Sverdrup Driveability Test Facility (DTF) represents a new type of partnership in automotive testing between a supplier (Sverdrup Technology) and an original equipment manufacturer (Ford Motor Company). The facility was designed and built by Sverdrup to Ford's specifications. It is also operated and maintained by Sverdrup, with Ford as its “anchor” client under a long-term lease-back arrangement. Test time that goes unused by Ford is made available to other customers. Wind Tunnel 8 (WT8) is one of the test facilities within the DTF, which includes two other climatic wind tunnels and several supporting test cells. This tunnel combines aerodynamic, acoustic, climatic, and powertrain capabilities within one facility. The airline was optimized during the design stage for the competing requirements of excellent flow quality, very low background noise, and climatic capability.

The Ford Motor Company Rolling Road Wind Tunnel (RRWT) is a state-of-the-art aerodynamic wind tunnel test facility in Allen Park, Michigan. The RRWT has operated since January 2022 and is designed for passenger and motorsport vehicle development. The test facility includes an office area, three secure customer vehicle preparation bays, a garage area, a vehicle frontal area measurement system, and a full-scale ¾ open jet wind tunnel. The wind tunnel features an interchangeable single belt and 5-belt Moving Ground Plane (MGP) system with an integrated 6-component balance, a two-position nozzle, boundary layer removal systems, and two independent flow traverse systems. Each flow traverse has a large horizontal box beam and vertical Z-strut that can position the flow traverse accurately within the test volume.

Transitioning Automotive Testing from the Road to the Lab

The importance of the automotive test facility has increased significantly due in large part to continuous pressure on manufactures to shorten product development cycles. Test facilities are no longer used only for regulatory testing, or development testing in which the effects of small design changes (A-to-B testing) are determined; automotive manufacturers are beginning to use these facilities for final design validation, which has traditionally required on road testing. A host of resources have gone into the design and construction of facilities with the capability to simulate nearly any environment of practical importance to the automotive industry. As a result, there are now a number of test facilities, and specifically wind tunnels, in which engineers can test most aspects of a vehicle's performance in real-world environments.
