Arnold Engineering Development Complex

Arnold Engineering Development Complex (AEDC) (Arnold Engineering Development Center before July 2012) located at Arnold Air Force Base, Tennessee is a ground-based flight test facility operated by the Air Force Test Center.

Mission statement
The AEDC mission is to:
 * Test and evaluate aircraft, missile and space systems and subsystems at the ﬂight conditions they will experience during a mission;
 * Conduct a research and technology program to develop advanced testing techniques and instrumentation and to support the design of new test facilities;
 * Maintain and modernize the center’s existing test facilities.

History
Originated in 1951, the center operates 58 aerodynamic and propulsion wind tunnels, rocket and turbine engine test cells, space environmental chambers, arc heaters, ballistic ranges, and other specialized units. Currently, AEDC's prime contractor is the Aerospace Testing Alliance.

The center has helped to develop most aerospace systems in the U.S. government's inventory, including the Atlas, Titan, Minuteman and Peacekeeper ICBMs, the Space Shuttle, space station, and Projects Mercury, Gemini and Apollo.

It is named for General Henry "Hap" Arnold, the father of the US Air Force and an air power visionary. The University of Tennessee Space Institute (UTSI) is located adjacent to AEDC.

The center lies near Manchester, Tennessee and Tullahoma, Tennessee, and occupies much of the site of the former Camp Forrest, a U.S. Army base and World War II POW camp. It is unique in that the majority of the workforce are contract personnel, with a small contingent of active-duty assigned.

Environmental Issues
Several areas of the facility are contaminated by substances including polychlorinated biphenyls (PCBs) and volatile organic compounds and spills of jet and rocket fuel, chlorofluorocarbon solvents, nitric acid and other materials. PCBs from the site have been detected in local creeks, in the water, sediment and in fish.

The site was proposed for addition to the Superfund National Priorities List in August 1994 though, as of May 2010, the site has not been added to the NPL. The Environmental Protection Agency believes that human exposure to contaminants and contaminated groundwater migration are under control.

External Facilities

 * The Hypervelocity Wind Tunnel 9 is located in Silver Spring, Maryland
 * The National Full-Scale Aerodynamics Complex (NFAC) is located at NASA Ames Research Center, Moffett Field, California. The NFAC was closed by NASA in 2003. In February 2006, AEDC entered into an agreement with NASA to lease the facility for a period of up to 25 years.
