Operating Location White Oak, Md.
Hypervelocity Wind Tunnel 9, and AEDC site located at White Oak near Silver Spring, Md., provides aerodynamic simulation critical to hypersonic system development and hypersonic vehicle technologies. The facility supports testing for Air Force, Navy, Army, Missile Defense Agency, and NASA programs, as well as advanced hypersonic technologies such as wave-rider-type vehicles, scramjets and transatmospheric space planes. Tunnel 9 is the primary high Mach number and high Reynolds number facility for hypersonic ground testing and the validation of computational simulations for the Air Force and Department of Defense. Noteworthy advantages over other facilities include a unique storage heater with pressures up to 1,900 atmospheres and temperatures up to 3,650 degrees Rankine. Axisymmetric contoured nozzles for Mach 7, 8, 10 and 14 operation are also available.

Operating Location Moffett Field, Calif.
The National Full-Scale Aerodynamics Complex wind tunnel facility located at the Ames Research Center in Moffett Field, Calif., is operated by the U.S. Air Force's Arnold Engineering Development Center. NFAC is a unique facility primarily used for determining aerodynamic characteristics of large-scale and full-scale rotorcraft and powered-lift V/STOL aircraft, as well as testing of wind turbines, parachutes, trucks, and other non-traditional types of testing. The facility is composed of two large test sections and a common, six-fan drive system. The 40-by-80 foot wind tunnel circuit is capable of providing test velocities up to 300 knots. The 80-by-120 foot test section is the world's largest wind tunnel and is capable of testing a full size Boeing 737 at velocities up to 100 knots.

Operating Location at Eglin, AFB
The McKinley Climatic Laboratory, located at Eglin Air Force Base, Florida, has chambers where any climatic environment in the world can be simulated. The capabilities available at the Climatic Laboratory help engineers ensure maximum reliability and operational capability of complex systems as global operational theaters continue to impose harsh environments. Tests at the facility for the Department of Defense, other government agencies and private industry have included items such as large aircraft, tanks, missile launchers, shelters, engines, automobiles and tire manufacturers.
The Climatic Laboratory has five testing chambers which include the Main Chamber; the Equipment Test Chamber; the Sun, Wind, Rain and Dust Chamber; the Salt Fog Chamber; and the Altitude Chamber.
The Main Chamber (MC) is the largest environmental chamber in the world. At approximately 252 feet wide, 260 feet deep and 70 feet high, tests have consisted of large items and systems for aircraft such as the B-2 Bomber and the C-5 Galaxy. The temperatures achieved in the chamber range between -65 degrees Fahrenheit to 165 degrees Fahrenheit with a simulation of all climatic conditions including heat, snow, rain, wind, sand and dust.
The Equipment Test Chamber is 130 feet long, 30 feet wide and 25 feet high. Although it is smaller, it has the same capabilities of the MC. Tests usually consist of jet engines, small vehicles and turbine-driven ground power units.
The Sun, Wind, Rain and Dust Chamber produces ambient or hot test conditions. Wind-blown rain at rates up to 25 inches per hour and heavy sand and dust storms can also be created in this chamber.
Because of the corrosive properties of salt fog test conditions, the Salt Fog Chamber was designed to provide an ambient test chamber that is away from other test chambers. The chamber has two steam-fed heat exchangers that create the temperature to perform the salt fog test.
The chamber is approximately 55 feet long, 16 feet wide and 16 feet high. The chamber doesn’t have refrigeration capability.
The Altitude Chamber can create pressure altitudes as high as 80,000 feet with a temperature capability of -80 degrees Fahrenheit to 140 degrees Fahrenheit. The chamber measures 13 by 9 feet and 6 feet high.
