10- by 10-Foot Supersonic Wind Tunnel 10- by 10-Foot Supersonic Wind Tunnel
The 10- by 10-Foot Supersonic Wind Tunnel at GRC is a dual-cycle wind tunnel that operates either as a closed-loop (aerodynamic cycle) or open-loop (propulsion cycle) facility, reaching test section speeds of Mach 2.0 to 3.5. The tunnel can test supersonic aerodynamic and propulsion components such as inlets and nozzles, integrated propulsion systems, full-scale jet and rocket engines, and launch vehicle concepts. It provides continuous operation across the speed and altitude ranges, offering users greater flexibility and productivity during testing. The 10- by 10-foot tunnel has made contributions to the space shuttle, the High-Speed Civil Transport, the National AeroSpace Plane, the Joint Strike Fighter, and to the advancement of fundamental supersonic propulsion technology.

9- by 7-Foot Supersonic Wind Tunnel 9- by 7-Foot Supersonic Wind Tunnel
The 9- by 7-Foot Supersonic Wind Tunnel at ARC, which shares the drive line with the 11-foot tunnel, has also been used extensively in the development of virtually every domestic fixed wing airframe that operates in supersonic regimes and has played a critical role in space exploration. This facility has provided ascent and reentry aerodynamic data for every NASA-designed, manned space-flight program, including the space shuttle and NASA's Constellation Program. The facility is also slated to test parachutes for future unmanned probes to Mars.

4-Foot Supersonic Unitary Plan Wind Tunnel 4-Foot Supersonic Unitary Plan Wind Tunnel
The Unitary Plan Wind Tunnel (UPWT), one of LaRC's core facilities, is a versatile, heavily utilized wind tunnel capable of supporting basic fluid dynamics research as well as applied aerodynamic research. This facility, which is utilized by NASA, DOD, and industry customers, contributes significantly to the development, assessment, and optimization of advanced aerospace vehicle concepts. The facility is utilized in support of major research programs such as Hyper-X (X43), X-43C, JSF, DARPA QSP, CEV, and Crew Launch Vehicle (CLV). UPWT contributions include both database development during the configuration design screening process, a first phase in configuration selection for a particular mission, and benchmarking the aerodynamic and aerothermodynamic configuration information for the selected mission concept. The UPWT, which is the only large operational supersonic tunnel at LaRC, is critical to LaRC's and NASA's mission.

8- by 6-Foot Supersonic Wind Tunnel 8- by 6-Foot Supersonic Wind Tunnel
The 8- by 6-Foot Supersonic Wind Tunnel at GRC provides researchers the opportunity to test aerodynamic and propulsion models at subsonic, transonic, and supersonic speeds from Mach 0.25 to 2.0. Specialized support systems, a variety of research test hardware, and a calibrated test section support the development of aircraft, launch vehicles, and their components. Traditional tests include vehicle force and moment, inlet airframe integration, sonic boom mitigation, and inlet performance. The 8- by 6-foot tunnel has supported major programs such as the Advanced Turboprop, the National Aerospace Plane, the Advanced Tactical Fighter, the Joint Strike Fighter, the High-Speed Civil Transport, and the space shuttle.
