Langley Research Center 



NASA 



"Big Science" Descriptor ; Aerodynamics 



Description of Facility/Instrument : This tunnel Is capable of large- 

 scale temperature, pressure, and Mach number simulation for 

 structures and propulsion. This facility Is also used for evalu- 

 ating hypersonic and space structures, Ram/Scram jets and 

 missiles, and aero/thermodynamlcs. (Use: 10 percent military 

 and 90 percent NASA unique.)
