 NASA 



"Big Science" Descriptor ; Aerodynamics 



Description of Facility/Instrument : This wind tunnel complex Includes a 

 Mach 8 variable density tunnel that can measure heat transfer, 

 pressure, force, and flow visualization data, and a Mach 6 high 

 Reynolds number tunnel that Is capable of fundamental aero- 

 dynamics and fluid dynamics studies over a large Reynolds 

 number Range.

LOW- SPEED WIND TUNNEL COMPLEX 



Ames Research Center 



NASA 



"Big Science" Descriptor ; Aerodynamics 



Description of Facility/ Instrument ; This complex has wind tunnels to 

 test airplane and aerospace craft, including a 40x80 wind tunnel; 

 80x120 wind tunnel; static stand; anechoic chamber; a 7x10 wind 

 tunnel, and a 12-foot pressure tunnel. They are used for testing 

 V/STOL; helicopters; propulsion airframe Integration; engines 

 and nozzles; propulsion/ Nacelle wings in large-scale subsonic 

 testing; static performance and noise; and airframes in tunnel 

 scale.
