HYPERVELOCITY WIND TUNNEL NO. 9 



Naval Surface Weapons Center, White Oak Laboratory 



U.S. Navy 



"Big Science" Descriptor : Hypersonic aerodynamics 



Description of Facility/Instrument : The Hypervelocity Wind Tunnel is 



a unique facility which provides ground simulation of aerodynamics 

 and aerothermal conditions required for the design and performance 

 evaluation of reentry vehicles, decoys, and interceptors at Mach 

 numbers of 10 and lA. It currently simulates reentry flow condi- 

 tions from 40,000 feet to about 200,000 feet which is the critical 

 moderate altitude regime of interest to strategic missile systems 

 and defensive Interceptor systems.
