"Big Science" Descriptor : Supercomputers for computational aerodynamics 



Description of Facility/Instrument ; Plans call for the facility to be 

 centered around two high-speed processors which will be the most 

 advanced cotmnerclally available supercomputers. The first, a 

 Cray 2 supercomputer. Is scheduled for delivery In 1985. The 

 system also will have long-haul telecommunications links to allow 

 access to the NAS by remote users. The system Is being designed 

 so that more advanced hardware can be added as It becomes avail- 

 able In future years. The NAS will assist In simulating the 

 three-dimensional flow of air over aircraft, thus complementing 

 NASA's wind tunnels used In aerodynamic design and testing. The 

 NAS will be available to other users Including government labora- 

 tories, university scientists, and aeronautical Industries. 



Date of Construction ; NAS Is scheduled to be fully operational by 1986. 



Construction Cost : 198A $$ : NASA estimates the cost of the NAS to 

 be approximately $120 million for FY84 to FY88. NASA received 

 $43.5 million for the NAS In FY84 and FY85 and has requested 

 $28.2 million for FY86.
