Design and Simulation of Aerospace 

 Vehicles 



Airflow Is simulated over and past the wing of a high performance aircraft that Is using vectored thrust while 

 descending to a few feet above the ground (in ground effect). 



Improved design and simulation of advanced 

 aerospace vehicles is a primary goal of the 

 NASA HPCC Program. Massively parallel pro- 

 cessing and related high performance computing 

 technologies are enabling new simulation and 

 optimization methodologies for flight vehicle 

 design. These methodologies combine multiple 

 physical disciplines and integrate vehicle com- 

 ponents such as the airframe, propulsion sys- 

 tems, and controls. Improved aircraft design 

 resulting from high performance computing 



promises to give the U.S. aerospace industry a 

 critical competitive edge. Early and continuous 

 coordination between NASA research centers, 

 other Federal agencies, academia and industry is 

 crucial to the success of this endeavor. 



Scientists at NASA's Ames Research Center 

 have developed computer simulations of air flow 

 past a delta wing at takeoff and landing that will 

 help design more efficient and cost-effective air- 

 craft. By porting a single discipline computa-
