Closing Thoughts
CFD e/ists to ena!le new solutions to pro!lems$ reduce airplanedevelopment cost$ and reduce time to mar-et
CFD can allow you to safely e/plore areas of the flight regime
without putting a pilot at ris-
CFD can allow you to analy.e conditions for which physical
simulation is either very e/pensive or not possi!le$ such ashypersonic propulsion systems and full flight #eynolds num!er
testing
Accuracy$ ro!ustness and timeliness are the -eys to acceptance
and use in an industrial environment
Impediments applications that do not scale well &to 14445s of
processors with sufficient memory' this is scienceK resources to
run 1444s of flight conditions on 1445s of processors this is the
!usiness of engineering
