Title : F-18 HARV smoke and tuft vortex flow visualization along leading edge extension

Caption :

Flow visualization smoke marks vortex flows along the leading edge extension on an F/A-18 flown by NASA's Dryden Flight Research Center, Edwards, California, in its High Alpha Research Vehicle (HARV) program. The aircraft is at a high angle of attack in this photo. The aircraft was modified with a thrust vectoring system to further investigate high angle of attack flying. The program was conducted jointly with NASA's Langley Research Center.
