Title : F-18 HARV final flight over Edwards AFB
Caption :
The final flight for the F-18 High Alpha Research Vehicle (HARV) took place at NASA Dryden Flight Research Center, Edwards, California, on May 29, 1996 and was flown by NASA pilot Ed Schneider. The highly modified F-18 airplane flew 383 flights over a nine year period and demonstrated concepts that greatly increase fighter maneuverability. Among concepts proven in the aircraft is the use of paddles to direct jet engine exhaust in cases of extreme altitudes where conventional control surfaces lose effectiveness. Another concept, developed by NASA Langley Research Center, is a deployable wing-like surface installed on the nose of the aircraft for increased right and left (yaw) control on nose-high flight angles.
