 To test the AAW theory, NASA and the USAF agreed to fund development of a single demonstrator, based on the F/A-18.Work started by taking an existing F/A-18 airframe modified with a preproduction wing, and added an outboard leading edge flap drive system and an updated flight control computer.Active aeroelastic wing control laws were developed to flex the wing, and flight instrumentation was used to accurately measure the aeroelastic performance of the wing planform.
