This 53 second movie clip shows a time lapsed film of Active Aeroelastic Wing (AAW) Wing Loads Test

Active Aeroelastic Wing is a two-phase NASA--Air Force flight research program to investigate the potential of aerodynamically twisting flexible wings to improve maneuverability of high-performance aircraft at transonic and supersonic speeds, with traditional control surfaces such as ailerons and leading-edge flaps used to induce the twist. The program is developing data and structural modeling techniques and tools to help design lighter, more flexible high aspect-ratio wings for future high-performance aircraft, which could translate to more economical operation or greater payload capability.

The program uses a modified F/A-18A Hornet as its testbed aircraft, with wings that were modified to the flexibility of the original pre-production F-18 wing. Other modifications include a new actuator to operate the outboard portion of a divided leading edge flap over a greater range and rate, and a research flight control system to host the aeroelastic wing control laws. The Active Aeroelastic Wing Program is jointly funded and managed by the Air Force Research Laboratory and NASA Dryden Flight Research Center, with Boeing's Phantom Works as prime contractor.
