Videogrammetric Model Deformation (VMD)

Highly accurate, real-time measurement of wind tunnel model deformation (wing twist, wing bending, sting bending) with strong applicability to aeroelasticity testing. Recently adapted to obtain in-flight aeroelastic wing deformation measurements on an F-18E/F.

Applicability:

• Obtain static and dynamic aeroelastic measurements in wind tunnels
• Useful for a number of tests at NASA facilities
  • National Transonic Facility
  • 16-Ft Transonic Dynamics Tunnel
  • Transonic Dynamics Tunnel
  • Unitary Plan Wind Tunnel
  • Ames 12-Ft Pressure Tunnel
