Employees get a closer look at unique AEDC tunnels
                Arnold Engineering Development Complex (AEDC) test engineer, Shannon Tibbals (right) and AEDC outside machinist, Greg Crabtree, get an up-close look at a nozzle in the von Karman’ Gas Dynamics Facility (VKF). VKF includes Tunnels A, B and C and are unique assets in the United States because they are continuous flow with the ability to sustain maximum speed for several days. Improved performance, productivity and reduced energy consumption are expected as part of a recent upgrade.
