AEDC tunnel back online after $33 million upgrade

The AEDC wind tunnel 4T, known for store separation testing as well as conventional sting-mounted force and pressure model testing, is now back online after a $33 million facility upgrade effort. The work was funded by the Test Investment Planning and Programming (TIPP) and the Direct Budget Authority (DBA) programs.

The upgrade to the tunnel extends the range of testing capability for store separation testing to above 1000 psf (up to ~2000 psf), provides the ability for improved operational flexibility and control of the nozzle, and the new data system is now common to the Von Karman Facility tunnels at AEDC with post-processing capabilities both on- and off-line, according to Ozey Young, Air Force program manager and Jon Seely, ATA program manager.
