ARNOLD AIR FORCE BASE, Tenn. (AP) – The Arnold Engineering Development Center in Tennessee has upgraded its Engine Data Acquisition and Processing System in what facility officials call a milestone.

It was a $2 million, six-year project to develop new engine data sources for temperature and voltage measurements for turbine test cells.

Officials at the center in Tullahoma said the new data sources are more robust and accurate. No pre-test calibrations are needed, reducing the work load of the test crew. Additionally, the modular design of the new systems reduces energy cost.

The center, operated by the U.S. Air Force, is a complex of wind tunnels and other specialized units.
