In this 2006 photo the installation of new stainless steel ducting and valves with associated hardware is underway from ETF C-Airside Plant to the J/T/SL test cells as part of the Propulsion Consolidation and Streamlining Program. The PC&S Program Phase V, completed in 2007, enabled AEDC to shut down the 1950s-era ETF B-Airside Plant and provide the initial capability for concurrent turbine engine sea level and altitude testing.
