Chris Carr, an AEDC Instrumentation, Data and Controls engineer, demonstrates how the Cross-Domain Solution, or CDS, works Feb. 12, 2020, at Arnold Air Force Base, Tenn. The CDS interface was researched as a solution to allow plant operations systems outside of the plant control room to remain unclassified during classified test programs. As part of an AEDC Innovation Grant project, Carr and several AEDC team members worked together to determine whether plant control parameters could be normalized with the addition of a CDS.
