Combustion Research and Flow Technology, better known as CRAFT Tech, says it likes to swim in data.

Not just any data, of course. CRAFT Tech immerses itself in terabyte-sized datasets used to simulate complex fluid dynamic and combustive problems. To swim in these waters requires large-scale, parallel architecture computers running specialized CFD codes and the most advanced visualization software.

A recently completed project called HiFAST (High Frequency Acoustic Suppression Technology) showcased CRAFT Tech’s ability to take full advantage of CFD visualizations at every phase of weapons system development. The project, conducted for the Air Force Research Laboratory’s Air Vehicles Directorate (AFRL/VAAI), culminated in a successful flight test of a device that controls internal weapons bay airflow and acoustics.
