Datacor xStream | North Wind Test LLC Air Hammer Validation

 North Wind Test LLC had decades of confidence in NASA's GTRAN code. Before making the switch to a modern platform, they ran a rigorous side-by-side validation across a 0 to 2 second transient. xStream matched GTRAN's pressure fluctuation magnitudes and mass flow behavior within approximately 5% -- with nearly exact timing alignment on every spike and trough. 

• Pressure and mass flow results matched GTRAN within approximately 5%
• Pressure spike timing aligned nearly exactly across the full transient window
• Revealed unique tank-to-tank ringing behavior not previously captured
• Enabled full transition to a modern, maintainable toolset
