High Quality Data
Data Repeatability - Primary measure of quality
- Single piece high-capacity balances improve temperature stability
- New cooling towers improve tunnel temperature control
- Test methods to achieve run speed and repeatability requirements
- Calibration models, flow surveys, and static pipe measurement conducted
- at regular intervals ensure consistency (Latest 2020)
Data Usability - Applicability to full-scale Testing
- 8’x8’ test section allows larger-scale models that better represent actual aircraft
- Mach Number of 0.2 to 1.30 captures critical transonic speeds
- A broad range of altitudes and Reynolds numbers with stagnation pressure of 0.25 to 3.25 atm.
- Corrections for tunnel-induced effects
- Supplemental flow visualization provides insight
