Best Practices in Wind Tunnel Testing


Best Practices in Wind Tunnel Testing provides an overview of important concepts that are used in many wind tunnel test projects. The course is based largely on AIAA standards documents which focus on ground testing concepts. In particular, the course will address project management aspects of executing a testing project, the use and calibration of strain gage balances, the use of measurement uncertainty in ground testing, and the calibration of wind tunnels.

Key Topics:

  • Wind Tunnel Test Processes
  • Measurement uncertainty analysis for wind tunnel testing
  • Internal strain gage balances for wind tunnel testing
  • Aero-thermal calibration of wind tunnels

Who Should Attend:

The course is designed for engineers who are involved with ground testing, particularly wind tunnel testing. The course will be beneficial to all levels of ground test engineers; it could be a primer for engineers new to testing but also will be of value to senior engineers as it will include lessons learned that can be directly applied by test project leaders.
