Voltage Probes

• Same as last run except 8 channels have AB
  monitoring
• Allows monitoring of out-of-plane loading
• Web page developed to archive probe vs. channel
  assignments (instead of reliance on notebook
  records)

Fiber Optic Temperature, Strain, and Displacement

• Flags (inner, outer/top, bottom)
• 4 flags x 3 strain/flag 12 strain
• 4 flags x 1 temp/flag 4 temp
• Hub and Flag twist angle (top, bottom)
• 2 displacement
• Flag end ?Z ?? motion (top, bottom)
• 4 displacement
• Hub (top only)
• 1 displacement

Benchmarking Procedure

• Fit Structural Coefficients to Measurements
• Identify Worst Case Joint
• Re-Run Engineering models
• Re-Assess 6kG Performance
