Status Update


  • Hati with Wing Set 3
    • MOI and mass properties testing data sent to team
    • GVT data sent to STI
      • Will analyze and validate UMN’s results, then send to VT
    • Aft c.g. tests planned at 23 m/s and 26 m/s to gather open-loop dynamics data
    • Considering testing foreward c.g. for better low speed stability
      • Seems like a low damped phugoid is causing stability issues below 15 m/s
  • CM Soft modeling Hati + FEM 3.3
  • Dave S. analyzing mis-match between models and flight test results for Skoll + WS1
    • Two reasons for different slope of flutter frequency with speed
      • Mode shape
      • Lift distribution
