Status Update

  • Annual report in work

mAEWing1

  • UMN
    • Sköll with WS1 flight 03 completed on July 2, good parameter estimation dataset captured at 20 m/s
    • Sköll with WS1 flight 04 completed on July 9, parameter estimation dataset captured at 30 m/s; significant flexible dynamics observed
  • STI
    • ROM completed
    • Can approximate model at different speeds
  • Dave S.
    • Model matches with STI
    • Waiting for FEM from VT, will redo model and analysis following FEM update
  • VT
    • Point mass model of Sköll
    • Tuning based on mass properties testing completed at UMN
    • C.G. error still significant
  • CM Soft
    • Finding critical flutter points
    • Inviscid flow with two different boundary conditions:
      • Free to move
      • Clamped
    • Using a nonlinear aero and full FEM, STI is using linear aero and reduced structural model
