1/7 PROGRESS

TASKS AS FOUND AT BEGINNING OF IAP

Drag test

    • index steel disc (challenging since it doesn't fit in the indexer)
    • make 1/4-20 threads on aluminum tube into through holes for grub screws
    • snag grub screws
    • weld steel disc to steel plate
    • fit check entire stand
    • fit load application sandwich with clevis on instron
    • verify test load derivation and analysis
    • write test procedures
    • manage instrumentation and documentation of test
    • run test

Moment test

    • fix base jig holes (10" apart now, need to be 11" apart)
    • confirm fit on instron
    • work with pierce to coordinate 3 point bend fixture use
    • verify test load derivation and analysis
    • write test procedures
    • manage instrumentation and documentation of test
    • run test

ACCOMPLISHMENTS

  • made 1/4-20 threads on aluminum tube into through holes for grub screws
  • snagged grub screws
  • preliminary fit check of moment test hardware
  • fixed base jig holes with waterjet (thanks Todd!)
  • found load application sandwich in the Deep
  • reached out to Pierce for help with 3 pt bend fixture and clevis fitting
  • reached out to Seth for welding help since Charlie is gone
  • came up with steel disc indexing plan with Todd

RISKS/MITIGATIONS

  • worried that 3 point bend fixture won't work with the whole setup (sort of worrying, this could really set us back)
    • will continue to chase down Pierce
    • bars might have to be elongated
    • worst case scenario we may be able to sandwich with a steel plate and compression bar
  • worried that load application sandwich + clevis won't work with the whole setup
    • will continue to chase down Pierce and make necessary modifications
  • a little rusty on the loads derivation and analysis
    • will set aside a few hours to go over this today

PLAN/MILESTONES

  • 1/8
    • bore and index steel disc with Todd
    • weld with Seth if I can find him
    • meet with Pierce if I can find him
    • work on documentation and test procedures
    • GOAL (unless blockers come up): finish and fit check all hardware
  • 1/9-1/10
    • update documentation 
    • perform initial proof testing with limited instrumentation
  • 1/10-1/12
    • shannon is in NYC visiting a friend
  • 1/13+
    • refine testing and really nail it all down
