SHOT II POST-LAUNCH

JUNE 13, 2010


EXPECTED RESULTS:

  • H-bridge temperature increased rapidly during vacuum tests. This mission will test the thermal properties of the H-bridge in low pressure combined with low temperatures (-80 °C).


ACTUAL RESULTS:

Mean ΔT: 4.75 °C


OUTCOME:

  • Partial failure of logging payload

    • Temperature?

    • Loose Connection?

    • Batteries?

  • Data acquired does not match expected results

    • In vacuum chamber, component did not reach a steady-state ΔT after 30 minutes

    • In payload, ΔT established almost instantaneously, at 5 C


ANALYSISAND CONCLUSION:

  • Cause for discrepancy?

    • Different vessel size (small insulated box vs open board)

    • Ambient temperatures vs Box temperature

  • Requires additional testing:

    • Consistent ΔT on SHOT payload, but varying on initial vacuum test

    • Short in actual test magtorquer (not in our simulated one)

    • Likely heatsink h-bridges to Oculus-ASR structure
