Software Correction

  • Attenuation

    • Use of “Fired” & “Unfired” data

  • Cut-off Frequency

    • Input & Output Cut-off Frequency determined to be 22 Hz for 99%; 9 Hz for 95%.


Results

Results

  • Harmonic Characteristics

    • Fired Rocket

      • f_n = 56 Hz

      • z = 0.02

    • Unfired Rocket

      • f_n = 45 Hz

      • z = 0.02
