Team K3 CFinal Team Presentation

• Khin Oo, Kim Gleffe, Carlie Bolin, Katelyn Harder
• AEM 1905 11/16/11

Mission Overview

• Objective 1
• Test the Water Pressure vs. Temperature chart
• We are trying to prove the graph to be factual
• Objective 2
• Test if some sound frequencies are lost as the
  air thins in near space
• We are trying to prove this theory
• Objective 3
• To record the internal and external temperature,
  relative humidity, and pressure
• We are trying to show the relationship between
  temperature, relative humidity, and pressure
  throughout the flight

Programming

• Camera recorded the flight
• Hobo data every 2 seconds
• Advanced sensor zigbee suite data approximately
  every 10 seconds
• Accelerometer every 1 second
• Voice recorder continuous recording

8
Payload Layout
9
Payload Construction

• The interior of the payload and surrounding
  components

10
Payload Pre-flight Testing

• Tests completed
• Payload survival test
• Yank test
• BSE
• Camera
• Pneumatic tubing
• Thermal testing
• Voice recorder
• Siren

11
Payload Survival Test

• After three failed attempts we finally were able
  to get it right. We figured out that we need to
  attach the lid more securely as it would fall off
  during the first three attempts.

12

• BSE Tests

Pneumatic Tubing Tests

• Freezing
• Water in the tube
• No leaks
• All three of the tests were successful

13
Cold Soak Testing

• Camera

Thermal

• The camera was half exposed for the whole flight
  so we tested to be sure it would be warm enough
  for the whole flight while still being half
  exposed

• We tested out the heater along with the inside
  components
• The heater worked great

14
Cold Soak Graphs
15
Yank Test

• Test the security of the innards and the
  structure of the box

16
Tests We Didn't Run

• Video camera with different states of water
• Voice recorder testing

17
Expected Science Results

•  Water experiment
• We tried to show that at a point in the
  atmosphere, the water will go directly from a
  solid to a gas
• Sound experiment
• We tried to show that some frequencies are indeed
  lost as the payload reaches the upper atmosphere

18
Flight Day

• Attaching the camera

• Finishing the payload before takeoff

• Tinting the water for our experiment red

19
Flight Day

• Our payload right before flight

• The inflating of the balloon

20
Recovery

• The Middle Schools payload recovery

• The recovery of the class balloon

21
Flight Day - After Inspection

• It suffered no external or interior damage that
  we could see
• When it was recovered it was still running but
  soon after was turned off or was out of data
  space so didn't record any new data

Conclusions/Lessons Learned

• Summary
• Water experiment
• It changes states but not according to the chart
• Didnt reach perfect points
• Could try
• Different vessels
• Measure water even if some spilled
• Jello or other matter

35
Conclusions/Lessons Learned

• Summary
• Sound experiment
• Couldnt get sound off to analyze
• Tried 2 Windows 7, Vista, Lion
• We got sound
• Could try
• Different recorder
• Different sound/range

36
Words of Wisdom

• Think of everything before you start making
  holes.
• Time is your frenemy.
• Get things done early!
• Make sure everything is functioning before you
  seal it.
• The more tape, the better!
• You know you dont get to eat until you find the
  balloon.
• Get friendly with Excel.
• Get a wireless mousedont use trackpad to make
  graphs.
