Team K^3 + CFinal Team Presentation

Khin Oo, Kim Gleffe, Carlie Bolin, Katelyn HarderAEM 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

Parts List

Design Overview – Budget and Mass

Block DiagramHOBO Data Logger

(Monitors "interior health" of payload)

HOBO Temperature Probes(Will collect temperature data and send to HOBO data

logger)

Flip Ultra Video Camera(Records visual data of water experiment)

Zigbee(Transmit advanced sensor suite data back to the

ground)

Advanced Sensor Suite(Probes collect temperature, relative humidity, and

pressure data; sends data to zigbee)

3 Pack 9 Volt Battery(Provides power for heater)

Heater Circuit(Heats the inside of the payload to prevent freezing of

components)

Accelerometer(Collects x, y, and z orientation data)

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

Payload Layout

Payload Construction

• The interior of the payload and surrounding components

Payload Pre-flight Testing

•Tests completed▫Payload survival

test▫Yank test▫BSE ▫Camera▫Pneumatic tubing▫Thermal testing▫Voice recorder▫Siren

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.

BSE TestsPneumatic Tubing Tests

•Freezing•Water in the tube•No leaks

All three of the tests were successful

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

Cold Soak Graphs

Yank Test

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

Tests We Didn't Run

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

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

Flight Day

• Finishing the payload before takeoff

• Tinting the water for our experiment red

• Attaching the camera

Flight Day

• The inflating of the balloon

• Our payload right before flight

Recovery

• The Middle Schools payload recovery

• The recovery of the class balloon

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• Didn’t reach perfect points

– Could try• Different vessels• Measure water even if some spilled• Jello or other matter

Conclusions/Lessons Learned• Summary

– Sound experiment:• Couldn’t get sound off to analyze• Tried 2 Windows 7, Vista, Lion• We got sound

– Could try• Different recorder• Different sound/range

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 don’t get to eat until you find the

balloon.•Get friendly with Excel.•Get a wireless mouse…don’t use trackpad to make

graphs.

Thanks!
