Team Dionysus Critical Design Review

1. Team DionysusCritical Design Review Alijah Smith, Chris Koncilja, Elise Kowalski, Josh Tiras, Mike Beach, Becca Seigel 10/06/09

2. Organization Chart

3. Mission Overview • Mission Overview • Objective: Use infrared sensor and an ultraviolet sensor to determine the flux of infrared and ultraviolet light throughout the troposphere and lower stratosphere • We expect to prove that UV and IR light intensity increase with altitude • Hypothesis: UV and IR light intensity increase with altitude • Understanding penetration of light can help protect people from radiation from the sun. Large amounts of radiation can damage people’s skin and have other negative effects on other life on earth.

4. Requirements Flow Down

5. Design • Use sensors attached to top of cube and convert the data received from amps to volts. • Parts • Ultraviolet Sensor – ordered • Infrared Sensor – ordered • Expected to arrive Oct. 6th, 2009

11. Test Plan • Payload Testing: Whip, Drop, Cold, Stair Tests • Sensor Testing: AVR test, Calibration, Blacklight, Heat lamp • Schedule • 11th – Team meeting: Construction • 12th – Team meeting: Construction, empty shell/mass sim. test • 13th – Team meeting: Construction, sensor tests • 18th – Team meeting: Construction, payload tests • 20th – Team meeting: construction, sensors and structure tests • 25th – Team meeting: All Testing Complete • 27th – Pre Launch Inspection • 29th – Mission Simulation

12. Expected Results • We expect to see an increase in radiation as altitude increases. • UV: 0 - 0.6 Watts per m^2 per nanometer • IR Ground: 0.5-1 Watts per m^2 per nanometer • IR at altitude: 1-1.5 Watts per m^2 per nanometer

15. Biggest Worries • Sensor Accuracy/Error • Severity of Impact • Parachute Failing • Finding proper resistor for amps to volts conversion
