  1. SpaceCenteredReading of EarAudibilityMeasurements Josh Yeaton Kevin Dinkel Chris Kopacz Conrad Schmidt Chris Warren Dillon Thorse PROJECT SCREAM PROPOSAL 09.23.08

  2. Mission Statement • Ascend to an altitude between 25,000 – 30,000 meters to better understand how sound behaves in near space conditions. • It is a known fact that sound cannot be heard in the vacuum of space because sound waves require a transport medium. • We hypothesize that as our BalloonSat nears the silence of space, sound amplitude will decrease as a function of altitude. • We theorize that a 261.33 Hertz middle C, played at a constant decibel level on ground, will decrease in amplitude as altitude increases and air pressure decreases. • Project SCREAM shall also produce photographic images of the horizon of Earth using the digital camera provided.

  3. Design Concept • DIM: 30cm x 14cm x 14cm • Sound Chamber • Component Placement

  4. Weight Budget

  5. Price Budget

  6. Impact: Stair Test Drop Test Whip Test Systems: Components Test Dry Ice Test Testing

  7. Team Safety • Awareness. • Communication Techniques • Safety Glasses • Gloves • Structural Test Safety (bystanders and team members) • Vigilance Around Sharp Objects and Electric Currents

  8. General Proposal Requirements • All necessary systems such as the HOBO will be on board to take fundamental data readings. • The satellite will stay above zero degrees Celsius because of the on board heater and insulation. • Primary experiment is separate from the on board camera and HOBO data loggings. • Experiment will consist of a sound chamber, a sound emitter, and a sound receiver. • Satellite will be structurally sound so that all the experiments will be performed, logged, and retrieved.

  9. Launch Program • Team SCREAM will be ready to leave with our satellite at 0500 on November 27. • Team SCREAM will arrive at Windsor, Colorado at 0730 ready to launch. • 1.5 hours before the flight team SCREAM will do a systems and structures inspection. • Team SCREAM will then secure the satellite to the balloon by running the rope through the satellite. • A representative from Team SCREAM will hold the satellite in a line with the other satellites and release it when appropriate. • Team SCREAM will then locate the satellite. • Once team SCREAM has found the satellite they will turn off the systems and inspect it to see if there is any structural damage. • Team SCREAM will then secure the satellite in preparation to collect data. • Team SCREAM will eat a well-deserved lunch after a long day of launching and chasing.

  11. Team Organization • Joshua Yeaton: Team Leader/Microphone and Speaker Configuration • Kevin Dinkel: Budget Organization/Structures • Dillon Thorse: Structures/Camera • Conrad Schmidt: Soldering/Electrical • Chris Kopacz: Structures/Camera • Chris Warren: Microphone/Speaker Configuration

  12. Team Organization (Cont.) • As all members of the team are aerospace engineering majors with little experience in their respective areas, these designations are somewhat flexible. • If anyone needs help with a specific assigned part of the satellite, the rest of the team will assist as needed.

  15. Team SCREAM’s Screamers • Having an audible/recordable sound • Lots of electronics, one heater enough? • Satellite weight, lots of bulky items • Testing, components are tightly packed, no room for movement/error • Recording Altitude?
