  2. Type up list of design requirements
  3. Start researching balloon flight and atmospheric properties

Notes

  • What do you want to get out of the class?
    • How to use and apply solar power
    • What engineering process is
    • How scientists do science in teams
    • How to utilize research resources
    • Learn about environmental affects on circuits
  • Design Process
    • Ensures that the end product is what you want it to be
    • There's a temptation to skip steps, but you probably shouldn't (at least according to class)
    • What's the most important step?
      • Maybe definition of requirements - to know what end product should look like.
      • Maybe knowledge construction - to have a focus on what knowledge is required for project. It's good not to "reinvent wheel" because you don't know what's out there.
      • Maybe situation analysis - to know what's available and what of that you can use.
    • You might be able to skip parts of steps if parts are not relevant to project. For instance, breaking down to time requirements might not be helpful.
    • Time line
      • Stage 1 (2 week)
      • Stage 2 (4-5 weeks)
      • Stage 3 (2-3 weeks)
      • Stage 4 (4-5 weeks)
    • Situation Analysis
      • Four teams - structures, power, imaging, "crazy science"
      • Budget - $400
      • Launch from central Washington (typical)
      • VAST (college) meetings are at 4:30 PM, Mondays, in Engineering Physics 216
      • Launch time is about 2-3 hours
    • Requirements
      • Environmental related (temperature, pressure, wind)
      • Vibration (shaking during descent, 200 mph jet stream)
      • Shock from hitting ground (impact)
      • Background radiation
      • Size (mass [6 lbs], and mass/area for FAA regulations)
    • Resources available for help
