Responsible Engineers: Summer, Nicole, Servando, Steph, Marcos, Ryan, Cameron, Vaneeza, Vealy

Tentative Schedule:

  • Week 1: Materials & Manufacturing Research and Post-launch Analysis
  • Week 2: Materials & Manufacturing Research and Post-launch Analysis pt. 2 electric boogalo
  • Week 3: Research Review & Intro to Heat Transfer
  • Week 4: Avionics Collaboration/Camera Thermal Testing
  • Week 5: Intro to Aerodynamics
  • Week 6 & on: TBD

Deliverables:

  • Week 1: Review launch footage, notes, etc. and compile all aeroshell-related launch problems. Research into different materials (resin, PLA, aluminum, carbon fiber??) and manufacturing processes (additive manufacturing, machining, composites??) to be used for aeroshells. Try to find information on each material including thermal conductivity, emissivity (for radiation), cost, and any other properties deemed important by you. Additionally, consider paint and other coatings that could enhance the thermal and radiative properties of the aeroshells. Prepare your research in a way that will be easy to "present" to the team on Week 3ish. This could be a spreadsheet, Slides presentation, paragraph with the information. etc. This is due in two weeks (by Week 3).
  • Week 2: Work on above deliverables.
  • Week 3: Determine which methods of heat transfer from lecture apply to the aeroshell problem (you do not need to model the aeroshells accurately or at all to do this, since we technically have not learned the skills to be able to do that well). Keep this at a more conceptual level, although you can do some basic calculations if it helps you. Accordingly, recommend 1 or 2 materials from your list (or do more research if you think you need to) that you believe the aeroshells should be made of. Prepare the information in a way that everyone can understand, much like in Week 1. Be prepared to defend your choice.
  • Week 4 & on: TBD



Things to address:

    • Trapping heat (camera failure)
      • Identify failure point (camera, battery, and/or sd card)
    • Structural integrity (SD card crushed upon impact)
    • Induced drag decreases altitude

Possible solutions:

Heat Issue:

  • Heat sink/Heat fin design to dissipate heat
  • Thin material layer covering aeroshell: Teflon (PTFE) sheet, Aluminum foil 
  • Apply Heat Reflective Paint to outside of aeroshells

Structural Integrity:

  • Triangular infill for 3D print

Drag:

  • Integrate SD card hardware onto avionics bay

More things to look into:

  • How long the rocket was on the launchpad
  • Impact of booster heat on aeroshells
