Criteria

  • Size: A smaller, thinner AEV will prove better for traveling through the air and will help reduce friction witht the track.
  • Cost: The cost of the materials for building the AEV (specifically the 3-D printed part) must be as minimal as possible.
  • Aerodynamics: The AEV’s ability to disperse the air it glides through while losing minimal speed.
  • Weight Distribution: The balance of the AEV being at equilibrium to avoid unnecessary friction.

Design Pros and Cons

  • Noah’s Design:
    • Pros- Well-built, cost effective, and thin.
    • Cons- Not very aerodynamic
  • Andrew’s Design:
    • Pros- Effective shape and weight distribution
    • Cons- Basic and not aerodynamic
  • Ben’s Design:
    • Pros- Small and cost effective
    • Cons- Performance likely to be ineffective
  • Anil’s Design:
    • Pros- Aerodynamic and weight distributed well
    • Cons- Costly and aero part is not guaranteed
  • Combo Design
    • Pros- Aerodynamic, weight distributed well, printed part will not be costly, and well built
    • Cons- Printed part not guaranteed

Final AEV Designs

  • Noah’s design and Combo design were decided by the group to be carried forward
