Problem

Problem Statement

Build a lightweight and aerodynamically efficient Aerobody

Goals Aerodynamic efficiency will lead to reduced power requirements, this allows us to travel further with the same amount of power. 
Constraints Regulations 

Top surface area of 5m^2 to accomodate array (If curved, then only in 1 plane)

Max dimensions (L x W x H): 5.0m x 2.2m x 1.6m

Criteria 

Coefficient of drag (Cd) < 0.15

Frontal area (A) < 1.5 m2 

Large enough to accommodate 4 people

Requirements

Minimize molds

Minimize cost

Highly durable

Reference materials

 Concept sketches complete, working towards converging to single final sketchDocumented at the Conceptual Design Page

Final aesthetic locked down

  • Blended hood to windshield angle
  • Large catamaran
  • Cambered airfoil design for underbody
  • Body comes down to cover rear wheels
  • Documented at the Conceptual Design page
Rough model in CAD
  • Rough geometry modeled in CAD
  • Minimum array space, length, width, and height considered
  • Wheelbase and track roughly defined
  • Need to add space for front wheel sweep and suspension

Iteration 1
  • Added space for front wheel sweep and suspension
  • Beginning of parametric model
