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
