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 (C_d) < 0.15 Frontal area (A) < 1.5 m² Large enough to accommodate 4 people
Requirements	Minimize molds Minimize cost Highly durable
