What is a Hyperloop?


Proposed by Elon Musk, the founder of Tesla and SpaceX



New form of transportation that will consist of a pod traveling in a
low pressured tube on a frictionless surface at speeds near Mach 1.

Purpose
The mission of team Hyperlynx is to design and manufacture a Hyperloop pod
demonstrating the safety, stability and feasibility of the Hyperloop system.



Building a half size pod
14 feet long
 4 feet wide




The pod will be compete in a
proof of concept competition at
SpaceX headquarters in June
2016
Over 200 teams
 1 mile long straight test track
 5 feet diameter tube

compressor
Primary function is to decrease
mass flow rate around the pod to
avoid choked flow
• Also provides compressed air
to the air bearings
Advantages
• Efficiencies up to 90%
• Capable of high mass flow
rates
• Lightweight
