Lehigh Hyperloop

Our mission

Design and build a prototype, or “pod,” that will travel up to 180 m/s (400 mph), revolutionizing the transportation industry.

We are a dedicated group of undergraduate students who firmly believe that Hyperloop will play a grand role in the ground transportation around the globe.

Levitation Motor

• Peak Power: 30kW per motor • Note: Motors won’t be running at full power

• Units: 4• Motor Weight: 11kg• Tesla Battery Units Needed for 15 Minute Hover Test: 1• System Weight: 80kg (not including batteries)

WheelsetThe brackets on the wheel assembly will attach directly to the chassis

PropulsionCold Air Propulsion

Stability

• Air bearings placed on both sides of I beam, front and back, for balance

• Air bearings could self-regulate. When over the self-regulation threshold, the flow control valves assist in pressure change to maintain balance

• Four air bearings using 21psi and 18.4cfm from a pre-loaded tank

Overall Lateral Control Design

Braking (Eddy Current and Emergency)

Braking (Friction)Wilwood PolyMatrix-H brake pads, consistent COF with respect to temperature changes

Life-SupportPurpose: To sustain a closed system within the pressurized pod that maintains a stable and comfortable breathing environment with ample supply for extended journeys.

Life Support Chamber Components

• 4 Tesla Model-S batteries, each with 24 V, 250 Ah• Back up: 2 Tesla Rav-4 batteries, each with 29 V, 100 Ah• 14-L air tank with 3500 psi MAWP, 2000 psi MEOP• 12-L Liquid Nitrogen Tank with emergency leak valves

Energy

Safety Features Summary

• Hardware and software redundancy ensure braking to not engage during the acceleration phase

• 25% Power backup can bring the pod to emergency stop• E-Glass sandwich composite hull protect internal components in

case of rapid pressurization

Mechanical Switch

Attached

• Eddy current brake can function as passive gliding and lateral control system

• Reducing regulator system commands prevent single point of failures issue

• Fixed wheels allow the pod to be moved if power loss• Emergency stop command connects mission control with the on-

board server

Safety Features Summary

Hazardous MaterialsLiquid nitrogen and inert heating liquid are kept in a separate temperature controlled housing and high-pressure industrial gas tanks which can endure large pressure and external impacts. The operation also contains redundancy system that completely separate the liquid from mixing chamber that feed into the nozzle. Upon vaporized, liquid nitrogen are non-reactive to any chemical or electrical sparks.

Tesla™ Lithium Ion Battery has various safety features such as fuses on each cell to prevent hazards and specific packing that prevents catastrophic failures.
