DescriptionHyperloop represents the future of high speed transit. This is the first endeavor to invent a transportation system that is safer, cheaper, faster and more energy efficient than cars, planes, boats and trains. We have been working diligently to design a half-scale pod for the the SpaceX Hyperloop Competition. SpaceX awarded HyperXite with a Pod Technical Excellence Award, ranking the pod 5th best pod design in the world, 1st in air based levitation, and 1st in California.

ResponsibilitiesLead Compressed Air Systems Engineer- To design a high pressure air system that will provide constant and correct air properties for levitation, suspension, and braking.Lead Vacuum Engineer- Design a vacuum chamber to test all instrumentation and materials for vacuum compatibility.

Compressed Air System


DescriptionThe purpose of the Compressed Air System is to pneumatically actuate the suspension and magnetic braking systems, while delivering a high flow of air to the levitation system. The system begins with two 3,500 psi composite overwrapped pressure vessels (COPV) with two pressure regulators in series to deliver 80 psi to the system. There are ten pressure safety valves to prevent overpressure in the system. A combination of normally open and normally closed 24VDC solenoid valves direct the flow to the appropriate systems. An electronic pressure regulator provides 0.1 psi accuracy to actuate the magnetic braking system. There are eight pressure transducers that will output pressure signals to the programmable logic controller. All together, the system is one fault tolerant to provide redundancy for safety.

Fluids Testing


Thermal Testing:Due to the Joule-Thomson Effect, as air leaves the COPV it experiences a temperature drop and becomes very cold (approximately -3 Celsius). We needed to test the lower limits of the temperature change so that appropriate instrumentation could be selected. We used a thermocouple, flow controller, and a pressure regulator to simulate operating conditions.

Flow Rate and Pressure Testing:Our levitation system mimics the design of a hovercraft, which operates under high flow rates. The necessity for high flow rates drove us to test multiple valves and regulators for optimization. The chart on the left describes the output flow rate of the electronic pressure regulator as a function of pressure. We used pressure regulators, valves, and pressure transducers to simulate operating conditions. These tests were crucial to validating the success of our compressed air system.

Vacuum Compatibility Testing


Vacuum Compatibility Testing is necessary to verify our instrumentation works correctly in vacuum environments. I designed electrical and air feedthroughs to allow us to test inside a vacuum chamber. I tested solenoid valves, electronic pressure regulators, and pressure transducers for long durations under vacuum to simulate the pod in the vacuum tube. Thermal properties were monitored by a temperature gun.

I partnered with the American Vacuum Society to host an all-day vacuum course for the team with a focus on Hyperloop applications. We were able to get insight into the aerospace industry and what considerations have to be made for selecting lubricants, electrical devices, and materials.
