2. Description
Hyperloop 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.
Responsibilities
Lead 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.

3. Compressed Air System
Project Link: HyperXite.com
Description
The 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.

5. 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.

6. 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.
