OVERVIEW
Team Inworks’ Hyperloop Pod development will focus on the computer and communication systems as well as a modular payload system.
To test these concepts, we will enter a micropod into the wheeled vehicle category at Competition Weekend.

PROPULSIONWe will utilize a cold gas thruster system
consisting of a compressed air canister pressurized to 4500 PSI.
A power driven valve controlled by the primary pod control system will control the system. The air will be expelled through a thrust nozzle. This
valve can be shut remotely via the “Pod Stop” command.

POD DIRECTION
This system is primarily intended to support our prototype design by
compensating for the speed loss caused by the wheels and does not
represent our proposal for a full-scale hyperloop propulsion system.
PROPULSION / STABILIZATION
The pod will be stabilized by horizontally and vertically mounted wheels which engage the center rail.
The horizontally mounted wheels will feature a low speed electric motor system and will interface with the braking system.

NAVIGATIONThe Primary Pod Control
System will control the navigation system. A triple-axis
digital output gyroscope with built-in accelerometer will
monitor velocity, pitch, yaw, and roll.
Self-contained, full-spectrum photoelectric sensors mounted
on the front of the pod will establish location by detecting
change in appearance of the linear distance markers.
7
BRAKINGThe pod will employ a disc braking system. These brakes will be electrically actuated via the Primary Pod Control System.
We are exploring adapting an ABS system from motorcycle technology.
This system can be remotely activated via the “Pod Stop” command.

LEVITATION
The current design will not feature levitation.
Depending on availability of funding following Design Weekend, we will conduct a cost benefit analysis and research air bearing and magnetic levitation technologies.

COMPUTER SYSTEM OVERVIEW
The embedded computer system will continuously assess, manage, and adjust the status of the pod and provide external communications capabilities.

POD CONTROL SYSTEMThe Primary and Secondary Control System will provide logical operations to the hyperloop pod.
The Primary will act as the main driver for system controls while the Secondary will serve as a redundancy to the Primary.

REAL TIME OPERATING SYSTEM
All embedded system architecture for the unmanned pod will be run through a Real Time Operating System (RTOS) for unified computing and analysis.
The inherently faster processing capability that an RTOS provides allows rapid detection of emergency situations by reducing latency.

RTOS Overview
MODULAR PAYLOAD
The middle section of our pod will accommodate a modular payload system.
A modular payload system in a full scale hyperloop design will significantly reduce the cost of construction and operation of the pods, support multiple configurations, control weight distribution, and allow rapid turnaround of the pods at the station.Modular Payload Concept
14
MODULAR PAYLOADThe modules would be designed to support multiple configurations and a variety of user types.
15
Single Person / ADA Sleeper Two Person Group / Family / Economy Cargo / Luggage / Freight
Controlling the arrangement of the modules will allow for optimization of weight distribution according to the loads, improving the pod’s overall stability and performance.
MODULAR PAYLOADA modular payload system would drastically improve
turnaround time once a hyperloop pod arrives at the station.
This would reduce the number of pods required in circulation in order to maintain the operating schedule
of the route, thereby reducing overall cost.
16
These modules would also optimize maintenance and upkeep of the system by allowing time for the modules to be maintained between
use in the system while keeping all pods in circulation.
MODULAR PAYLOADThe sleeper modules could be used within the station to provide inexpensive lodging to travelers. This would encourage more frequent travel by providing lodging at a price
point comparable to the low price of the hyperloop ticket.

POWER
18
Power distribution will provide power to onboard electronics by utilizing common Electrical and Electronic System Architecture with an Integrated Electrical Distribution System.
The Primary Power System will efficiently manage and distribute power among known supplies.
The Emergency Power System will consist of backup lithium ion battery packs in case of total power loss.

SAFETY FEATURES
A remotely activated “Pod Stop” command may be sent to the pod in case of emergency.
Pod Stop will place the pod in a safe condition by shutting the air canister valve to slow propulsion and engaging the braking systems.
