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.

EXHAUST VECTOR

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.

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.

17

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.
