- 5. PROPULSION We 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. 5 Exhaust Nozzle Electrically controlled valve Structural Bracing Air Canister 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.
- 6. 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. Propulsion / Stabilization System Concept Vertically Mounted Wheels Horizontally Mounted Wheels 6
- 7. NAVIGATION The 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
- 8. BRAKING The 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. Braking System Concept 8 Calipers Disc
- 9. 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. Possible Air Bearing and Maglev Designs 9
- 10. COMPUTER SYSTEM OVERVIEW The embedded computer system will continuously assess, manage, and adjust the status of the pod and provide external communications capabilities. Computer System Top Level Diagram 10 External Control System Primary Pod Control System Secondary Pod Control System
- 11. 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. 11 Drive Control Power Electronics Body control Brake Systems Propulsion System Wheel System Control System, Feedback & Monitoring Accelerometer Gyroscopes Excess Heat Proximity Sensors Instrument cluster Operator touch Screen Telemetry Devices Power Control Power Storage / Distribution Battery Recharge HVAC Pod Control System Emergency Shutdown Command Navigation & Communication General Navigation Positioning Network Communication CISCO IW3700

- 13. 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. 13 RTOS Overview
- 14. 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
- 15. MODULAR PAYLOAD The 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.
- 16. MODULAR PAYLOAD A 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.
- 17. MODULAR PAYLOAD The 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
- 18. 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. 24v Photoelectric Sensor 24v Propulsion Actuator 24v Braking Control 24v Electric Motors 24v Wireless Access Point 5v Proximity Sensor 5v Accelerometer 5v Gyroscope3.5v Pressure / Temp Electrical Loads by Subsystem
- 19. HAZMAT / STORED ENERGY The lithium contained within the battery will be the only hazardous material / stored energy onboard the pod. 19
- 20. 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.
