Long before 'stimulus' became a taboo word among politicians, the U.S. Federal Government put Americans to work building engineering marvels that cemented the United States as the greatest nation that has ever existed. Chief among these programs was the Works Progress Administration (WPA) which employed millions of Americans during the Great Depression and remains the largest public works program in U.S. history; and what our forefathers accomplished through the WPA and other New Deal programs has yet to be matched. While we may have lost touch with the great American Tradition of Infrastructure Innovation in recent years, we at Transonic believe that the spirit and willingness to work that made these programs successful still exists. Which is why we hope to  continue this tradition of creating engineering marvels by modernizing rail infrastructure using pre-existing technology to provide quicker, more convenient passenger transportation. 

 Transonic’s Hyperloop will be considered among the great engineering marvels in the U.S. such as the Golden Gate Bridge & the Hoover Dam.

How does it work?

In essence, the hyperloop is the purest form of travel physically available to us today. The system eliminates all forms of contact friction, skin drag, form drag, etc. to allow each individual pod to use a minimal amount of energy to travel between two points. This is done by using an enclosed environment in the form of a steel tube and then using pumps to evacuate the environment of air pressure. Once this is done, the pods (suspended by a mag-lev system) are accelerated using a linear induction motor at 32.2ft/s2. This means that for every second that the capsule is accelerating, it is traveling roughly 21mph faster than the previous second until the pod reaches a target cruising speed of 600mph.

Tube

For this system Transonic will use a 10'D Tube, which will be partially evacuated in a closed loop system. The system will be designed for optimal air flow around the capsule, improving performance and energy consumption at the targeted travel speed of 600mph. ASCE, AISC, U.S. DOT, and FRA Code & Regulations will be be taken into consideration, with final designs being submitted to relevant regulatory agencies for final approval. Given that Transonic's tube sections will be custom made in-house, Transonic can provide Hyperloop Infrastructure at $2.75M-$3M cheaper per mile than the leading competition. Operating pressure for this system will be rated at 0.6psia, which will reduce air pressure by 96%. 

Propulsion

The propulsion system will use a LIM (Linear Induction Motor) to accelerate the capsule to cruise speeds, and maintain velocity along the length of the track.

By using two 10’D tubes for two-way traffic, we are allowed an area of 22ft wide for upwards of hundreds of miles. With solar panels expected to produce 8MW/Mile at peak solar activity (significantly more than is needed to power the LIM & vacuum pumps) the power architecture will include a battery array at each accelerator to collect excess energy. These arrays will store excess power that can be drawn from during non-peak periods to ensure that the system remains fully functional regardless of weather conditions. For the acceleration system proposed in the original Hyperloop Alpha White Paper (seen figure), we see how a LIM would be able to work in conjunction with a solar power system to draw energy and accelerate a pod forward. Our LIM design will use this original example as a reference, but will most likely draw influence from the Seraphim-200 LIM design first proposed in 1995 by Sandia National Laboratories due to its ability to recover upwards of 80% of energy originally passing through the capacitors.

Magnetic Levitation

For our mag-lev motors, we will be partnering with Arx-Pax to integrate their MFA Technology for capsule levitation. For more information, follow this link to their website. 

Capsule

The interior of the capsule is designed with passenger safety and comfort in mind. Comfort is primarily achieved by using seats similar to those found in standard HSR systems in the European Union.  Other features to be included in the passenger cabin will be a Federal DOT approved on-board 3AA/3HT oxygen tank, air purifier, HVAC, and cabin pressurization system. For simplicity, we combine these components in a part of the cabin designated for life support. For Model S-01, onboard power will only be used for life support, lighting, OLED LCD display, telemetry, braking, & stability. An emergency evacuation system will also use onboard power, but will be kept separate to ensure that power levels are always at full capacity. Suspension will be recessed into the pod and will support the magnetic levitation system. The open face of the magnets will be flush with the bottom of the pod capsule and will allow the levitation system to achieve an operating height of 0.5”. Loading will be evenly distributed for each mag-lev support to to allow passengers to move around the cabin at their leisure while ensuring uniform operating height throughout the trip. Due to the fact that vibration will not be a significant issue with a magnetic levitation system traveling along a linear route, a more complex suspension will not be necessary.
