We are adapting constantly to be better than before - that has not changed in the 2020-2021 season. Our pod has been revamped with a new propulsion system as well as an updated fairing design.
This year, the propulsion team transitioned from our optimized cold gas thrusters to a three phase, double-sided linear induction motor (DSLIM). This method of propulsion better aligns with our vision for a full scale Hyperloop pod.
Through rigorous research, consultation with industry experts, and UW faculty advisors, the propulsion team has developed an efficient and safe system to provide a reliable driving force for the pod.
The braking team's design this year utilizes hydraulic pressure to actuate the braking calipers. The goal of this design is to build hydraulic pressure quickly while minimizing fluid displacement.
The hydraulic and mechanical systems will be connected using flexible hosing routed around the back edge of the chassis directly to each caliper.
The stability team is responsible for the pod-to-track interface, ensuring that the pod stays centered around the I-beam while minimizing friction and eliminating forces or impulses from track irregularities. This is accomplished through a combination of wheels, springs, linkages, and damping, which are mounted directly to the chassis.
The structures team is responsible for designing and manufacturing the pod's chassis, fairing, and additional substructures including the fairing mounts and the battery boxes.
Instead of unidirectional prepreg Carbon Fiber Reinforced Polymer (CFRP), dry woven carbon fiber will be used in conjunction with a liquid epoxy resin and hardener system during the layup for the fairing.
The control and power team worked to supply power to the pod and monitor pod functions. First, power needs to be delivered to the valves, solenoids, circuitry, and the linear induction motor. Once everything is powered, the controls side of our subsystem monitors the pods attached sensors to ensure all of our systems are operating properly. The goals of these two subsystems is to make sure the pod is powered for the entirety of the run, and that it reaches its destination safely or stops early if malfunctions occur.
