Our Pod

"One small step for man, one giant leap for mankind"

Keeping these historic words in mind, we respond to the need for a revolution in the transportation industry. We are a team of motivated students who plan to bring the future to you. Our concept is not limited by the scope of the competition, but is modular and scalable to a full model which can be used for transporting passengers. The modularity of the design will be beneficial in repair and maintenance of the subsystems while in operation. Musk himself has noted the importance of feasibility. To make the Hyperloop a reality we constantly orient ourselves towards a design that is efficient, scalable, cost-effective, and safe.

WE ENGINEER BETTER isn’t just our motto, it’s our call to action.

Aerodynamics

USP and key details: Counter rotating fans (CRfan) bypass flow through the pod while balancing torque, providing a higher pressure ratio, lesser power requirement and lesser weight. The flow is bypassed through a partial annular nozzle which keeps the flow attached while providing a flush finish on the pod floor. The cold air from the nozzle is used to cool the braking system.

CR fan configuration with the partial annular nozzle will be looked into more detail in future development. For the competition in June, a simpler design which can be easily manufactured is being worked on with inputs from SpaceX about safety and design simplifications. This modification will reduce the pod weight further which will reduce the cost.

Structures

This hyperloop pod design has a modular structure with a disjoint engine and payload area. The payload structure is strong enough to sustain the crash loads while the engine structure is designed to buckle and act as an impact attenuator during a crash thus protecting the payload. The crash criteria is assumed considering the g forces that a human body can tolerate during a crash. A common mount is designed for the levitation and its fail safe that prevents the levitation device from ever crashing on the track.

Modular structure with engine area and passenger area being separate. The passenger area designed for strength while the engine area has been designed for lower buckling strength and hence acts as crumple zone in case of crash.

Electronics

Our transponics system is responsible for the design and development of levitation, electrical and electronic systems for the pod. These include electromagnetic, electric circuit, sensor integration and embedded software sub-systems. Magnetic levitation is achieved using the Arx Pax hover engines. Military grade Inertial Navigation Systems (INS) is used to obtain the attitude of the pod. Other sensors such as laser range finders, temperature, pressure, battery and optical sensors are also used in our pod sensor suite.

Dynamics and Controls

We understand the dynamics of the pod and building mathematical models of the pod. Using these models, we develop the brain or the control system for the pod. The control system takes inputs from the sensors, processes them and provides necessary control outputs to actuators that ensure the stability of the pod, levitates and propels it as desired.
