The Hyperloop is a proposed mode of transport involving capsules that would travel in low-pressure tubes at high speeds of over 700 mph, proposed by Elon Musk as an alternative to high-speed rail or air travel. The concept involves capsules holding passengers that would be accelerated via linear accelerators in tubes elevated on pylons, powered by solar energy. Key components would include the capsule, tube, propulsion via magnets and rotors, and an initial route between Los Angeles and San Francisco. Technical challenges include maintaining low pressure in the long tubes and developing a suspension system for the capsules to move at such high speeds without friction.

- 1. Hyper Loop Train THE FUTURE OF TRANSPORTATION?
- 2. What is it?
- 3. HYPERLOOP: Hyperloop is a new mode of transport? Proposed by ELON MUSK American business magnate, investor, and inventor. He is currently the CEO & CTO of spaceX and CEO & chief Product Architect Tesla Motors. A high speed train that promises travel at twice the speed of a commercial aircraft, transporting passenger from one place to another place.
- 4. The Concept
- 5. The concept: A capsule full of people in a low pressure tube Elevated on pylons goes really fast from Los Angeles to San Francisco
- 6. Components of Hyperloop transport system 1. Capsule 2. Tubes 3. Propulsion 4. Route
- 8. Tube : Tube is made of steel. The two will be welded together in a side by side configuration to allow the capsules to travel both directions. Pylons are placed every 100 ft (30 m) to support the tube. Solar arrays will be cover the top of the tubes in order to provide power to system.
- 9. Contd; The inner diameter of the tube is optimized to be 2.23 m which is small enough to keep material cost low while large enough to provide some alleviation of choked air flow around the capsule. The tube cross section area is 42.2 ft^2 giving a capsule/tube area ratio of 36% or a diameter ratio of 60%.
- 10. Hyperloop capsule In tube with attached solar arrays
- 11. Propulsion: Linear accelerations are constructed along the length of the tube at various locations to accelerate the capsule. Stators are located on the capsules via the linear acceleration.
- 12. Rotor and Stator 3D diagram
- 13. Route: At present there will a station at Los Angeles and San Francisco along with the way will be possible with splits in the tube. The majority of the route will follow highway and the tube constructed in the median.
- 14. Suspension: Suspending the capsule within the tube presents a substantial technical challenge due to transonic velocities. Convectional wheel and axle system become impractical at high speed due to friction losses and dynamic instability. A viable technical solution is magnetic levitation. An solution is an air bearing suspension.
- 15. Air bearings offer stability and extremely low drag at feasible cost by exploiting the ambient atmosphere in the tube. When the gap is high between a ski and the tube walls reduced the flow field in the gap exhibits non linear reaction resulting in large restoring pressures. The increased pressure pushes the ski away from the wall allowing it to return at basic height.
- 18. Advantages ; Fast (air) Environmental friendly (rail ,cars) Inexpensive (air) Sustainable (use solar energy) Runs through the median of existing highway Ready when the passenger is ready to travel.
- 19. Problems; Tube pressurization. Turning will be critical (with large radius). Less movable space for passenger.
- 21. Hyperloop capsule with passengers
- 22. Conclusion: As it has number of advantages it will very helpful for transport public as well as goods in a very short time ( at top speed of 1220 kmph) and also in low cost. It is new concept so there is some future work will be required for development of this project.
