Hyperloop - The future of Transportation


Published on

Hyperloop is the new mode of transportation after air, water, rails and roads. It could be a realistic high speed as well as economical way of transportation apart from a fantasized means of transportation called the "teleportation".

Hyperloop - The future of Transportation

  3. 3. INTRODUCTION The intent of the project was to develop the fastest mean of transportation which would transport passengers at a remarkable speed of 1220 Km per hour. The existing modes of transportation including air, rail, road and water are either expensive or slow or a combination of both.
  4. 4. WHO’S IDEA ? Elon Musk
  6. 6. PROPULSION Based on the same principle as maglev. Gives the right amount of starting acceleration to the capsule. Consume an average of 21MW which is generated by solar panels.
  7. 7. TUBE Contain capsules. Made of steel which ensures ease of build because they can be welded easily. The tube ensures reduction of shock waves generated due to travelling at a very high speed.
  8. 8. CAPSULE Carry passenger as well as vehicles thus two capsules are build: a) Passenger only mode. b) Passenger plus vehicle mode.  Can Carry 28 passengers at time.  Frequency – every 2 minutes
  9. 9. COMPRESSOR  Most important part.  Helps to reduce air drag.  Concept:- aerodynamic drag increases with square of speed and power requirement increases as cube of speed INITIAL FINAL SPEED: ‘x’ SPEED: ‘2x’ AIR-DRAG: ’ y’ AIR-DRAG: ’4y’ POWER REQIREMENT: ‘z’ POWER REQIREMENT: ‘8z’
  10. 10. PYLONS  Tall tower-like structures.  Prevents earthquakes by thermal expansion and dampened lateral slip.  Low land requirement.
  11. 11. AIR BEARINGS  Air from compressors is passed on to air bearings. Speed of Hyperloop is magnificently increased because the friction is drastically reduced.  Similar to air hockey table.
  12. 12. CHALLENGES FACED CHALLENGE 1: Kantrowitz limit The speed limit for an object passing through a tube, at the point where the air in front of the object kind of bunches up and can no longer flow around the object. SOLUTION: Whenever we have a capsule moving at a high speed through a tube containing air, there is a minimum tube to capsule area below which we will choke the flow What this means is that if the walls of the tube and the capsule are too close together, the capsule will behave like a syringe and eventually be forced to push the entire column of air in the system, which isn’t good.
  13. 13. The approach that we could use to overcome this Kantrowitz limit is to mount an electric compressor fan on the nose of the pod that actively transfers high pressure air from the front to rear of the vessel this is like having a pump in the head the syringe actively releasing pressure. CHALLENGE 2: FRICTION There is another problem simultaneously to solve, this is how to create a low friction suspension system when travelling at over 700 mph. SOLUTION: Wheels don't work well at that sort of speed, but a cushion of air does. Air bearings, which use the same basic principle as an air hockey table. We can use vacuum to totally reduce air drag but it is not possible to create vacuum for so long distance so tubes are filled with low pressure air.
  14. 14. CHALLENGE 3: POWER SOLUTION: The pod will be propelled with the help of magnetism. Now magnetism requires electricity. This electricity will be provided by solar energy. Hence the Hyperloop promotes in green technology transportation too. Solar panels will be along the tube i.e. on top of the HYPERLOOP. These panels will generate 120W per sq. meter. The average energy generated will be 57MW per year which is more than the HYPERLOOP will use.
  15. 15. Why do we need Hyperloop?
  17. 17. CONCLUSION With the increase in population and pollution, there has been a thriving demand for a technology that not only revolutionizes the world with its speed but also keeps in mind the impact it imparts to the environment. Hyperloop could be the cleanest, fastest, cheapest and the latest means of transport. The development in this new venture is encouraged by the very fact that it is open-source.
