  3. 3. What is Hyperloop ?
  4. 4. What is Hyperloop ?  It is the new form of transportation between long distances  Hyper loop consists of a low pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube.  It is an high speed train transporting at a speed of 800mph which is twice the speed of a commercial plane.

  8. 8. HISTORY Due to high traffic US government proposed a high speed train project between San Francisco to Los Angeles In past Robert Goddard proposed using vacuum as medium of transport there by attain speed without high friction losses but there’s lot of possibility of leaks . And when there is a leak it will damage the whole system. Elon Musk thought of overcoming it with maintaining low pressure rather than vacuum and using electromagnetic suspension.
  9. 9. THE CONCEPT

  11. 11. ARTIST RENDERINGS and GEMOETRY
  12. 12. DESIGN The Hyperloop concept is proposed to operate by sending specially designed "capsules" or "pods" through a continuous steel tube maintained at a partial vacuum. Each capsule floats on a 0.5-to-1.3- millimetre (0.02 to 0.05 in) layer of air provided under pressure to air-caster "skis", similar to how pucks are suspended in an air hockey table, thus avoiding the use of maglev while still allowing for speeds that wheels cannot sustain. Linear induction motors located along the tube would accelerate and decelerate the capsule to the appropriate speed for each section of the tube route. With rolling resistance eliminated and air resistance greatly reduced, the capsules are theorized to be able to glide for the bulk of the journey. In the Hyperloop concept, an electrically driven inlet fan and air compressor would be placed at the nose of the capsule in order to "actively transfer high pressure air from the front to the rear of the vessel," resolving the problem of high speed transport in a tube that is not a hard vacuum, wherein pressure builds up in front of the vehicle, slowing it down.[2] A fraction of the air is shunted to the skis for additional air pressure, augmenting that gain passively from lift due to their shape. In the alpha-level concept, passenger-only pods are to be 2.23 metres (7 ft 4 in) in diameter[2] and projected to reach a top speed of 760 mph (1,220 km/h) so as to maintain aerodynamic efficiency;[citation needed] the design proposes passengers experience a maximum inertial acceleration of 0.5 g, about 2 or 3 times that of a commercial airliner on takeoff and landing. At those speeds there would not be a sonic boom; with low-pressure warm air inside the tubes, Musk hypothesizes the pods could travel at high speeds without exceeding Mach 1.[25]
  13. 13. COMPONENTS OF HYPERLOOP CAPSULE TUBE PROPULSION
  14. 14. The maximum width is 4.43 ft (1.35 m) and maximum height is 6.11 ft (1.10 m). With rounded corners, this is equivalent to a 15 ft2 (1.4 m2) frontal area, not including any propulsion or suspension components.
  15. 15. COMPRESSOR • One important feature of the capsule is the onboard compressor, which serves two purposes . This system allows the capsule to traverse the relatively narrow tube without choking flow that travels between the capsule and the tube walls • by compressing air that is bypassed through the capsule. It also supplies air to air bearings that support the weight of the capsule throughout the journey.
  16. 16. THE TUBE  The tube is made of steel.  Solar arrays will cover the top of the tubes in order to provide power to the system.  The tube cross-sectional area is 42.2 ft2 (3.91 m2) giving a capsule/tube area ratio of 36% or a diameter ratio of 60%.
  17. 17. TUBE CONSTRUCTION • The tube will be supported by pillars • Average spacing is 30m between each pillar • There will be roughly 25000 pillars for a distance of 680 kilometers • Built using reinforced concrete • Tunneling mountains to kept the route straight.
  18. 18. PROPULSIONS Linear accelerators are constructed along the length of the tube at various locations to accelerate the capsules. Stators are located on the capsules to transfer momentum to the capsules via the linear accelerators. Capsules are accelerated by linear magnetic induction and decelerated by regenerative braking similar to magnetic levitation trains. The Hyperloop uses a linear induction motor to accelerate and decelerate the capsule. This provides several important benefits over a permanent magnet motor
  19. 19. WORKING
  20. 20. Best guess at how the Hyperloop could work based on all of the clues. Cars would share the tube with the air column only during high speed run between stations. Before deceleration, the air column is shunted to the return tube. The car is slowed by linear regenerative breaking, accelerated by linear magnetic induction(rail gun)- John Gardi
  21. 21. SUSPENSION Suspending the capsule. Magnetic levitation. An alternative to these conventional options is an air bearing suspension. non-linear reaction resulting in large restoring pressures The increased pressure pushes the ski away from the wall, allowing it to return to its nominal ride height

  30. 30. LIMITATIONS When we use less pressure instead of vacuum then we need to increase the diameter of tube or go slow or really , really fast. But increasing speed that high will become very much expensive. A battery can’t store enough energy to power fan over whole journey so a linear electric motor, a round induction motor rolled flat is provided. Due to high
