Hyperloop

  1. 1. Presented by, NIRANJAN, 1ST SEM, M TECH (TE), NIT WARANGAL. 1
  2. 2. 1. RAIL relatively slow and expensive 2. ROAD relatively slow 3. WATER relatively slow 4. AIR expensive 2
  3. 3. PIPELINE ? 3
  4. 4.  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 of Tesla Motors.  A high-speed train that promises travel at twice the speed of a commercial aircraft, transporting passengers from Los Angeles to San Francisco in just 30 minutes. 4
  5. 5.  A high-level alpha design for the system was published on August 12, 2013, in a whitepaper posted to the Tesla and SpaceX blogs.  Musk has also said he invites feedback to "see if the people can find ways to improve it"; it will be an open source design, with anyone free to use and modify it. 5
  6. 6.  A Hyperloop would be "an elevated, reduced-pressure tube that contains pressurized capsules driven within the tube by a number of linear electric motors.”  This system can achieve an average speed of 598 mph (962 km/h), and a top speed of 760 mph (1,220 km/h). 6
  7. 7.  Hyperloop consists of a low pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube. Hyperloop conceptual diagram. 7
  8. 8. Hyperloop tube stretching from Los Angeles to San Francisco. 8
  9. 9.  Passengers may enter and exit Hyperloop at stations located either at the ends of the tube, or branches along the tube length. 9

  11. 11.  Sealed capsules carrying 28 passengers each that travel along the interior of the tube depart on average every 2 minutes from Los Angeles or San Francisco (up to every 30 seconds during peak usage hours).  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. 11
  12. 12.  The capsules are accelerated via a magnetic linear accelerator affixed at various stations on the low pressure tube with rotors contained in each capsule. Hyperloop passenger capsule subsystem notional locations (not to scale). 12
  13. 13.  For travel at high speeds, the greatest power requirement is normally to overcome air resistance.  Aerodynamic drag increases with the square of speed, and thus the power requirement increases with the cube of speed.  For example, to travel twice as fast a vehicle must overcome four times the aerodynamic resistance, and input eight times the power. 13
  14. 14.  Just as aircraft climb to high altitudes to travel through less dense air, Hyperloop encloses the capsules in a reduce pressure tube.  The pressure of air in Hyperloop is about 1/6 the pressure of the atmosphere on Mars.  This is an operating pressure of 100 Pascal’s, which reduces the drag force of the air by 1,000 times relative to sea level conditions and would be equivalent to flying above 150,000 feet altitude 14
  15. 15.  The capsules are separated within the tube by approximately 23 miles (37 km) on average during operation.  The capsules are supported via air bearings that operate using a compressed air reservoir and aerodynamic lift. 15

  20. 20. Streamlines for capsule traveling at high subsonic velocities inside Hyperloop. 20
  21. 21.  The tube is made of steel. Two tubes 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 cover the top of the tubes in order to provide power to the system. 21
  22. 22.  The inner diameter of the tube is optimized to be 7 ft 4 in. (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-sectional area is 42.2 ft2 (3.91 m2) giving a capsule/tube area ratio of 36% or a diameter ratio of 60%. 22
  23. 23. Hyperloop capsule in tube cutaway with attached solar arrays. 23
  24. 24.  high-speed transport more generally, have historically been impeded by the difficulties in managing friction and air resistance, both of which become substantial when vehicles approach high speeds.  vactrain concept : tubes kept at a complete vacuum, allowing for theoretical speeds of thousands of miles per hour. 24
  25. 25.  The expected pressure inside the tube will be maintained around 100pa (less pressure).  This low pressure minimizes the drag force on the capsule while maintaining the relative ease of pumping out the air from the tube. 25
  26. 26.  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. 26

  28. 28.  There will be a station at Los Angeles and San Francisco. Several stations along the way will be possible with splits in the tube.  The majority of the route will follow highway and the tube will be constructed in the median 28

  32. 32.  Ready when the passenger is ready to travel (road)  Inexpensive (road)  Fast (air)  Environmentally friendly (rail/road via electric cars)  Sustainable (uses solar energy)  Runs trough the median of existing highway 32
  33. 33.  A number of economists and transportation experts have expressed the belief that the US$6 billion price tag dramatically understates the cost of designing, developing, constructing and testing an all-new form of transportation. 33
  34. 34.  In 1812 the British mechanical engineer and inventor George Medhurst wrote a book detailing his idea of transporting passengers and goods through air-tight tubes using air propulsion.  Atmospheric railways were built in Ireland and England, most notably the London and Croydon Railway, the first stage opening in 1846.  The Crystal Palace pneumatic railway operated around 1864 and used large fans, some 22 feet (6.7 m) in diameter, that were powered by a steam engine. The tunnels are now lost but the line operated successfully for over a year. 34
  35. 35.  In the 1910s, vacuum trains were first described by rocket pioneer Robert Goddard. While Hyperloop has significant innovations over early proposals for reduced pressure or vacuum-tube transportation apparatus, the work of Goddard "appears to have the greatest overlap with the Hyperloop."  Swissmetro was a proposal to run a maglev train in a low pressure environment. Concessions were granted to Swissmetro in the early 2000s to connect the Swiss cities of St. Gallen, Zurich, Basel and Geneva. Studies of commercial feasibility reached differing conclusions and the vactrain was never built. 35
  36. 36.  Hyperloop is a new idea of solar powered transportation system with high speed of up to 800mph, which is developed by US entrepreneur Elon Musk.  He proposed this transportation system to the route from the Los Angeles region to the San Francisco Bay Area. In this presentation, the possibilities and construction of the system is explained with the details of different components of the system.  The technical details of the Hyperloop in this presentation are based on the design details released by Elon musk on 12th august, 2013. 36
