HYPER LOOPTHE FIFTH FORM OF TRANSPORTATION
hyper loop
hyper loop
Hyper loop concept was invented and designed in 1812 by
the British Mechanical Engineer George Wenger
The concept of hyper loop is now developed and designed by
the billionaire Elon Musk in 2012
While the term Hyper loop is in some countries a registered
trademark of the Space Exploration Technologies Corporation
(Space X) for the high speed transportation in partially
evacuated tubes, the Hyper loop concept has been explicitly
open-sourced by Musk and Space X, and others have been
encouraged to take the ideas and further develop them.
This system can achieve an average speed of 598 mph
(962 km/h), and a top speed of 760 mph (1,220 km/h).
Simply it have the same working principle of Air Hockey
The pods would accelerate to cruising speed gradually using a linear
electric motor and glide above their track using passive magnetic
levitation or air bearings.
It is levitated and propelled forward using powerful electromagnets.
This itself considerably reduces losses due to friction, as the train is
literally gliding over the track and is not in contact with the track
Hence there are no frictional losses allowing the train to move at high
velocities. The absence of air in the hyper loop will further increase the
efficiency by nearly eliminating losses due to air drag and make it
much faster.
The capsules are supported on a cushion of air, featuring pressurized
air and aerodynamic lift.
WORKING PRINCIPLE OF HYPER LOOP
Residual air in the tube is captured, compressed, and forced
through holes in skis attached to the bottom of the capsule. The
gap between the skis and the tube during operation is between
0.5mm and 1.3mm
The air pressure in the tube is very low, a capsule traveling at
700mph will cause significant air pressure at the nose of the
vehicle, which must be considered in the design. Since the tube has
a larger cross-section than the capsule, some air flows around the
vehicle.

  • 12.  Sealed capsules carrying 28 passengers each that travel along the interior of the tube.  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. 12
  • 13. The capsules are accelerated via a magnetic linear accelerator affixed at various stations on the low pressure tube with rotors contained in each capsule. 13 Hyperloop passenger capsule subsystem notional locations (not to scale).
  • 14.  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. 14
  • 15.  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 15
  • 16.  The capsules are separated within the tube by approximately 23 miles (37 km) on average during operation. 16  The capsules are supported via air bearings that operate using a compressed air reservoir and aerodynamic lift.

  • 24.  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. 24

  • 26. 26  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%. 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.
  • 28.  Vactrain concept : tubes kept at a complete vacuum, allowing for theoretical speeds of thousands of miles per hour.  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. 28
  • 29.  Linear accelerators are construct various along the length of the tube at locations to accelerate the capsules.  Stators are located on the capsules to transfer momentum to the capsules via the linear accelerators.

  • 39. 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. In the 1910s, vacuum trains were first described by rocket pioneer Robert Goddard. While Hyper loop 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 Hyper loop." Swiss metro was a proposal to run a maglev train in a low pressure environment. Concessions were granted to Swiss metro 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. 39
