This document discusses the proposed Hyperloop transportation system. It describes Hyperloop as comprising a sealed tube through which passenger pods can travel at both low and high speeds. The key components of Hyperloop include the low pressure tube, passenger capsules, axial compressors for propulsion, and an air bearing-based suspension system. Safety features include maintaining a low pressure environment within the sealed tube to reduce air resistance and allow high speeds, as well as integrating propulsion controls to only allow safe acceleration in each tube section. Advantages of Hyperloop include high speed travel that is faster, cheaper, and more sustainable than existing options.

3.  Today’s conventional modes of transportation consists of
four unique types: rail, road, water and air.
 Hyperloop is a proposed transportation system it
comprises a sealed tube through which a pod may travel.
 The capacity would be on average 840 passengers per
hour.

Figure 1: Conceptual Design of Hyperloop
Hyperloop consists of a low pressure tube with capsules that are
transported at both low and high speeds throughout the length of the
tube.

7.  The tube is made of steel.
 It creates vacuum environment.
 Pylons are placed every 30m to support the tube.
 The tubes designed to withstand earthquakes.
 The closed loop tube will be mounted side-by-side on elevated
pillars.
 A solar array covering the entire Hyperloop is large enough to
provide an annual average of 57 MW.

Figure 3: Hyperloop Passenger Capsule
 Sealed capsules carrying 28 passengers.
 The capsules are supported via thrust air bearings that operate
using a compressed air reservoir and aerodynamic lift.
 Capsule diameter is 2.7m and 100feet long.

Figure 4: Streamlines for capsule travelling at subsonic
velocities inside Hyperloop
 It avoids kantrowitz limit.
 Air is compressed with a pressure ratio of 20:1.
 A part of compressed air is exhausted through the air bearings
and Some air is stored for passenger .
 An onboard water tank is used for cooling of the air.

 Accelerate the capsule from 0 to 480 kph for relatively low speed.
 Maintain the capsule at 480 kph, during ascents over the
mountains.
 To accelerate the capsule from 480 to 1,220 kph at the beginning of
the long coasting section.
 To decelerate the capsule back to 480 kph at the end of the I-5
corridor.
Hyperloop uses a linear induction motor to accelerate and
decelerate the capsule.
 Each accelerator has two 70 MVA inverters.

 Thrust air bearings offer stability and extremely low drag.
 Compressor pressurized air and aerodynamic lift provide better
lift to capsule.
 Independent mechanical suspension are provide for smooth ride
for passengers.

 The tube will be supported by pillars.
 The spacing of the pillars critical to achieve the design
objective of the tube structure.
 The average spacing is 30 m.
 25,000 pillars supporting both Hyperloop tubes and
overhead solar panels.
 It is 6 m tall whenever possible but may vary in height in
hilly areas.

 Capsules travel in a carefully controlled and maintained tube
environment making the system is immune to wind, ice, fog,
and rain.
 The propulsion system is integrated into the tube and can
only accelerate the capsule to speeds that are safe in each
section.

 Hyperloop could transport people, vehicles, and freight between
Los Angeles and San Francisco in 35 minutes.
 Additional technological developments and further optimization
could likely reduce the price.
