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 Tesla Motors.
A high speed train that promises travel at twice the speed
of a commercial aircraft, transporting passenger from one
place to another place.
Tube is made of steel. The two 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
Solar arrays will be cover the top of the tubes in
order to provide power to system.
The inner diameter of the tube is optimized to be
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 section area is 42.2 ft^2 giving a
capsule/tube area ratio of 36% or a diameter ratio
Hyperloop capsule In tube with attached solar arrays
Linear accelerations are constructed along the
length of the tube at various locations to accelerate
Stators are located on the capsules via the linear
At present there will a station at Los Angeles
and San Francisco along with the way will be
possible with splits in the tube.
The majority of the route will follow highway
and the tube constructed in the median.
Suspending the capsule within the tube presents
a substantial technical challenge due to transonic
Convectional wheel and axle system become
impractical at high speed due to friction losses
and dynamic instability.
A viable technical solution is magnetic levitation.
An solution is an air bearing suspension.
Air bearings offer stability and extremely low
drag at feasible cost by exploiting the ambient
atmosphere in the tube.
When the gap is high between a ski and the tube
walls reduced the flow field in the gap exhibits
non linear reaction resulting in large restoring
The increased pressure pushes the ski away from
the wall allowing it to return at basic height.
Environmental friendly (rail ,cars)
Sustainable (use solar energy)
Runs through the median of existing highway
Ready when the passenger is ready to travel.
Turning will be critical (with large radius).
Less movable space for passenger.
As it has number of advantages it will very
helpful for transport public as well as goods in a
very short time ( at top speed of 1220 kmph) and
also in low cost.
It is new concept so there is some future work
will be required for development of this project.
