Investment
project «String transport systems»
Investment project "String transport systems" (STS) is the
principally new high-speed transport system. Rail-strings are the basis
of the STS, in which strings are stretched to the total strain of 100...500
tons and rigidly secured to anchored supports placed with the step of 0.5...5
km. The transport line, having two rails, is upheld in spans by intermediate
supports with the step of 20...100 m. depending upon the relief. The STS
route structure requires little materials. For example, the consumption
of materials for the one-way route will be within the limits of 50...100
kg/m and this is equal to the quantity of material for a one rail of the
common railway. The consumption of the reinforced concrete is also low:
0.2...0.5 m3/m. The STS is not critical to the terrain relief as since
the height of supports can amount to 50...100 m, that allows to smooth
the relief of the crossed area. Routs can pass through the area of mountains
at an angle of 30° and more to the skyline, and the length of spans
without supports, for example over the canyon, can amount to 5 km.
Vehicles will easily achieve the speed of 300...500 km/h due to the
high directness of the rail-string (it has no deflections and joints along
its length) and its dynamic rigidity, that is ensured by both constructional
decisions and technological techniques. Aerodynamics of vehicles has been
analyzed and the body of the vehicle was designed having unique aerodynamic
properties (there is no analogue to it in other kinds of high-speed transports)
- the aerodynamic resistance factor Cx=0.075 was obtained during the blowing
through in the wind tunnel. For this reason the electric motor with the
output of 100 kW will provide the speed of 300...350 km/h for ten-seat
vehicle; the output of 200 kW - 400 km/h, of 300 kW - 500 km/h.
The dynamics of route and vehicle vibrations was theoretically researched
in the velocity range of 100...1000 km/h. Solutions were discovered, ensuring
the movement along the route without resonance with relative amplitudes
of its oscillation within I/I.000...1/10,000. Thus, the STS route, requiring
little materials, nevertheless will have higher operating characteristics
than contemporary road-transport and railway bridges and overpasses that
are characterized by big quantity of materials for their erection.
On sea areas the STS route can pass over at the height of 10...50 m
above sea-level (the sea depth up to 50 m) or can be placed in the pipe
2.5...3 m in diameter with zero floating and situated at the depth of 10...100
m.
STS routes will be less expensive then common and high-speed railways,
highways, one-rail roads and magnetic suspension trains due to their requiring
of less material, technological production and assembling, the use of traditional
materials in structures of routes and supports. One kilometer of a double-route
track in serial production will cost 1...2 million US$ - on land areas;
2...3 million USS - on sea areas (the route is situated above sea level)
and 5...10 million US$ - the route is situated in the pipe.
The STS route will require small area of vacated land (less then O.I
hectare/km, the same as for a walking path or a trail), at tlie same time
it does not need embankments, tunnels, bridges or conduits, there is no
need in telling of trees and demolition of buildings.
The cost for transportation of a passenger over land area of the STS
route at a distance of 1.000 km.will be: 20...25 USD (at 20.000 passengers
during 24 hours), 10...15 USD (at 50,000 passengers during 24 hours), 5...10
USD (at 100.000 passengers during 24 hours).
It follows from produced advantages of the STS that under other equal
conditions (equal speed, carrying capacity, terrain relief, etc.), it will
be the cheapest and ecologically safe transport from all existing and future
(electric-cars, shield-flights, etc.) kinds of transport.
It is necessary to continue scientific-research and design works and
to erect the pilot route with the aim to fulfill the STS project.
Needed volume of investments depends upon the range of scientific-research
and design works and the length of the pilot route (model part of the route)
- from 1.0 to 10 million USD.
The cost of the STS projection can be compensated if there is an order
to design and erect the concrete route only 10 km in length (for example
"town - airport"). The difference in cost between common roads
and the STS route will cover the cost of scientific-research and design
works. The transport system will vield a profit of 50.000... 500.0OO USD/km
depending upon its carrying capacity and the terms of cost compensation.
