VEHICLES WITH THE CUSHION OF AIR
Vehicles on a pillow of air (or her ship named și pernopter) moving
above the water or soil through the cushion of air created under taken with the
help of powerful fans. This cushion is formed by jets of air in refloat large
amount of pressure și with a installation fan blower. Jets of air are directed to
the surface of water through the nozzle acetate on the periphery vehicle.
Cushion of air has the 0.5-5 m3, function the tonnage vehicle speed, work
surface of continuity etc. Vehicles with air cushion pay multiple: high-speed
travel, resistance by advancing small, consumption than fuel, the possibility of a
pass over areas with one small dry land or injured.
Work synthesizes presentation vehicles the cushion of air, advantages
and disadvantages, a short historical as well as și examples of their use. The
future is completely favourable this means of transport the water și on land
raised și accessible.

SUBWAY
Most large towns and cities in the world, trying to solve urban transport
as efficiently as low pollution.
Travel by Metro provides commercial speed of 30-45 km/h, with traffic
up to 90 s duration between two trains, a maximum transport 10,000
passengers per train (of 6 cars) and distances between stations of 600-1000 m.
In recent years, have built automated metro systems without conductor/driver,
which are directly controlled from a control centred. It is estimated that one
kilometre of underground line costs 30 million Euros.
It presents some generalities on the metro, public transport it, looking
at the short subways in London, Budapest, Paris, Madrid and Bucharest.

HIGH-SPEED TRAIN
High-speed trains are trains may grow higher speeds of 200 km/h,
normally, their speed of between 200 km/h and 300 km/h.
Time has proved that movement Romania on the railway was not
merely a utopia as there was no ambition somewhat because of brave in
search of Nov get, but a very necessary adjustment to the requirements
weather. Big și briefly trains, have a form hours, perfectly smooth, with
suspensors on cushions of air și facilities technological contemporary because
passengers feel comfort during a trip that takes very little because speed of up
to 200-220 km/h. Family trains high-speed has members in a growing number
of countries and the future is very promising.
