Supersonic jets: return to the past? 

The EADS prototype reached a speed of 5,000 km per hour and linking Paris and Tokyo in 2 hours and a half

European aircraft consortium EADS owner of the aircraft manufacturing subsidiary of Airbus,  present at the last  Le Bourget Air Show, announced the project a supersonic aircraft capable of linking Paris and Tokyo in two hours, compared to eleven today.

For now, only the manufacturer will unveil the model of future aircraft , which aims to fly in 2050 and will be capable of reaching 5,000 kilometers hour , more than four times the speed of sound, with low exhaust emissions pollutants through the use of biofuels. 

EADS says the new supersonic model of which will be presented eight years after he left to fly the Concorde, the latest draft of commercial apparatus capable of breaking the sound barrier , you can transport 60 to a hundred passengers, compared to 120 in its predecessor. Dubbed  ZEHST (Zero Emisssion Hypersonic Transportation),

Along with his extraordinary performance of Speeddouble the Concorde , responsible for the project include low emission levels, thanks to the use of biofuels, hydrogen and oxygen. In addition, ensure that  , about 32 kilometers , compared with 11 miles of today’s commercial flights or 18 of the previous supersonic. 

The aircraft will take off in a conventional manner by two turbojet fed biofuel made from marine algae. Once reached the 5 km altitude, three engines powered by a mixture of hydrogen and oxygen will take over, aided by a third reactor designed from the technology used in the Ariane rockets. The plane then achieved a speed 2.5 times that of sound, most of which achieved the Concorde.

But when the unit reaches 23 miles high, five miles more than achieved the legendary supersonic jets coming online that will reach 5,000 kilometers per hour, the cruising speed of the device. Landing powered by turbojets. Funding for the project will require European support within a community program to reduce pollution.

hour and a half

EADS considers that the plane will target businessmen and the ticket prices will be about 6,000 U  8,000 euros for a journey between Paris and  , which made hour and a half , compared to nearly eight current or the three required by the Concorde.
