Supersonic Airplane Travels 5 Times the Speed of Soun

France and Japan presented at the Paris Air Show Le Bourget a supersonic aircraft that could fly from Paris to Tokyo in two hours and a half.

This is the ZEHST (Transportation Hypersonic Zero Emission), which would reach 5 000 kilometers per hour, five times the speed of sound, but with low emissions because it would use biofuels.

The ZEHST carry between 60 and 100 passengers. The aircraft is being developed in collaboration with experts from Japan and may become “the standard of the companies in 2050,” said the head of EADS technologies and innovation, Jean Botti.

The plane will take off in a conventional manner by two turbojet engines. 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 rocket. Once reached the 23 km high, the reactors will help to reach 5,000 km / h. The landing will also be done in a classical way. (BG)
