A Paris - New York in 57 minutes by 2030 through a hypersonic aircraft?

For over eight years, European companies are endeavoring to create a hypersonic aircraft capable of carrying hundreds of passengers. The latter is expected to join Paris to New York in less than an hour. Nearly 13 years after the Concorde crash, many European companies are currently working on the creation of a hypersonic aircraft capable of carrying 300 people and travel at speeds of up to Mach 5 Mach 8. Called Lapcat ("Long-Term Advanced Propulsion Concepts and Technologies") This European project is the contribution of the European Space Agency (ESA). A semi-spaceflight According LesEchos.fr, such a machine could be created over the next 20 years, thanks to the progress made by the British company Reaction Engines, working on a concept derived space launchers. The plane, by the name of A2 and measuring 139 meters long, would be powered by engines powered by oxygen and hydrogen. In the atmosphere, it would use the oxygen in the air before relying exclusively on board tanks, once in space. However, a major problem remains to be resolved. This type of engine which is already present on the Ariane rocket, cause heating of the air friction to nearly 1000 degrees Celsius. However, for the oxygen reacts with hydrogen, it must be cool. Therefore Reaction Engines is currently working on a technology based on liquid helium, capable of lowering the temperature of over 1000 degrees in less than 0.01 seconds. Paris-New York in 57 minutes Once in service, the A2 could carry passengers at speeds up to 6120 km / h to 9782 km / h. Of incommensurate with those of capacities including Concorde cruising speed was 2,472 mph and would rally Brussels (...) Read more about Gentside.com
