Aircraft manufacturer Airbus has filed a patent assigned to an aircraft a speed of mach 4.5. The plane would have three different types of engines have to use that speed to achieve and can take off vertically.
The patent was to Airbus assigned by the American USPTO, reports the International Business Times. The plane would be using jet engines vertically to take off and to accelerate. The turbojets blows at a given point and the plane using a rocket engine to an altitude of 30 kilometers would have to rise. At that height, take two ramjets it over so that the aircraft a speed of mach 4.5 should be able to achieve, about 5500 kilometers per hour, which allows the unit almost hypersonisch.
According to Airbus, there would be about 20 people in the plane should fit, which would be in about an hour from London to New York can fly. The aircraft described in the patent will probably not go fast, to fly, to date, the development of (almost-)hypersonic aircraft is very difficult proved.
