Airbus acquired a patent that would be envied by F4. If there is a field in 21 century that is considered technologically advanced, it is ultrasonic passenger flights. After Concorde's withdrawal of 2003, the sound velocity returned to a military monopoly. 
But technicians Marco Prampolini and Yohann Coraboeuf of Airbus managed to obtain a patent for a "very fast air vehicle" designed to fly 20 kilometers above any conventional aircraft and at speeds over four times its speed. that is, twice the speed of the Concorde.
The Concorde could cross the Atlantic in less than three hours, but only 20 was built from an Anglo-French development program in the 1960 decade according to Business Insider.
But the combination of unbelievable noise, the US FAA's restrictive regulations, and the Arab embargo on oil in the 1970 decade has made Concorde economically unprofitable.
The Airbus patent takes the Concorde concept, increases efficiency and reduces noise pollution. According to Airbus, the craft will essentially be a flying tanker with most of the fuselage consisting of liquid oxygen and with environmentally friendly liquid hydrogen. The passenger cabin will be for 24 people, and the cockpit will be located in the bow.
But what really determines Airbus's design and makes it stand out is the propulsion systems used to keep up.
In a standard flight, will be able to take off like a conventional airplane using conventional turboprops, but once in the air, opening a rear hatch will reveal a rocket engine, which will send the aircraft into a near-vertical orbit, accelerating to supersonic speeds.
As the airplane approaches one Mach, the turbines will close and retract within the spindle. Upon completion of the acceleration phase the airplane will fly at speeds ranging from 4 to 4,5 Mach at 30.000 to 35.000 m.
According to his specifications, he could carry two or three tons of cargo, which is equivalent to 24 passengers and their luggage.
It is extremely unlikely to see supersonic airbus flights with cheap tickets, if ever built. Perhaps if the company decides to build it to use it only for VIP passengers. Alternatively, the vessel could also have military application, since its speeds and technology would be envied even by warships.
