Supersonic plane on hydrogen

The plane reduces the noise of the sonic boom — a loud bang caused by shockwaves created by an object moving faster than the speed of sound.
“This noise has been the main limit, if not the only one, preventing the opening of lines other than transatlantic ones for the Concorde aircraft,” the patent says.
The plane does that by being “near-vertical,” like a rocket, while ramping up to supersonic speed and its cruising altitude of 30,000 to 35,000 meters — 20 kilometers higher than conventional commercial aircraft.

Airbus has received a patent for a design of a supersonic passenger plane on hydrogen. Thanks to ultra-modern engines, the airplane can achieve speeds over 5,500 mph.

The granted patent discloses an apparatus which is provided with delta-shaped wings, provided with three different types of engines:

  1. turbojets for taxiing, takeoff and landing
  2. a rocket motor for rapid acceleration
  3. ramjets for high-altitude cruising

The plane will be fueled by hydrogen and liquid oxygen. Read More
