Supersonic plane on hydrogen
The granted patent discloses an apparatus which is provided with delta-shaped wings, provided with three different types of engines:
- turbojets for taxiing, takeoff and landing
- a rocket motor for rapid acceleration
- ramjets for high-altitude cruising
The plane will be fueled by hydrogen and liquid oxygen.
Like a helicopter to 30 km altitude
The patent describes that the plane takes off vertically to a height of approximately 30 kilometers. This way of rising has been chosen to avoid the ‘bang’ – produced breaking the speed of sound – will be heard on the ground. By going vertical, it runs smoothly through the sound barrier. Also, the streamline of the jet is adjusted to reduce ‘the bang’.
Once at cruising altitude, this supersonic plane switches to the turbojets. These jets (at the ends of the wings) will bring the jet to a cruising speed of 4.5 times the speed of sound.
According to Airbus, the jets and turbo will use hydrogen as a fuel. It’s unclear how much hydrogen can be taken along and for what distances are.
The new turbo jet can carry 20 passengers. Airbus said the plane would be targeted mainly at business travel and VIP passengers “who require transcontinental return journeys within one day,” and at the military.
2.5 times faster than the Concorde
This plane is super sonic fast. London – New York takes one hour! The old Concorde needed 3.5 hours for it.
