Airbus Patent For Hypersonic Passenger Plane That Can Fly At Mach 4.5

Mach 4.5, in case you were wondering, is 4.5 x the speed of sound. For reference, the now defunct Concorde flew at up to Mach 2. BBC News reports on Airbus’s patent for a hypersonic airplane:

Airbus has won a patent for a hypersonic passenger plane which could potentially fly from London to New York in an hour.

Dubbed Concorde 2.0, the jet would be capable of flying more than four times the speed of sound.

Documents lodged with the US Patent Office refer to an “ultra-rapid air vehicle and related method for aerial locomotion”.

So are we on the verge of a revolution in air transport?

How does it work?

According to the documents, the jet would reach speeds as high as Mach 4.5, or four-and-a-half times the speed of sound. That compares to Mach 2 for Concorde.

The patent application says that the aeroplane would use a variety of engines that would serve different purposes and power would come from hydrogen stored onboard.

US Military Tests X-51A, Capable of Speeds up to 4,500 MPH

Reverse-engineered alien technology or human ingenuity? Probably the latter. It seems the US Military is testing a new aircraft that can reach up to Mach 6. It’s first test flight will be tomorrow. From the DailyMail:

It may look like a vehicle the Thunderbirds would travel in, but in fact this experimental aircraft could be the future of long haul flights.

It uses a revolutionary ‘scramjet’ engine that allows it to travel at hypersonic speeds.

Tomorrow, it will be dropped from a B52 bomber in its latest test.

The craft, called the X-51A Waverider, is currently being prepared at Edwards Air Force Base in the Mojave Desert.

Tomorrow, it will take part in a key test.

Attached to a B-52 bomber’s wing, it will be taken from Edwards to about 50,000 feet over the Pacific Ocean near Point Mugu.
