The new advancement in "Engine Technology" may help this plane fly 5x speed of Sound

English aerospace firm Reaction Engines has been at work on an aeroplane it considers would be able to take travellers anyplace in the world in just four hours. If that doesn’t sound absolutely splendid enough, how about this: the aircraft would also be capable of fly in outer space.

Reaction Engines says there’s only a unique truly new technology in the airplane that makes those things promising: “the Precooler”.

In a new video, chief engineer Alan Bond describes that air ingoing the new “Sabre” engine system could be chilled by more than 1,000 degrees Celsius in .01 seconds. That capability would allow a jet engine to run at higher power than what is conceivable today.

More power = more speed. Sufficient to fly at Mach 5, five times the speed of sound, “pretty easily,” Bond states.

The Telegraph clarified the technology in an editorial in late 2012:

The advance technology is a cooling system which uses an array of skinny pipes, organised in a “swirl” pattern and filled with liquid helium, to remove heat from air and cool it to -150C afore it enters the engine. 
In normal conditions, this would cause dampness in the air to freeze, covering the engine with frost, but the company has also advanced a method which stops this from happening.
The company ultimately hopes to use its cooling technology to build a plane that carries 300 passengers and flies like a rocket. It will “transform high-speed aviation,” Bond states, adding, “we have no rivals. We are distinctive.”

The aeroplane itself will measure 276 feet long, and be called the “Skylon”. It would take off and land horizontally (like a airplane), which would make it cooler to reuse than a normal rocket. But in addition to the $US1.1 billion charge for each one, there’s an additional big weakness: The Skylon has no windows, a major disappointment for those enthusiastic to fly in space.

Though to be honest, there’s a drift in the airline industry of risking on getting rid of windows, substituting them with wraparound view screens that could display ever-changing pictures of what’s going on outside aeroplane. So maybe dropping the windows wouldn’t be such a big deal.

The company is presently in the procedure of testing the system. Test flights of the Skylon are scheduled for 2019.
