UK Government invests £60m in Skylon plane that can fly from London to Sydney in 4 hours

Full ground-based engine test is planned for 2020.

This is the new super-plane. Why is it in the news?

The UK government has pumped £60m into a next-generation engine that will apparently make low-cost space travel possible for commercial customers.


Really? Will we be exploring the final frontier by Christmas?

Not quite. The new ‘Sabre’ engine - a hybrid rocket and jet propulsion system which theoretically allows travel anywhere on Earth in four hours or less - is still at least a decade away. However a full ground-based engine test is planned for 2020.


Who’s making it?

A company called Reaction Engines - which is based at Culham Science Centre in Oxfordshire - has been given a £60m grant by the government to help it develop and build the Skylon super-plane. The cash will also be used to help change the company from being mainly research-based to testing and eventual commercial applications.


Anyone else excited about it?

Aerospace giant BAE is snapping up 20 per cent of the company for £20.6m. BAE and Reaction will form a “working partnership... to progress towards the demonstration of a ground based engine”.


What’s the science behind it?

The super-plane will rely on cooling an incoming airstream from 1,000 degrees C to minus 150 C almost instantly, at close to 1/100th of a second. It will double the technical limits of a jet engine, and allow the craft to reach, up to five times the speed of sound, before switching to a rocket engine to reach orbit.


Anyone excited?

Blimey, on that basis we could get to our annual destination of Ibiza before our plane took off ;) :D

Interesting engine, but very complicated. It uses liquid hydrogen for much of the cooling, with a helium loop for heat exchange as well. There are a series of cryogenic (-200 F temperature or below) pumps and turbines in each engine (some hydrogen, some helium, which is very hard to keep in a system). This engine has quite a few more potential failure points that a 'normal' jet engine, so 'getting it right' will be a significant challenge.
