Breakthrough for spaceplane that will rocket from London to New York in under an hour as British firm Reaction Engines confirms key test success

A ‘SPACEPLANE’ that flies 25 times faster than the speed of light has successfully passed a crucial testing milestone.

The hypersonic plane is so fast it could jet from London to New York in less than 60 minutes and transport you from the UK to Australia in four hours.

Oxford-based Reaction Engines has been working with the European Space Agency and the UK Space Agency, along with BAE Systems, to make the powerful aircraft.

Reaction Engines has recently been testing a ‘pre-cooler’ for the plane, which is technology that would allow it to travel faster than ever before.

The pre-cooler is critical in the planes development because it is required to stop the engine from melting by lowering the temperature of compressed air in the engine from more than 1,000°C to room temperature in one twentieth of a second.

Thousands of tubes inside the pre-cooler, which are thinner than human hair, contain liquid helium that can cool the air as it rushes past them.

The aircraft travels at 25 times the speed of light

Until now, heat has been a limiting factor for how fast aircraft can travel, including Concorde which travelled at two times the speed of light.

This technology could now be combined with the spaceplane’s experimental engine, referred to as Sabre.

Sabre is intended to be much lighter than a conventional rocket engine because it would carry less fuel oxidant.

It is being designed to draw oxygen into the engine to use for combustion from take off until it reaches just over 4,000mph.

After this point, the engine would need to burn liquid oxygen and liquid hydrogen from on-board fuel tanks.

The spaceplane would need to continue using this process until it reached 25 times the speed of sound to enter space.

The company ultimately aims to create a reusable vehicle that has the fuel efficiency of a jet engine with the power of a rocket.

Plans for the hypersonic plane don’t just include getting people around the world in a fraction of the time but also taking people or cargo into Space and back for just a fraction of the current cost.
