This ‘Spaceplane’ could get you from Sydney to London in four hours



There are plans to start running test flights of the ‘hypersonic’ jet in the mid-2020s.

Developers are working on a “hypersonic” jet engine that could see commuters flying from Sydney to London in four hours, and London to New York in one. It’s called a SABRE—that is, Synergetic Air Breathing Rocket Engine—and it allows planes to hit speeds of Mach 5.4 (6400 kilometres per hour). Hence the “hypersonic” moniker: whereas “supersonic” refers to a rate of travel that simply exceeds the speed of sound, “hypersonic” speeds typically exceed it five or six times over.

The hybrid hydrogen-oxygen engine is also way greener and cheaper than current air travel, The Telegraph reports, and will give aircraft the potential to fly in space.

Reaction Pre-cooled Engines could deliver reusable hypersonic planes by 2025


Reaction Engines of the UK could be part of a winning group of bidders for open-ended hypersonic weapons development.

They have proven an innovative pre-cooling system which does not require the development of new materials to handle the heat of hypersonic flight speeds.

The US Air Force Research Labs are already working with them. They would need to partner with US companies like Lockheed or Boeing to get the big military contract.

The pre-coolers are made from thousands of thin-walled tubes to provide high surface area to low weight. Each tube is joined to an inlet and outlet manifold, which allows coolant to be injected and removed for the cooling process. We’re the only people in the world with the heat exchanger manufacturing experience to bond thousands of joints in a single operation, and achieve zero leakage. The joints in our pre-cooler modules are hermetically sealed, meaning that the gas which escapes can be measured by the molecule.
