Hypersonic Space Plane Set to Revolutionize How We Move Through the Cosmos

Reaction Engines announced Monday it will partner with defense multinational BAE Systems in a “working collaboration” to develop its supersonic plane Sabre. BAE purchased 20% of Reaction Engines, providing the strategic investment necessary to accelerate the project, a kind of jet-rocket engine hybrid.

So what can we expect? According to Reaction Engines, driving Sabre is a brand new kind of aerospace engine, which allows for the operation of planes from a standstill on the landing strip, to speeds five times greater than the speed of sound in the atmosphere.

 “[It’s] a new aerospace engine class that combines both jet and rocket technologies with the potential to revolutionize hypersonic flight and the economics of space access,” Reaction Engines’ statement reads.

The main specialty of this engine is its “rocket mode,” which can be used once the Sabre-powered aircraft reaches orbiting altitudes. There, Sabre’s expected to be able to reach speeds up to orbital velocity, or 25 times the speed of sound.

The technology has been subject to extensive independent assessment that has proven its viability, the company noted.

Reaction Engines hopes that BAE Systems’s investment of $31.79 million will be followed by $92.6 million in government grants, Business Insider reported.

Reaction’s cooperation with BAE means it can now access the defense contractor’s “critical industrial, technical and capital resources” while working on supersonic engine, the company said.

Initial tests for Sabre are expected to be carried out by 2019, with hopes that the first planes will  be launched by 2025.

So far, experts are quite optimistic about Sabre’s prospects. David Parker, head of the UK Space Agency, called BAE’s investment "a vote of confidence in the technology," the Financial Times reported.
