Skylon

Reaction Engines's Synergetic Air-Breathing Rocket Engine (SABRE) engine has passed a major milestone, as a key component handled conditions equivalent to an airspeed of Mach 5 (3,704 mph, 5,961 km/h).

Reaction Engines' Synergistic Air-Breathing Rocket Engine (SABRE) has the potential to be an aeronautical game-changer by providing single-stage-to-orbit launch capabilities. Construction has now begun on the facility that will be used to conduct the ground test of SABRE's engine cycle.

Reaction Engines' Skylon reusable spaceplane project has been given a boost ,with analysis by the United States Air Force Research Laboratory (AFRL) confirming the feasibility of the SABRE engine cycle concept that lies at its heart.

The British government announced on Tuesday that it has authorized an investment of £60 million in Reaction Engine Ltd’s Skylon spaceplane after a successful feasibility test managed by the European Space Agency.

Reaction Engines Ltd. announced on Wednesday the completion of a critical round of testing of its SABRE engine’s precooler system.

Reaction Engines has announced that is has successfully tested the key pre-cooler component of its revolutionary SABRE engine crucial to the development of its SKYLON spaceplane.

A technical review of the Skylon, an unpiloted, single-stage, reusable spaceplane, carried out by the European Space Agency (ESA) concluded there are "no impediments" that would prevent the continued development of the Skylon and its SABRE engine.
