Boeing and Rolls-Royce have invested £26.5 million (approx. $37.6 million) in Reaction Engines Limited, a UK-based aerospace company working on the 3D printing enabled SABRE engine, capable of Mach 25.
Reaction Engines Chief Executive Mark Thomas comments, “In addition to providing our largest round of private investment, these new partners bring invaluable expertise in both hypersonics and engine technologies with significant access to target markets,”
Reaction Engines was formed in 1989 “to design and develop the technologies needed for a new class of innovative hypersonic propulsion system,” i.e. the SABRE. Steve Nordlund, Vice President of Boeing investment arm HorizonX comments, “We continue to connect capabilities around the globe with our investment in Reaction Engines, which is our first in a UK-based company. We expect to leverage their revolutionary technology to support Boeing's pursuit of hypersonic flight.”
The SABRE is a hybrid engine capable of flying at both low and high altitudes, using hydrogen/oxygen mixing (low altitude), or stored Liquid OXygen (LOX) when launched into space. With the latest fund from Boeing and Rolls-Royce, Reaction Engines has raised over £100 million ($142 million) in the past three years.
