Reaction Engines Company Profile

Background

Founded in 1989 by former Rolls-Royce engineers Alan Bond, Richard Varvill, and John Scott-Scott, Reaction Engines Limited (REL) was a British aerospace company headquartered in Culham, Oxfordshire, UK, with a subsidiary in Denver, Colorado, USA. The company was renowned for its pioneering work in air-breathing rocket engine technology, particularly the development of the Synergetic Air-Breathing Rocket Engine (SABRE). REL aimed to revolutionize space access and high-speed flight, striving to make hypersonic travel more efficient and accessible.

Key Strategic Focus

REL's strategic objectives centered on:

• Hypersonic Propulsion and Space Access: Developing the SABRE engine to enable single-stage-to-orbit capabilities and hypersonic flight.

• Thermal Management Solutions: Applying microtube heat exchanger technology across various industries, including aerospace, motorsport, and energy, to enhance performance and sustainability.

• Sustainable Aviation: Collaborating with industry leaders to develop zero-carbon aviation solutions, such as hydrogen-fueled jet engines and fuel cell-powered aircraft.

Financials and Funding

Over its operational years, REL secured significant funding:

• 2015: BAE Systems acquired a 20% stake for £20.6 million.

• 2018: Raised £26.5 million from investors including Boeing HorizonX and Rolls-Royce.

• 2023: Secured £40 million from the UAE's Strategic Development Fund and existing investors.

Despite these investments, REL faced financial challenges. In August 2024, fund managers wrote down the company's valuation from £256 million to £33.8 million due to slower-than-anticipated revenue growth.

Pipeline Development

REL's primary development was the SABRE engine, designed to power the Skylon spaceplane:

• SABRE Engine: A hybrid air-breathing rocket engine intended to enable aircraft to reach orbit without staging. Key milestones included successful precooler tests at Mach 5 conditions in 2019.

• Skylon Spaceplane: A reusable single-stage-to-orbit vehicle designed to carry payloads to low Earth orbit. The project aimed to reduce the cost of space access significantly.

Technological Platform and Innovation

REL's innovations included:

• SABRE Engine: Combining jet and rocket engine technologies, SABRE utilized a precooler to cool incoming air, allowing efficient operation at hypersonic speeds.

• Microtube Heat Exchangers: Advanced thermal management systems applicable across various industries, enhancing performance and efficiency.

Leadership Team

Key executives included:

• Mark Thomas: CEO since 2015, previously with Rolls-Royce.

• Richard Varvill: Chief Designer and co-founder.

• Adam Dissel: President of Reaction Engines Inc., the U.S. subsidiary.

Leadership Changes

In October 2024, REL entered administration due to financial difficulties, leading to significant staff redundancies and operational wind-down.
