Reaction Engines Ltd

We have achieved a breakthrough in aerospace engine technology by developing ultra-lightweight heat exchangers 100 times lighter than existing technologies that allow the cooling of very hot airstreams from over 1,000 °C to minus 150 °C in less than 1/100th of a second.

This integrated air-breathing and rocket propulsion technology enables the following vehicle applications:

• Mach 5 high altitude cruise:
  • Fly anywhere in the world in 4 hours
  • Efficient sub-sonic and hypersonic cruise modes
• Low-cost reusable space access:
  • Aircraft-like access to space
  • Operates from runway to orbit and back
  • Order of magnitude reduction in cost vs. existing technology
  • 400 x improved reliability
  • Responsive access to space
