D

Question 3 Explanation: 

Reaction Engines Limited (REL), the UK company developing a revolutionary aerospace engine, recently announced investments from both Boeing and Rolls-Royce.

  • REL is working on a propulsion system that is part jet engine, part rocket engine. The company believes it will transform the space launch market and usher in hypersonic travel around the Earth.
  • 'Hypersonic' refers to speeds of more than five times the speed of sound (Mach 5).
  • REL is developing what it calls the Sabre engine. This power plant is designed to push a vehicle from a standing start all the way to orbit in a single step.
  • It would work like a conventional jet engine up to about Mach 5.5 before then transitioning to a rocket mode for the rest of the ascent.
  • Key technologies include a compact pre-cooler heat-exchanger that can take an incoming airstream at a temperature of over 1,000C and cool it to -150C in less than 1/100th of a second. This would permit Sabre to use oxygen direct from the atmosphere for combustion instead of carrying it in a tank with the weight penalty that implies.
