The engine, Sabre, is being developed by British scientists and engineers. It is a hybrid between a conventional jet engine, and a rocket system powered by liquid oxygen. The spacecraft, called Skylon, will be reusable like an aeroplane, with no need to jettison expensive fuel tanks during the launch. However, the compression of air at Mach 5 causes superheating, so the engine will need to be cooled using a cryogenic heat exchanger. This engine technology could also dramatically cut the duration of long haul flights between countries and continents. The two engineers also describe their science education and career motivation. This clip is from the BBC series Beneath the Lab Coat. In this BBC series, Rani Price meets young scientists working at the cutting edge of British industry. From cybernetics and fashion, to sport, space exploration and the chemical makeup of suncream, she discovers the huge range of exciting future careers in Science, Technology, Engineering and Maths.

The clip could be used as a stimulus for a research project into the effectiveness of different types of engines and fuels. Students could begin with burning hydrocarbons, then hydrogen before oxygen. They could expand their research to include the forces acting upon the aircraft at different points. "Why is it shaped the way it is when there is no air in space?" would be a thought-provoking question. This clip will be relevant for teaching Physics. This topic appears in OCR, Edexcel, AQA, WJEC KS4/GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 4 and 5 in Scotland. ===================== For more clips from other subjects at the BBC Teach YouTube channel: http://www.youtube.com/bbcteach More from BBC Learning Zone: http://www.bbc.co.uk/learningzone More resources from BBC Bitesize: http://www.bbc.co.uk/education ===================== Subscribe to create your own customised playlists, and get notified about our latest clips.
