BTEC First Engineering Learning aim B Know about developments in engineering materials and technologies Learning aim B is concerned with modern materials and processes. 1

Match the key terms with the definition Telematics Blended wing bodies Surface nanotechnology Optical fibres Bionics Hydrogen fuel cells Replaced copper wire. Much faster speeds, with greater bandwidth. Much more information can be transmitted along the same size of cable. The energy produced is clean, with only heat and water as waste products. Engines that use hydrogen fuel cells are quieter and more simple than petrol or diesel engines. Different chemicals can be used on materials to give them differing surface properties. One good example is self-cleaning windows. Similar to satellite navigation systems, a telematics system can be used to track locations of vehicles by using GPS references and ICT systems combined. Different from ‘flying wing’ designs. These aircraft have a distinct wing and body, although much more aerodynamic than existing designs. Small electronic devices can be used for medical purposes to improve the medical condition of individuals. A pacemaker fitted to regulate a person’s heartbeat is a good example.

Learning objectives: - Bigger picture: - Know about new technologies used in engineering (UNIT 1 EXAM in January 25%) Learning objectives: - Be able to explain what is meant by the term new technology Describe a range of different new technologies used in engineering Explain advantages and disadvantages of a range of new technologies Success criteria: - Provide a description of different new technologies and how they work Correctly explain the advantages/disadvantages of a range of new technology

Often used in the communications sector, have replaced copper wires. BTEC First Engineering New technologies Optical fibres Telematics Often used in the communications sector, have replaced copper wires. Combines ICT with communications technology to allow vehicles to be tracked. Hydrogen fuel cells Blended wing bodies Chemical energy in hydrogen is converted to electricity. Now an alternative to petrol engines. Advanced aircraft designs consisting of large aerofoil wings joined to an aircraft body. Surface nanotechnology Bionics Teacher notes (PS 8): Optical fibres – replaced copper wire. Much faster speeds, with greater bandwidth. Much more information can be transmitted along the same size of cable. Hydrogen fuel cells – the energy produced is clean, with only heat and water as waste products. Engines that use hydrogen fuel cells are quieter and more simple than petrol or diesel engines. Surface nanotechnology – different chemicals can be used on materials to give them differing surface properties. One good example is self-cleaning windows. Telematics – similar to satellite navigation systems, a telematics system can be used to track locations of vehicles by using GPS references and ICT systems combined. Blended wing bodies – different from ‘flying wing’ designs. These aircraft have a distinct wing and body, although much more aerodynamic than existing designs. Bionics – small electronic devices can be used for medical purposes to improve the medical condition of individuals. A pacemaker fitted to regulate a person’s heartbeat is a good example. Chemical coatings are applied to the surface of materials to improve their properties.

New technologies Surface Nanotechnologies The nanotechnology treatment encourages the water to form droplets on the surface which just run off Useful because it saves us needing to clean tall buildings, improves water resistant clothing https://www.youtube.com/watch?v=XZVH7CASrBk

Surface nanotechnologies: Ceramics – produces hygienic surfaces Metals – resistant to corrosion Glass – cleaning processes is much less time consuming Plastics – easier surface cleaning Textiles – surface becomes water and dirt repellent Minerals – longer lasting materials
