    • ‘They have also ordered two versions of Predator B with turbofan jet engines.’
    • ‘He pushed his throttle all the way forward and kicked the afterburning engines of the four large turbofans into action.’
    • ‘Its easy forgeability and strength at moderate temperature has led to extensive use as compressor blades and discs in gas-turbine engines and as fan blades in the most recent turbofan engines.’
    • ‘Such turbine engines are also called jet engines and they embrace a family of products: turbojets, turbofans, and turboprops.’
    • ‘Thrust is coming from two components in the turbofan.’
    • ‘The swing-wing design and turbofan engines not only provide greater range and high speed at low levels but they also enhance the bomber's survivability.’
    1. 1.1An aircraft powered by a turbofan.
      • ‘The F - 117A is powered by two turbofan engines from General Electric.’
      • ‘The Hawk 200 is powered by an Adour 871 twin-spool, low bypass ratio turbofan engine from Rolls-Royce.’
      • ‘You can see that the core of a turbofan is a normal gas turbine engine like the one described in the previous section.’
