  • Q8
    What is the purpose of the combustor in a turbofan engine?
    To generate electricity for the aircraft's electrical systems
    To burn fuel and mix it with compressed air to produce hot, expanding gases
    To minimize turbulence and improve air flow
    To filter incoming air and trap debris
    30s
  • Q9
    How does a turbofan engine produce thrust?
    By pushing air through a series of ducts and channels
    By expelling a high-velocity stream of hot gases out of the rear of the engine
    By creating a low-pressure area in front of the engine
    By harnessing the power of magnetic fields
