Low frequency liners for turbofan engines

  title={Low frequency liners for turbofan engines},
  author={Rie Sugimoto and Jeremy Astley and Paul Murray},
Reducing aircraft noise is critical to the growth of air transport and for quality of people’s life. The aircraft noise is composed of contributions from various source mechanisms and fan noise is one of the dominant components at take-off and landing for aircraft with modern high bypass ratio turbofan engines. Fan noise is generated at the fan, propagates through engine intake and bypass duct and is radiated to the outside. Acoustic liners are applied on the internal walls to attenuate the fan… CONTINUE READING
