Airframe Noise Sources and Reduction Technologies in Aircraft

The continuous increase of the air traffic linked to the operations around airports leads to increase the community noise problem. Aircraft noise is an issue of enormous environmental and technological impact. Projected growth in significant quieting of modern jet engine has brought renewed attention to the nonpropulsive component of aircraft noise. Airframe-generated noise can be the dominant component of the total noise radiated from commercial aircraft, particularly for large aircraft and especially during the landing approach. In this paper, a review of major components of airframe noise and technologies with the greatest potential to reduce airframe noise are presented.
