Landing gear noise control using perforated fairings

Landing gears of commercial aircraft make an important contribution to total aircraft noise in the approach configuration.Using fairings to shield components from high speed impingement reduces noise.Furthermore,perforating these fairings has been confirmed by flight tests to further enable noise reduction.Following an earlier fundamental study of the application of perforated fairings,a study has been performed to investigate and optimize the benefits of bleeding air through landing gear fairings.By means ...
