Boeing and Safran successfully completed flight tests of passive noise reduction fairings developed by Safran as part of the latest phase of its long-running ecoDemonstrator program. The experimental fairings, which were fitted to the landing gear of the Etihad 787-10, are designed to reduce noise-generating turbulent flow around the drag and side braces of the main landing gear, and steering mechanism and tow fitting of the nose leg. As engines become quieter with each new generation the airframe is becoming a proportionately bigger contributor to community noise around airports.
