Safran completes quieter demo

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. (Source: Aviation  Week 09/23/20) Gulf Coast Note: Since 2006, Safran Helicopter Engines powers the Army's Light Utility Helicopter UH72-A Lakota twin-engine with its Arriel 1E2. Gulf Coast Note: Those Lakota helicopters are built in Columbus, Miss. https://aviationweek.com/air-transport/aircraft-propulsion/ecodemonstrator-completes-quieter-787-landing-gear-tests
