NASA Technologies Significantly Reduce Aircraft Noise

The ARM flights were flown on NASA’s SubsoniC Research Aircraft Testbed G-III aircraft, or SCRAT, at NASA’s Armstrong Flight Research Center in California. NASA combined three technologies, including Landing Gear Noise Reduction, landing gear cavity treatments, and the Adaptive Compliant Trailing Edge flexible wing flap, to demonstrate a reduction in airframe noise in excess of 70 percent. This may reduce aircraft noise for communities that live near airports. Continue reading: https://www.nasa.gov/press-release/nasa-technologies-significantly-reduce-aircraft-noise
