NASA Tech Cuts Airframe Noise by 70% on GIII Testbed
Acoustic Research Measurement (ARM) flights tested technologies such as landing gear fairings and the FlexSys morphing-wing flap
NASA's Acoustic Research Measurement (ARM) flights tested technologies such as landing gear fairings and the FlexSys morphing-wing flap on a Gulfstream GIII testbed. Using an 185-sensor microphone array deployed on the Rogers Dry Lake at Edwards Air Force Base in California, the agency found that airframe noise can be reduced by more than 70 percent on landing approach using these non-propulsive technologies.
