How Quiet Can Researchers Make Future Drones?
Army researchers are looking at how to make future unmanned aircraft systems stealthier. Current rotors are noisy. U.S. Army CCDC Army Research Laboratory aerospace engineer Dr. Matthew Floros is investigating a potential technology solution to decrease the sound of certain rotor blades by as much as 10 decibels. That's a lot quieter. Listen to the conversation about what we learned today!
