While many low altitude unmanned aerial vehicles are able to frustrate visual, radar and infrared detection, the noise they emit especially as they hone in on targets can give them away.
Engineers and technicians at Georgia Tech Research Institute are seeking ways to reduce the acoustic signature of these UAVs without disrupting on board sensors. Rick Gaeta, an aeroacoustics specialist, says work so far has allowed “us to separate acoustics issues into their component parts, and that in turn helps us to attack these problems.”
Next on the agenda is applying the findings on a prototype for testing.
He believes the GTRI team is well on the way to developing a truly covert aerial platform.
