Plasma Reduces Jet Noise (Turbines?)
Here's an article:
http://www.newscientist.com/news/news.jsp?id=ns99996073 So if plasma reduces jet noise, then can it reduce turbine noise? There are gyroplanes like the one made by Groen Bros, and also the old Fairy, which used ramjets on the rotortips to boost rpm and lift during takeoff, but this caused terrible noise problems. Could this plasma noise-deadening approach make the ramjet rotor-assist more practical and feasible? |
