Learn about plasma actuators NOW!

Jet engines may run quieter in the future, with technology developed at Ohio State University.

Researchers here have developed a silencer technology that creates electrical arcs to control turbulence in engine exhaust airflow - the chief cause of engine noise. The university has applied for a patent on the design.

With the flip of a switch, pilots could turn the silencers - called plasma actuators - on and off, reducing noise around commercial airports or military airstrips, said Mohammad Samimy, professor of mechanical engineering.
