Washington, Sept 30 : Engineers from Georgia Tech Research Institute have developed a new honeycomb like materials that can reduce aircraft engine noise more effectively than conventional methods.
A honeycomb is a mass of hexagonal wax cells built by honey bees in their nests to contain their larvae and stores of honey and pollen.
The new microchanneled material developed by research engineer Jason Nadler can reduce engine noise by wearing it down through a process called viscous shear.
Viscous shear involves the interaction of a solid with a gas or other fluid. In this case, a gas - sound waves composed of compressed air - contacts a solid, the porous medium, and is weakened by the resulting friction.
