New U.S. Navy Anechoic Chamber Tests Two Aircraft Together

摘要

The largest anechoic chamber on the U.S. East Coast—a crucial tool for fine-tuning stealth designs and electronic warfare tactics—opened here last week and already has a full slate of commercial and military customers through the end of the year. The interior of the $49-million, 180 X 180 X 60-ft. chamber is insulated from all outside electronic signals. It is covered by polyurethane foam pyramids impregnated with carbon that absorb electronic signals created within the chamber. By eliminating all exterior noise and interior echoes, researchers can precisely calculate the output and effects of electronic devices.
