Wired Up for Sound, NASA Rides with Boeing 787
NASA worked with Boeing to wire more than 200 microphones to the outside skin of this 787-10 Dreamliner on loan from Etihad Airways – equipment that was used as part of a NASA study to hear how total aircraft noise is affected by the placement and interaction of the jet engines with the airframe. Wires from the microphones were snaked through two passenger windows, seen here covered in duct tape, and connected to several pallets of recorders inside. The experiment was one of several flown on the 787 – seen in flight in the inset image – during Boeing’s ecoDemonstrator program during late August and early September. NASA researchers will use the information recorded during multiple flights to help design future airliners that are quieter. Text Credit: Jim Banke, Aeronautics Research Mission Directorate
