FEATURE - NASA testet 30 Meilen langes Mikrofon als Vorbereitung für leise Überschallflugzeuge des Typs X-59
PICTURE SHOWS: Juliet Page, a physical scientist with the Volpe National Transportation Systems Center, calibrates a microphone station during the CarpetDIEM flight series. The array featured high-fidelity microphones arranged in several configurations, giving researchers the ability to obtain accurate sound data and assess the loudness of the sonic booms, just as they will measure the quiet sonic thumps from the X-59.

STORY COPY:
(29 Aug 2019) NASA has successfully tested a large microphone array in California’s Mojave Desert as part of a flight series in preparation for the agency’s quiet supersonic X-plane, the X-59.
Flying at speeds faster than Mach 1, the speed of sound, typically produces a loud sonic boom heard on the ground below. NASA’s X-59 Quiet SuperSonic Technology X-plane, or X-59 QueSST for short, will fly over select communities around the U.S. to demonstrate the ability to reduce that sonic boom to a quiet thump. The data from these flights will be turned over to the Federal Aviation Administration to possibly establish new sound-based rules for supersonic flight over land. This could open the door to future faster-than-sound commercial cargo and passenger air travel.
Before these community overflights take place, however, the X-59 will first undergo an acoustic validation phase, during which NASA will deploy an approximately 30-mile-long array of specially-configured microphones to measure the X-59’s thumps, to verify that they are as quiet as predicted.
The recently-completed Carpet Determination In Entirety Measurements flight series, or CarpetDIEM, was NASA’s “first practice” for the X-59’s acoustic validation flights.
“The X-59 is designed to have quiet sonic booms that won’t be disturbing to the people, but first we actually have to go out and prove it,” explained Ed Haering, NASA’s principal investigator for CarpetDIEM. “NASA will do that by flying the aircraft and taking real measurements on the g

FEATURE - NASA testet 30 Meilen langes Mikrofon als Vorbereitung für leise Überschallflugzeuge des Typs X-59
PICTURE SHOWS: One of multiple microphone stations used in the CarpetDIEM flight series, which gave researchers valuable lessons learned in preparations to deploy a similar array for the quiet supersonic X-59. Prior to community overflights, X-59 will undergo an acoustic validation phase, during which NASA will deploy the array of specially-configured microphones to measure the X-59’s thumps, in order to verify that they are as quiet as predicted.
