NASA tested noise reduction technology for civil aircraft

NASA's X-59 passenger supersonic aircraft was designed to fly at 1,700 km / h, nearly 1.4 times the speed of sound.

The US Aeronautics and Aeronautics Agency (NASA) is planning to test noise reduction technology for new generation civil aircraft called QueSST X-59 this month, Express Digest reported yesterday. NASA spokesperson Sasha Ellis said the upcoming test will focus on addressing noise-related challenges, which are the drawbacks of previous supersonic models.

The X-59 was designed to fly passengers at 1,700 km / h (nearly 1.4 times the speed of sound) and reach a range of 16.8 km above the ground. At this rate, the plane only takes 3 hours to fly from London to New York.

The new noise reduction technology is expected to help the X-59 fly past the speed of sound with a sound pressure level of only 60 dBA, much lower than other supersonic models like Concorde. In addition, the aircraft is also designed to prevent "supersonic explosions" - the phenomenon of shock waves being activated and detonated when objects move faster than the sound hitting the air.

To assess the noise reduction capability, NASA will use a sensor system to measure noise from the ground below, and consider the community's response through a survey of over 500 people selected. Under the plan, the first passenger flight of the X-59 will be launched in 2021.
