NASA will Publicly Test Aircraft with Quiet Supersonic Tech This November

NASA Armstrong Flight Research Center test pilot Jim "Clue" closes at least his F/A-18's ports after reaching 49,000 feet from the trial site because he is higher than where normal airlines fly, he is in Mach 1, with the speed of sound or approximately 630 miles per hour at that height.This nearly all the airplanes have been taken to reach this peak in the sky, but it will not last long.

NASA has announced of testing "quiet" supersonic flights over Texas that could revolutionise air travel.

Some background: Supersonic travel over land has been banned in the U.S. since 1973, owing to the huge noise produced when a plane breaks the sound barrier.

When traveling at supersonic speeds, those faster than the speed of sound in air, these air molecules are pushed aside with such considerable force that the individual pressure waves merge and form a shockwave.

To test the feasibility of bringing supersonic travel back, NASA will enlist the help of an F/A-18 aircraft to dive in the skies above Galveston, producing both traditional sonic booms and also simulating the quieter booms that NASA hopes to achieve with its experimental X-59 jet.

NASA's team leader for sonic boom community response research at Langley, Alexandra Loubeau, said, "We never know what everyone has heard".

An initial test of the research methodology using the F/A-18 was conducted in 2011 with the help of the United States military community that lives on base at Edwards Air Force Base in California.

"With the X-59 you're still going to have multiple shockwaves because of the wings on the aircraft that create lift and the volume of the plane". However, you won't be seeing the X-59 to fly anytime soon. The tests will aim to determine just how loud NASA's new "quiet" supersonic technology really is, and compare it to the sounds of a traditional sonic boom.

The X-59 is scheduled for delivery by the end of 2021. NASA isn't planning to do community overflights with the QueSST until 2023, the agency said.

"For everyone working on this important project, this is great news and we're thrilled with the designation", Jaiwon Shin, associate administrator for NASA's Aeronautics Research Mission Directorate, said in the NASA statement. "While construction continues on the X-59, we can use the diving maneuver to generate quiet sonic thumps over a specific area".

To see the F/A-18 in action, watch the above NASA video from a flight at the Armstrong Flight Research Center.

You'd only hear the sonic boom when the shockwaves reach your tiny little ears.
