Not too long ago, a staff from NASA and the Japanese Aerospace Exploration Company (JAXA) examined a mannequin of the X-59 experimental plane.
What’s it?
The X-59 plane measures round 99.7 ft (30.4 meters) lengthy, with a wingspan of 29.7 ft (9 meters). With the wind tunnel on the JAXA analysis facility solely measuring round three ft (or a meter) throughout, the researchers realized they must take a look at the plane utilizing a a lot smaller mannequin.
They scaled down the X-59 to 1.62% of its precise measurement, round 19 inches from entrance to again. Then they uncovered the mannequin to supersonic wind speeds of roughly 925 miles per hour (or 1,488 km per hour) also referred to as a cruising velocity of Mach 1.4.
The place is it?
The wind tunnel is at a JAXA analysis facility in Chofu, Japan.
Why is it wonderful?
The X-59, with its stretched noise and ultrathin wings, is designed to diffuse the supersonic shock waves created when the plane travels quicker than the velocity of sound. So as a substitute of a loud sonic growth, the airplane ought to create extra of a “thump” noise.
Utilizing a mannequin, the researchers might acquire key details about how air flows over and across the plane, permitting them to enhance its design even additional to cut back its noise. This take a look at was the third of a sequence of wind tunnel assessments, giving specialists insights into the noise the plane makes when flying at excessive speeds.
The X-59 itself was constructed by Lockheed Martin Skunk Works in California and is slated to make its first historic flight someday this 12 months.
