NASA Reveals 925mph Concorde Son ‘Silently’ Breaks Sound Barrier Before Flight 2022
NASA has released a time-lapse video of construction work on a new experimental supersonic jet dubbed “Son of Concorde.”
The 40-second clip shows the manufacture of the X-59 Quiet SuperSonic Technology, or QueSST, aircraft from May 2019 through June 2021.

Aerospace giant Lockheed Martin performs work at a facility in Palmdale, California. NASA says it is on track to begin flight tests in 2022.
When completed, the X-59 will sail at Mach 1.4, which is 925 mph and faster than the speed of sound (767 mph).
His party thing is that his sonic boom shouldn’t sound louder than the thud of a car door closing at ground level.
This means the jet can fly without producing a surprising boom for the people below, a problem suffered by Concorde, which was retired in 2003.
Before any flight can take place, Lockheed engineers and technicians work to merge the main sections of the plane.
The time lapse released on Tuesday shows the nascent vehicle resembling an actual aircraft for the first time since construction began in 2018.
âWe have now gone from a set of separate parts spread across different parts of the production floor to an airplane,â NASA engineer Jay Brandon said.
The aircraft is assembled using features on the structure that allow engineers to precisely align its components.
These include the aircraft wing, tail, and fuselage or front section, all three connected in the video.
Laser projections are then used to ensure that each part has been fitted with precision.
It all fits together a bit like Lego bricks, according to David Richardson of Lockheed Martin.
âExtensive use of features and full-size pre-drilled mounting holes has dramatically reduced the time it takes to locate and install parts, especially to assemble large assemblies like this,â he said. .
“It’s kind of like how the Legos go together. We used the laser tracker to make sure everything is aligned to spec before we bolted everything permanently.”
Silent like a mouse
NASA has given the green light to the project which will be built by Lockheed Martin in 2019. The cost of the program is $ 247.5 million (Â£ 189.7 million).
When fully built, the X-59 is expected to be 94 feet long with a wingspan of 29.5 feet.
It will have a maximum takeoff weight of 32,300 lbs and will fly at an altitude of 55,000 feet.
The craft will be powered by a single General Electric F414 engine and will sport a 4K camera up front for increased visibility.
The goal is to create an aircraft capable of flying at a speed of Mach 1.42, with a sonic boom a thousand times quieter than previous supersonic planes.
The barrier for supersonic flight is 768 mph – a speed known as Mach 1.
When flying at high speed, sound waves cannot spread quickly enough and thus create an audio âwake-upâ.
It’s called a sonic boom, and it’s a loud, annoying sign that a supersonic plane is flying overhead.
The “perceived” sound of a Concorde was 110dB, which is thousands of times louder than the expected noise level of the X-59.
Air experts hope the shape of the X-59 will maximize its sonic boom between 60dB and 75dB for people on the ground.
If successful, the NASA design could be deployed for commercial flights – or maybe even the US military.
