NASA will test "silent" supersonic flights in Texas

Formerly called "Low-Flight Flight Demonstrator", the project was renamed X-59 QueSST. [19659003] TEXAS – NASA's mission to create a silent supersonic aircraft that could revolutionize air travel has taken a step closer with Texas test plans.

The Space Agency announced that she was going to publicly demonstrate her technology near Galveston. Make sure his prototype will really barely audible when he cross the wall of sound.

The creation of a supersonic aircraft that does not produce sonic booms could change the game for aviation. Before being decommissioned, Concorde's speed was limited on some land routes because of disruptive sound waves.

If NASA's experimental project – formerly known as the X-plane or "Low-Flight Flight Demonstrator" QueSST – works, it should help make supersonic flying more economical.

Starting in November, NASA will use supersonic F / A-18 Hornet jets on Galveston to mimic the sound profile of the X-59 while a group of about 500 residents document noise levels – If there are any …

When performing dives at the speed of sound, the jets will produce two types of sonic booms to really determine the sound they produce on the ground.

According to NASA, Galveston was chosen as the test area because it is located near the Gulf of Mexico, allowing fighter planes to keep stronger booms at sea, while launching "deaf blows" quieter in the city.

$ 247.5 million contract for the highly anticipated aircraft construction

Ability to reduce noise

The secret of the aircraft's noise reduction capability is its unique shape structure, designed for supersonic waves to be transformed Booms

"With the X-59, you will still have multiple shockwaves because of the wings of the aircraft that create lift and volume of the plane, "says Ed Haering, aerospace engineer at NASA's Armstrong Flight Research. Center. "But the shape of the aircraft is carefully adjusted so that these shock waves do not combine." Instead of getting a strong boom-boom, you're going to have at least two dull noises, if you even hear them at

"That's why the F / A-18 is so important to us in As the tool continues, while the construction continues on the X-59, we can use this dive maneuver to generate quiet dull shots on a specific area. "

Concorde Successor?

The X-59 is scheduled for delivery by the end of 2021. Once the aircraft has finally been built and its noise ratings established, NASA says it will perform Test flights over other cities in the United States and will bring together ground intelligence.

The noise problem has stubbornly invented aeronautical innovators the Anglo-French Concorde project since the retirement of the aircraft in 2003.

Several attempts to revive supersonic air transport are underway

Japan Airlines has invested $ 10 million in Boom Technologies, a Denver-based start-up that also hopes to revive

Meanwhile, Spike Aerospace hopes to test its supersonic Jet S-512 by the end of 2018. [19659020] [ad_2]
