NASA will begin next month's supersonic tests for its next-generation passenger plane, named Son Concorde & # 39; by aviation aficionados.
The airplane, officially known as the X-59 Quiet Supersonic Transport (QueSST), will release a "silent" boom when it launches test flights on November 5th.
The first flight X-59, which could one day fly from London to New York in just three hours, not to announce a loud boom, is scheduled for 2021.
The aircraft could become the first commercial aircraft to carry passengers, as the Concorde English-French jet icon was abolished 15 years ago.
In the aftermath, the space agency will use a modified combat jet to check the "acoustic signature & # 39; the engine that will be used on the plane, sending it to a series of dives.
He recruited 500 people on the field to respond in response to the noise surveys created by the F / A-18 Hornet to ensure that the flight flies while he is tormenting over Texas.
Before the plane gets into the sky, NASA is investigating whether members of the public reject the noise produced by the X-59 when it breaks the sound barrier.
Tests scheduled for November will see how the F-18 fighter plane dives diving maneuvers off the coast of Galveston, Texas, near Houston.
The plane will drop quickly from nearly 50,000 feet (15,200 meters), will briefly fire and fire the sound that is likely to come from the X-59 aircraft.
The noise, which NASA calls "acoustic impact", should sound more like the doors that fall into the car, unlike the boom produced by the existing supersonic aircraft.
The agency will measure sounds using field sensors while collecting public reactions through a series of surveys.
Sasha Ellis, a NASA spokeswoman for the X-59 mission, told Newsweek: "We're just focusing on solving the challenges of silent supersonic flights over the earth, reducing the sound boom to an acoustic stroke."
Alexandra Loubeau, a member of NASA's Sonic Boom communications response team in Langley, said in July: "We will never know exactly what everyone has heard.
"We will not have the beats on their shoulders in their home.
"But we would at least have an estimate of the range of noise levels they actually heard."
The X-59, which NASA develops with Lockheed Martin's airline branch, should make its first flight in 2022.
Originally named Low-Flight Flight Demonstrator from NASA, the agency announced in June that the plane will call the X-59 QueSST forward.
The American Air Force has changed its name as part of the American X-plane's horsemanship, which began in 1947 with the world's first superhighway, the Bell X-1.
"Anyone who works on this important project is a great news and we're delighted with the appointment," said Jaiwon Shin, assistant associate for NASA's Aviation Research Authority.
The X-59 project aims to cut loud sound bumps that resound above the cities in Concorde, as they traveled at a speed of 1,100mph (Mach 1,4 / 1,700 km / h).
The loud booms that appeared whenever Concorde cracked the sound barrier were often described as "disturbing & # 39; by members of the public, which ultimately restricted the plane to flights across the Atlantic when 1976 began carrying passengers.
The X-59 is designed to stop shock waves driven by the movement of airborne particles when the airplane breaks down the sound barrier from the joining – a phenomenon that rejects the sound boom of a supersonic airplane.
NASA hopes that the sound of the beam will be reduced to a quiet bounce, similar to the distant thunder or the door closer.
"The X-59 will continue to have multiple impact waves due to the aircraft wing that creates the elevator and the volume of the aircraft," said Ed Haering, a NASA aeronautical engineer at NASA's Armstrong Flight Research Center in California.
"But the shape of the aircraft is carefully adjusted so that these shock waves do not combine.
"Instead of getting a loud boom boom, you'll get at least two small bells if you even hear them."
NASA's November April will produce similar impact waves using an F-18 fighter jet to perform harsh airborne maneuvers.
The aircraft, pilot pilot NASA Jim Less, will dive from 49,000 feet (15,000 m) and briefly go out on the aisles before it reaches 9,000 meters.
Shockwaves produced by a maneuver concentrate directly below the aircraft in the form of a very loud, centered pair of sound booms.
A few miles from diving spots, the noise moves rapidly as it spreads and slows down.
"The result in this area: a couple of silent boomers – actually soft noise – that people in the field, including NASA researchers and resident volunteers, hardly notice, if they hear anything," the agency wrote in the statement.
QueSST is the latest addition to the series of X-rays and missiles used to test and evaluate new technologies and aerodynamic concepts.
Their X label indicates the status of their mission statement in the US aircraft name.
It all comes back to Chuck Yeager, who smashed the sound barriers, the X-1, a rocket-powered aircraft designed and built in 1945, which in 1948 achieved a speed of almost 1,000 miles per hour (1,600 kmh).
Today's vision for the X-59 has been approved in the latest US budget proposal released by the Office of Management and Budget in Washington in February.
The space agency has received $ 19.9 billion for the next year, $ 500 million (£ 360 million) more than the previous year.
It is unknown how much of the project was allocated for the oversight of the aircraft plan.
QueSST will be used as a testing bed for technologies that could travel to commercial aircraft.
Hope hopes that the first test flight will take place in 2022, with public reaction tests on the final airplane scheduled for next year.
