La Nasa veut faire voler un F-15 dans le sillage de l’onde de choc supersonique du X-59
NASA’s Supersonic Dream: Will the X-59 Quietly Break the Sound Barrier?
Edwards Air Force Base, California – For years, NASA has been working on a revolutionary aircraft, the X-59 QueSST, designed to break the sound barrier without the deafening sonic boom. This groundbreaking technology could pave the way for the return of supersonic passenger flights over land, a possibility banned in the U.S. since 1974.
The X-59’s unique, elongated nose is key to its quiet supersonic flight. The design is intended to reshape the shock waves generated by the aircraft, diverting them upward and minimizing the ground-level noise.
But will this innovative design work as predicted?
to find out, NASA has devised a clever plan. During the X-59’s test flights, a chase plane, an F-15B fighter jet equipped with specialized sensors, will fly in close formation behind the experimental aircraft. These sensors will meticulously measure the shock waves produced by the X-59 as it approaches and surpasses the speed of sound.
“this is a critical step in validating our simulations and ensuring the X-59 can achieve its goal of quiet supersonic flight,” said a NASA spokesperson.
the data collected by the F-15B will be invaluable in determining the effectiveness of the X-59’s design. If successful, this technology could revolutionize air travel, making supersonic flight a reality for passengers onc again.
The X-59’s first flight is eagerly anticipated by aviation enthusiasts and the scientific community alike. The results of these tests will not only determine the fate of the X-59 project but could also have far-reaching implications for the future of supersonic travel.
NASA Prepares to Measure Sonic Booms with Innovative Technology
Edwards Air Force Base, CA – NASA is gearing up for a groundbreaking test of technology designed to measure the unique shock waves produced by its experimental X-59 QueSST aircraft. This silent supersonic demonstrator aims to revolutionize air travel by reducing the disruptive sonic booms associated with supersonic flight.
The test will involve specialized probes, known as “sondes,” mounted on a NASA F-15B research aircraft. These cone-shaped probes, equipped with five pressure sensors, will be positioned to capture data as the F-15B flies through the shock wave generated by the X-59.
“These sondes will provide invaluable data on the direction, pressure, and speed of the airflow within the shock wave,” said a NASA spokesperson. “This facts will help us validate our theoretical models and refine our understanding of how sonic booms are formed.”
One sonde will be mounted on a 6-foot boom extending from the nose of the F-15B, allowing it to collect data in close proximity to the X-59. A second sonde will be used to measure airflow characteristics at varying altitudes below the X-59.
While the X-59 has yet to achieve supersonic flight,NASA recently conducted successful engine tests,marking a significant milestone in the project. In the meantime, the agency will conduct test flights with two F-15s flying in formation at supersonic speeds, simulating the conditions the sondes will encounter during X-59 testing.
This innovative approach to sonic boom measurement is a crucial step towards realizing NASA’s goal of enabling quieter supersonic flight over land. The data collected during these tests will pave the way for the future of supersonic travel, potentially opening up new possibilities for faster and more efficient air transportation.

Please tell me what kind of negotiation you’d like me to help with.I need some context to be effective.
For example, tell me:
What is the subject of the negotiation? (e.g.,Salary, contract terms, buying a car, resolving a dispute)
Who are the parties involved? (e.g., You and your employer, two businesses, neighbors)
What are your goals? (e.g., Get the highest possible salary, secure favorable contract terms, get a fair price for the car)
What are the other party’s likely goals? (e.g.,Keep salary costs down,minimize risk,sell the car for the highest price)
* What is your BATNA (Best Choice To a Negotiated Agreement)? (e.g., Another job offer, walking away from the deal, pursuing legal action)
The more facts you provide, the better I can assist you in preparing a winning negotiation strategy.Let’s work together to achieve a positive outcome!
