NASA Lockheed Martin X-59 QueSST approved for assembly


After a major project review by senior management at NASA headquarters in Washington on Thursday, NASA used large X-type aircraft for final assembly and system integration for the first time in more than three decades.

The X-59 Quiet Supersonic Technology (QueSST), named after its full name, is an experimental jet developed by the space agency. The special aeronautical design is designed to reduce sound waves when the aircraft reaches supersonic speed.

The ambitious proof-of-concept project is the result of lengthy research and development, and the design has endured a major technical hurdle this week and received a definitive assembly license announced by NASA.

Known as Key Decision Point D (KDP-D), the management assessment was the last procedural obstacle that the X-59 Quiet Supersonic Technology (QueSST) aircraft had to clear up, after which officials gathered again at the end of 2020 to complete the first flight of the aircraft in 2021. to approve.

“With the completion of KDP-D, we have proven that the project is on schedule, well planned and on schedule. We are ready to continue this historical fact-finding mission for the US air passenger audience,” NASA Aviation The Deputy Director of the Bob Pearce Space Agency said.

The shape of the X-59 reduces the sound of the sonic tree reaching the ground to a soft thump when it is heard. It will fly over some communities in the United States and generate data from sensors and local people to assess public perception. The data helps regulators to develop new rules to enable commercial supersonic air transport.

Lockheed Martin Airlines’ Skunk plant in Palmdale, California, continues to build the X-59 at a contract price of $ 247.5 million plus incentive fees.

Actively set three main work areas to produce the main body, wings and tail of the aircraft. The final assembly and integration of the aircraft system, including the innovative vision system of the cockpit, is planned for the end of 2020.

This means that the X-59 is expected to perform its first test flight in 2021 and the details will be confirmed and approved next year.

X-59 QueSST development and construction management is part of the Low Altitude Flight Demonstrator project, which is part of NASA’s Integrated Aviation System Program.

In the 1960s, the development of supersonic passenger aircraft is expected to completely change the concept of international travel, completing the flight from New York to Paris in 3.5 hours, which is half the time of a traditional subsonic flight.

With the famous Concorde, that incredible travel time became the luxury reality of a rich jet, but the extreme noise pollution from the sonic tree released by the plane that broke the speed of the sound made the supersonic dream come true.
