Lockheed Martin announced the completion of the "drafting" phase of development of the X-59 Quiet Supersonic Technology (QueSST) aircraft and the beginning of its direct production. The first test flight is scheduled for 2021.
Long-term cooperation between Lockheed Martin and NASA prompted the goal of creating the X-plane QueSST - testing technologies that in the future will make it possible to obtain a low-noise commercial supersonic aircraft that does not create problems for urban residents.
With the launch of QueSST test flights, NASA plans to use it to collect the necessary technical information. In addition, he is tasked with popularizing the future commercial supersonic airliner that meets the highest environmental criteria.
X-59 QueSST will fly at an altitude of 17, 000 m at a speed of 1, 512 km / h, while the noise at the moment of breaking the sound barrier will not exceed 75 dB, which corresponds to the loudness of a bang when the car door is closed.
