美完成X-59静音超音速飞机首飞

Core Viewpoint - NASA and Lockheed Martin successfully completed the first flight of the experimental quiet supersonic aircraft X-59, marking a significant step in overcoming noise issues associated with supersonic commercial flight [1] Group 1: Aircraft Specifications and Performance - The X-59 is approximately 30 meters long with a wingspan of about 9 meters, designed to cruise at a speed of 1.4 Mach, which is 1.4 times the speed of sound [1] - The aircraft's unique shape and noise reduction design significantly diminish the sound of sonic booms reaching the ground [1] Group 2: Development and Future Implications - The X-59 aims to address the primary obstacle that currently limits supersonic commercial aircraft from flying over land, which is the noise issue [1] - The development and flight testing of the X-59 will lay the groundwork for the next generation of supersonic aircraft, which are expected to transport passengers and cargo at twice the speed of current commercial jets efficiently and sustainably [1] Group 3: Industry Impact - NASA's acting administrator, Sean Duffy, highlighted that the X-59 showcases the vitality of American aviation innovation, reinforcing the country's leading position in the aerospace sector and potentially transforming future flying experiences for the public [1]
