超音速飞行

NASA’s X-59 research aircraft moves from its construction site to the flight line – or the space between the hangar and the runway – at Lockheed Martin Skunk Works in Palmdale, California, on June 16, 2023. This milestone kicks off a series of ground tests to ensure the X-59 is safe and ready to fly. The X-59 is designed to fly faster than Mach 1 while reducing the resulting sonic boom to a thump for people on the ground. NASA will evaluate this technology during flight tests as part of the agency’s Quesst mission, which helps enable commercial supersonic air travel over land.

NASA’s X-59 sits in support framing while undergoing the installation of its lower empennage, or tail section, at Lockheed Martin Skunk Works in Palmdale, California, in this image from late March 2023. Once complete, the X-59 aircraft—the centerpiece of NASA’s Quesst mission—is designed to demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump. The Quesst mission will then fly the X-59 over several U.S. communities to gather data on human responses to the sound generated during supersonic flight and deliver that data set to U.S. and international regulators.
