NASA X-59静音超音速试验机首飞满一年：一年又飞40次，最高速度1.53马赫、高度逾5.6万英尺
美国国家航空航天局（NASA）10月28日表示，其 X-59 静音超音速研究机自 2025 年 10 月 28 日首飞以来已经满一年。一年间，这架隶属 Quesst 任务的试验机又完成了 40 次飞行，最高飞行高度超过 56,000 英尺，最高速度达到 1.53 马赫。X-59 的试飞由位于加州 Edwards 的 NASA Armstrong 飞行研究中心一带展开。
NASA 介绍，2025 年 10 月 28 日的首飞以低空、低速飞行为主，目的是做系统检查；此后一年，X-59 持续扩展飞行包线，在 Quesst 任务将实际使用的高度、速度与条件组合下反复试飞。今年 9 月，该机曾在一周内完成 6 次飞行、创下自身单周飞行纪录。
X-59 的机身外形经过专门设计：按设计指标，它在 55,000 英尺高度以 1.4 马赫巡航时，地面听到的不是传统超音速飞机的巨大音爆，而是一声较轻的「砰」响，NASA 预计其声响约相当于 20 英尺外关上车门的声音。
下一步，项目团队将在继续扩展飞行包线的同时，转入新的测试阶段：声学验证，重点分析 X-59 实际发出的声响。NASA 将在后续试飞中记录这种「音爆轻响」，并调查公众的反应，把数据提交给美国及国际监管机构，为制定以数据为依据的陆上超音速飞行噪声新标准提供参考。
NASA 表示，Quesst 任务的目标是为陆上空域的商业超音速飞行开启新时代，探索更快速空中出行的新市场。
NASA's X-59 Quiet Supersonic Jet Marks One Year Since First Flight: 40 More Flights, Top Speed Mach 1.53
NASA said on Oct. 28 that its X-59 quiet supersonic research aircraft has marked one year since its first flight on Oct. 28, 2025. In that year, the one-of-a-kind jet at the heart of the Quesst mission has completed 40 additional flights, reaching a maximum altitude of more than 56,000 feet and speeds up to Mach 1.53. The test campaign is flown from NASA's Armstrong Flight Research Center in Edwards, California.
While the first flight focused on low, slow flights to conduct systems checks, NASA said the X-59 has since spent the year expanding its flight envelope, flying at the altitudes, speeds, and conditions that will be used for all aspects of the Quesst mission. In September, the aircraft set its own record by completing six flights in one week.
The X-59 is shaped so that, at its intended quiet supersonic cruise of Mach 1.4 at 55,000 feet, people on the ground will not hear a loud sonic boom. Instead, they will hear a softer thump that NASA projects will sound like a car door closing from about 20 feet away.
In the coming months, the team will continue expanding the flight envelope while transitioning toward a new phase of testing: acoustic validation, focused on analyzing the sounds the X-59 makes. NASA will study and record those sonic thumps and survey how people respond, sharing the reactions with national and international regulators to inform new, data-driven acceptable noise thresholds for supersonic commercial flight over land.
NASA said the Quesst mission aims to help enable a new era of commercial supersonic flight over land, exploring the potential for a new market of faster air travel.
