NASA’s X-59 Quiet Supersonic Aircraft Begins Taxi Tests | NASA Armstrong
NASA’s X-59 quiet supersonic research aircraft has started taxi tests, marking the first time this one-of-a-kind experimental aircraft has moved under its own power. The aircraft completed its first low-speed taxi test, allowing engineers and flight crews to monitor how it handled moving across the runway under its own power. Taxi tests mark the final major ground test before flight operations begin. The X-59 is the centerpiece of NASA’s Quesst mission. It aims to demonstrate quiet supersonic flight by reducing the loud sonic boom to a quieter “thump”. Data gathered during X-59 research flights will be shared with the U.S. and international regulators to inform the establishment of new, data-driven acceptable noise thresholds related to supersonic commercial flight over land.
The X-59’s first flight is expected to occur in 2025.
The X-59’s engine, a modified F414-GE-100, packs 22,000 pounds of thrust. This will enable the X-59 to achieve the desired cruising speed of Mach 1.4 (925 miles per hour) at an altitude of approximately 55,000 feet. It sits in a nontraditional spot–atop the aircraft—to aid in making the X-59 quieter.
The X-59's goal is to help change existing national and international aviation rules that ban commercial supersonic flight over land.
