NASA and Lockheed Martin Unveil X-59 Quiet Supersonic Aircraft: Paving the Way for a Sonic Boom Revolution

The reveal took place at Lockheed Martin's Skunk Works facility in Palmdale, California, during a ceremony attended by NASA Deputy Administrator Pam Melroy and other senior officials.

A look into the X-59

The X-59 is the centerpiece of NASA's Quesst (Quiet Supersonic Technology) mission, a bold initiative aimed at gathering crucial data to challenge and potentially overturn the long-standing regulations prohibiting commercial supersonic flight over land. For the past 50 years, both the United States and other nations have enforced strict bans due to the disruptive sonic booms generated by supersonic aircraft, causing disturbances to communities below.

Characteristics

With the ability to fly at 1.4 times the speed of sound, or 925 mph, the X-59 is designed to produce a quieter sonic thump, addressing the noise concerns associated with traditional supersonic flight. NASA's ambitious goal is to use the data collected from the X-59 to influence regulators in reconsidering and relaxing these stringent rules.

People's reaction

NASA's Pam Melroy expressed her admiration for the achievement, stating, “This is a major accomplishment made possible only through the hard work and ingenuity from NASA and the entire X-59 team. In just a few short years, we’ve gone from an ambitious concept to reality. NASA’s X-59 will help change the way we travel, bringing us closer together in much less time.”

Bob Pearce, associate administrator for aeronautics research at NASA Headquarters, emphasized the potential benefits of the Quesst mission, stating, “It’s thrilling to consider the level of ambition behind Quesst and its potential benefits. NASA will share the data and technology we generate from this one-of-a-kind mission with regulators and with industry. By demonstrating the possibility of quiet commercial supersonic travel over land, we seek to open new commercial markets for U.S. companies and benefit travelers around the world.”

What's next

Now that the X-59's rollout is complete, the Quesst team will focus on integrated systems testing, engine runs, and taxi testing in preparation for its first flight later this year. Following the initial flight, the aircraft will conduct its first quiet supersonic flight. Flight tests will take place at Lockheed Martin Skunk Works before the X-59 is transferred to NASA’s Armstrong Flight Research Center in Edwards, California, which will serve as its operational base.

John Clark, vice president and general manager at Lockheed Martin Skunk Works, expressed pride in being part of this transformative journey: “Across both teams, talented, dedicated, and passionate scientists, engineers, and production artisans have collaborated to develop and produce this aircraft. We’re honored to be a part of this journey to shape the future of supersonic travel over land alongside NASA and our suppliers.”

Upon completion of flight tests, NASA plans to fly the X-59 over selected cities across the U.S. to collect data on the sound generated by the aircraft and public perceptions of it. The gathered information will be shared with the Federal Aviation Administration (FAA) and international regulators to contribute to the ongoing dialogue about supersonic flight regulations.

What's special

What sets the X-59 apart is its status as a unique experimental airplane rather than a prototype. The technologies incorporated into the X-59 are intended to pave the way for future generations of quiet supersonic aircraft. With a length of 99.7 feet and a width of 29.5 feet, the aircraft's design is crucial to achieving quiet supersonic flight. Its thin, tapered nose, constituting almost a third of its length, plays a key role in breaking up shock waves that would otherwise result in disruptive sonic booms.

Notably, the cockpit is positioned almost halfway down the length of the aircraft, eschewing a forward-facing window. To compensate for this, the Quesst team developed the eXternal Vision System, a series of high-resolution cameras feeding a 4K monitor in the cockpit, ensuring the pilot's visibility and control.

Additionally, the X-59 features an innovative design with the engine mounted on top and a smooth underside to prevent shockwaves from merging behind the aircraft, thus mitigating the potential for generating sonic booms.

The future is here

John Clark of Lockheed Martin Skunk Works underlined the industry's commitment to pushing the boundaries: "We're thrilled to take on this challenge alongside NASA, whose quiet supersonic technology mission will have lasting, transformational impacts for people around the world. This project is just one example of the broader ingenuity of our industry as we continually strive to push the envelope of what's possible."

The rollout ceremony for the X-59 is not just a tradition but a celebration of technical advancements, collaboration, and innovation derived from years of research, development, and production. The X-59 stands as a testament to the collective expertise of NASA and Lockheed Martin, symbolizing a historic moment in aeronautics.

Greg Ulmer, executive vice president of Lockheed Martin Aeronautics, expressed his pride in the teams that made this achievement possible, stating, "The entire X-59 team leaned into the expertise of both legendary organizations, NASA and Lockheed Martin, to ensure success for this program. I am extremely proud of everyone who made this historic moment possible." As the X-59 prepares for its upcoming flight tests and the potential transformation of supersonic travel, the aviation world eagerly awaits the promising future heralded by this pioneering aircraft.
