NASA's X-59 Quiet Supersonic Plane Achieves Historic Test Flight

NASA and Lockheed Martin's experimental X-59 aircraft has achieved a significant milestone with its first test flight, marking a pivotal moment in the future of supersonic travel. The flight took place on October 28, 2023, from Lockheed Martin's Skunk Works facility in Palmdale, California, and landed at NASA's Armstrong Flight Research Center in Edwards, California.

The test lasted about one hour, during which the plane reached a maximum speed of approximately 240 miles per hour and flew at an altitude of 12,000 feet. It is important to note that this flight did not reach supersonic speeds; instead, it focused on checking critical systems.

The X-59 is designed to fly at a maximum speed of Mach 1.4, or about 925 miles per hour, nearly double the speed of a Boeing 747, and is intended to operate at altitudes of 55,000 feet. Its unique design features a wingspan of 30 feet and a length of 100 feet, resembling a swordfish, with a long, chisel-shaped nose that alters the formation of shockwaves produced during flight.

This innovative shape is key to the X-59's capability to produce a quieter sonic event, termed a 'thump,' rather than the disruptive sonic booms associated with traditional supersonic aircraft. This advancement is crucial, as supersonic flight has been banned over populated areas in the U.S. since 1973 due to the disruptive nature of sonic booms.

Previous tests in the 1960s revealed that sonic booms could cause damage to buildings and startled residents, leading to public opposition against supersonic travel. The X-59's design aims to mitigate this issue by creating smaller shockwaves that combine to form a less jarring sound.

Future test flights will involve the aircraft reaching supersonic speeds to assess public reactions to the quieter 'thumps.' This could potentially pave the way for a resurgence in commercial supersonic travel in the United States, albeit with a significantly reduced noise footprint.

As NASA and Lockheed Martin continue their collaboration, the successful test flight of the X-59 represents a significant step toward revolutionizing how we think about air travel and its impact on communities.
