NASA’s X-59 Quiet Supersonic Aircraft That Can Travel Faster Than Sound, Key Details Here

On January 12, 2024, NASA and Lockheed Martin unveiled the X-59 Quiet Supersonic Aircraft, a revolutionary aircraft poised to change the future of supersonic flight. This one-of-a-kind experimental aircraft, part of NASA's Quesst mission, aims to address the longstanding challenge of sonic booms. The aircraft has the potential to revolutionize air travel by enabling supersonic jets to fly over land without generating ear-splitting sonic booms. The aircraft can prove significant in paving a new generation of commercial aircraft that can travel faster than the speed of sound.

Significance

As per the official website of NASA, for 50 years, the U.S. and other nations have prohibited such flights because of the disturbance caused by loud, startling sonic booms on the communities below. The X-59 is expected to fly at 1.4 times the speed of sound, or 925 mph. Its design, shaping and technologies will allow the aircraft to achieve these speeds while generating a quieter sonic thump.

The X-59 is expected to fly at 1.4 times the speed of sound, or 925 mph. However, the X-59 is not merely a faster airplane; it is a technological marvel designed to overcome the physical barriers that have grounded supersonic travel for decades. Its needle-like shape, with a thin, tapered nose that makes up nearly a third of its length, disrupts the shockwaves that create sonic booms.

Key Features That Will Aid Supersonic Flight

At nearly 99.7 feet long and 29.5 feet wide, the X-59's shape is crucial to its mission of achieving quiet supersonic flight. Its slender fuselage and long, tapered nose, which makes up almost a third of its length, play a key role in breaking up the shock waves that create sonic booms. This innovative design helps to spread out the shock waves, resulting in a much quieter "sonic thump" instead of the thunderous roar typically associated with supersonic aircraft.

The X-59's engine placement is another key factor in its noise reduction strategy. Unlike most aircraft where the engines are mounted under the wings, the X-59's engine is positioned on top of the fuselage. This placement helps to further reduce the strength of the shock waves and prevents them from merging and amplifying into a sonic boom.

The cockpit is located further back than in a traditional aircraft, nearly halfway down the fuselage. This unconventional placement made it impossible to have a forward-facing window. But instead of compromising on visibility, the Quesst team developed the eXternal Vision System (EVS). This system uses a series of high-resolution cameras mounted on the nose and tail of the aircraft, feeding a panoramic 4K display in the cockpit.
