New Supersonic Aircraft Designs Aim to Minimize Sonic Boom Impact - NASA's X-59 QueSST Aims to Revolutionize Supersonic Travel
NASA's X-59 QueSST is a revolutionary aircraft that aims to overcome the longstanding challenge of sonic booms, potentially ushering in a new era of faster air travel over land.
Through innovative design and technology, the X-59 is capable of producing a quieter "sonic thump" rather than the traditional loud sonic boom, addressing a key barrier to supersonic flight.
The X-59's unique shape is designed to generate a "sonic thump" rather than a traditional sonic boom, which could pave the way for lifting the ban on civilian supersonic flights over land.
The aircraft features an external vision system that displays a real-time view of the front of the X-59 on a screen, as the long nose design blocks the forward-facing window, providing the pilot with enhanced visibility.
NASA and Lockheed Martin plan to conduct the first flight of the X-59 in 2023 to validate the aircraft's ability to generate a quieter sonic thump, a crucial step in demonstrating the feasibility of supersonic travel over land.
The X-59's highly streamlined and elongated design is a key factor in minimizing the sonic boom impact, as it helps to distribute the shockwaves more evenly, reducing the intensity of the pressure waves.
The data gathered from the X-59's acoustic validation tests could potentially lead to regulators revising sound-based rules and lifting the longstanding ban on civilian supersonic flights over land in the United States.
While the X-59 is not designed for commercial use, the insights gained from this experimental aircraft could pave the way for a new generation of supersonic airliners that can travel faster than the speed of sound while minimizing the impact on the public.
