"The X-59 will generate a lower sonic thump thanks to its unique design. It was given a long, slender nose that accounts for about a third of the total length and breaks up pressure waves that would otherwise merge on other parts of the airplane. The engine was mounted on top of the X-59's fuselage, rather than underneath as on a fighter jet, to keep a smooth underside that limits shock waves."
"Perhaps the most striking change on the X-59 is that it does not have a glass cockpit window. Instead, the cockpit is fully enclosed to be as aerodynamic as possible, and the pilot watches a camera feed of the outside world on a 4K monitor known as the eXternal Visibility System. You can't see very clearly through glass when you look at it at a very shallow angle,"
The X-59 uses a long, slender nose comprising about one-third of the aircraft to break up pressure waves and reduce sonic thump. The engine is mounted atop the fuselage to preserve a smooth underside and direct sound upward. The single-seat, single-engine jet measures 99.7 feet long and 29.5 feet wide, and will cruise at Mach 1.4 at 55,000 feet using a modified General Electric F414 engine. The cockpit is enclosed and relies on a 4K eXternal Visibility System camera feed to maintain aerodynamic shape. NASA intends to supply data to enable quieter future supersonic commercial aircraft.
