The pilot of NASAÕs X-59 Quiet SuperSonic Technology, or QueSST, aircraft will navigate the skies in a cockpit unlike any other. There wonÕt be a forward-facing window. ThatÕs right; itÕs actually a 4K monitor that serves as the central window and allows the pilot to safely see traffic in his or her flight path, and provides additional visual aids for airport approaches, landings and takeoffs. The 4K monitor, which is part of the aircraftÕs eXternal Visibility System, or XVS, displays stitched images from two cameras outside the aircraft combined with terrain data from an advanced computing system. The two portals and traditional canopy are real windows however, and help the pilot see the horizon. The displays below the XVS will provide a variety of aircraft systems and trajectory data for the pilot to safely fly. The XVS is one of several innovative solutions to help ensure the X-59Õs design shape reduces a sonic boom to a gentle thump heard by people on the ground. Though not intended to ever carry passengers, the X-59 boom-suppressing technology and community response data could help lift current bans on supersonic flight over land and enable a new generation of quiet supersonic commercial aircraft.

The X-59 Quiet SuperSonic Technology (QueSST) aircraft is taking shape at the Lockheed Martin Skunk Works facility in Palmdale, California. The team positioned the X-59 QueSST's nose at the front of the aircraft. As one of the more recognizable features of the X-59, the nose makes up almost a third of the aircraft length and will be essential in shaping shock waves during supersonic flight, resulting in quiet sonic thumps instead of loud sonic booms. The nose was attached and then removed from the front of the aircraft in preparation for its shipment to Fort Worth, Texas where it will undergo additional testing. The X-59 will fly at supersonic speeds above communities as part of the Low-Boom Flight Demonstration mission, during which NASA will gather community feedback to the sound of quiet supersonic flight. These findings will be shared with regulators to inform decisions on current restrictions of supersonic flight over land.

NASA is targeting 2022 for the first flight of the X-59 Quiet SuperSonic Technology (QueSST) research aircraft. Its mission – fly over communities to collect data that could cut passenger travel time in half without disturbing people on the ground. NASA’s X-59 is equipped with supersonic technologies that aid in lowering the sound of the sonic boom. In this picture, the black rectangle panels are the air intakes for the environmental control system (ECS) that regulates the temperature, cabin pressure, and air distribution. The silver grate located at the rear of one of the ECS panels is the exhaust — both of these sections are traditionally housed on the underside of the plane. By placing these features on top of the X-59 wing, the wing blocks and prevents the ECS exhaust from interacting with the shock waves on the bottom of the aircraft. This unique design approach to re-shaping the shock wave pattern substantially reduces the sonic boom to more of a sonic “thump” when it reaches the ground.

The Fan Noise Test Facility built at the Lewis Research Center to obtain far-field noise data for the National Aeronautics and Space Administration (NASA) and General Electric Quiet Engine Program. The engine incorporated existing noise reduction methods into an engine of similar power to those that propelled the Boeing 707 or McDonnell-Douglas DC-8 airliner. The new the low-bypass ratio turbofan engines of the 1960s were inherently quieter than their turbojet counterparts, researchers had a better grasp of the noise generation problem, and new acoustic technologies had emerged. Lewis contracted General Electric in 1969 to build and aerodynamically test three experimental engines with 72-inch diameter fans. The engines were then brought to Lewis and tested with an acoustically treated nacelle. This Fan Noise Test Facility was built off of the 10- by 10-Foot Supersonic Wind Tunnel’s Main Compressor and Drive Building. Lewis researchers were able to isolate the fan’s noise during these initial tests by removing the core of the engine. The Lewis test rig drove engines to takeoff tip speeds of 1160 feet per second. The facility was later used to test a series of full-scale model fans and fan noise suppressors to be used with the quiet engine. NASA researchers predicted low-speed single-stage fans without inlet guide vanes and with large spacing between rotors and stators would be quieter. General Electric modified a TF39 turbofan engine by removing the the outer protion of the fan and spacing the blade rows of the inner portion. The tests revealed that the untreated version of the engine generated less noise than was anticipated, and the acoustically treated nacelle substantially reduced engine noise.

Event: Forebody and Nose - Windtunnel Testing A model of the X-59 forebody is shown in the Lockheed Martin Skunk Works’ wind tunnel in Palmdale, California. These tests gave the team measurements of wind flow angle around the aircraft’s nose and confirmed computer predictions made using computational fluid dynamics (CFD) software tools. The data will be fed into the aircraft flight control system to tell the pilot the aircraft’s altitude, speed and angle. This is part of NASA’s Quesst mission which plans to help enable supersonic air travel over land.
Event: Manufacturing Area From Above A overhead view of the X-59 with its nose on. The X-59’s nose is 38-feet long – approximately one third of the length of the entire aircraft. The aircraft, under construction at Lockheed Martin Skunk Works in Palmdale, California, will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump.

NASA's F-15B Aeronautics Research Test Bed performs a calibration flight of the shock-sensing probe over Edwards, California, on Aug. 6, 2024. The probe will measure shock waves from NASA's X-59.
NASA’s X-59 quiet supersonic research aircraft sits on the ramp at Lockheed Martin Skunk Works in Palmdale, California during sunrise, shortly after completion of painting. With its unique design, including a 38-foot-long nose, the X-59 was built to demonstrate the ability to fly supersonic, or faster than the speed of sound, while reducing the typically loud sonic boom produced by aircraft at such speeds to a quieter sonic “thump”. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land, currently banned in the United States, by making sonic booms quieter.
NASA test pilot Nils Larson inspects the agency’s F-15D research aircraft at NASA’s Armstrong Flight Research Center in Edwards, California, ahead of a calibration flight for a newly installed near-field shock-sensing probe. Mounted on the F-15D, the probe is designed to measure shock waves generated by the X-59 quiet supersonic aircraft during flight. The data will help researchers better understand how shock waves behave in close proximity to the aircraft, supporting NASA’s Quesst mission to enable quiet supersonic flight over land.

NASA’s F-15D research aircraft conducts a test flight near Edwards, California, with a newly installed near-field shock-sensing probe. Identical to a previously flown version that was intended as the backup, this new probe will capture shock wave data near the X-59 as it flies faster than the speed of sound, supporting NASA’s Quesst mission.
NASA’s X-59 quiet supersonic research aircraft sits in its run stall at Lockheed Martin’s Skunk Works facility in Palmdale, California, prior to its first engine run. Engine runs are part of a series of integrated ground tests needed to ensure safe flight and successful achievement of mission goals. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land by making sonic booms quieter.
