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.

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.

This is an image of the X-59 inlet with a safety covering. The inlet’s purpose is to adjust air speeds before they pass through the aircraft’s engine. The purpose of the covering is to protect the inlet and engine from foreign objects.
This photo shows the X-29 during a 1991 research flight. Smoke generators in the nose of the aircraft were used to help researchers see the behavior of the air flowing over the aircraft. The smoke here is demonstrating forebody vortex flow. This mission was flown September 10, 1991, by NASA research pilot Rogers Smith.

Technicians examine a scale model of the space shuttle used to obtain pressure data during tests in the 10- by 10-Foot Supersonic Wind Tunnel at the National Aeronautics and Space Administration (NASA) Lewis Research Center. Lewis researchers used the 10- by 10 tunnel extensively in the 1970s to study shuttle configurations in order to forecast conditions during an actual flight. These tests included analysis of the solid rocket boosters’ aerodynamics, orbiter forebody angle -of -attack and air speed, base heating for entire shuttle, and engine-out loads. The test seen in this photograph used a 3.5- percent scale aluminum alloy model of the entire launch configuration. The program was designed to obtain aerodynamic pressure data. The tests were part of a larger program to study possible trouble areas for the shuttle’s new Advanced Flexible Reusable Surface Insulation. The researchers obtained aeroacoustic data and pressure distributions from five locations on the model. Over 100 high-temperature pressure transducers were attached to the model. Other portions of the test program were conducted at Lewis’ 8- by 6-Foot Supersonic Wind Tunnel and the 11- by 11-Foot Transonic Wind Tunnel at Ames Research Center.
Following the successful installation of mounting brackets, technicians successfully installed the pallet for the eXternal Visibility System, or XVS, onto the X-59 Quiet SuperSonic Technology X-plane, also known as X-59 QueSST. The pallet installation marks an assembly milestone as the first NASA flight systems hardware to be installed onto the vehicle. X-59 will fly to demonstrate the ability to produce quiet thumps at supersonic speeds, instead of the typical, loud sonic booms associated with supersonic flight.

The first of three X-43A hypersonic research aircraft and its modified Pegasus® booster rocket recently underwent combined systems testing while mounted to NASA's NB-52B carrier aircraft at the Dryden Flight Research Center, Edwards, California. The combined systems test was one of the last major milestones in the Hyper-X research program before the first X-43A flight. One of the major goals of the Hyper-X program is flight validation of airframe-integrated, air-breathing propulsion system, which so far have only been tested in ground facilities, such as wind tunnels. The X-43A flights will be the first actual flight tests of an aircraft powered by a revolutionary supersonic-combustion ramjet ("scramjet") engine capable of operating at hypersonic speeds above Mach 5 (five times the speed of sound). The X-43A design uses the underbody of the aircraft to form critical elements of the engine. The forebody shape helps compress the intake airflow, while the aft section acts as a nozzle to direct thrust. The 12-foot, unpiloted research vehicle was developed and built by MicroCraft Inc., Tullahoma, Tenn., under NASA contract. The booster, built by Orbital Sciences Corp., Dulles, Va., will accelerate the X-43A after the X-43A/booster "stack" is air-launched from NASA's venerable NB-52 mothership. The X-43A will separate from the rocket at a predetermined altitude and speed and fly a pre-programmed trajectory, conducting aerodynamic and propulsion experiments until it descends into the Pacific Ocean. Three research flights are planned, two at Mach 7 and one at Mach 10.
The second of three X-43A hypersonic research aircraft, shown here in its protective shipping jig, arrived at NASA's Dryden Flight Research Center, Edwards, California, on January 31, 2001. The arrival of the second X-43A from its manufacturer, MicroCraft, Inc., of Tullahoma, Tenn., followed by only a few days the mating of the first X-43A and its specially-designed adapter to the first stage of a modified Pegasus® booster rocket. The booster, built by Orbital Sciences Corp., Dulles, Va., will accelerate the 12-foot-long, unpiloted research aircraft to a predetermined altitude and speed after the X-43A/booster "stack" is air-launched from NASA's venerable NB-52 mothership. The X-43A will then separate from the rocket and fly a pre-programmed trajectory, conducting aerodynamic and propulsion experiments until it impacts into the Pacific Ocean. Three research flights are planned, two at Mach 7 and one at Mach 10 (seven and 10 times the speed of sound respectively) with the first tentatively scheduled for early summer, 2001. The X-43A is powered by a revolutionary supersonic-combustion ramjet ("scramjet") engine, and will use the underbody of the aircraft to form critical elements of the engine. The forebody shape helps compress the intake airflow, while the aft section acts as a nozzle to direct thrust. The X-43A flights will be the first actual flight tests of an aircraft powered by an air-breathing scramjet engine.
A Lockheed Martin technician prepares holes for installation of the fuselage panel on the X-59. The fuselage is the section of the aircraft that contains the cockpit.

The team at Lockheed Martin Skunk Works in Palmdale, California, merged the major sections of the X-59 Quiet SuperSonic Technology aircraft, which includes the wing, tail assembly, and fuselage or forward section. This marks the first time the X-59 resembles an actual aircraft. (Pictured here is a overhead view of the X-59 as it comes together for the major assembly merger in summer 2021.)
