Integrated Structural Assembly of Advanced Composites (ISAAC) is a state of the art composite manufacturing robot. ISAAC was purchased from Electroimpact and installed in 2015. NASA Langley was the first NASA Center to receive this technology and the third manufacturing facility in the world to receive an ISAAC. The robot has 8 degrees of freedom and an accuracy rate of +/- .05". ISAAC also has several detachable end effectors, making it a versatile machine. Similar robots have become very popular in the automotive and commercial flight industries. At NASA Langley Research Center, ISAAC supports research on the design and manufacturing of composite parts.

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 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.

This image shows the X-59 aircraft’s lower empennage structure, or tail section of the plane, that was installed. The stabilators, the outer surfaces also seen in the photo, attach to the lower empennage and are used to help regulate the aircraft pitch which controls the up and down movement of the motion of the plane. The 13-foot engine will pack 22,000 pounds of propulsion and energy and power the X-plane to its planned cruising speed of Mach 1.4. Once complete, the X-59 aircraft will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land. This aircraft is the centerpiece of NASA’s Quesst mission.

This image shows the extensive ventilation system that has been placed adjacent to the X-59 during the recent painting of the aircraft’s engine inlet. Once the aircraft build and ground testing are complete, the X-59 airplane will begin flight testing, working towards demonstrating the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land.

This is an up-close view of the X-59’s engine inlet – fresh after being painted. The 13-foot F414-GE-100 engine will be placed inside the inlet bringing the X-59 aircraft one step closer to completion. Once fully assembled, the X-59 aircraft will begin flight operations, working toward demonstration of the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump, helping to enable commercial supersonic air travel over land.

Lockheed Martin technicians work to align and check the fastener holes on the X-59’s fuselage skin. 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.

This aircraft is the centerpiece of NASA’s Quesst mission.

The upper empennage, or tail section of the plane, and engine bay is surrounded by a blue gantry that is used to assist with ground installation and removal of the X-59’s lower empennage and engine.

This is a closeup view of the inner workings of the X-59 aircraft. Visible are one the plane’s three lithium-ion batteries (blue box), electrical power system and other wiring components including the vehicle management systems computers (two black boxes) and the white wirings which assist in providing the power that is needed for the aircraft to function in flight. All of these components are essential to maintaining and monitoring the X-59 once it takes to the skies. The X-59 is the centerpiece of the Quesst mission which plans to help enable commercial supersonic air travel over land.

ARCAS Rocket #E1-235 Image taken at Wallops Island

Langley Center Director Floyd Thompson shows Ann Kilgore the "picture of the century." This was the first picture of the earth taken from space. From Spaceflight Revolution: "On 23 August 1966 just as Lunar Orbiter I was about to pass behind the moon, mission controllers executed the necessary maneuvers to point the camera away from the lunar surface and toward the earth. The result was the world's first view of the earth from space. It was called "the picture of the century' and "the greatest shot taken since the invention of photography." Not even the color photos of the earth taken during the Apollo missions superseded the impact of this first image of our planet as a little island of life floating in the black and infinite sea of space." -- Published in James R. Hansen, Spaceflight Revolution: NASA Langley Research Center From Sputnik to Apollo, (Washington: NASA, 1995), pp. 345-346. Mayor Ann Kilgore was married to NASA researcher Edwin Carroll Kilgore. Mrs. Kilgore was Mayor from 1963-1971 and again from 1974-1978.

Women Adequately Filling Posts in NACA Laboratory: Nearly 200 women are employed at the Langley Laboratory of the National Advisory Committee for Aeronautics in a limited capacity as mechanics’ helpers and minor laboratory aids on the jobs formerly handled by men, according to E.H. Derring, of the Aerodynamics Division. Many phases of the operations of various wind tunnels at the laboratory are now handled by women with experienced male supervision. Mr. Derring said, pointing out that the reading of the data indicated on wind tunnel instruments during a test is done in a large measure by women. In addition to reading the instruments and computing and integrating engineering test data obtained from tunnel investigations, the minor laboratory aides assist in the preparation of aircraft models preliminary to testing. Women employees who will serve in the Aerodynamics Division of the Laboratory attend an orientation class for two weeks, during which they receive instruction on phases of the work they will do and their aptitudes for different types of work are evaluated in order that they may be properly placed. More than 100 women are employed in minor laboratory apprentices, performing mechanical work heretofore done by men. These women are employed in the various shops of the laboratory. Women in the woodworking shops are taught to operate 15 different machines in carrying out their assignments. Norfolk new paper article from 1943 by Lee Dickinson.

Test subject sitting at the controls: Project LOLA or Lunar Orbit and Landing Approach was a simulator built at Langley to study problems related to landing on the lunar surface. It was a complex project that cost nearly $2 million dollars. James Hansen wrote: "This simulator was designed to provide a pilot with a detailed visual encounter with the lunar surface; the machine consisted primarily of a cockpit, a closed-circuit TV system, and four large murals or scale models representing portions of the lunar surface as seen from various altitudes. The pilot in the cockpit moved along a track past these murals which would accustom him to the visual cues for controlling a spacecraft in the vicinity of the moon. Unfortunately, such a simulation--although great fun and quite aesthetic--was not helpful because flight in lunar orbit posed no special problems other than the rendezvous with the LEM, which the device did not simulate. Not long after the end of Apollo, the expensive machine was dismantled." (p. 379) Ellis J. White further described this simulator in his paper , "Discussion of Three Typical Langley Research Center Simulation Programs," (Paper presented at the Eastern Simulation Council (EAI's Princeton Computation Center), Princeton, NJ, October 20, 1966.) "A typical mission would start with the first cart positioned on model 1 for the translunar approach and orbit establishment. After starting the descent, the second cart is readied on model 2 and, at the proper time, when superposition occurs, the pilot's scene is switched from model 1 to model 2. then cart 1 is moved to and readied on model 3. The procedure continues until an altitude of 150 feet is obtained. The cabin of the LM vehicle has four windows which represent a 45 degree field of view. The projection screens in front of each window represent 65 degrees which allows limited head motion before the edges of the display can be seen. The lunar scene is presented to the pilot by rear projection on the screens with four Schmidt television projectors. The attitude orientation of the vehicle is represented by changing the lunar scene through the portholes determined by the scan pattern of four orthicons. The stars are front projected onto the upper three screens with a four-axis starfield generation (starball) mounted over the cabin and there is a separate starball for the low window." -- Published in James R. Hansen, Spaceflight Revolution: NASA Langley Research Center From Sputnik to Apollo, (Washington: NASA, 1995), p. 379.
