      NASA pilots flew this YF-12C aircraft from 1971 and 1978 to perform airspeed calibrations and collect propulsion system data at numerous flight conditions.Credit: NASA Supersonic flight became a reality in October 1947, when the Bell X-1 rocket plane broke the sound barrier. NASA’s Lewis Research Center in Cleveland (now, NASA Glenn), which had served as the agency’s aeropropulsion leader since it was established in the 1940s, subsequently helped NASA advance the technology needed to make longer supersonic flights possible.
      A host of military aircraft capable of reaching supersonic speeds followed the Bell X-1. In the 1960s, Lockheed’s family of Blackbirds (the original A-12, the YF-12 interceptor, and the SR-71 reconnaissance vehicle) became the world’s first aircraft able to cruise at supersonic speeds for extended periods. However, the expansion of this capability to larger transport aircraft was difficult, in large part due to the lack of data collected about propulsion systems during longer supersonic flights.
      To solve problems that weren’t found during design-phase testing of these aircraft and to advance crucial technology, like the supersonic mixed-compression inlet, the military loaned two retired YF-12s to the Dryden Flight Research Center (today, NASA Armstrong) in 1969 as part of a collaborative NASA/Air Force effort. They planned to compare data from YF-12 flights to data collected in wind tunnels at NASA’s Ames, Langley, and Lewis Research Centers.
      Bobby Sanders (left) and Robert Coltrin check a full-scale YF-12 flight inlet prior to a February 1972 test run in the NASA Lewis Research Center (now NASA Glenn) 10×10 Supersonic Wind Tunnel. Although the 5-foot 9-inch diameter inlet was large for the test section, no problems aroseCredit: NASA/Martin Brown Lewis’ researchers had studied supersonic inlets in wind tunnels since the early 1950s and were in the midst of an extensive evaluation of supersonic nozzles and inlets using an F-106 Delta Dart. In this new effort, Lewis was responsible for testing a full-scale YF-12 inlet in the center’s 10×10 Supersonic Wind Tunnel and analyzing a 32,500-pound thrust Pratt & Whitney J58 engine in the Propulsion Systems Laboratory (PSL).
      Although mixed-compression inlets, which allowed the engines to operate as turbojets at subsonic speeds and as ramjets at higher Mach numbers, were highly efficient, their design left the engines vulnerable to flow disturbances that often caused “unstarts.” Unstarts produced instantaneous drag that could stall the engine or cause the aircraft to quickly roll or yaw. Lewis researchers tested an actual inlet from a crashed SR-71, which they installed into the 10×10 in November 1971.
      Over the next year, researchers collected aerodynamic data under different conditions in the wind tunnel. They also tested a new inlet control system patented by Lewis engineers Bobby Sanders and Glenn Mitchell that used mechanical valves to protect the aircraft against unstarts. It was the first time the system was tested on a full-scale piece of hardware.
      Researchers also studied the relationships between the airframe, inlet, engine, and control system during normal flight conditions and when experiencing realistic flow disturbances.

The center’s technicians had to take great precautions to protect the instrumentation and control systems from the engine’s 1000-degree-Fahrenheit surface temperatures during the testing. Credit: NASA/Martin Brown In the summer of 1973, a full-scale J-58 engine became the first hardware tested in Lewis’ new PSL second altitude chamber. For the next year, researchers captured data under normal conditions and while using mesh inlet screens to simulate in-flight air-flow distortions.
      The PSL tests also measured the engine’s emissions as part of a larger effort to determine the high-altitude emissions levels of potential supersonic transports.
      While the YF-12 program was terminated in 1979 as the agency’s aeronautical priorities shifted, a year’s worth of ground testing had already been completed in NASA’s wind tunnels and the YF-12s had completed nearly 300 research flights. The program had expanded to include the development of high-temperature instrumentation, airframe pressure and flow mapping, thermal loads, and the inlet control system.
      NASA engineers demonstrated that small-scale models could be successfully used to design full-scale supersonic inlets, while the flight data was used to better understand the effect of subscale models and tunnel interference on data. Perhaps most importantly, the program at Lewis led to a digital control system that improved the response of the supersonic inlet to flow disturbances, which nearly eliminated engine restarts.
      Many of the program’s concepts were integrated into the SR-71’s design in the early 1980s and have contributed to NASA’s continuing efforts over the decades to achieve a supersonic transport aircraft.

      NASA’s DC-8 aircraft takes off from NASA’s Armstrong Flight Research Center Building 703 in Palmdale, California, to conduct test flights as part of the Airborne and Satellite Investigation of Asian Air Quality, or ASIA-AQ mission, that will collect detailed air quality data over several locations in Asia.NASA/Carla Thomas NASA and international researchers are studying the air quality in Asia as part of a global effort to better understand the air we breathe. In collaboration with Korea’s National Institute of Environmental Research (NIER), the Airborne and Satellite Investigation of Asian Air Quality, or ASIA-AQ mission, will collect detailed atmospheric data over several locations in Asia.
      Utilizing aircraft, satellites, and ground-based instruments, the ASIA-AQ team will gather and share data with air quality and government agencies to be used for air quality research and understanding worldwide.
      “Our purpose is to improve the understanding of the factors that control air quality,” said Jim Crawford, principal investigator for the ASIA-AQ mission at NASA’s Langley Research Center in Hampton, Virginia. “Multi-perspective observations are needed because satellites, ground-sites, and aircraft each see different aspects of air quality that need to be connected.”
      While satellite views and ground measurements provide significant data, alone they cannot completely illustrate air quality problems and the sources that cause them. By adding airborne measurements to models along with satellite and ground-based observations, scientists can achieve a multi-dimensional, detailed perspective that evaluates our air quality models from all angles.
      A pair of NASA science aircraft will help provide those additional dimensions to air quality observations. The DC-8 from NASA’s Armstrong Flight Research Center in Edwards, California, is outfitted with 26 instruments and will fly at low-altitudes to collect data from the atmosphere closest to the ground where people and habitats are impacted. Meanwhile, the G-III from NASA’s Langley Research Center in Hampton, Virginia, will fly at 28,000 feet altitude to create a high-resolution map of the pollution distribution in each study area, and how it changes throughout the day. Together with Korean aircraft from NIER, the NASA planes and instruments will supplement and cross-reference the observations made from the ground and satellite instruments.
      “Science missions for air quality [like ASIA-AQ] take a holistic approach of multiple perspectives to better understand our pollution issues,” said Laura Judd, platform scientist for NASA’s G-III aircraft. “If we can better understand how models simulate our air pollution, then we can forecast when these events unfold, and be able to disseminate that information to the public to make informed decisions.”
      Pollution changes as populations shift, economies ebb and flow, and industries move or evolve. The ASIA-AQ project will improve our ability to measure those changes and how they connect to the global scale. Bringing scientists, aircraft, and instruments together from across Asia and around the world, ASIA-AQ demonstrates how scientific advancement is a collaborative effort.
      “Scientists and agencies in each of the participating countries will ensure that ASIA-AQ targets the most important open air quality questions in their specific region,” said Barry Lefer, NASA program scientist for air quality research at NASA Headquarters. “And they’ll be the ones to implement improvements in their forecast models and advocate for policy changes.” ASIA-AQ is a joint effort between NASA and Korea’s National Institute of Environmental Research (NIER) and several international organizations including the Department of Environment and Natural Resources Philippines (DENR), the Universiti Kebangsaan Malaysia (UKM), the Geo-Informatics and Space Technology Development Agency Thailand (GISTDA) and the Ministry of Environment Taiwan (MOENV).
