Definition: In this task, you are given a set of context paragraphs, some supporting facts and an answer of a question. Your task is to generate question for given answer based on set of context paragraphs, supporting facts and an answer.
Input: Context_1 : Aerodynamics, from Greek "aer" (air) + (dynamics), the study of the motion of air, particularly its interaction with a solid object, such as an airplane wing. Aerodynamics is a sub-field of fluid dynamics and gas dynamics, and many aspects of aerodynamics theory are common to these fields. The term "aerodynamics" is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. Context_2 : The Neutral Buoyancy Simulator was a neutral buoyancy pool located at NASA's George C. Marshall Space Flight Center (MSFC). Engineers and astronauts developed hardware and practiced procedures in this tank from its completion in 1968 through its decommissioning in 1997. Marshall recognized the need for underwater simulations of extra-vehicular activities (EVAs) and developed three successively larger tanks for the purpose. The Neutral Buoyancy Simulator contributed significantly to the American manned space program. Skylab, the Space Shuttle, Hubble Space Telescope, and the International Space Station have all benefited from the Neutral Buoyancy Simulator. Until Johnson Space Center constructed the Weightless Environment Test Facility in the mid-1970s, MSFC had the only NASA-owned test facility that allowed engineers and astronauts to become familiar with the dynamics of body motion under weightless conditions. Context_3 : The U.S. Air Force Test Pilot School (TPS) graduated the following notable alumni who made significant contributions to the aerospace field. The school's mission is to produce experimental test pilots, flight test engineers, and flight test navigators to lead and conduct test and evaluation of aerospace weapon systems. The school was established on September 9, 1944 as the Flight Test Training Unit at Wright-Patterson Air Force Base (AFB) in Dayton, Ohio. To take advantage of the uncongested skies and superb flying weather, the school was moved on February 4, 1951 to its present location at Edwards Air Force Base in the Mojave Desert of Southern California. Edwards AFB is the home of the Air Force Flight Test Center and has been an integral part of flight testing for over fifty years. Context_4 : The von Karman Gas Dynamics Facility at Arnold Engineering Development Complex, Arnold Air Force Base, Tennessee, provide aerothermal ground test simulations of hypersonic flight over a wide range of velocities and pressure altitudes. The facility consists of three Hypersonic wind tunnels: Tunnel A, B, and C. The wind tunnels can be run for several hours at a time thanks to a 92,500 horsepower air compressor plant system. The test unit is owned by the United States Air Force and operated by Aerospace Testing Alliance. Context_5 : The Royal Australian Air Force's Aircraft Research and Development Unit (ARDU) plans, conducts and analyses the results of ground and flight tests of existing and new Air Force aircraft. ARDU consists of four flights located at RAAF Bases Edinburgh, Amberley, Richmond and Williamtown, staffed by qualified test pilots, flight test engineers and flight test system specialists. Up until 2016 the Squadron also conducted flight test for the Australian Army with Army personnel also working within the unit. The flight test crew are long course trained at test pilot schools including the United States Air Force Test Pilot School, the United States Naval Test Pilot School, the Empire Test Pilots' School, the Ecole du personnel navigant d'essais et de reception and the National Test Pilot School. Context_6 : Bornvon Karman boundary conditions are periodic boundary conditions which impose the restriction that a wave function must be periodic on a certain Bravais lattice. (Named after Max Born and Theodore von Karman). This condition is often applied in solid state physics to model an ideal crystal. Born and von Karman Context_7 : The Spacecraft Magnetic Test Facility, also known historically as the Attitude Control Test Facility, is an experimental spacecraft test facility at the Goddard Space Flight Center in Greenbelt, Maryland, United States. It was built in 1966 to allow the evaluation of magnetic movement in manned and unmanned spacecraft, and for the precision calibration of magnetometers used in space flight. The building is constructed of non-magnetic materials and contains a magnetic coil system that allows the cancellation of the Earth's magnetic field. This unique building was designated a National Historic Landmark in 1985. Context_8 : Arnold Engineering Development Complex (AEDC), Arnold Engineering Development Center before July 2012, located at Arnold Air Force Base, Tennessee is a ground-based flight test facility operated by the Air Force Test Center. Context_9 : Gas kinetics is a science in the branch of fluid dynamics, concerned with the study of motion of gases and its effects on physical systems. Based on the principles of fluid mechanics and thermodynamics, gas dynamics arises from the studies of gas flows in transonic and supersonic flights. To distinguish itself from other sciences in fluid dynamics, the studies in gas dynamics are often defined with gases flowing around or within physical objects at speeds comparable to or exceed the speed of sound and causing a significant change in temperature and pressure. Some examples of these studies include but are not limited to: choked flows in nozzles and valves, shock waves around jets, aerodynamic heating on atmospheric reentry vehicles and flows of gas fuel within a jet engine. At the molecular level, gas dynamics is a study of the kinetic theory of gases, often leading to the study of gas diffusion, statistical mechanics, chemical thermodynamics and non-equilibrium thermodynamics. Gas dynamics is synonymous with aerodynamics when the gas field is air and the subject of study is flight. It is highly relevant in the design of aircraft and spacecraft and their respective propulsion systems. Context_10 : Henri Claude Benard, (25 October 1874 29 March 1939), French physicist, best known for his research on convection in liquids that now carries his name, Benard convection. In addition, the historical surveys of both Tokaty and von Karman both acknowledge that Benard studied the vortex shedding phenomenon later named the von Karman vortex street, prior to von Karman's own contributions. Benard specialized in experimental fluid dynamics, and the use of optical methods to study it. He was a faculty member at the universities at Lyon, Bordeaux, and finally the Sorbonne in Paris. fact_1 : The von Karman Gas Dynamics Facility at Arnold Engineering Development Complex, Arnold Air Force Base, Tennessee, provide aerothermal ground test simulations of hypersonic flight over a wide range of velocities and pressure altitudes. fact_2 : Arnold Engineering Development Complex (AEDC), Arnold Engineering Development Center before July 2012, located at Arnold Air Force Base, Tennessee is a ground-based flight test facility operated by the Air Force Test Center.
