Question: Who created the National Gas Turbine Establishment and was credited with inventing the turbujeet engine?

full_context: Document 1: Power Jets: Power Jets was a British company set up by Frank Whittle for the purpose of designing and manufacturing jet engines. The company was nationalised in 1944, and evolved into the National Gas Turbine Establishment.
Document 2: National Gas Turbine Establishment: The National Gas Turbine Establishment (NGTE Pyestock) in Fleet, part of the Royal Aircraft Establishment (RAE), was the prime site in the UK for design and development of gas turbine and jet engines. It was created by merging the design teams of Frank Whittle's Power Jets and the RAE turbine development team run by Hayne Constant. NGTE spent most of its lifetime as a testing and development centre, both for experimental developments and to support commercial engine companies.
Document 3: International Aero Engines: IAE International Aero Engines AG is a Zürich-registered joint venture manufacturing company founded in 1983 to develop an aircraft engine to address the 150-seat single aisle aircraft market. The collaboration, between four of the world’s leading aero engine manufacturers, produced the V2500 – the second most successful commercial jet engine program in production today in terms of volume, and the third most successful commercial jet engine program in aviation history.
Document 4: Von Karman Gas Dynamics Facility: 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.
Document 5: PowerJet: PowerJet is a Franco-Russian 50-50 joint venture created in 2004 by aeronautical engine manufacturers Snecma (Safran) and NPO Saturn. The company is in charge of the SaM146 program – the sole powerplant for the Sukhoi Superjet 100 airliner – including design, production, marketing and after-sales support. It delivers a complete propulsion system, comprising engine, nacelle and equipment.
Document 6: John Ambrose Fleming: Sir John Ambrose Fleming FRS (29 November 1849 – 18 April 1945) was a British electrical engineer and physicist. He is known for inventing the first thermionic valve or vacuum tube. He is also famous for the left hand rule (for electric motors). He was born the eldest of seven children of James Fleming DD (died 1879), a Congregational minister, and his wife, Mary Ann, at Lancaster, Lancashire and baptised on 11 February 1850.
Document 7: Geoffrey de Havilland: Captain Sir Geoffrey de Havilland (27 July 1882 – 21 May 1965) was a British aviation pioneer and aircraft engineer. His Mosquito has been considered the most versatile warplane ever built, and his Comet was the first jet airliner to go into production.
Document 8: Aviadvigatel: Aviadvigatel OJSC (Russian: ОАО "Авиадвигатель", lit. Aeroengine) is a developer and builder of aeroengine like Turbofan and Gas Turbine based on Perm Engine Plant , notably for the Ilyushin Il-76MF, Ilyushin Il-96, Tupolev Tu-204, Tupolev Tu-214. It also designs and builds high-efficiency gas turbine units for electric power stations and for gas pumping plants. The company has it backgrounds in the Experimental Design Bureau-19 plant, set up to manufacture aircraft engines.
Document 9: Ernst Heinkel: Dr. Ernst Heinkel (January 24, 1888 – January 30, 1958) was a German aircraft designer, manufacturer, Wehrwirtschaftsführer in the Third Reich, and member of the Nazi party. His company Heinkel Flugzeugwerke produced the Heinkel He 178, the world's first turbojet aircraft and jet plane, and the Heinkel He 176, the first rocket aircraft. He was awarded the German National Prize for Art and Science in 1938.
Document 10: Engine Alliance: The Engine Alliance (EA) is an American aircraft engine manufacturer based in East Hartford, Connecticut. The company is a 50/50 joint venture between GE Aviation, a subsidiary of General Electric, and Pratt & Whitney, a subsidiary of United Technologies. Engine Alliance was established in August 1996 to develop, manufacture, sell, and support a family of modern technology aircraft engines for new high-capacity, long-range aircraft.
Document 11: Lucien Servanty: Lucien Servanty (born in 1909 in Paris, died 7 October 1973 in Toulouse) was a French aeronautical engineer. A graduate from the Ecole des Arts et Métiers, he joined Breguet in 1937, then worked at the SNCASO, where he was involved in the redesign of late variants of the Bloch MB.150 line. During World War II, he designed the SO.6000 Triton, France's first jet aircraft. But Lucien Servanty is probably best remembered today for being one of the main engineers behind Concorde (fastest general, public usage plane ever produced).
Document 12: Royal Aircraft Factory F.E.1: The Royal Aircraft Factory F.E.1 was designed and built in 1910 by the pioneer designer Geoffrey de Havilland. He used it to teach himself to fly during late 1910. After De Havilland was appointed assistant designer and test pilot at Army Balloon Factory at Farnborough (later the Royal Aircraft Factory) in December 1910 the War Office bought the aircraft for £400. the aircraft was given the designation F.E.1 ("Farman Experimental")
Document 13: Honeywell AGT1500: The Honeywell AGT1500 is a gas turbine engine. It is the main powerplant of the M1 Abrams series of tanks. The engine was originally designed and produced by the Lycoming Turbine Engine Division in the Stratford Army Engine Plant. In 1995, production was moved to the Anniston Army Depot in Anniston, Alabama after the Stratford Army Engine Plant was shut down.
Document 14: GT 101: The GT 101 was a turboshaft-type gas turbine engine developed from the BMW 003 aviation engine, that was considered for installation in Nazi Germany's Panther tank. The German Army's development division, the "Heereswaffenamt" (Army Ordnance Board), studied a number of gas turbine engines for use in tanks starting in mid-1944. Although none of these was fitted operationally, the GT 101 (GT for "Gas Turbine") reached a production quality stage of development. Several designs were produced over the lifetime of the program, including the GT 102 and GT 103.
Document 15: Frank Whittle: Air Commodore Sir Frank Whittle {'1': ", '2': ", '3': ", '4': "} (1 June 1907 – 9 August 1996) was an English Royal Air Force (RAF) engineer air officer. He is credited with single-handedly inventing the turbojet engine. A patent was submitted by Maxime Guillaume in 1921 for a similar invention; however, this was technically unfeasible at the time. Whittle's jet engines were developed some years earlier than those of Germany's Hans von Ohain who was the designer of the first "operational" turbojet engine.
ground_truth: Frank Whittle
