Question: International Aero Engines produced what two-shaft engine for the Airbus A320?
Context: The Bristol Aeroplane Company, originally the British and Colonial Aeroplane Company, was both one of the first and one of the most important British aviation companies, designing and manufacturing both airframes and aircraft engines. Notable aircraft produced by the company include the 'Boxkite', the Bristol Fighter, the Bulldog, the Blenheim, the Beaufighter, and the Britannia, and much of the preliminary work which led to the Concorde was carried out by the company.  In 1956 its major operations were split into Bristol Aircraft and Bristol Aero Engines.  In 1959, Bristol Aircraft merged with several major British aircraft companies to form the British Aircraft Corporation (BAC) and Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley. The Airbus A321 is a member of the Airbus A320 family of short- to medium-range, narrow-body, commercial passenger twin-engine jet airliners manufactured by Airbus.  It was the first derivative of the baseline Airbus A320 aircraft, and carries up to 236 passengers with a maximum range of 3200 nmi .  Final assembly of the aircraft takes place in Hamburg, Germany or Mobile, Alabama in the US. The IAE V2500 is a two-shaft high-bypass turbofan engine which powers the Airbus A320 family (A320, A321, A319 and the Airbus Corporate Jet), the McDonnell Douglas MD-90, and the Embraer KC-390. The aerospace industry of the United Kingdom is the fourth-largest national aerospace industry in the world and the third largest in Europe, with a global market share of 6.4% in 2016.  In 2013, the industry employed 84,000 people.  Domestic companies with a large presence in the British aerospace industry include BAE Systems (the world's third-largest defence contractor), Britten-Norman, Cobham, GKN, Hybrid Air Vehicles, Meggitt, QinetiQ, Rolls Royce (the world's second-largest maker of defence aero engines) and Ultra Electronics.  Foreign companies with a major presence include Boeing, Bombardier, Airbus (including its Astrium, Cassidian and Surrey Satellite Technology subsidiaries), Leonardo (including its AgustaWestland and Selex ES subsidiaries), General Electric (including its GE Aviation Systems subsidiary), Lockheed Martin, MBDA (37.5% owned by BAE Systems), Safran (including its Messier-Dowty and Turbomeca subsidiaries) and Thales Group (including its UK-based Thales Air Defence, Thales Avionics and Thales Optronics subsidiaries).  Current manned aircraft in which the British aerospace industry has a major role include the AgustaWestland AW101, AgustaWestland AW159, Airbus A320 family, Airbus A330, Airbus A340, Airbus A380, Airbus A400M, BAE Hawk, Boeing 767, Boeing 777, Boeing 787, Bombardier CRJ700, Bombardier CSeries, Bombardier Learjet 85, Britten-Norman Defender, Britten-Norman Islander, Eurofighter Typhoon, Hawker 800, Lockheed Martin C-130J Super Hercules and Lockheed Martin F-35 Lightning II.  Current unmanned aerial vehicles in which the British aerospace industry has a major role include BAE Taranis, HAV 304 Airlander 10, QinetiQ Zephyr and Watchkeeper WK450. The McDonnell Douglas MD-90 is a twin-engine, short- to medium-range, single-aisle commercial jet airliner.  The MD-90 was developed from the MD-80 series.  Differences from the MD-80 include more fuel-efficient International Aero Engines V2500 engines and a longer fuselage.  The MD-90 has a seating capacity of up to 172 passengers and was introduced into service with Delta Air Lines in 1995. MTU Aero Engines AG is a German aircraft engine manufacturer.  MTU develops, manufactures and provides service support for military and civil aircraft engines.  MTU Aero Engines was formerly known as MTU München. TAM Airlines Flight 3054 (JJ3054/TAM3054) was an Airbus A320-233, registration PR-MBK, on a scheduled domestic passenger flight from Porto Alegre to São Paulo, Brazil.  On July 17, 2007, the Airbus A320 overran runway 35L at São Paulo during moderate rain and crashed into a nearby TAM Express warehouse adjacent to a Shell filling station.  All 187 passengers and crew aboard the Airbus A320 died, along with 12 people on the ground.  It surpassed Gol Transportes Aéreos Flight 1907 as the deadliest air disaster in Brazilian territory, and remains the deadliest aviation accident involving an Airbus A320 proper worldwide.  It was also the deadliest accident involving an aircraft of the A320 family at the time, which was later surpassed by the bombing of Metrojet Flight 9268, an A321-231, which crashed in Egypt in October 2015 with 224 fatalities. Honda Aero, Inc. (HAI), a wholly owned subsidiary of Honda Motor Co., Ltd., is headquartered in Burlington, North Carolina near the Burlington - Alamance Regional Airport.  The Burlington facility will serve as the primary production location for engines developed and marketed by GE Honda Aero Engines, LLC (a joint venture between Honda Aero and GE), beginning with the GE Honda HF120 turbofan engine.  Development of the facility represents a $27 million capital expenditure by Honda, bringing the company's total North American capital investment to more than $9 billion.  Production began with the GE Honda Aero Engine HF120 on March 17, 2015. 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. The IAE V2500 SuperFan was a design study for a high-bypass geared turbofan derived from the IAE V2500.  It was offered as the primary engine option for the Airbus A340 in January 1987.  Although several customers signed preliminary contracts for this variant, the International Aero Engines board decided in April 1987 to stop the development of the SuperFan, which forced Airbus to partly re-design the A340.
Answer: IAE V2500
