The engine's name is a combination of the Roman numeral V, symbolizing the five original members of the International Aero Engines consortium, which was formed in 1983 to produce the V2500 engine. The 2500 represents the 25,000-pound-force (110 kN) produced by the original engine model, the V2500-A1.
IAE International Aero Engines AG is a Zürich -registered joint venture aeroengine manufacturing company. It was founded during 1983 specifically to develop an aircraft engine to address the 150-seat single aisle aircraft market, the V2500 turbofan.
The V2500 engine remains the quietest, most fuel efficient engine for the Airbus A320ceo family, with greater than 3% better fuel burn, the lowest emissions, and a significant payload-range advantage.
IAE manages engineering, sales, production, customer support and aftermarket services for the V2500 engine – one of the most successful commercial jet-engine programs in production today. The V2500 engine has 3 airframe applications; the Airbus A320 Family, the Boeing MD-90, and the Embraer KC390.
The IAE V2500 is a two-shaft turbofan engine specially designed for narrowbody aircraft. It is used to power a number of aircraft, including the Airbus A319, A320, and A321. A major advancement on this engine, the IAE V2500Select-One™, was introduced in September 2008.
