IAE V2500

The IAE V2500 is a two-shaft high-bypass turbofan built by International Aero Engines, a consortium formed in 1983 whose five original members the Roman numeral V in the name represents. It powers the Airbus A320 family, excluding the A318, along with the McDonnell Douglas MD-90 and the Embraer C-390 Millennium. The 2500 in the name refers to the 25,000 pounds-force (110 kN) of thrust of the original V2500-A1, and FAA type certification was granted in 1988. Rolls-Royce based the ten-stage high-pressure compressor on earlier runs in the RB401 and RJ500, while Pratt and Whitney developed the combustor and high-pressure turbine, the Japanese Aero Engine Corporation provided the low-pressure compression system, MTU the low-pressure turbine and Fiat Avio the gearbox. Variants include the V2500-A5, D5 and E5 and the SelectOne and SelectTwo upgrades.
