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), and the McDonnell Douglas MD-90.[1] International Aero Engines is a consortium backed by four aero-engine manufacturers, formed in 1983 to produce the engine. FAA flight certification for the V2500 was granted in 1988.

[edit] Development
Rolls-Royce based the HP compressor on a scale-up of the RC34B eight stage research unit used in the RB401-06 Demonstrator Engine, but with a zero-stage added at the front and a tenth stage added to the rear. Pratt & Whitney developed the combustor and the 2-stage air-cooled HP turbine, while the Japanese companies provided the LP compression system. MTU were responsible for the 5-stage LP turbine.
The 4,000th V2500 engine was delivered to the Brazilian flag carrier TAM and installed on the 4,000th Airbus A320-family aircraft (an A-319).[2][3]
[edit] Variants
[edit] V2500-A1
The original version to enter service with Cyprus Airways.
[edit] V2533-A5
A fourth booster stage was introduced into the engine basic configuration to increase core flow. This, together with a fan diameter/airflow increase, helped to increase the thrust to 33,000 lbf (147 kN) thrust, to meet the requirements of the larger Airbus A321-200.[citation needed]
[edit] Derated versions
A number of derated, Stage 4 noise compliant engines have been produced from the -A5 configuration, including:
- The 23,500 lbf (105 kN) thrust V2524-A5 for the Airbus A319
- The 27,000 lbf (120 kN) thrust V2527-A5 for the Airbus A320
- The 28,000 lbf (120 kN) thrust V2528-D5 for the McDonnell Douglas MD-90-30.
[edit] V2500SelectOne
On October 10, 2005, IAE announced the launch of the V2500SelectOne with a sale to IndiGo Airlines to power 100 A320 series aircraft. The V2500SelectOne is a combination performance improvement package and aftermarket agreement. In February 2009, Pratt & Whitney upgraded the first V2500-A5 to the SelectOne Retrofit standard; the engine was owned by US Airways and had been in use since 1998.[4]
[edit] Applications
- Airbus A320 family (excluding A318, and the neos)
- Embraer KC-390
- McDonnell Douglas MD-90
