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.

International Aero Engines is a consortium backed by four aero-engine manufacturers, formed in 1983 to produce the engine. FAA type certification for the V2500 was granted in 1988.

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 Aero Engine Corporation 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 A319).

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. The vast majority of V2500s are A5. The maintenance, repair, and operations market for V2500 is close to US$3 billion as of 2015.

Derated versions

A number of derated, Stage 4 noise compliant engines have been produced from the -A5 configuration, including:

V2500SelectOne

On October 10, 2005, IAE announced the launch of the V2500Select—later called 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.

V2500SelectTwo

On March 15, 2011, IAE announced an upgrade option of V2500 SelectOne Engines to the SelectTwo Program. It offers 0.58% reduced fuel consumption due to a software-upgrade and a turbine blade coating called ErCoat, and is available since 2013 for the V2500-A5 variants.
