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.[2]

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[edit]

A Mihin Lanka Airbus A320 powered by IAE V2500 engines.

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).[3][4]

Variants[edit]

V2533-A5[edit]

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] The vast majority of V2500s are A5. The maintenance, repair, and operations market for V2500 is close to US$3 billion as of 2015.[1]

Derated versions[edit]

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

V2500SelectOne[edit]

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[edit]

On March 15, 2011, IAE announced an upgrade option of V2500 SelectOne Engines to the SelectTwo Program.[5] It offers 0.58% reduced fuel consumption due to a software-upgrade and a turbine blade coating called ErCoat,[1] and is available since 2013 for the V2500-A5 variants.
