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.

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]


Airbus A320 Nacelle


First entered service with Adria Airways.


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:

  • 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 25,000 lbf (110 kN) thrust V2525-D5 for the McDonnell Douglas MD-90-30. Engine Turbine and Accessory on the side instead of bottom to accommodate side mount. Also has an option in the cockpit to add 3K extra lbf in case of Hot and High conditions
  • The 33,000 lbf (150 kN) thrust V2533-A5 for the Airbus A321
  • The 31,330 lbf (139.4 kN) thrust V2535-E5 for the Embraer KC-390


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.


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.
