International Aero Engines
International Aero Engines (IAE ) is a consortium of five companies originally with the aim to develop the V2500 a new engine in the medium thrust class for the Airbus A320 family.
The name of the product V2500 symbolizes on the one hand the Roman numeral 5 for the number of founding members, as well as 2500 lbf thrust class for the target of 25,000. However, as with many other engines, the thrust class has now increased to 33,000 lbf, the original variant ( A1) with only 25,000 lbf is no longer produced. Founding members in 1983 were Rolls- Royce, Pratt & Whitney, the Japanese Aero Engines Corporation JAEC, MTU Aero Engines and Fiat Avio. On the basis of financial turmoil, the Fiat Group has separated in the 1990s from their shares and these were ever taken over half of Rolls- Royce and Pratt & Whitney. The company is FiatAvio but still connected as a supplier of parts to the project. On 12 October 2011, Rolls- Royce announced its shares in IAE for $ 1.5 billion to Pratt & Whitney to sell. Rolls- Royce but retains responsibility for its corresponding components on the engine and also for 50% of the final assembly.
The European final assembly of the entire engine was relocated in 2005 by Rolls- Royce in Derby at the German subsidiary to Dahlewitz near Berlin. In addition, at Pratt & Whitney in Middletown, CT the second final assembly line will continue.
The engines come to the A320 family in thrust versions of 110 kN to 150 kN applied ( versions A1 and A5/A5Select ) and compete here with the CFM56 by the manufacturer consortium CFMI. At the McDonnell Douglas MD -90 was - up to their end of production in 2000 - the V2500 -D5 the sole engine.
On the A320 family, the V2500 was at 42.3 % of all aircraft ordered selected as a drive.
Sales with Stand: September 2004
In 2003 IAE achieved a market share of approximately 87 % in new orders for the A320 family. In the order books were at this time more than 5,000 engines, of which the 3000 engine was delivered in December 2006, with the following breakdown. :
Meanwhile, working with the Select or SelectOne programs on a refinement of the engines with the goal of reducing the consumption and longer service life. When announced in March 2011 in response to the PW1100G SelectTwo program further fuel savings of 0.58 % to be achieved at the beginning in 2013 the available engines by software changes.
