The joint venture was formally established during 1981, it became a part of the larger International Aero Engines (IAE) consortium in the following year.
[citation needed] Around 1982, the consortium's attention was redirected towards the co-development of a more advanced engine in the 25000lbf thrust class for the 150 seater market.
Pratt & Whitney, MTU and FiatAvio joined the consortium, by then named International Aero Engines, shortly afterwards.
MTU Aero Engines were responsible for the 5-stage low pressure turbine, while Fiat Avio designed the gearbox.
[3] In the decades since its establishment, the consortium has been involved in the development of numerous civil aero engines via international collaborations.
