Nouveau moteur pour la famille des su-27

[warbird2000]

Russia’s United Engine Corporation (UEC) a démarré le développement d'un nouveau moteur pour la famille des su-27 / 30 / 35

Russia’s United Engine Corporation (UEC) – the holding company that controls all aero-engine design bureaus and production plants in the country – has initiated the development of a common advanced afterburning turbofan suitable for installation on the entire production line of Su-27/30/35 (Flanker) fighters

Also intended to be offered to export customers, this derivative engine utilises the baseline design of the NPO Saturn’s AL-41F-1S (also known as Product 117S), and is mainly being targeted as a replacement of older-generation AL-31Fs and AL-31FPs. The technologies used promise to reduce life-cycle costs, thanks to the extended time between overhauls (TBO) and longer service life, while also offering reduced production costs, lower specific fuel consumption and a significantly higher thrust rating. This combination is being regarded as a cost-effective, performance-boosting factor for the increasingly heavier new Flanker derivatives, enabling more range and payload in addition to better manoeuvrability and shorter take-off run.
