Il devrait y avoir des PIP pour le Sam146 ...
J'suis pas russophile je n'arrive pas à savoir si ça sera pour 2014 ou 2016

NPO Saturn, a subsidiary of the United Engine Corporation (UEC), is planning to produce 62 PowerJet SaM146 engines for Sukhoi Superjet 100 (SSJ 100) aircraft, according to what the company’s general designer Yuriy Shmotin said at the International Engine Building Forum held in Moscow from April 19 to 21. The Russian company produces these engine units in the town of Rybinsk, in cooperation with its French partner Safran, in the framework of a joint venture called PowerJet. Earlier this year, the company assembled the 200th series-production engine of this type. In 2015, NPO Saturn produced 39 engines.

In addition to the MC-21, UEC is involved in another major commercial engine programme. Its subsidiary NPO Saturn partnered with Snecma 20 years ago to develop a new engine to power the Superjet. The joint venture, PowerJet International, is integrating a new engine core derived from the Snecma M88 and a low-pressure section developed by Saturn.
To support a series of improvements launched by Sukhoi Civil Aircraft (SCAC), PowerJet has developed and certificated three engine modifications that raise total thrust of the SaM146 by 5%. An additional 2.5% thrust improvement is possible, UEC says, with no expensive hardware changes.
"It could be achieved by just regulating the FADEC software and it doesn't require any changes in the engine's hardware, which means that there is no need for any additional trials," UEC says. "The [higher-thrust] engine remains in line with its certification basis."
