Design and development

The SaM146 is the outcome of a Franco-Russian joint venture between Safran Aircraft Engines of France and United Engine Corporation (UEC) of Russia. In the joint venture, Saturn, an engine design and manufacturing subsidiary of UEC is responsible for the design and manufacturing of the cold section which includes the fan, the low-pressure turbine and the low-pressure compressor, as well as for the general assembly and testing of the SaM146 engine. Conversely, the area of responsibility for Safran Aircraft Engines which is represented by its subsidiary, Snecma, covers the design and manufacture of the engine core or hot-section - this includes the development of high-pressure compressor, high-pressure turbine, a combustion chamber, an accessory gearbox, electronic engine control and power plant integration. The SaM146 engine and its manufacturing process are certified to the EASA and IAC AR regulations. Deliveries and all after-sales services on the SaM146 are performed by PowerJet. The SaM146 core design is mainly based on the

By August 2017, the 300th Russian-French SaM146 engine for the Sukhoi Superjet 100 (SSJ100) aircraft has been assembled at UEC – Saturn (United Engine Corporation) and delivered to Sukhoi Civil Aircraft Company. To date, the SaM146 engine fleet has logged over 700,000 flight hours. In 2018 due to SaM146 problems 2 companies scrapped SSJ100 from their fleet: Red Wings and Yakutia.

Poor SSJ100 reliability rate occurs due to a malfunction of Sam-146 engine's combustor after 2000-4000 hours. The manufacturer is said to be working on modifications to the combuster in a bid to address the issues.
