The SaM146 engine: 100 thousand hours on wing

Site news 7.07.2014

July 7, 2014, Rybinsk. - As of July 1, 2014, the total time on wing generated by the fleet of the SaM146 engines in revenue service powering the Sukhoi Superjet 100 aircraft has exceeded 100 000 flight hours.
The main reliability indicators of the engine operation meet the requirements of the international standards and world practice of operating modern aircraft engines. In particular, the engines dispatch ratio ensuring the timely departure of an aircraft is estimated to be 99.96 %.
As of today, the airlines have already received 35 SSJ100 in total; the current flight network comprises around 70 airports in 23 different states. The main customers operating the SSJ100 aircraft powered by the SaM146 engines are the Russian companies such as Aeroflot - Russian Airlines, Gazpromavia, Moskoviya, Yakutiya, Tsentr-Yug, as well as a number of foreign airlines including InterJet (Mexico), Sky Aviation (Indonesia) and Lao Central Airlines (Laos). Since June 2014 the SSJ100 are also delivered to YuTair-Express. The airline has ordered 6 SSJ100 aircraft + another 18 aircraft on option.
Some facts:
The SaM146 propulsion system was designed by NPO Saturn in collaboration with a French company Snecma and represents an integrated power plant (incorporating the engine, the nacelle and the engine accessories) purpose-designed for application on regional/medium-range new-generation aircraft.
The SaM146 program is built on the principals of a strategic, risk- and revenue-sharing partnership with parity in every respect of activity. NPO Saturn is in charge of the design of low-pressure components of the engine, their manufacturing and conducting of special tests of new parts; it’s also in charge of the engine assembly, preparation and conducting of the entire range of ground tests and engine delivery to the customer while Snecma is in charge of the design and fabrication of the high-pressure engine components, general design supervision and engine systems integration; Snecma is also in charge of conducting flight tests of the power plant and integration of the propulsion system with the airframe.
The SaM146 is the first Russian-made propulsion system having received an internationally recognized EASA type certificate. The first application of the SaM146 power plant is the Sukhoi Superjet 100 aircraft family designed by Sukhoi Civil Aircraft Company (a 100% subsidiary of Sukhoi Holding Company in partnership with Alenia (Italy).
The engine has materialized and been fully certified. All of its design parameters have been achieved in operation. A number of post-certification activities have been planned and are now underway in relation with engine life tests, performance optimization activities, weight decrease and conducting of specific design engineering actions aimed at improving the engine performance and in-service reliability.
The NPO Saturn Research and Production Association (OJSC) is an engine-building company specialized in the design and development, production and after-market support of gas turbine engines for military and civil aviation, naval ships and power-generating plants and gas-pumping units.
