Russia starts its own serial production of PO55 gearboxes, previously produced in Ukraine. According to the press service of the PJSC “star”, gearboxes for the first domestic power plant of the project frigate 22350 successfully tested and found ready for serial production.

As explained, the new gearbox was tested as part of a diesel-gas turbine unit, developed and manufactured by NPO “Saturn” (“ODK-Saturn”). The press service specified, that a large-scale project to master the production of a new type of PO55 gearboxes began in 2017 year.

By order of the President of the Russian Federation, the plant was tasked with mastering the production of new heavy gearboxes as soon as possible., including for the project 22350. Previously, gearboxes of such power were never produced in the Russian Federation.. This is the first and very difficult project. We managed to deal with him, and now we can meet the needs of the Russian fleet for this type of transmission

The gearbox provides full forward power when the turbine engine is running 27200 hp, when the diesel engine is running - 5069 hp; its weight is about 40 tonnes. The design uses only domestic components.

The next step will be the installation of the power plant on the “Northern shipyard” ship, at the same time PAO “star” conducts the manufacture of two more products for the next frigate
– It said in a statement.

According to a blog bmpd, the first set of fully Russian-made PO55 gearboxes for the DGTA-M55R diesel-gas turbine unit will be installed on the fourth frigate of the project 22350 “Admiral of the Fleet of the Soviet Union Isakov”, under construction on “Northern shipyard”. The next set will be made for the third frigate of the project 22350 “Admiral Golovko”. This is due to the peculiarity of the renewal of contracts for the production of gearboxes at PJSC “star” after the Ukrainian crisis 2014 of the year.
