Saturn enterprise to produce gas turbine
engines for Russian Navy
JULY 14, 2014
Russia’s engine-building defense enterprise
Saturn will fully substitute marine gas turbine engines currently supplied by
Ukraine for Russian warships with its own output by 2017, the company’s press
office reported on Monday.
By 2017, the enterprise has undertaken to
switch to a full production cycle for the manufacture of M90FR engines (27,000
horsepower) and create power units on their basis, the CEO said.
The Saturn enterprise is also preparing a
basis for the trials of gas turbine engines for the Russian Navy. The
enterprise has already developed M75RU (7,000 horsepower) and M70FRU (14,000
horsepower) engines, the company’s press office said. Source: engineeringrussia.wordpress.com
NPO Saturn to shore up latest Russian
frigates
December 30, 2016
If the latest
reports coming out of Russia regarding the indigenously made gas
turbines are proved to be true, NPO Saturn might just save the day and shore up the
completion of the remaining Admiral Gorshkov-class(Project 22350) frigates in
the 2017-18 period as planned. While the Admiral Grigorovich-class is to
receive its first gas turbines in mid-2018 according to President of the United
Shipbuilding Corporation(OSK) Alexey Rakhmanov.
Troubles for two most ambitious blue water
ships – 22350 and 11356 – undertaken since the Soviet Union’s collapse, began
in 2014 as Ukrainian conflict ensued. Gas turbines and reduction gear
assemblies used in Admiral Gorshkov and Admiral Grigorovich class power plants
were made by the Ukrainian Zorya-Mashproekt “production complex”. Open
hostilities between Moscow and Kiev, spurred Ukraine’s refusal to deliver much
needed turbines to Russia.

DA91 Gas Turbine
First and second Project 22350 ships –
Admiral Gorshkov and Admiral Kasatonov – feature combined diesel and gas(CODAG)
M55R propulsion plants that consist of two Mashproekt made DA91(UTG15000+) gas turbines, two Russian Kolomna made 10D49 diesel engines and Mashproekt made
P055 reduction gear assembly. To come up with an indigenous gear reducers
alternative should not prove massively challenging for the Russians but gas
turbines require much greater investment, both in terms of finances and time
required for development and testing phase. Development of an indigenous gas
turbine for Project 22350 frigates commenced some years before the troubles in
Ukraine in 2014. Russian NPO Saturn company was commissioned to start work on
the M90FR turbine(main image), expecting to complete it in the 2017-18 time
frame. When Ukraine refused to supply the tribunes back in 2015, work on new
turbine was speeded up at the Kremlin’s behest. According to the latest
reports, advanced testing phase of the new M90FR turbine has already commenced
and first turbines are to be produced and installed on the third ship Admiral
Golovko in 2017. Total of between 8 and 15 ships of the Admiral Gorshkov-class
are planned for the Russian Navy in total. The fourth frigate – Admiral Isakov
– has been launched in Novemebr, 2013. All the ships are to be constructed at
St. Petersburg’s Severnoe shipyard, with the initial four to serve with
Russia’s Northern Fleet.

The other blue water casualty of the
Russo-Ukrainian fallout was Project 11356 Admiral Grigorovich-class frigate.
Initial three frigates – Admiral Grigorovich, Admiral Essen, Admiral Makarov –
feature combined gas and gas (COGAG) M7N1 propulsion plants. Those consist of
two DS71(UGT6000R) and DT59(UGT16000R) gas turbines each and R058, R063 and
R1063 gear reducers, all designed and made in Ukraine by Zorya-Mashproekt.
Consequently, prospect of completion of the remaining two Project 11356
frigates – Admiral Butakov and Admiral Istomin respectively – was rather
questionable. Thus, in October 2016 on sidelines of the BRICS Summit in Goa,
Russia and India formally agreed to transfer the remaining two ships to Indian
Navy. Latest rumour has it that Admiral Butakov and Admiral Istomin will, after
all, be completed for the Russian Navy as first planned.

DT59 Gas Turbine
Admiral Essen was to join Admiral Grigorovich
of the coast of Syria to supposedly test its weapon and battle systems in
combat. It has been reported that on 25 Novemebr, 2016, as it was preparing to
set sail for the Mediterranean, one of it’s shafts and propellers was damaged in
an accident due to human error.
DS71 Gas Turbine
Admiral Makarov is still in sea trials and
once commissioned is to join two other ships of the class over at the Russia’s
Black Sea fleet in Crimea. Remaining two frigates, just like three before them,
are being constructed at Yantar shipyard in the Russian enclave of Kaliningrad
and are at various stages of completion at present.
Why Russian Gas Turbine Engines Outclass
Ukrainian Ones
30 April 2017
Excerpt
Efficiency and lifetime of the new
Russian-made marine gas turbine engines will outclass foreign equivalents by
10-15%, said president Putin on Tuesday, April 25 at the opening ceremony of
the NPO Saturn’s new gas-turbine engine production facility. Most of these
engines made by Saturn (Rybinsk, Russia) are more efficient than their
Ukrainian counterparts: 36% vs 32%. However, comparing to Ukrainian products,
not every Russian propulsion plant enjoys the advantage mentioned by the
president. Below Mil.Today compared parameters of gas-turbine engines.
On April 25 in Rybinsk, the company
demonstrated two marine gas-turbine engines, M70FRU and M70FRU-2. In the table
below, Mil.Today compared parameters of these gas-turbine engines with
Ukrainian analogs and the M90FR.

Saturn-made engines M70FRU and M90FR were
made to substitute Ukrainian analogs DS71 and D090, respectively, a well-aware
insider told Mil.Today. In the main propulsion plant M27 mounted in the Project
11540 (Yastreb-class) corvette Yaroslav Mudryi, D090 engines are boosters while
DS71 are cruising ones. At that, the Russian engines have efficiency of 36%,
compared to 32% of Ukrainian powerplants.
Main propulsion plant of Project 11356
frigates is M7N1, using DS71 (known in Ukraine as UGT6000) as cruising engines,
and boosters are DT59 (UGT16000). Efficiency of the latter one is only 30%.

Frigates
M70FRU
Development – OAO NPO Saturn
Serial production – OAO NPO Saturn
M70FRU is a naval turboshaft engine with
14,000 h.p., developed especially for the Russian Navy and intended for use on
ships of all classes.
Dimensional
characteristics, power characteristics and rotational velocity of power
turbines allow to use the M70FRU engine in a whole range of older military
ships of various classes in Russia and abroad.
Availability
of versions working with gas fuel allow to use M70FRU as a drive for electric
generators and gas compressors (superchargers) on all civil naval and sea-side
object which have access to gas fuel (floating power stations, sea rigs,
sea-port plats etc)
M75RU
Development – OAO NPO Saturn
Serial production – OAO NPO Saturn.
M75RU
is a naval turboshaft engine with 7,000 h.p., developed specially for the
Russian Navy. The first tests of the trial GTD M75RU, which became the first
Russian naval turboshaft engine, took place in 2003. The decree of the state
trial board certifying the GTD M75RU with the maximum of 7,000 h.p. was signed
on the 25th November 2006. A series of engines are planned for development on
the basis of M75RU specially for the Russian Navy, Border Control Services and
civil ships.
