UEC supplied "Severnaya Verf" with a diesel-gas turbine unit М55Р for the frigate "Admiral Isakov"

The Severnaya Verf shipyard, which is building Project 22350 frigates, has received another Russian-made M55R diesel-gas turbine unit. The unit is intended for the frigate "Admiral fleet Isakov of the Soviet Union, "the press service of Rostec reported.

As stated in the holding, this is the fourth M55R unit supplied by Severnaya Verf, in general, and the second for Admiral Isakov. The first was delivered in early July. The first delivery of DGTA-M55R within the framework of import substitution of Ukrainian power plants was carried out in November last year. Then Severnaya Verf received a kit for the frigate Admiral Golovko.

At the end of June this year, Severnaya Verf signed a contract for the supply of four diesel-gas turbine M55R units for the frigates Admiral Yumashev and Admiral Spiridonov under construction. Thus, taking into account the new contract, Russian power plants DGTA-M55R will be equipped with six frigates: Admiral Golovko, Admiral Isakov, Admiral Amelko, Admiral Chichagov, Admiral Yumashev and Admiral Spiridonov. The lead and the first serial frigates "Admiral Gorshkov" and "Admiral Kasatonov" received units produced by "Zorya" - "Mashproekt" (Nikolaev, Ukraine).

In addition to the M55FR gas turbine engine with a maximum power of 90 horsepower, the DGTA-M27R includes a 500D10 diesel engine with a power of 49 horsepower, a PO5200R gearbox and control systems.

And what about the "Star-Reducer"? In the UEC already?

[jonht]

I read this, and the turbines began to be assembled faster, I wonder if the problems with assembling and testing the gearboxes were solved. From the latest news on them, here to see prices on the site, it was the gearbox that slowed down the assembly and transfer of the DGTA-M55R

If the delivery is already complete with a gearbox, then we have decided.

A pleasant message for a Russian's ear and not very much for our enemies.

I, of course, am not a specialist in gearboxes, although I can distinguish a worm gear from an operational amplifier, but I have no idea how the unit for adding power from such different engines works. They write that it is very difficult.
Isn't it easier to put an electric drive on the propellers?
The technology has been perfected for a hundred years, the engines are produced without problems, judging by the submarines.
What's in the way? A stereotype of traditions or are there any physical contraindications?

[bayard]

On these gearboxes, the torque from the diesel engine and the turbine does not add up, they work one by one on one shaft - a diesel engine on economic speed, a turbine for full speed.

There is a big loss of power on double conversion. Anyone who does not mind fuel and is ready to install more powerful engines does this. An electric transmission is also used to reduce noise, on the same submarines - there is a reactor, it has more than enough power.

From the point of view of mechanics - of course. But there are pitfalls. DC motors are problematic. But variable - you need high quality voltage and frequency. Especially for the "synchronization" of the frequency, very high-quality frequency converters are needed, the production technologies of which in Russia, if I am not mistaken, are not available at the moment.

An example of the use of this technology is destroyers type 45 (the same Defender). Rolls-Royce and General Electric are still tinkering with this setup. So far, this is the main headache on all Type 45 destroyers. For example, the unit completely refused to work in warm latitudes.

How then do our submarines work? Icebreakers?

Diesel - there is not such a capacity. And the diesel itself, on the shaft. In atomic ones, too, on the shaft, only auxiliary ones on electric motors.

Quote: Jacket in stock

Icebreakers?

You probably meant diesel-electric. It is difficult to compare "peaceful" and military equipment here. Warships go completely differently, the power is different. Don't forget, destroyer frigates have both diesel and turbines. Synchronizing voltage and frequency is a tricky thing. Power and high-current electrics and electronics are generally "their own" science

I understand it. Okay, Belaz and diesel locomotives, there are less power, But I don't understand what the fundamental difference is between a frigate and an icebreaker. diesel-electric ships have been building for 100 years.

But I don't understand what the fundamental difference is between a frigate and an icebreaker.

Combat ships operate in a completely different way: they accelerate, quickly reach maximum power, etc. In addition, there are limitations in the volumes for the installation of equipment, strict requirements for the survivability of the propulsion device. Let's not forget about the possible impact of EMP.

Yes, I agree with you, these technologies are the future for the combat fleet and they need to be developed. But, if power electronics as such does not develop in Russia, then the installation for the development of such propellers for the Navy will become simply "golden".

I am glad that Russian shipbuilders were able to get rid of foreign dependence in the construction of power plants. I tried to find something about the performance characteristics, but only this was possible:

DGTA M55R in terms of a set of characteristics, it is currently the best power plant of all those used on surface ships of the Russian Navy and is not inferior to similar units used on the ships of the naval forces of the NATO countries... The creation of DGTA M55R was carried out in close cooperation with Severnoye PKB JSC. Tests of the unit assembled with a gearbox, diesel engine and local control systems were carried out in the assembly and testing complex of ship gas turbine engines and gas turbine units at one of the enterprises of the UEC.

This suggests that sea trials are one of the main stages of commissioning. And we have no practical observations (working experience) on the operation of the units.
I really want the declared characteristics to be at the proper height.

This unit took so long to give birth because bench tests are carried out with all the proper loads. And they, as a rule, exceed those that he experiences in the conditions of the ship.

Well, the timing is generally a big problem, if each mechanism is tested as long as it should work, we would not even sail on steamers. Therefore, modeling is applied that simulates resource loads.

I can not say anything about ship units, since I have never been a crew, although I wore a naval uniform for half my life (naval aviation). Therefore, from the experience of operating aircraft engines, I can say that according to the results of factory tests, some kind of resource is assigned, after which the engine is removed, a new resource is investigated and assigned (with ships, it is probably done in a different way, without removal). Only during my service life of the NK-12MV engines on our Tu-95RTs was increased from 500 hours to 1500 hours. And this without any significant changes in the design.

I can not say anything about the ship assemblies

And I could not find anything on the performance characteristics of the units and their comparative characteristics with foreign counterparts. I cross out the Chinese and Ukrainian ones at once. It is important for me to find out whether something remarkable has really been created in Russia, or if these are just regular “approximations” to “Wishlist”.
How many we had to read, that created "analogs will humble", but in fact - now a running cart, then a goat ...
I do not want to be deceived and I want to rejoice, without subsequent disappointments.
But, based on the available data, I can only assume that the final result will be (can be summed up) only by sea trials.

The lead time for admirals allows us to hope for the best.

It’s interesting - why divorce secrets with the test site of ship-borne gas turbine engines, if in the spring of 2017 the assembly and testing complex of ship gas turbine units, created by the UEC under contracts with the Ministry of Industry and Trade of Russia and the State Corporation Rostec on the basis of Rybinsk PJSC NPO Saturn, was demonstrated by GDP, and Was this visit covered in the media?

Stand No. 1 is intended for testing gas turbine engines M70FRU, M70FRU-2, M70FRU-R and units based on them with a capacity of up to 15 MW.

The design of test bench No. 2 for testing GTEs with a capacity of up to 40 MW is also universal and provides testing of a unit consisting of two simultaneously operating M90FR GTEs and one diesel engine with power output through a reducer-adder.

Usually, secrecy is induced if the performance characteristics are so strikingly different from world analogues (when, in fact, “analogs are dying”), or when something mediocre in reality is “analogous”.
It is stupidity to underestimate the merits and characteristics of what can bring money to the budget.

[Elturisto]

Because the tests were carried out in Nikolaev (Ukraine), there are no turbines or gearboxes in the Russian Federation, as well as stands for complex testing of installations.

United Engine Corporation Rostec delivered to the Severnaya Verf Shipyard in St. Petersburg a diesel-gas turbine unit (DGTA) М55Р for the left side shafting line of the third serial frigate of project 22350 "Admiral of the Fleet of the Soviet Union Isakov".

I do not understand anything about this, but there is a personal impression that a very compact installation is obtained (in comparison with the size of the ship).

UEC Saturn, together with Rostec, liquidly obgadilos once again. Gas turbines and a reducer Nikolayevskie :) Therefore, they write that they have installed the unit in the assembly. There are only Kolomna diesel engines, and even then all the times of the USSR, thanks to the damned Scoop, they are still efficiently sawing .. ...
