Domestic production of marine engines for Russian Navy

Russia has recreated the production of gas turbine engines for combat ships
https://regnum.ru/news/economy/2630696.html

It is one thing to say they are ready to make them, it is another to actually make the number you need, while also providing a source for space parts and components to repair and maintain existing engines as well as new engines fitted to ships.

pretty sure they in "pilot build" with gas turbines
so they are getting very close to mass production …. with "less skilled" employees

but you have to remember the entire Russian gas turbine industry is under a lot of pressure
and the manufacturers of the high temperature cores …. have a lot of heat on them …. literally

it is truly remarkable what they have done to date …. remarkable people

diesels ? …. no idea ….
to be honest …. I'd be focussed on gas turbines with electric backup anyway ….

all navies have the same problem …. cost of operation
and LNG driven gas turbine + electric is a no-brainer for Russia you would think ….

most of the US Navy runs gas turbines … as the USA oil is not suitable strategically for diesel …. too light
Russia should think the same way … strategically …. and its cheaper anyway

as I keep saying …. that 20386 corvette is a really really really interesting boat ….
it is the future …. gas turbine / electric ….. multi-functional …. container modularity

Yes but generally the electric part of the hybrid system is obtained not by the das turbines but by charging it with diesel generators. Lot of CODLAG or CODLOG, latest proposal are toward get it in full: diesels for bothcruise propulsion and electrical production, Gas for speed with the possibility of combine them all together when you want to go really fast.

I've been trying to fully understand it all

my understanding is the RAN are the world leaders in hybrid drives
so you'd have to expect that the new QE-class carriers are the "latest"

they seem to be using electric final drive and the generation of the electricity is from either the gas turbines or the diesels
yes diesels for cruising ….. gas turbines for sprinting … generally but not strictly set that way it seems

having electric final drives makes perfect sense as you don't need to have your drive shafts aligned with your gas turbines etc …
and you can use pod drives … etc …. and gives you huge areas to design your ship differently re the engine room

its pretty obvious to me that you want final electric drive … its a no brainer
I can't see why it wouldn't all be DC …. so infinitely variable control should be a doddle
you only use AC to transmit power over long distances …

but yep definitely a big area of development …. everything will go this way
no doubt in my mind

as I've said endlessly on this site …. the 20386 corvette is a really important ship

I really like these discussions …. instead of the endless drivel about missiles etc

In terms of generating electrical power the GT is ideal... compact and powerful... they don't like dust but that is a problem on a tank but not a ship... and they don't take load very well so a T-80 or an M1A Abrams will burn a lot of fuel driving around the place... mainly because a lot of the driving for a tank is not on motorways at top speed... it is sitting behind a house in a village and then rapidly moving from there to another point of concealment... so stationary and then short bursts of maximum acceleration and then stop... which is very inefficient for a gas turbine, but fine for an electric drive vehicle with gas turbine energy production because the GT just maintains ideal revs to generate electricity... the problem is storing that electricity in a way that it is always ready and also ready in great volumes for fast acceleration from cover to cover.

On a ship you could just have several GTs where most of the time you only have one working generating electrical current to power everything on board and run at a modest speed... GTs are relatively quick and easy to start up so powering up another three GTs to power everything at full power and run at top speed is not a problem.

You will have a capacitor bank to temporarily store more power and batteries too and when needed you can fire them up too for extra speed and power.

Of course a small nuclear generator like a battery would be useful too for emergency backup, to get you home...

You could optimise the GT to run on LNG so it will be cheap to run as Russia has plenty of that to spare... and one LNG tanker with 200K tons of LNG could keep a surface fleet going for months or years depending on the tempo of operations.

Any news on serial production of the marine turbines?

Yes typically they have 2 diesels for electric generation and 1 or 2 turbines also for electric generaton or they turbines can also be dog geared to the drive shaft. They sit there while the ship pottered around in diesel electric mode maybe up to 12 knots or so. When the *hit hits the fan and they need to move they fire up the turbines and they they blast along at 30+ knots as soon as it is warm enough and spooled up...which in most cases is a few min. I would assume they also have oil heaters so the turbine will not be dead cold when it fires up.

Of course different vehicles are different... a lot of very large vessels have rather small diesel engines or small gas turbines to generate emergency power independent of the main propulsion systems and might be used for low speed get you home sort of situations when the main engine wont start but you need to keep things working and to move about.

Very much a sail back to home base at 6-8 knots and keep the lights on rather than stay in the battle and keep all the radars going and all the systems like communications etc etc.

Why?

Is the Russian Navy hitting them with Kalibrs yet?

YES. Please, go ahead.

I expect at least 1.000 words from you!

Very good news!   and a big Fuck You to the Ukro nazi scumbags!!  

The Kiev regime maggots are so smart that they are stupid. These retards thought Russia could not afford and was not capable of replacing
Ukr production with Russian-made products. They can now eat shit. Russia has managed to replace all Ukr engines with its own new and
more efficient designs. Ukr-tards can look on as their factories close and they permanently lose the ability to make the products that they
were previously exporting to Russia.

As for Russia taking out the Kiev regime. Why should it. The Kiev regime has solid support from 40% of Ukr-land. Russia has no obligation
to wipe the asses of these degenerates. They can spiral to null of their own samo-bozhe-vilnost and Russia can look on and laugh.

They have half a dozen sitting around waiting for diesels

What a imbecils.... why they produce ships if engines are not avaialbe? They havent any better way to sped money? And they do that again and again and again...

Isnt it obivious that they should stop production and spend money on project they could finish? Either military or civilian....

Lol they still rely on foreign parts for their engines? did they not learn their listen the first time.

What a joke.

Well they started working on it before 2013 most probably...

Doubt it, making their own engines was never a concern before then.

This is hilarious... please one person from one country tell me is your country self sufficient right now?

The US has Russian rockets in their possession and complete plans for their design but it takes them 10 years to build something that could do the same job.

China has had Russian jet engines in service for quite some time but really are having trouble copying them to get the same performance and fuel efficiency...

Do you think Russia and America and China are all idiots?

Is it really just a case of copying all the components and assembling them together and you have a working engine?

China has proved that not to be the case when Russia bought Chinese versions of German diesel engines and they were terrible.

When those boats were built they had contracts for the necessary engines that would go into them.

If you want to bitch and moan about incompetence moan about Germany blocking the sales of engines to Russia... the country bending over backwards to get them cheap gas so their production costs wont go up too much in the future... and why did they do that? Who remembers... putin invading crimea, putin invading the Ukraine, putin personally murdering people in the UK... or some such bullshit.

I personally feel sorry for the workers in France and Germany who just want to build ships and make engines while their politicians play silly games, but eventually it will get sorted with Russian engines to do the job and those Russian engines can then be sold on the international market in direct competition to the likely more expensive German engines and their Chinese copies. My father had a fishing boat that had a chinese diesel engine in it... it was fantastic. simple and solid and reliable... running it most of the day it was costing him about $12 in fuel... which means he was essentially burning about 24 litres of fuel a day... I know a guy with a fizz boat it costs him hundreds of dollars a day to run... he would use more than 5 litres of petrol to start the damn thing...

Doubt it, making their own engines was never a concern before then.

Foreign parts has always been a concern for the Russians. Made more so by western sanctions and general bullshit.

Making parts for an engine is not just a case of shaping bits of metal and putting them together.

In a jet engine there are lots of very complex parts made of alloys of several different metals combined... having the parts and therefore being able to analyse them and work out what materials are involved is not the solution... the super expensive high tech bits in French engines that America makes for them out of Titanium are made with Russian titanium. When Russia decided to make all its own engines in a range of families to suit any sized final product you want from tiny drone or cruise missile up to a transport to replace the An-225, the French made the offer that instead they could make the precision made titanium bits they get made in the US because they can't make them themselves... the offer they were hoping would get Russia to keep buying french engines and in return Russia would be making the money that the US is making providing the complex and very precisely made titanium parts in their engines... in the engines they use themselves and of course all the other engines world wide that the French make. An interesting offer, but with the case of the Mistrals... Russia can't trust France, so again American pressure on France costs France money and contracts and they stay tied to US components for their engines too.

A diesel engine is not as complex but a big powerful diesel engine will need very precisely made parts and specific alloys will need to be used for it to work properly.... make a part to the wrong hardness and it might be too soft and wear out quickly leading to breakdowns and needing replacements. Too hard and the piece might shatter or crack and do damage to other parts and again lead to breakdowns and needing replacements.

A ships engine is not like a car engine... you can't just pop the hood and fix the problem or if necessary take the engine out and fix what needs to be fixed and replace what needs to be replaced.

Over time the Chinese are going to work out what parts are the issue and get the hardness right... it was probably the reason they used that special alloy of several metals to make it... but that wont show on the plans...

Their problem is a lack of domestic diesel engines in a specific power range... there is clearly a need so it really shouldn't take too long with their modular and scalable powerplants drive to get to a solution for this and other boats with the same problem.

Few countries with good products will provide full ToT to just anyone without getting paid the equivalent of selling the product to anyone who might buy it, because once you sell it and if you stop selling it... lets face it... not just likely for Germany and France to Russia... it happened, then once you sell ToT you have to expect them to not only keep making them but also to include them in products they sell to others which will cut into your sales of your own product.

Russia isn't having a shit fit over China making Flankers because they are using them domestically and don't seem to be making them in huge numbers... if it is just for domestic consumption then they don't over react.

but eventually it will get sorted with Russian engines to do the job

and when is this going to get sorted out? its been 6 years since Ukraine blocked sale of ship engines to Russia, how much more time does Russia need to develop a working domestic engine? 20 years? 30? by that time the engine they are making will be obsolete
