The first domestic engine for gas transportation, the NK-36ST-32, was presented.

Russia has developed the first domestically produced 32 MW gas transportation engine, developed by the United Engine Corporation.

The first domestically produced 32 MW NK-36ST-32 engine was developed based on the serial 25 MW NK-36ST-25 engines and completed the first stage of factory testing in September of this year. According to the corporation, Russia has never previously had domestically produced engines of this power for gas transportation, and these are the most sought-after units in the gas industry.

A prototype of the new NK-36ST-32 engine successfully completed the first stage of comprehensive factory testing in September 2025. During these tests, the engine reached its nominal power of 32 MW and confirmed its stated technical specifications.

– stated the General Director of UEC, Alexander Grachev.

According to the corporation, the NK-36ST-32 boasts the highest efficiency among Russian gas turbine engines for gas transportation, reduced fuel consumption per unit of power, a long service life, and meets all environmental standards. After passing all necessary tests, it will be included in gas pumping units.

Currently, designers are creating an engine version for operation in southern regions at high temperatures, as well as in high-altitude conditions.

The NK-36ST-32 has the highest efficiency among Russian gas turbine engines for gas transportation,

Nord Stream 3, Power of Siberia 4....

[rocket757]

We have a large country, and transporting gas over long distances is a completely internal matter... incl.

[rocket757]

It's obvious... you can't rely on anyone, only yourself, all by yourself...
Although, various small things from the list of what is needed, but not critical, can be bought where they do it normally and at an affordable price.

[Antiglobalist]

But were these engines previously supplied by Siemens? Thanks to Western sanctions, you'll soon become self-sufficient. According to AI, their capacity was 40 MW.

[tralflot1832]

The gas turbine (engine) market in Russia in 2014 was estimated at 1000 units. Siemens was sad.

[barclay]

Everything is business as usual. We're catching up with the decaying West. It's surprising that since the Soviet era, we haven't been able to create our own engine to transport our own gas. And this is considering the country's size.

Based on the NK-32-02 gas generator. I wonder if the NK-36ST-32 has anything in common with the Izdeliye RF (Product RF), which was also based on the Izdeliye R (NK-32-02) gas generator?

The NK-25, or product "E" in production, is a turbofan engine with a bypass, three-stage afterburner (TRDDF), produced at the Kuibyshev Engine Plant from 1977 to 1996. The NK-32 (working name product "R") was an improved modification of the first.

The renowned Russian engine manufacturer UEC-Kuznetsov (Samara) is completing the design of a new version of the NK-36ST industrial gas turbine engine, designated the NK-36ST-32. The engine is based on the gas generator of the NK-32 aircraft engine, used on the Tu-160 strategic bomber. The NK-32 is currently in serial production. Gazprom is the customer for the NK-36ST-32. Previous versions of the engine are used in gas pumping units at the company's compressor stations. During production and operation, the engine undergoes refinement, improving its performance. In 2016, the NK-36ST received a low-emission combustion chamber, which reduced harmful emissions, and serial production began.

At least the power, and therefore the thrust, have been increased.

Development of the Russian NK-36ST-32 industrial engine has been completed, with a prototype unveiled in early October 2025. The engine is based on the gas generator of the NK-32 aircraft engine, used on the Tu-160 strategic bomber. The NK-32 is now in serial production.


The NK-36ST-32 is a further development of the 25 MW NK-36ST (NK-36ST-25) engine, which is commercially available for gas pumping units at compressor stations. The new power unit's output has been increased to 32 MW.

Well, let's say the United States cannot enrich uranium, does not build icebreakers, does not produce lithographic machines and televisions.
China also has gaps in production.

More like Japan, and comparable in population to Russia.

[Nastia makarova]

Japan is not even close....

[Nastia makarova]

The US doesn't make a lot of things on its own, so if they're slapped with sanctions like we are, it's kaput. And even though China is the world's biggest factory, it doesn't make everything either.

The US is doing something? Wow! And the men don't know! So what is China selling them in such quantities?
China can't do everything either.

It is surprising that since the times of the USSR they have not been able to create their own engine for transporting their own gas.

In the USSR, NK-12 engines, retired from aircraft (Tu-95 and An-22), were initially used for this purpose and converted to run on gas instead of kerosene. Later, NK-16 engines were produced, specifically adapted for gas use and intended for gas pumping stations.

But these engines were previously supplied by Siemens

Gas turbine engines with a power greater than 25 MW, which have long been produced in Russia, are only produced by GE and Rolls-Royce in the aviation version. Siemens bought decommissioned aircraft engines, equipped them for use in the ground version, and sold them.
I don't even know if there are ground-based options for gas pipelines with a capacity of over 32 MW; Siemens made them to order from decommissioned GE and Rolls-Royce aircraft engines.

[Ross xnumx]

Will this somehow contribute to filling empty pipes in the Leningrad region, or will it remain just another achievement for the country?
Here Manturov announced about labor productivity:

According to Russian First Deputy Prime Minister Denis Manturov, announced at a joint meeting of State Duma committees in preparation for the government hour, a 25% increase in industrial productivity is expected by 2030. Manturov noted that the civilian industrial sectors have been experiencing stable, multi-year growth dynamics of 3–4% annually.

With such highly efficient engines, will gas prices...start to rise at a rapid rate?

[malyvalv]

What happened to the gas in the Leningrad region?

[Ross xnumx]

A completed gas pipeline – no gas: People in the Leningrad region are on the brink of extinction.

Look for yourself...

As of the end of 2024, the level of gasification in Russia was 74,7%.
According to the state program "Energy Development," this figure will reach 75% in 2025, 75,8% in 2026, and 76,7% in 2027.

ROSS 42 will build dachas in the Karelian wilderness, far from populated areas, and then demand preferential gas connections. And what does profitability mean?

Andrew!
I happened to live in the village of Seleznevo in the Vyborg "backwoods." We were periodically supplied with gas through a gas tank. I don't think it was cost-effective, but the buildings were multi-apartment. And the gas tank looked something like this:

[tralflot1832]

In Murmansk, only five-story buildings were supplied with electricity from such gas holders. And it seems that all five-story buildings were supplied with electricity.

[malyvalv]

Is this a cottage community that decided to build a pipeline at its own expense but is still struggling to get connected and is on the brink of survival?
But the Leningrad region, in your opinion, is without gas. The whole thing.

The key idea here is - will remain another achievement of the country?

[malyvalv]

In the logic of your question, "Will a super-powerful engine help fill the pipes in the Leningrad region?" it's very difficult to discern that the idea is about the country's achievements.

[balabol]

Yuri, you have linked two different questions together.
A gas pumping unit will certainly help fill the pipes with gas; is that really in doubt?
Residents of the Leningrad Region are connecting to the gas grid. To see this, you need to read the gasification plans. Much has been accomplished in 23-25, more than in the previous 10 years.
Not all of the Leningrad region has run out of gas, by any means.
Residents of the cottage community linked to by you began laying their own gas pipeline in violation of the rules. The gas company refused to accept it for operation.

[Andriuha077]

Well, here it is, something on time.
In 2024, UEC-Kuznetsov plans to produce the first prototype of the NK-36ST-32 engine with increased power for use at compressor stations.
The NK-36ST-32 is promised to be able to operate at 25 MW at temperatures up to 40 degrees Celsius, with an efficiency of 38%. It is being tested at the Tolyattinskaya compressor station. scheduled for 2025.

But since then, things have become much more interesting: the plant has implemented a comprehensive technology additive Production began to literally "grow" engine parts using lasers. Using direct and selective laser deposition methods, the production process was accelerated by 15% and the material utilization rate increased to over 70%, while the defect rate remained below 5%.
The NK-36ST is a 25 MW engine used at gas pumping stations across the country. The engine was developed based on a conversion of an aircraft engine. gas generator NK-32 and has been produced since 1996, But it's constantly being improved and modernized. In 2024, we're promised the next, updated version of the unit with an efficiency of 38%.

But since then, things have become much more interesting.

[Andriuha077]

The NK-36ST is an engine based on the conversion of the NK-32 aircraft gas generator. It has been produced since 1996, but is constantly being improved and modernized.

The "R" product, or NK-32 bypass three-shaft turbojet engine, was developed in the Soviet Union at the Kuibyshev Engine Plant. Nikolai Dmitrievich Kuznetsov was responsible for creating this unique powerplant. The NK-32 was developed in 1977 and entered service in 1983. After the collapse of the Soviet Union, the Americans sought to acquire the NK-32, and in the 2000s, Chinese specialists also expressed interest in the engine. China is actively developing the H-20 strategic bomber.

The H-20 is believed to have been in development since the early 2000s. According to China Daily, the Chinese military wanted a long-range bomber (up to 8 km) that would not require in-flight refueling and could carry up to 10 tons of weapons.
During the development of the aircraft, measures were taken to reduce radar visibility (stealth technology).
China will thus skip the stage of developing and owning analogues of the B-1B and Tu-160.

Some experts speculate that the H-20 may use the Russian NK-321 engine (a variant of the NK-32, a two-fan, three-shaft turbofan with afterburner); two independent military sources also stated that the bombers will be equipped with an upgraded version of the WS-10 engine (used on the Chengdu J-10).

[Sky strike fighter]

Am I correct in understanding that the NK-36ST-32 engine, with its new power unit increased to 32 MW, is based on the Izdeliye RF engine? While the production 25 MW NK-36ST-25 power unit was based on the production Izdeliye R, also known as the NK-32-02. The NK-36ST-32's power was increased to 32 MW, or almost a third of the NK-36ST-25's original 25 MW.

The NK-36ST-25 with a capacity of 25 MW was created on the basis of Product R.
Performance characteristics of the R(NK-32) product
Thrust: 14000 kgf
Afterburner thrust: 25000 kgf
Compressor. Weight 365 kg, three-stage fan, 5 medium-pressure stages, 7 high-pressure stages
Turbine stage one high pressure, one medium pressure and two low pressure
Turbine temperature 1302[3] °C
Multi-nozzle annular combustion chamber
Pressure increase ratio 26,8
Electronic control with hydromechanical backup
Specific fuel consumption: 0,72[4] kg/(kgf h)
Bypass ratio: 1,4
Specific thrust: 6,85 [5] kgf/kg

This means that the takeoff thrust of the Product R is 25 tons (the D-18T has a takeoff thrust of 23,4 tons, for comparison). The NK-36ST-25, with a power output of 25 MW, was created on its basis.

Then the takeoff thrust of the Product RF turns out to be equal to 32 tons of thrust, if the thrust is increased by a third of the original thrust of the Product R. That is, it produces thrust almost like the PD-35. And it turns out that the NK-36ST-32 was created on its basis, where the power was increased to 32 MW, that is, by a third of the power of the NK-36ST-25 with a power equal to 25 MW and created on the basis of Product R (takeoff thrust with afterburner 25 tons).
What am I getting at? Is the RF product really ready, which is what allowed the NK-36ST-32, with a capacity of up to 32 MW, to be developed on its basis?

Interestingly, the NK-32-02's potential isn't limited to the Tu-160 family of projects. It has been repeatedly reported that this engine will be used to develop a new engine for use on the advanced PAK DA bomber. It has also been proposed to develop an NK-32-based engine for the An-124 transport aircraft.

Only if we assume a direct relationship, regarding long-term thrust

[Sky strike fighter]

Well, the engine thrust is declared based on the thrust in takeoff (boosted) mode.

TTX D-18T.

Takeoff mode (H = 0, Mn = 0, ISA):

Traction, kgf (kN) 23430 (229,85)
Specific fuel consumption, kg / kgf h (kg / h h) 0,34 (0,0347)

Cruise mode (H = 11000 m, Mn = 0,75, ISA):

Traction, kgf (kN) 4860 (47,68)
Specific fuel consumption, kg / kgf h (kg / h h) 0,546 (0,0557)
Fuel consumption with a thrust of 5400-4800 kgf Ce (Н 36100 М-0.75 МСА + 10) 0.568-0.625 g / kg * h

It turns out that Product R (NK-32)
The takeoff thrust is 25000 kgf.
And the D-18T
The takeoff thrust is 23430 kgf.

And the Product of the Russian Federation
The takeoff thrust is 32,000 kgf.

If we take into account that NK-36ST-32 was created on the basis of Product RF, and NK-36ST-25 was created on the basis of Product R.

What details do you need? About this top-secret Russian product? You'll find out when it's launched at its intended use. Nothing was known about the Su-75 either, and then suddenly a photo leaked from a runway showing two Su-75s parked on it! I wouldn't be surprised if they were already flying full-scale. They'd leak a Russian product much faster; their airfield is right in the heart of a major city.

It will be a circus when it fails INTERGAZSERT certification and is not accepted by Gazprom.

Samara's Kuznetsov plant makes engines for gas pumping. Where did the development come from?

[Fangaro]

Gas has always been there. Money has always been there. Partners have always been there.
And suddenly it turned out that it was the gas that was ours.
And the money for gas turned out to be someone else's?
It's like planting potatoes with your own hands, watering, hilling, fertilizing, digging, drying, sorting, taking them to market, selling, enjoying the income, planning for the New Year... And suddenly finding out that the field is not yours, but you can keep as much as they allow.
