A prototype engine for PAK DA is being prepared for bench tests

A prototype of a new engine for a promising long-range aviation complex aviation (PAK DA) has already been created, it is being prepared for bench tests. This was announced by Alexei Sobolev, deputy general director - managing director of UEC-Kuznetsov.

According to Sobolev, a prototype of the new engine is currently at the assembly stage, and by the end of the year it will begin bench tests. The engine documentation was completed in 2020.

This year the engine is made in iron and is being assembled. It will be assembled before the end of the year to start bench tests. Key competencies of the majority of enterprises of the United Engine Corporation are involved in its completion.

- he explained.

At the same time, Sobolev did not give details about the new engine for a promising long-range bomber.

The start of the development of an engine for PAK DA in the United Engine Corporation (UEC, part of Rostec) was announced on October 1, 2018. The contract for the creation of an engine for a promising bomber was concluded between the UEC and the Tupolev company in June 2018.

According to reports, the new engine should provide a flight duration of 30 hours, operate stably at air temperatures from minus 60 to plus 50 ° C and be resistant to the effects of the damaging factors of a nuclear explosion. The service life of the PAK DA engine is determined to be 12 years (subsequently it can be increased to 21 years). Engine thrust is expected to be 23 tf.

So what will be the successor of the glorious traditions of long-range aviation of our Motherland? Supersonic, like the TU-160, or a subsonic stealth platform ...

Supersonic, like the TU-160, or a subsonic stealth platform ...

There is no sense in supersonic, there is no need to approach or enter the air defense zone.

[Doccor18]

And the speed of the platform itself?
Indeed, even a difference of 300 km / h gives a significant gain in time.

[lucul]

And the speed of the platform itself?

American radars do not see stealth aircraft, so there is no special expediency in supersonic))))

And the speed of the platform itself?
After all, even a difference of 300 km / h gives a significant gain in time

I think the stake is on the long-range cruise missiles themselves, the launch vehicle should not enter the air defense zone at all. Subsonic speed, with all its disadvantages, allows for a much longer flight (patrol) duration

[Bad_gr]

Quote: Gregory_45

the stake has been placed on the long-range cruise missiles themselves; the launch vehicle should not enter the air defense zone at all. Subsonic speed, with all its disadvantages, allows for a much longer flight (patrol) duration

Some cruise missiles have a ramjet engine that requires a certain speed to launch. If the aircraft has insufficient speed to launch a ramjet engine of a cruise missile, then this missile will have to be accelerated with a powder engine, which is additional weight. That is, for example, instead of six rockets, the plane will take only 4 rockets with powder boosters.
I mean, 300 km / h can be a significant factor for some missiles.
Where am I mistaken?

in my opinion, you are not looking for flaws there. The ramjet is launched at speeds of 0,5M and higher. Therefore, if the rocket is not hypersonic, it does not need supersonic to start the engine.
And it is extremely unwise to sacrifice the flight characteristics of the aircraft, adjusting to the rocket. The launch booster is a small and not heavy thing, the number of missiles taken on board from a missile carrier is usually determined not by the carrying capacity, but by the possibility of placing missiles in a given volume.

[Cananecat]

And to sacrifice the flight characteristics of the aircraft, adjusting to the rocket is extremely unreasonable.

Ok ... are you considering future missile improvements? What start characteristics can they require?
In my opinion, supersonic is needed for an airplane, it's just one of the modes.

[Grigory_45]

Quote: Canecat

In my opinion, supersonic is needed for an airplane, this is one of the modes, just

for which you will have to pay a considerable price. To step over the sound barrier, the thrust will have to be doubled, in two Machs - almost eight times. With the appropriate aerodynamic layout. A flying wing to fly supersonic, I suspect, is another problem.
Of course, the military would like to have great speed in one object, and the ability to fly low, in the stratosphere, and even in space, fly far and long, and carry as many gifts as possible for "friends". Only constantly have to compromise, prioritizing what is more important in each particular aircraft. well, starting from what the development of technology and technology can offer. By and large, everything always rests on the engine.

Supersonic will definitely help to quickly get to the launch area.

Quote: Herman 4223

Supersonic will definitely help to quickly get to the launch area.

Only if the line (launch area) is completely ... "side by side"

[Herman 4223]

It can fly two thousand kilometers at supersonic speed, maybe even refueling in flight.

Quote: Herman 4223

Two thousand kilometers at supersonic speed, it can fly

So you speak for "sho say" ... for the Tu-160? ... And we seem to be for the PAK-da (with a maximum take-off G of 100 tons)

Quote: Herman 4223

Two thousand kilometers at supersonic speed, it can fly

Maybe Tu-160 ... in cruise mode M = 1,5 ... and the launch line is at a distance of 5-7 km ... then what to do ...?

[Herman 4223]

Have you already defined the line and goals for him? Cruise missiles fly far if anything, and he is their carrier. And not the whole flight at supersonic speed can be, but only some segment. And it will reach the launch line faster than the Tu-95 or the new Pakda. This time can make a difference.

Well, yes .... if only "all the time to sit on the priest exactly and wait for the weather by the sea"
And not to spread out in a threatened period in dangerous directions, to increase the lines of reach.

[Herman 4223]

If for the previously spread out it's great. But the threatened period is a loose concept, airplanes cannot constantly hang in the air. And at the moment of an enemy attack or when it is recognized that it will begin in the near future, the aircraft may be on the ground. After all, they still need to be prepared for departure. It's good if the moment of the enemy's attack becomes known earlier. And if in an hour?

[ancient]

Quote: Herman 4223

This is the first and foremost action in aviation as intended.

Such an element is also present in the database management techniques ... it is applied from the existing tactical and operational training.

Quote: Herman 4223

And at the moment of an enemy attack or when it is recognized that it will begin in the near future, the aircraft may be on the ground.

For this, such an action plan is provided as - getting out of the blow.

Quote: Herman 4223

The planes are ALWAYS in operational readiness for an immediate departure (time ... very, very small for "all things" )

Quote: Herman 4223

It's good if it becomes known about the moment of the enemy's attack earlier

For this, there are "special" kind of VS, which "chew their carrot"

Quote: Herman 4223

And if in an hour?

With a head .... with an interval of 30 seconds (on a runway 100 meters wide, it is possible with 15 seconds), the Tu-22M3 regiment "leaves" in ... 5 minutes the whole ... even the staff and those. the train will have time for transport

[Nikon O'Conor]

Troops included in the strategic nuclear forces (or triad) are in constant combat readiness, if I am not mistaken in the "constant" apart from them, only the Airborne Forces. So pre-flight preparation is carried out constantly and the departure time is minimal.

Supersonic makes no sense anymore

The military believes that there is such a meaning. Therefore, the production of the Tu-160 has been revived on a modern element base with a more significant use of composites in the airframe design.
PAK YES is not considered as a replacement for TU-160 + TU-95, but only as a replacement for the subsonic TU-95.

The Tu-160 is being modernized in order not to be left without bombers until the PAKDA is adopted.

Interfax

On February 14, 2019, the developers and customers approved the final sketch of the PAK DA. The necessary characteristics of the aircraft have been agreed, which will replace the Tu-160, Tu-22M3 and Tu-95 missile-carrying bombers currently in service with the Russian Aerospace Forces. According to sources in the Russian defense industry, “all contract documents necessary for the production of samples have been signed” [14]. In August 2019, technical requirements were approved and the preparatory stages of design began

[VO3A]

Tu-160s were modernized so that they flew with a serviceable modernized complex ... Before that, on most aircraft, the complex was not only old, but still not serviceable. This complex is also molded on the "dying" Tu-22M3, for this modernization of the aircraft was invented, which will be written off in 10 years ... And the release of new ones was needed to restore production and lost technologies to prepare for the production of PAK DA .... And that's enough on the screensavers depict the fantastic appearance of the aircraft, the real view of the PAK YES is on the Internet !!!

And the release of new ones was needed to restore production and lost technologies to prepare for the production of PAK DA ..

The first serial PAKDA will only begin to be made in 10 years, so the Tu-160 needs to remain in service for another 20 years, so far there is nothing without it.

[VO3A]

without it yet.

That's a moot point. This "stadium" is visible on all radars and the airfields where it can be based is easy to count. It is very easy to track and visible to everyone else on the ground. A very costly and uneconomical plane, but rather a symbol of the power of the state, no more ... Yes, and missiles from the ground fly in the same way as from it over the home airfield, there is no difference ... And the maximum that he has time is to take off, and in the best case ... he is not on duty, and the preparation time with missiles is huge ..

[Nikon O'Conor]

As a pilot, do you assert? It's just that from my experience I know RS 20 (Satan-NATO), after 30 years (the service life has expired), every year there was an extension of the term (they called the specialists of the independent YuzhMash) for a year, and was not on duty until the replacement (at least p. Clear). Why is it wrong with triad planes?

[fa2998]

Sergei, what an optimist you are with us! In ten years, you can only roll out the FIRST experimental, experienced. Until the serial (if any) not earlier than 2040.

This option was in the article above

Or like this, to be more reliable.

But no - these are FANTASTIC options
And this one is true for you:

And you consider it reliable data from a popular scientific Internet publication, okay. but let's read at least a few lines.

The PAK DA power plant will be composed of bypass turbojet engines with a thrust of 23 tf - probably, there will be four of them, and they will be unforgeable.

Explain to me how it is PROBABLY there will be four engines, but in the picture of your resource?
And more sir !!! The author of the article reviews the topic and we (chatlan - if you want) discuss the topic of the article and not the picture. Because the discussion of Pictures will be when the author of the article asserts the reliability of the picture itself.
P \ S But the minus is not mine.

[VO3A]

Look at B-2 as well. And impressed or not impressed - this is the second moment ... At least, at least, closer to reality than all the other fantasy pictures put together ...

It is better to make a PAK YES based on the Su-34, 30 engines and PAK FA technologies .. .Because everything is there! Take the lineup of the Su-34, but in the STEALTH version, increase it slightly in size so that everything fits into the internal compartment between the engines, and also make it, this compartment, removable! So that the plane can be used with external suspensions ... Now the project is ready and in 3 years we are already implementing it in a particular plane ... The whole base is there ...

This is also my .. "not a sales dream." Back in 1996 ... I went around the "bike" that the General Staff of the Air Force "matured the idea" to re-equip two YES regiments from Tu-22M3 to Su-34 .. .but so it remained a dream.

[VO3A]

This is not a dream, this is a belated necessity, but it will soon be realized out of hopelessness ... The Su-34 can carry between the engine nacelles any new missile if desired ... Everything will fall apart, but the Su-34 will remain and replace everyone ... And it is necessary to make 30 of them every year and reach this pace as soon as possible ... When these cretins understand this ... Install new engines that are, and work with invisibility using PAK FA technologies ... And not release unnecessary ones Tu-160M, modernize any rubbish, and not plan to release new monsters in the form of PAK YES, which may appear in 20 years ... Here is the state approach, cheap and cheerful ... And with refuelers, in general, all questions are removed. ..Chew gentlemen-sawers ...

And what else should he hang between the gondolas, so that the flight range would quadruple (as a strategist) with at least twice the bomb load (for comparison, the Tu-160 has up to 40 tons)?

[VO3A]

Can't you answer this question yourself? Why range strategist if he has long-range missiles? He launches missiles without entering the detection zone! And where will this "stadium" not be found? In theory, only if you fly to the North! But they see him already on earth! Spy satellites hang over Russia, and new ones with mirror telescopes generally see everything ?! In theory, he should launch his rockets on the ground while standing in the hangar !!! And then why is it needed? With refuelers, simply the question of the radius disappears ...
And most importantly, if you shoot down an aircraft that can destroy 20 targets with its 20 missiles, it will not destroy a single one ... And 20 aircraft with one missile from different small airfields will not shoot down all, and they will destroy some of the targets with missiles with nuclear weapons, but here and just one hit is enough to sober up the enemy! Do you think?

Why range strategist if he has long-range missiles?

Will he throw free-fall cast iron bombs while standing in the hangar?
In Afghanistan, there was such a need during the operation on Panshera, when strategists from the alliance entered to bomb the object.
And it should not be forgotten that unlike submarines and strategic ballistic missiles, aircraft (like ships) have the ability to "demonstrate strength." That is, when an airplane with nuclear missiles on board is patrolling near your borders, it puts a lot of pressure on your nerves and contributes to a faster search for compromises.

The meaning of what I have written, among other things, is to drop ordinary bombs. And that would be enough bombs to complete the task.

this depends mainly on the design of the ammunition compartment. Does it have cast iron locks and sufficient volume

Quote: Bad_gr

And since there are many bombs to lift and deliver far, you need to have a lot of fuel with you

or relatively economical engines and subsonic altitude flight profile. PAK YES - "hundred tonnage", do you think it will take a little fuel? Well, nobody canceled refueling.

The Tu-160 is being modernized in order not to be left without bombers until the PAKDA is adopted.

the modernization of the Tu-160 in service actually ended with the Tu-160M ​​aircraft.
The TU-160M2 is actually a new aircraft in which only the shape of the airframe remains from the TU-160M ​​and all the filling from the avionics to the engine is completely new.
The Ministry of Defense plans to increase the total number of TU-160s to 2 with the help of the TU-160M50, but now Russia has only 16 such aircraft of various modifications. In fact, Russia will have to build dozens of new "white swans" whose service life is at least 30 years.
It finally dawned on the military that the PAK DA was not able to fully replace the TU-160, which are much ahead of their time in modern times. in service and no one would release new TU-160.
By the way, they decided not to give up the Tu-22, but to resume the production of new Tu-22M3M aircraft, which will have only a glider from the old Tu-22M3 and the flight range, thanks to the installation of more economical NK-32-02, will grow to 10 thousand kilometers.
So, at the moment, only the Tu-95 will go down in history, although UEC "Klimov" proposes upgrades for it that will increase the resource of its engines by 4 times. But it looks like the military decided to further modernize it.
Nobody intends to abandon hypersound in strategic aviation in favor of subsonic ones.

[Ratmir_Ryazan]

There is a sense in supersonic - it is the speed of reaching the missile launch line.

Therefore, in Russia, the Tu-160 is left in service and modernized, and the PAK DA will replace the Tu-22M and Tu-95.

PAK DA will have a subsonic cruising speed throughout the entire visibility and will be made using low-signature technology.

[Fan-fan]

There is a sense in supersonic - it is the speed of reaching the missile launch line.

The speed of reaching the missile launch line in this case does not matter, since the missiles themselves are subsonic.

[Guru]

The speed of reaching the missile launch line in this case does not matter, since the missiles themselves are subsonic

Wow This means the time / speed of entering the enemy's air defense zone, reaching the missile launch line, launching missiles, leaving the air defense zone. Doesn't matter to you?

[Ratmir_Ryazan]

The speed of reaching the missile launch line in this case does not matter, since the missiles themselves are subsonic.

In your opinion, there is no place to rush in a war?)) After 1 hour to bomb or after 3 hours without a difference, all the same, missiles still fly for 3-4 hours))).


Speed ​​is important, very important. Only we will not be able to make all the aircraft like the Tu-160, therefore, for simpler tasks, the aircraft is made simpler and cheaper, both in cost and in operating cost.

I disagree! Some weapons require a high carrier speed. The dagger on the 31st was so hung up in vain. Or scramjet. True, we still need height, but how can we unhook it in the dense layers of the atmosphere? Again, speed and altitude increase range. And yes, subsonic is more economical.

There was information that it was based on NK-32, but let's see what happens in fact.

I think the option is yes to the PD-14 base

most likely on the basis of NK-32 all the same ... At least somehow infa slipped through that they were going to do just that, but with a new gas generator.

What are its main non-secret advantages in comparison with the old ones?

The temperature in the combustion chamber is about 200 degrees higher than that of the previous generation engines, while maintaining the same resource.

I think it will be a long story

The main thing is that the engine is already in the gland, the main thing is to bring it to mind and test it now.

SAMARA, 23 Dec - RIA News. The first prototype of the engine for the promising Russian PAK DA bomber, named "Product RF", is being assembled at the UEC-Kuznetsov enterprise (part of the United Engine Corporation "Rostec"). The Deputy General Director - Managing Director of the plant Alexei Sobolev told the journalists about it.
"The first engine" in hardware "has already been manufactured, is now being assembled and will be ready for bench tests by the end of the year. We plan to start them early next year," he said.

According to Sobolev, this power plant is the result of extensive cooperation of almost all enterprises belonging to the UEC.
"This broad cooperation allowed us to complete the development of drawings in a fairly short time, the documentation was actually completed this year, and in parallel, the product was designed in full digital, which allowed us to quickly launch the production of the first prototype," he said, adding that in the next several more such engines will be manufactured for testing.

[midivan]

Yes so Documentation and in the same year dvigun, for me personally, this year 2020 acquires more colorful colors than it is commonly believed with pandemics and any other evil spirits

[Orange bigg]

So the serial NK-32-02 (aka Product P) was taken as a basis. The Product of the Russian Federation was not developed from scratch.

[Genry]

Apparently it will be a subsonic version, which is also suitable for remotorization of the An-124 Ruslan.

[Orange bigg]

Absolutely.

[Ros 56]

This is good news, and if it finds widespread use, it will generally be beautiful.

[Orange bigg]

It would be nice to replace the Ukrainian D-18Ts on the An-124 with our engine for the PAK DA. And there, and there thrust at takeoff mode is 23 tons.

[Tooks]

Alas, there is nothing to change. Apparently not expected.

[Orange bigg]

How is that nothing? And the RF product has the same thrust of 23 tons as the D-18T?

[Tooks]

The fact is that the RF has a very low degree of bypass (like the progenitor). It is understandable - an engine with a high bypass ratio in Tu-160 and PAK-DA simply cannot be crammed because of its size. So this is not suitable for the An-124, first of all because of the high fuel consumption.
Most likely An-124 will live out their days with what they have. There is only one way out - a new heavy-duty truck with its own engine.

[Orange bigg]

So this is not suitable for the An-124, first of all because of the high fuel consumption.
Most likely, the An-124 will live out their days with what they have.

This is your guess. No more. An-124 is needed first of all by the military, and for them the main thing is that the planes fly, they will think about fuel consumption last. An-124 is not a commercial project like the same MS-21. It is a matter of the country's defense. In terms of size, the RF product will completely replace the D-18T.

[Tooks]

If you think so, then of course. How many An-124 does the military have? I personally don't know, but I don't think that much. Carry out a remotorization of one and a half dozen aircraft? It's expensive anyway. And in terms of time - the development of documentation and the actual work. At our pace, this will take at least 10 years.
There is also something like the An-124 at Volga-Dnepr.
In any case, the task is difficult and it is not a fact that they will be engaged in it. Is it better to intensify work on a new truck? I look periodically there are materials on "Elephant". In principle, the plane seems to be of the same class as the An-124. Maybe the engine will be made on the basis of PD-14. The PD-8 demonstrator seems to be threatened to be launched next year. There's also PD-35. I don’t know how the priorities will be set.

[Orange bigg]

At our pace, this will take at least 10 years.

How many years will it take to develop the Elephant from scratch, plus the time to create and fine-tune the PD-35, 4 of which will be equal in thrust to 6 D-18Ts (23 tons each)? and now. So the remotorization of the An-124 to engines. Product of the Russian Federation is the best option.

I look periodically there are materials on "Elephant". In principle, the plane seems to be of the same class as the An-124.

With 4 PD-35, he will have traction like Mriya with her 6 D-18T, whose classmate he, in fact, will be.

[Tooks]

In general, I do not understand for which aircraft our PD-35 is made. For the IL-96? The aircraft needs to be practically redesigned for this engine. Truck? Why does he need such an engine?
In principle, if it presses, then you can put the Russian Federation on the An-124. Or is it better to make PD-24 based on PD-14? Perhaps this would be the best option.
It is a pity that NK-93 was buried in due time. If he increased the thrust, then he would fit perfectly on the An-124.

[Orange bigg]

In general, I do not understand for which aircraft our PD-35 is made. For the IL-96?

For the joint Russian-Chinese passenger wide-body, for the Russian commercial passenger wide-body Il-96-400, for the Elephant.

Or is it better to make PD-24 based on PD-14?

On the basis of PD-14, only PD-14A (12 tons) and PD-14M (16 tons) can be made. All other engines, be they PD-8, PD-24, PD-35, are separate developments both in terms of materials and in terms of engine designs. The idea of ​​the PD-24 is not bad and I hope it will be, but alas, not soon.

It is a pity that NK-93 was buried in due time.

Now, why remember it? New time. New engines are needed for modern requirements. We must look forward, not backward.

[Tooks]

I'm afraid the Chinese will not wait for our engine and will install an American or English one. Although they may have to wait if relations with the Americans continue to deteriorate further.
For the IL-96 it is very doubtful. Who will do this work? "Il" is occupied by Il-114, Il-112. It is not very clear what is there with the Il-106 and the replacement of the An-12. And will we be able to produce an analogue of the B-777 in sufficient quantities for expediency.
For a new truck, PD-35 does not fit at all - two is not enough, four is a lot.
It is clear that the PD family based on PD-14 is actually independent engines, but we are not talking about development from scratch, but based on the existing gas generator. With proper organization of work, this can significantly gain time.
Well, let's see what comes out of all this.

[Orange bigg]

For the IL-96 it is very doubtful. Who will do this work? "Il" is occupied by Il-114, Il-112.

Why is it doubtful? Why do you think the new Il-96-400 was actually built, albeit with 4 PS-90A1? To work out the technological basis for the modification of the Il-96-400 with two PD-35 PD-2. Why is Il-35-114 so busy? -300.

but based on the existing gas generator.

How are you going to make a gas generator for PD-14 on the basis of the PD-35 gas generator? Completely different temperature levels. Different materials. In PD-35, in general, everything is for the first time and again. This was not even in the USSR.

[Tooks]

You probably have a very bad idea of ​​the complexity of the task of converting a four-engine aircraft into a twin-engine one. And further. How many 777/767 and A-330 aircrafts do we have? I don’t think there’s even a hundred. So is it worth building a garden for a hundred (theoretically) planes?

And about the gas generator. Well, not as literal. There is a design and technological groundwork, using which it is really possible to design a whole family of engines.

[Orange bigg]

So is it worth building a garden for a hundred (theoretically) planes?

And what will you fly when the sanctions are introduced and the supply of spare parts for Western aircraft is denied? to produce no planes at all, and only buy everything in the West, but countries become rich when they produce something, albeit at first not very qualitatively, but over time the quality grows, and business develops (example of China), and those who argue how you turn in the underdeveloped poor dependent countries. In the 90s, we already passed this slogan we will buy everything for money from oil in the West, then led the economy to disaster, since production was destroyed. So I will answer your question. What a business , development. And if you sit and pick your nose, you will never build a strong economy.

[Tooks]

I'm talking about the economy, and you are talking about politics.
This, of course, must be done, and to begin with, oust foreigners from domestic lines. But this requires will. Let's hope that's enough.

[Orange bigg]

I'm talking about the economy, and you are talking about politics.

I mean that there will be no economy, in principle, if you do not produce goods and, as a result, do not trade them at least in the domestic or foreign markets. Countries that are friendly with their heads always support their producers, introducing the same protective duties. deductions to your budget, the budget of the country. Do you believe in the hand of the market, which for verification turned out to be cleverly disguised by the machine hand of Western manufacturers to hack the markets in favor of their goods?

[Tooks]

So you and I seem to be only "for". The only thing left is to produce a sufficient number of airplanes and to be taken by our a / c.

[Orange bigg]

That's right. We have to work up our sleeves, and do not ask if we should or should not produce airplanes.

Forbes doesn't want to believe you.

A well-known publication announced that the Dagger missile did not exist.

Despite all the prospects of the Russian hypersonic aviation missile system "Dagger", one blow which can easily destroy a warship, the Forbes publication, citing expert Tony Cooper, reported that in reality, Russia does not have such weapons, and the demonstration is just a props.



“The Kremlin has announced a plan to equip the second regiment of the Air Force with MiG-31K interceptors, the first - and so far the only fighters compatible with the Russian Kinzhal air-to-surface missile. In fact, perhaps the MiG-31K and their very fast missiles are mostly for show. So far, the Russian Air Force's hypersonic rearmament program seems to have more flares than content. “All the information I get on this is not information,” said Tom Cooper, writer and independent aviation expert. Cooper said he had already heard complaints from Russian sources close to the development of the Daggers. "In fact, this is a show project demonstrating" advanced Russian weapons, "Cooper said," Forbes reports.

It is precisely the aeroballistic "Dagger" that is requested for the Tu-22M3, and not for the MiG-31. Probably, soon we will see such a missile carrier. "Twenty-second" was intended to carry the KR type X-22, he and a couple of "Daggers" will carry off. And the situation with the MiG, as I think, is just a temporary solution.
