Russia assembled a gas generator for the giant PD-35 aircraft engine

This promising aviation the engine is considered the largest of all recently developed in our country. Now in Russia they have assembled a gas generator for such a giant aircraft engine PD-35 (35 tons - thrust parameters).

This was reported by the press service of the state corporation "Rostec".

The generator for the new aircraft engine is now being bench tested. According to Alexander Inozemtsev, general designer of UEC-Aviadvigatel, the enterprises where this unit is developing should show how efficient it is. In addition, the tests are supposed to take measurements, determine the main parameters of the components and compare them with those stated in the terms of reference.

The design of the gas generator, which is called the "heart of the engine", includes a combustion chamber, a compressor and a turbine. Its elements are designed to work under high pressure conditions.

Upon completion of work on the PD-35 aircraft engine, it is going to be installed on wide-body passenger aircraft intended for long-distance flights. The United Engine Corporation, which is part of the Rostec structure, has been developing it since 2017.

Well, the process of creating PD-35 is now in the middle of its journey. The engine began to be created in 2016 and should be completed according to plan in 2026.

Curiously, what is the fate of the Kuznetsovsky turbofan engine NK-93 now?

Why do you care about his fate so much? NK-93 is retired. Although the prospects were not bad, new projects have come to replace him. PD-14 and engines based on its technologies.

.At the time, A.A. Inozemtsev wrote that he did not consider the NK-93 project innovative, since the technologies and design methods used belong to the past century. That's right, but for some reason the consumption characteristics of the old man NK-93 are better than those of the innovative promising PD-14, and the customer does not care what methods were used, the fuel consumption and the cost of the product are important to him.

The new PD-14, in comparison with the older brother PS-90, really gives out the best indicators in fuel consumption, in cruise mode this parameter is 0.54 kg / (kgf / h), versus 0.595 kg / (kgf / h) for the older brother, but PS-90 this indicator is the largest in its class.

And here are the reviews from the "Argumenty Nedeli" edition about NK-93 in 2011:

“After testing in the air in one of the modes, the NK-93 produced a thrust of 20 tons, and it was believed that this sample could not have more than 18 tons. The pilots were surprised - the thrust is one and a half times more than that of the PS-90A, and the fuel consumption is one and a half times less. NK-93, which has no analogues in its performance, showed high performance during flight tests in 2007. The bypass ratio is at the level of 16.7, and the specific fuel consumption was 0.49 kg / kgf / h. "
Maybe the PD-14 is at least cheaper than the PW1400G - but no, its price is about $ 6 million, and for American engines - $ 5.4 million. It is assumed that for the first customers of aircraft with Russian engines there will be a 15-20% discount.

And one more curious difference, in theory, modern materials are used in the design of the PD-14 and it is made using the most modern technologies, which means that it should produce more thrust per kilogram of its own weight than that of the old NK-93. In fact, the specific thrust for the modern PD-14 is 4.878 kgf, and for the outdated Kuznetsov engine it is 4.93 kgf. But if the NK-93 thrust is fixed at 20 tons, then the specific thrust will already be 5.479 kgf. But the NK-93 fan can still be significantly lightened by placing blades made of epoxy graphite-plastic.

It is unlikely that NK-93 is needed now. The stake was made on other projects.

The designers assume that they will easily increase the thrust of the Samara engine to 23.5 tons and this will allow equipping the An-124 with such engines. For the Il-96-400, it is safer to have four NK-93 than two PD-35s, and their outer diameter is about 4 meters, and this is fraught with contact with the concrete of the strip.

I believe that both PD-14 and PD-35 will be useful for Russia, and it is also not worth abandoning the NK-93, because the more various developments we have, the more competitive the domestic engine building becomes, and with it it becomes more and more interesting and Russian passenger airliners are more attractive.

NK-93 showed much better results even with the "old" technologies, and if it had been used with modern heat-resistant materials, higher temperatures on the turbine, lightweight propellers, its superiority would have been even more striking. In addition, it showed significantly lower levels of noise and emissions than are laid down in the current standards.
But the topic was closed. Closed even before Medvedev closed the domestic civil aircraft industry. At the request of partners, both Boeing and Airbus.

[Eug]

With a thrust of 18 tons. diameter of NK-93 is 3150 mm., for PD-14M with a thrust of 15.3 tons. diameter 1900 mm. For an aircraft, this means a significant reduction in Cx and all the associated benefits. Perhaps the reason is not only corporate rivalry, but this too. This is where (and not only here) an objective arbiter is needed ...

[Grossvater]

Too optimistic. The cycle of creating a modern engine can hardly be less than twenty years. On the other hand, some work must have started much earlier. In general, very good!

[Archon]

And when its development is completed, will subsequent developments be faster or does it not affect in any way?

The creation of a demonstration gas generator and a technology demonstrator engine is necessary for the development of design and technological solutions to confirm the readiness of new technologies for use in the design of advanced engines. The developed gas generator will later become the basis for the creation of engines in the thrust range from 24 to 38 tf. The development of engines in the thrust class from 24 to 38 tf will be faster, since they will rely on the PD-35 technologies, as the creation of the PD-8 engine is going faster, since the technologies used in the serial PD-14 were used in its creation.

[Archon]

Thanks for the explanation, as the development time looks depressingly long, although they write that this is the norm.

[Orange bigg]

The gas generator was assembled back in September.

... On September 15, 2021, the assembly of a demonstration gas generator of the PD-35 engine was completed at the Perm JSC UEC-Aviadvigatel. The gas generator was installed in an enclosed test bench and is being tested under standard atmosphere conditions in accordance with the approved program. This was reported by the press service of the United Engine Corporation.

On October 1, 2021, the idle mode was reached, the stable operation of the units and systems of the gas generator was ensured.

According to Alexander Inozemtsev, Managing Director-General Designer of UEC-Aviadvigatel JSC, the tests should confirm the fundamental performance of the gas generator design. Based on their results, it will be possible to evaluate the parameters of the nodes laid down in the TK.

The next stage of testing will take place at the Central Institute of Aviation Motors. P.I. Baranova. As part of the second stage of testing, the operation of a demonstration gas generator will be tested with heated air under pressure supplied to the inlet, which simulates the operating conditions of the unit as part of the engine. At the moment, a specialized test bench is being prepared at CIAM.

The creation of a demonstration gas generator and a technology demonstrator engine is necessary for the development of design and technological solutions to confirm the readiness of new technologies for use in the design of advanced engines. The developed gas generator will later become the basis for the creation of engines in the thrust range from 24 to 38 tf.

And where are you engines with a capacity of 45 tf. with a pizza for 55 tf. put it together, on which plane?

For a start, on the IL-96. But it is also necessary not to forget about the new generation of ekranoplanes: at least a destroyer must be taken off the water.

IL-96 is waiting for these engines. Two instead of four.

[Kurare]

Is there already a project of the 96th with two engines? This is the option when creating a new one is cheaper than reworking the "old" one. In addition, the conception of the 96th is still a project of the 70s - 80s. Those. nearly 40 years.

Do not fantasize.
He doesn't expect anything.
There are no planes in the history, developed for 4 engines and remotarized for 2.

Even the 8-engine B-52, which could actually be remotorized to 4 engines, was left with 8 engines replacing the 1-in-1 engines with commercial Roll-Royce engines.

[Grandfather]

mmmda ... "product 30" for the 57th is still tortured ... and this project has a very vague future ...

[Zaurbek]

It's not even about the turbojet engine ... the heir of Il96 himself has a hazy future ... if there is a niche in the MS21 and SSZH within the country, then the SHFS has a small one, there are not so many of them purchased from us. But, maybe, such a turbojet engine will go to industry, energy, the fleet ...

Unlike Il96, there is no need to save grams ... and PD-14 begins to be produced, which will probably be transferred later ... with the next modernization.

It's already worth it.
Military aircraft, during their peaceful operation, consume ten times more resources than the purchase cost.
Accordingly, the whole world is already putting on its BTA aircraft - namely commercial engines.

1. PrattWitney 2000 series stands on both civilian 757 and military C-17. It was planned to be installed on the Il-96M.

2 GE of the SF-6 series, stands on a huge pile of civilian airliners, as well as on the military S-5, KS-10, A330_MRTT ..

The Lancer has the same engines as the F-15/16.

Well, I could call A330_MRTT - which is a universal platform.
Transporting up to 380 soldiers.
Up to 60 tons of cargo in NATO standard containers with incomplete refueling. And with a full refueling of 110 tons of fuel, it carries 45 tons of cargo.
The only thing that will not uveh to haul equipment is that there is no ramp.
And yes, 2 engines.
and its maximum takeoff weight is 10% more than that of the Il-76MD-PS-90

Think correctly. TTS "Elephant".

... And here, to replace the An-124 "Ruslan", the development of the newest Russian heavy transport aircraft "Elephant" is already in full swing. If you look at it visually, then it does not differ much from "Ruslan". But still, technically this car is more perfect. In addition, you need to understand that the "Elephant" is not a modernized copy of the "Ruslan", but a new car. The aircraft project was first shown at the MAKS-2017 air show. TsAGI (N.E. Zhukovsky Central Aerohydrodynamic Institute) is working on the aircraft project.


Some of the most important characteristics of the aircraft are already known. For example, the Elephant's cruising speed will be 850 km / h, and the range is about 8 thousand km with a maximum load of 150-180 tons. That is, we understand that the aircraft will surpass the An-124 Ruslan in terms of carrying capacity and flight range. And this is a very serious claim for the championship, especially since the plane will become a leader, if it is created in reality. Externally and in general in terms of layout, the aircraft will resemble Ruslan. It will have one tail fin and elongated wings. The wingspan will be 87-88 m, and the wings themselves will have folding tips for easy parking and cargo loading and unloading.

... Four Russian PD-35 turbojet engines will be installed on the pylons under the high wings of the Elephant. These engines are promising and are at the stage of deep development. The landing gear of the aircraft is also impressive. On each side, 7 landing gear legs will be installed on two sides, for a total of 14 legs. In the bow, two controllable supports will be installed. In general, it resembles the chassis of the good old An-124 Ruslan. The entire length of the fuselage will be occupied by the cargo compartment. It will resemble the An-124 Ruslan compartment. Like the An-124, there will be nose and tail loading ramps. The nose section will fold up. It will be possible to install an additional deck in the cargo hold of the aircraft.

The Elephant's flight range without fuel and with maximum fuel load will be 18 km. With a load of up to 180 tons, the range will be about 5 thousand km, and with a load of up to 150 tons - about 8 thousand km. In any case, a huge advantage of this promising heavy transport aircraft is that for takeoff and landing, it will need a GDP of no more than 3 km in length. Naturally, the aircraft will be equipped with the latest avionics according to all international standards and a welcoming modern comfortable cockpit and a cabin for the crew and personnel.
