On the promising Russian-Chinese heavy helicopter can install engines from the UEC

Vladislav Masalov, Director General of the United Engine-Building Corporation (UEC, as part of Rostec), said at a press conference that the possibility of equipping a promising Russian-Chinese heavy helicopter with an innovative PD-12В engine, created on the basis of a gas generator of a turbojet engine (TRD) PD- 14 for the MS-21 civil aircraft.

“In June, in the framework of the meeting of the working group on aircraft building, which was held by the Ministry of Industry and Trade of the Russian Federation and the Ministry of Industry of China, the issue of organizing work on the creation of a new installation was discussed. We can offer such an engine based on PD-14 (PD-12В), ”he said. TASS.

The head of the UEC stressed that work on the power plant will be conducted in parallel with the design of the helicopter.

“Last December, we carried out a prototype fitting (gas generator) PD-14 on the Mi-26 - it fits, this is an additional plus. Of course, we also have an old, proven engine, in particular, the second D-136 series. But the creation of a new power plant is a more promising direction, ”he noted.

In addition, Masalov gave comments on the creation of a center for the production of rocket engines on the basis of the enterprise OAO Kuznetsov (Samara), stressing that this would be inappropriate.

Kuznetsov consistently produces about 25 rocket engine packages (about TASS annually), which is approximately 40 percent of sales volumes. We do not see any failures and risks in the organization of this production. At the same time, the company fulfills agreements on the production and repair of NK-32 engines to equip the Tu-160. From this point of view, the situation in Kuznetsov is stable. I would not consider the creation of such a center in the medium term. I do not see the expediency of this measure, ”he added.

Something scares me the wording to convey the innovative engine ...
And, what is not innovative we can’t convey ???

Will they take it? Now there is a crisis, and China is a rich partner with a gigantic market, if there is no normal supply from us, a long queue will be formed of those who want to cooperate.

[crazyrom]

The people who understand a little, explain: what is the big difference between aircraft and helicopter engines? It seems both turbines ... Maybe a helicopter can somehow direct the nozzle back to help in the forward movement?

I kind of already read somewhere that the PD-14 is much inferior in thrust and bypass to the Amerian PW1000G Pratt & Whitney engine. In PD-14 7,2-8,5, the bypass ratio of amers PW1000G is equal to 12. Do you have any specialists? Can they explain what our miscalculation is, or maybe on the contrary we jumped over amers? The truth is there is little faith.

Then they would buy engines from us for airplanes, but at the moment everything is just the opposite. Their engines are still much better - more economical and quieter.

The PW1000 engine is a turbo-propeller-fan engine (TVVD) and the PD-14 is a TURBO-FAN (TVD).

You can increase the bypass ratio only by reducing the fan speed, otherwise it will break. Therefore, the PW1000 has a gearbox in front of the fan, while the PD-14 does not have a gearbox.

PW1000 is a new generation of engines; a high-pressure fuel pump is much more economical and can be a bit more powerful than a similar fuel engine. Maybe only the speed of the plane will be slightly less.

We tried to create something similar - this is NK-93. But they did not finish it.

[Maxom75]

Then why not develop the most promising TVVD, instead of a well-known junk? I understand that there have been no developments in this area, but if you do nothing, then nothing will happen! Or am I wrong? I read something else about the new development of detonation rotary engines in the UK, but do we do something in this area or will we catch up again later?

Well pd-xnumx is not junk. This is a new engine - a replacement for the PS-14. PS-90 is the trouble of our entire aviation industry. And it must be replaced first of all, and for a long time! For our aviation industry - this is likely to be a breakthrough, for the world definitely not!

There is a prospect of creating PD-18r. this is a variant of PD-14 with a gearbox - just a high-pressure fuel pump. But I think this is a very distant prospect, to survive.

The problem is that we do not have gearboxes. The greatest in this sense is the MI-8 gearbox. since then, our industry has failed to create more or less reliable gearboxes with a large resource.

Well, there are patents on this subject. I once heard that Saturn is studying something similar. But aviation is very conservative, as security is needed. I think we will not live up to these engines ... It's more like a romance for now, maybe I'm wrong.

[Maxom75]

Thanks for the detailed answer. But the problem of gearboxes cannot be solved by the old Soviet system? In short, they stole the best from others, finalized and launched it as their development?

Well, production technology is not so easy to steal. Otherwise, for a long time it was possible to make Lada Mercedes.
For example, the Chinese cannot make Al-31 turbine blades so far, although they do the rest

We have already got the wording, such as "may" ... They may or may not ... When it is already developed and delivered. All the rest - give me money, then we'll see, maybe we'll do it ...

[Maxom75]

Dad can, dad can be anyone, only he can’t be a mom. So it is with us: give money, give money then maybe we can, well, and if we can’t give it anyway!)))

[otter]

I have a question for the respected SSI, and what MI-26 does not meet the requirements, what is it for? new "promising"?

[FID]

So, they just used the parameters of a heavy helicopter to break in a new gas generator ...
and "new, promising" is "give me money." Together with the Chinese - it means "no money, look for yourself" ... I think it's something like that.

[Maxom75]

I just don’t understand why the Mi-26 is bad? Why make another niche product? Making competition? Did the Mi-26 not suit the Chinese?

I think the two-crew version should suit everyone. Only Ukrainian engines there - now this is a problem

[Maxom75]

Well, here I am, is it worth it to fence a new garden? If the Chinese want to assemble helicopters, deliver assembly kits to them and let them assemble them under our supervision. Formally, the helicopter will be of Chinese assembly, but in fact our country will be the beneficiary.
