TsAGI begins life tests of the second instance of the Il-112B aircraft

The second copy of the promising military transport aircraft Il-112В, assembled at the end of May this year at the Zhukovsky Central Aerohydrodynamic Institute, is fully ready for the tests, which will be held at a special stand.

As stated in TsAGI, the second Il-112V assembled in Zhukovsky will undergo a series of life tests aimed at verifying the compliance of real design parameters with the calculated ones. The aircraft will be used for static and dynamic tests and may remain at TsAGI for several years. According to the plans of the testers, he should not participate in the flight test program and can only be involved there if the construction of the third and fourth copies of the aircraft is refused.

Currently, the aircraft is checking and debugging the landing gear landing system, glider mechanization and airborne systems. After their completion, it is planned to conduct rigorous tests of the transporter, during which the aircraft will receive damage possible in production and operation. The next stage will be the dynamic and static loads corresponding to different flight modes, they will be carried out on a special stand.

Earlier it was reported that the resource tests of the aircraft will begin in July-August this year.

Recall that the second Il-112B aircraft was delivered at the end of December 2018 from Voronezh to Zhukovsky in a disassembled state in three stages. On the first - "stabilizer, flap, aileron, as well as dozens of containers with smaller parts" were delivered, on the second - sections of the wing of the aircraft, on the third - the fuselage. Transportation was carried out on road trains at night, accompanied by traffic police.

Work on the creation of IL-112V conducted with 2014 year. The Il-112B light military transporter is intended for the transport of personnel, weapons, equipment and other goods weighing up to 5 tons. In the future, the car will replace outdated An-26 and An-24 aircraft.

The first IL-112B model designed for flight tests took off on March 30 and made three flight circles with simulated landing.

This is what it means to sign an acceptance certificate on the Black Volga. This was a decisive factor.

[yehat]

But what about the design capacity and the actual mass of the aircraft?
Have enormous discrepancies been corrected?
it’s just that the first results were so bad that it was worth thinking about closing the project.

[maxim947]

Who was it worth? There was no talk about the closure of the project, beside someone else's sick fantasies.

[yehat]

the difference in load is more than 3 tons with the design 5 tons, is this normal in your opinion?
in a real sample that built a payload of not more than 2 tons
for such an aircraft, this is just a terrible indicator.

[maxim947]

And here is normal, not normal? , many have long known about this problem, even if in other numbers (up to 2 tons, not three), no one actually hid it, they have already reduced it by 1 ton on the first product. In general, they will eliminate it.

Do not know the history of the An-24? I advise you to familiarize yourself with "childhood diseases" in the first version of this aircraft.

Well, it’s like a rake passed, why else attack?
By the way, the question is how much better or worse is the scheme proposed by the Czechs without long landing gear

The first plane is always a stand. It is worked out certain decisions.

[yehat]

that's why I asked how the correction of problems is progressing, and they attacked me as if I consider them to be unrecoverable. But I remember that in one of the first interviews - excuses they promised to reduce the mass by 400 with a small kilogram.

Everything is fine. We have already found a way out to meet the TTX for the Il-112V, which suits the Russian Defense Ministry.

"It will take at least 112-8 months to finalize and redesign the Il-10V, so that the aircraft meets the tactical and technical assignment (TTZ) of the Ministry of Defense," the agency's interlocutor said.

As a result, a comprehensive plan to reduce the mass of the aircraft was approved.

The comprehensive plan provides for the replacement of secondary structures that do not affect the strength, rearrangement of the structure, the introduction of composite materials. As a result, only the first prototype of the aircraft will be with increased weight.

"We do not touch the load-bearing structure. And we fulfill all three main parameters - range, carrying capacity and airfield category. Only the very first machine," one ", will remain in the increased weight category," Ilyushin's chief designer explained.

[yehat]

Thank you, but this is not complete enough information.
What interests me here is that no one took the mass of the car seriously?
how could you be so wrong? And this is in the design bureau of Ilyushin, one of the most demanding machines in the development process!

[Sky strike fighter]

When in 2010 the fate of the Il-112V hung in the balance, they say that 3 departments from Il switched to work in Irkut (MS-21). And soon, the design of the IL-112V was continued by the young and early from here, and such a result, which is not without success corrected at this point in time to the desired performance characteristics.

By the beginning of May 2019, it was possible to reduce the weight of the aircraft by 2082 kg. Another 500 kg is planned to be removed during the modernization of the aircraft and the equipment complex, the transition to an electro-remote control system, optimization of the hydraulic system. This set of measures will allow you to get a reduction in aircraft weight by 2472 kg. All updates will be implemented on the next machine (0103), the appearance of which will fully correspond to all subsequent serial machines.

In addition to the airframe design, the TV7-117ST engine also turned out to be somewhat overweight. Its developer - JSC "UEC-Klimov" should reduce the mass of the motor by 90 kg, the corresponding work is underway. Until the end of the aircraft tests, the engine weight will be reduced.

The All-Russian Scientific Research Institute of Aviation Materials (VIAM) is also involved in efforts to reduce aircraft mass in terms of the use of new materials.

Of course, I am not an expert, but I was interested in this plane ... I wonder if a successful transporter turned out or not? Are there pilots on the forum? Just please, make it easier. Aviation universities, did not finish. :-)

[VO3A]

The plane does not meet the technical requirements ... It cannot lift the necessary load due to the fact that the structure is heavier ... Everything is being knocked down by the generation change and promises to eliminate, reduce weight ... Why should TsAGI conduct resource tests of a crude aircraft? Article fake depicting forward movement ...

[Andrei Nikolaevich]

Thank. In short, clearly.
One question only, the problem of generational change, reflected in the salaries of engineers and designers?

[VO3A]

Clearly, but not quite. The plane is very necessary, the ANs are falling apart ... The younger Rogozin was noted there and fled ... Everything did not affect the others ....

[Andrei Nikolaevich]

The first pancake is always lumpy. But to hope for the country's planes, pots and embroideries, is absolutely impossible! Sell! Let's hope...

why do you think this is the first pancake?
There were a number of projects before that. Here, on the forum, the specialist said that the IL-112 was so mopped up because all the leading experts were lured to another organization.
And youth is neither ear nor snout. It’s just a shame that a lot of money is wasted in training the ignoramus in practice. The jamb in the design is very large.
This is not just a lack of experience - it is simply not aptitude.

[Saxahorse]

Quote: yehat

Because the Soviet school of design has already ended. Thirty years passed, Soviet engineers died out. And the Russians are still not born. And since there was no normal generational change, they will learn from scratch, from their mistakes.

[yehat]

you underestimate the Soviet school.
there, all the work contained in the instructions. go through all the instructions (which is not easy and sometimes takes several years) and you will get the result.
the problem is not in it, but in the fact that optimizers want to get around it

[RideMaster]

Why is it needed. What task can he perform in case of war. What in general? Dragging somewhere a platoon of specialists, there will be no nearby platoon of specialists 50-100 km away, who will get under their own power and with equipment?

[yehat]

in war, sometimes 1 soldier who is in time in the right place is stronger than the regiment.
therefore transport is very important
catastrophe of the Red Army with gigantic losses near Rzhev could not have happened if the Germans were late to transfer one incomplete battalion for only half an hour

[donavi49]

Someone really liked Spartan and TK wrote +/- similar. Well cut out refueling in the air. Range optimized for Russian realities. The plane itself was stung by 1 / 3 by weight - for there are no engines like Spartan. However, philosophy itself is not a replacement for AN, but a significant expansion of the list of transported goods, including armored vehicles, due to the volumetric cargo compartment (this is the main feature of Spartan - the 2 engine, but it fits almost everything that fits into Gerkula).

But it turned out so-so. Not only is the design bureau not very attractive for money (at the level, all the coolest ones have been dumped in Europe and China, those who stayed in Irkut, Sukhoi, and the third grade is not a marriage in Il and Tu). So in the design process, the aircraft was suspended in production and financing, the team has changed several times. Irkut bought a whole department simply to strengthen work on the MS-21 in one of these windows, when it became foggy again on the Il-112.

The result is a serious drag and now they are struggling with all their might. The aircraft at the moment does not meet the specified characteristics very significantly. But they promise to straighten everything in the near future on new flying machines.

For BTA, the aircraft is in principle necessary, although the question of transporting which Tiger is very controversial. If that Spartans sold fewer 100 cars. There are competitors (in +/- the same weight) from CASA (now Arbuzik) - with a narrow fuselage where the machine will not fit, but economy, load capacity = more 400 cars and many orders. That is, IL-112В is unlikely to be successful in the global market, because the competitors are strong and they do not sell much (Arbuzik pushed Leonardo more than 4 to 1).

Why should TsAGI conduct a resource test of a crude aircraft

as I understand it, the loaded parts will not change and they can be tested in the form as it is now. Only from the stories did I understand that the IL-112 has problems not only with the mass of auxiliary elements, there are questions about the performance characteristics of engines and significant differences in the mass of electronics and their declared characteristics (for example, increased requirements for the accuracy and stability of power supply parameters)
I still can’t believe that the hump on this machine has been aerodynamically made.

Hump ​​- not made for beauty. This is the center section and brought it to the top of the fuselage so that it does not occupy a place in the cargo compartment. On many high-flying transport aircraft, such an element is present.

"The first sample of the Il-112V, intended for flight tests, took off on March 30 and made three flight circles with a simulated landing."
But he didn’t sit down ... Everything flies ...
Do not kick me, this proposal I did not build that it is so clumsy. TRAINED JOURNAL ...

According to the new state armament program, they want to buy 100 IL-112V. As far as I remember. I am more interested in the IL-276 project, the technical assignment for which is approved. It is not necessary to put the PD-14M 15,6 tons of traction on it, you can put the PS-90A3M 16 tons of traction. The cabin seems to be from IL-76MD-90A. The car you need.

[Piramidon]

Quote: Sky Strike fighter

This is a different weight category.

[donavi49]

Necessary, but not pulled on profitability. Moreover, the main customer dropped out (India).

It’s just that while IL-276 doesn’t even have a finalized layout - the main competitor received a type certificate, started mass production and expanded under the Boeing’s wing (Portugal already bought, Algeria would buy - if it weren’t for the political crisis with Buteflika, a number of countries are being courted, and Boeing has become much easier to walk around).

Well, that is - native VKS 50-60 aircraft will be ordered, another 20-30 will be sold. And do not even go to zero . Again - if you look at Spartan, which was shoved by everyone, even Lockheed was involved in lobbying, and the result is less than 100 cars.

[Vlad.by]

When the mass glider and traction characteristics of the engine are brought to TTZ - there will be no price for it!
And there, you look, and Klimov with an advanced engine will catch up, so that it is even more thrust and more economical with the same or a large resource.
And 112 will take out, and the 114th will help. Both need Russia like air.

[Sky strike fighter]

By the way, it became clear why the production deadlines for PD-14 were shifted. "Partners" "helped" at the most crucial moment. When will we initially rely on ourselves, otherwise we are tired of walking around the rake.

"In accordance with the plan for import substitution of components and materials for the PD-14 engine, instead of Japanese carbon material for the manufacture of reversing device grids, domestic material produced by UMATEX was selected. In 2019, a set of measures is planned to introduce this material into production. . the start of serial production of grids from domestic carbon fiber is planned, "the corporate magazine" Perm Aviation Engines "writes.

https://www.vestifinance.ru/articles/123290

[yehat]

strange, I can say firsthand (Toyota Hank technical center and representatives of Mitsubishi, a technological university) I know how the Japanese are persistently looking for niches for selling modern materials. To do this, they have a whole network of superbly equipped workshops and laboratories that are idle. There are workers, but there is no sales and they incur losses. Failure to sell materials to us is unusual.

[Sky strike fighter]

Neither Japanese nor American counterparts need a competitor in the face of the MS-21. I feel that until we bring the share of domestic components to 100% in the MS-21, this aircraft will not really go on sale. Only the SSJ-75 is 100% from domestic components. we will be able to sell to Iran. And we need our own engine for it. Otherwise, we will not cook porridge with the "partners". Whenever it seemed that there was nothing to interfere with serial production, the "hand of the market" appeared out of nowhere, imposing new sanctions, new bans.

[yehat]

perhaps DARPA is working here together with the CIA, cutting down the logistics of promising industries.

[Nycomed]

I am not an expert, but is it really impossible to carry out these tests directly at the factory? The fact that the entire Anov park should be replaced as soon as possible: this is unambiguous, until they began to crumble in the air from banal old age. But there are still many questions.

Can someone tell me why the comments on the site are mainly about "everything is gone", bloggers are sophisticated in their wit for any reason. We started testing the second copy of the aircraft and all the information, why so much outright sarcasm, maybe someone just wants to show their awareness, despite the fact that there is no reliable information?

not so simple . Have you read the changelog? For example, hydraulics are changed to electrics.
and another question is whether everything that has been facilitated will be rolled.
I’m sure that the plane can be brought to mind, but I’m far from certain that there are necessary personnel for this.

[itarnmag]

They cannot, sorry for being rude, design a lousy transporter with a capacity of 5 tons, but they are going to design PAK YES

[Sky strike fighter]

They designed a light military transport aircraft with a carrying capacity of 5 tons. What can not? They will be put into the required performance characteristics in a year. They launched the IL-76MD-90A with a carrying capacity of 60 tons into serial production.

high planes such an element is present.

Yes, it’s present, only the inlet shape in front of it is completely different - much closer to the drop-like shape and here it’s just a flat bevel. Do you understand that this is a ready wing?

Meanwhile, the assembly of the first Il-114-300 unit was completed at VASO:

[RideMaster]

But I really don’t understand the need for such an aircraft. What can he transport somewhere urgently this? Where can an extra platoon be sharply required?
In my opinion, silt 76 in a situation where a couple urgently needs to be dragged by the best option and plus with equipment.

[Sky strike fighter]

Transportation of light cargo, cargo up to 5 tons, for which the capabilities of medium and heavy transporters are unnecessary.

It's like with a Gazelle - you can carry a load on a 10-ton truck, but it doesn’t go everywhere and you don’t always need to carry so much.
