I wrote about the timescales because it seemed to me that some users thought other projects (including the il-276) could be ready within a couple of years.
Nobody knows the work that is or is not being done behind closed doors and the urgency of the work is directly related to the current situation... where civilian airliners are a higher priority as the existing An-12s and An-24s and An-26s and An-72s and Il-76/476s can get the job done even if it is not ideal.
A modified Il-476 is the fastest solution to the replacement of the An-12 in the form of an Il-276.
An Il-212 might reduce the requirement for the Il-276 by replacing the An-12 and An-72 and An-26 in a lot of roles, but in the longer term they might find an aircraft to actually replace the An-12 is needed.
As far as the il-112v, it had a wrongly designed (and manufactured) wing, a wrong weight distribution and probably there were other issues.
But otherwise it was what they wanted.
All new aircraft have issues and changes that need to be made... that is normal.
If the Russian airline industry had supported their domestic designers and producers these things could have been sorted out decades ago... instead they will have to wait.
Buying Chinese or Brazilian aircraft is just continuing their original mistakes...
They were trying to solve them (the prototype who later crashed needed to carry also a lot of "ballast" in the front in order to be airworthy, which limited further its payload), but the only way to fix them, without doing some sort of temporary fix and compromising anyway its performance would have been anyway to go back to the drawing board and recheck also the requirements.
So while they are adapting the design for the PD-8 engines in the Il-212 model they will get some experience and time to do so.
They tried as much as possible to salvage the project, but at the end what they can salvage will be the experience, some lessons learned, some design concepts and some of the subsystem designs
All they needed were more powerful and more reliable engines and from the comments about the Il-114 they have it. The Il-114 is going ahead with unreliable engines you are claiming? The power rating was 4,500hp wasn't it? That is plenty for the Il-112 as it was.
Now they are making the Il-212 with PD-8 engines they don't need the Il-112 to carry more than 5 tons... that was what they wanted it to do. It just needs to take over from the An-26... there was no requirement for the Il-112 to replace the An-72 as well.
As far as the TVRS-44 Ladoga, this "Czech design with Antonov modifications" is a high wing airplane (as the An-24) and has been selected by Russia as the An-24 successor. It will cover a slightly different niche than the 68 passengers il-114 (which is a low wing airplane).
The high wing is mainly for cargo planes. Low wing for passenger planes. Did the Russian military select the Ladoga?
Then why would they waste time with the Il-212 when they have selected the Ladoga... surely PD-8 engines on the Ladoga would make more sense for a cargo plane.... continuing the Il-112 in the form of the Il-212 makes no sense if they are never going to go for the Il-112.
BTW the Ladoga uses the same engines as the Il-112 so how could it be acceptable?
It is not a proposal from just from UZGA, it has been confirmed from russian state officials. The civilian turboprop will be produced in decent numbers.
For civilian use... but what is the military choosing?
The military cargo modification is just a proposal, but it is a easier starting point.
So not actually happening yet if ever.
And since the An-26 was a military cargo derivative of the An-24, I thought that it would not be crazy if the An-26 successor will be a derivative of the An-24 successor.
But if the military transport plane is the Il-114 then surely the military cargo plane would be Il-114 based too.
As far as its engine, 2400 to 2600 hp (for the TV7-117ST-02) are perfectly adequate for an aircraft of that size with about 5 tons payload. If more power is needed they could use the TV7-117ST-01 of the il-114 which can be rated between 2800 and 3100 hp at max takeoff power).
It was reported above that it is running at 4,500hp on the Il-114 which should be plenty for the Il-112 as well... but the Il-212 could replace all of them and the An-72.
It was not enough, however, for the il-112V because of the larger fuselage and wrong aerodynamics.
The larger fuselage was obviously required... everything that is offered to replace the Il-112 will have to have the same fuselage expansion too to also meet the customers requirements.
Anyway, to have a turboprop aircraft with the desired characteristics (increased payload and larger cargo bay than the An-26 / TVRS-44T) they need to wait until the new engine (probably the PDV-4000) will be ready.
They are making an An-72 replacement which has been likely doing the jobs of the An-26 as they retire, why do you think they need the Il-112 now?
In 5 years time is fine.
caused a temporary stop to such project, so I doubt it will be certified before the end of the decade.
So.
It is not a critical priority that will collapse the Russian military if it is not replaced right now.
Just that it has a cargo bay 3.33 m wide and 2.60 m heigh, and has a payload of about 11 tons with two 4600 hp engines.
The AN-22 has a much bigger cargo bay and much better payload and the engines for the Bear have been massively upgraded.... but if they wanted to they could fit the propellers for the AN-70 on the Tu-95 engines to get a monster power plant that is currently in production...
They are working on the designs they need and when they are ready they will start producing them. Why is that so hard to understand?
The il-112v, even with a much narrower cargo bay (than the C-27J) would have needed at least two 4000 hp engines just to hope arriving to 5 tons payload.
Its cargo bay is bigger than the aircraft it is designed to replace. The fact that it is smaller than the C-27Js cargo bay is irrelevant... perhaps an Il-076 with PD8 engines and shrunken fuselage and wings for the An-72 replacement role is the better solution... that way from the An-26 all the way up to the Il-476 it has a bigger cargo bay.
You have been saying you don't like the plane (ie-112) for a while now and you would prefer an 8-10 ton payload aircraft be made instead... what do you think the Il-212 is going to be... and yet you are still complaining.
You don't like the Il-76 either so you reject the Il-276 too.
That is OK, I understand. But moving forward the Il-212 is happening so the Il-112 becomes less urgent and possibly irrelevant... which makes a Ladoga replacement irrelevant too.
The Il-114 is happening too making a Ladoga for the Russian military unnecessary... the Il-114 can easily replace the An-24 and the Il-212 will replace teh An-26 and An-72 in one hit.
Modifications to the Let plane no longer required.
And the cargo bay of the il-112v is just 20 cm wider than the one of the An-26 (2.42 vs 2.2 m) (its only real advantage is the cargo bay height),
The point is that they changed the dimensions. That was not to increase drag or reduce performance... it was clearly intended to effect the type of internal cargo the aircraft could carry based on operational experience.
which with 2 turboprop engines with max takeoff power of 2800 hp had a max payload of 6 tons.
Except they were talking about hp of 3,500 to 4,000, and 6 ton payload to replace an aircraft that could carry 5 is clearly what they required.
You do understand nothing comes for free. The extra power and size needed to carry 10 tons makes the aircraft more expensive and rather inefficient if it only ever takes payloads of 5 tons or less.
No, of course not
The resource inherited from the Soviet era must be used to the maximum of its useful life, specially in wartime
Perhaps you are not understanding what I am saying... making Soviet stuff the first to go does not mean immediately discarding it and having nothing.
It means using it up but not replacing it with more of the same. Replace it with new stuff or Russian stuff your Russian companies own all the IP and rights to that is not contested anywhere these planes might operate now and in the future.
In addition to building the Il-76MD-90A and modernizing the remaining Il-76 and An-124, the industry was destroyed in the 90s and cannot be rebuilt in a couple of days, workers and engineers must be retrained
Understand and agree... but the An-124 factory would be better utilised upgrading and russianising current An-124s and An-124s in storage rather than building brand new An-124s when their new engines wont be produced till 2027....
The An-124 factory would be better used to upgrade and overhaul existing aircraft and also build some prototypes of a two engine and four engined replacement for the An-124 so development can get started sooner rather than later. Production of a dozen pre serial production PD-35 could be tested and used in prototype aircraft to speed development.
They have An-124s in storage so they are clearly not getting overly used and as more Il-476s enter service the demand for heavier aircraft might reduce too.
Once this is done, start with new simple models, from the lightest and simplest segments and after 10 or 15 years make larger and more complex aircraft to begin replacing the Soviet ones
Which is all I am suggesting over a slightly shorter time scale... the work on the PD35 seems to be progressing well with few problems... which is impressive for such a powerful engine...
We see the same with aircraft, relaunching the construction of the Tu-160, investing in the industry, getting qualified personnel and then moving on to the PAK-DA.
The Tu-160 is not obsolete and was needed in greater numbers to become a viable fleet... if it was that serious to have heavy transports they could have put the An-124 into production with the An-22/Tu-95s engines as a stopgap An-22 replacement... why not?
Perhaps even fit 6 engines instead of four?
And the same goes for ships, it doesn't start with nuclear cruisers and aircraft carriers, but with corvettes, minelayers, etc., then frigates and LSTs, etc.
Well that is ironic as you suggest starting An-124 production at a time when the Il-112 and Il-212 are not being produced... so the opposite really.
the 3 An-124 in Leipzig and the An-124 in Torono, have been illegally KIDNAPPED
They have, you are right... and why do you think they would look at a brand new all Russian made An-124 and say... well we can't steal that and give it to Kiev... they will take any Antonov in Russian colours they can get their hands on.
Russia can build whatever it wants, Russia has not recognized Ukraine as a state since February 22, 2022, therefore it applies the law prior to December 1991
They can build what ever they want, but why keep alive a dead Ukrainian company when Russian companies will have designs and projects that Russia can fund and produce.
It might take 10-15 years to get something ready for serial production after the engines are ready but what is the rush?
Restore and Russianise the Soviet planes you have and use them till they become unsafe to use and by then produce the Russian designs you developed in that time.
Those engines seem to be already already high enough to handle landing on dirt
By putting them above the wings the chances of dirt and rubbish being sucked in is massively reduced plus the interaction of the engine exhaust and the wing surfaces allows the thrust to be vectored downwards adding to lift effect and improving STOL performance... as shown on the An-72.
AVIASTAR is going to be very busy. The number of Il-76s needs to be increased to 250 units, which means building about 100 more plus some versions and modernizing several dozen Il-76MD-Ms.
If they decide to make the Il-276 that would justify another factory which could make either type because they are the same aircraft but with bits added or taken out of the fuselage and wing. It would mean if you needed more Il-476s you could temporarily stop Il-276 production and produce extra Il-476s for a couple of years, or vice versa...
Are there any chances they will modify Tu-214 and Il-96 for military use? (AVACS and tankers)
They are straining to make as many as they can for civilian airlines, so military conversions will have to wait... but eventually there are going to be lots of Tu-214s around and a significant spare parts market and some factories that used to make civil airliners who don't have orders that the military could take advantage of to replace some older types in the military like the Il-20 and Il-22 and the Tu-154M and Yak-40 and Il-62 and Il-38. Of course some of those aircraft could be replaced with Il-114s and other types as well.
There will be no new heavy aircraft before 2040, and it must be like the An-124, which has a cargo hold of 36x6.4m
Anything smaller makes no sense. It is not a question of weight, the An-22 was 33x4.4m, which is not very wide
A Slon can be any width and height they want and is not limited to what the An-22 or An-124 was in the twin or four engined model.
Manufacturing a new version of the An-124 is not at all unusual, the Boeing 747 is from 1969 and the Wolfswagen Golf is from 1974
If it needs to happen then it can happen... but when the PD-35 engines are ready it makes no sense to fit them to the An-124 because they are way too powerful to make sense... like putting a V16 engine in a mini cooper.
All the VKS An-124 are soviet made (last in 1990) and i beleive all the Volga-Dneper an-124 were made in Aviastar most in early 90´s without foreign parts
Tell the western pirates who seized them and they might give them back.
That's not going to happen, all PS-90 engine production will be for the Il-76MD-90A between now and 2040, at least 100 have to be made, probably more with the versions, and many more for export to India, Palestine, Iran...
The Il-276 is a modified Il-476 so any factories added to make Il-276s could also make Il-476s if required... they are the same plane with a shorter fuselage and wings and a different number of engines...
Even if the Russian military does not need or want an An-12 replacement there are plenty of customers world wide that would appreciate them... especially with their commonality with the Il-476 which is also likely to sell well when made available.
The Il-212 will be the one to do all the regional transport in the VKS, planes like the An-26 for logistical reasons do not make sense, in the USSR there were hundreds of regiments with several air bases very close to each other in all the provinces.
And yet the An-72 never replaced the An-24/26... because for commercial operators it burns more fuel and costs more to maintain and operate.
The engine for the Il-112 was not chosen by accident... it will be widely used and is simple and cheap to work on. Propeller driven aircraft continue to be used commercially because they are much cheaper to operate and support even if they do fly a bit slower.
Nowadays it is better to do a single flight A-B-C-D-A than three flights A-B-A, A-C-A and A-D-A with three different planes smaller airplanes
Even with the higher flight speed that will take longer for one plane to visit those locations compared with three planes all flying at once. The first delivery will be efficient, but as the loads get lighter it becomes less efficient to use a heavier jet powered aircraft.
Maybe there are two Il-212 variants with PD-8 and PD-14 but I don't see why you want to lift more weight if you don't have more space to carry more pallets.
Scaling up creates problems... like the Ivan Gren river boat trying to be an ocean going landing ship.
The obvious problem is that if they used AN-12s instead of An-26s because of cargo bay volume or even Il-76 instead of An-12 because of cargo volume then designing a plane to replace the An-12 that is only slightly bigger cargo bay wise than an An-26 is the wrong way... it makes more sense taking the bigger cargo hold of the Il-476 and making it shorter with fewer engines and smaller wings but the bigger cargo bay cross section.
You can then use the Il-276 when otherwise you had to get an Il-476 for the height or width.
The Il-212 and Il-276 make sense to replace An-26 and An-72, and An-12 aircraft respectively and if they build a factory to make Il-276s and they only make 50 for domestic use that factory can start making Il-476s when it has finished production of the smaller aircraft, or can make the smaller aircraft for export if there is demand.
Export aircraft are going to make good profits for the factories and help them pay off their debts quicker...and the Russian military does not even have to buy a single Il-276 if they don't want them.
If they make an Il-212 that can carry 4 standard pallets, that is the same as the short C-130, although with a little less weight each pallet
There is no reason why they can't make it longer with all that extra power... an extra 3 tons thrust over the An-72.
Anyway restart production of the D-18T engines will make less sense if they do not restart also aircraft production.
Well it could be similar to the restart of production of the Tu-160. If they have designed the engine production factory to be a modern state of the art factory for making engines of potentially any type they could start by adding up all the An-124s that are in use and storage and make a couple of extra engines for each aircraft and make that number of aircraft engines... and when they have finished that start making PD-35s and other engine types they require in ever increasing numbers then it would make sense.
How many brand new An-124s would they actually make?
A dozen?
They are not going to need hundreds of them, and considering the purpose of the PD 35 engine is for their next generation transport planes making lots of An-124s is a huge step backwards. in money wasting and time wasting.
- The most under-utilized plant is Aviakor in Samara. It produced over 1000 Tu-154 planes in the past. It certainly has lost most its specialists and machinery is mostly old. Needs massive recruiting and investment.
Is it privately owned or is the government neglecting it?
Saratov: Bankrupt
The government could buy it and upgrade it to make Il-276 prototypes... once it has made a half dozen prototypes it could make Il-476s while the Il-276 prototypes are being tested and evaluated and serialised. When the design is ready the Il-476s that have started production get completed and are replaced by serial Il-276s.
The advantage is that Il-476 production will be boosted for a bit and then the smaller lighter cheaper Il-276s can be put in operation taking some of the lighter shorter range work from the Il-476 so they can do work that require their capacity. The Il-276 will be cheaper to operate than the Il-476 for jobs that don't require the Il476s full capacity or range.
Aviakor is also producing some parts for SSJ-100 and MS-21.
Government contracts don't pay well but making parts for commercial airliners should be profitable.
