Rostec presented a plane for local airlines in Yakutsk

The Russian Helicopters Association (part of Rostec) and the Siberian Research Institute aviation (SibNIA) held in Yakutsk a presentation of the aircraft for regional aviation TVS-2DTS, said press office corporations.

It is reported that the serial production of the aircraft will begin in 2021 at the Ulan-Ude Aviation Plant (U-UAZ), and the Yakut airline Polar Airlines will become the first operator.

The project is being implemented as part of the state program for the development of regional air traffic in remote areas. We expect that the commissioning of the new aircraft will allow connecting the most inaccessible settlements of Yakutia and Buryatia by air routes. TVS-2DTS is perfectly suited for this purpose, since it has a high maneuverability and is designed to operate in the most severe climatic conditions,

said a representative of the aviation cluster Rostec.

During the presentation, several pilot flights took place with the participation of full-time pilots of a local airline.

The press service recalled that “TVS-2DTS is a light-engine aircraft designed by SibNIA. S.A. Chaplygin, which is planned to be used to solve the problem of low transport accessibility of remote populated areas of Russian regions, to solve state tasks of providing emergency medical care to the population, extinguishing forest fires, and carrying out agricultural work. ”

One of the requirements for a new aircraft is the possibility of landing on unpaved runways, as well as water and ice.

Before 2025, the Ulan-Ude plant plans to supply up to 200 such machines for the needs of regional aviation.

And most importantly, the Yankees engines on the plane. TVS-2DTS is equipped with a Honeywell TPE331-12UAN turboprop engine. TPE331-12UAN is an excellent, universal, reliable, long-brought to mind, economical and omnivorous, proven on the tracks of Alaska ... One can only hope that Trump will be more busy with the trade war with China and will not stop deliveries.

Fortunately (or unfortunately) we need such machines, I think, we need much more 200 pieces. And they could be used not only on local routes, but also in agriculture, and in the army - but anywhere! If he can replace An-2. Who from those who in life jumped with a parachute, does not remember the first "Annushka"?
So one could think about his engine. And “abroad will help us” - so how many times have their foreheads been smashed about this? And we, and neighbors - near and far .... And if it comes to America, so what holiness and inviolability of the treaty can we talk about? Immediately drive your own!

Well, for example, the legendary ASH-62IR, which has been carrying An-70 and 2 for years - Lee-80 for 2 years, was "girlhood" by the United States "Wright Cyclone". AL-82, the Victory engine on La-5 / -7, grew out of AL-62. Here is M-105 with Yak-3, he was not American, this is the former "Spanish-syuza", a Frenchwoman. Like the SaM-146 on the su-jet.

It’s one thing to “blow off” the engine and make your own on the basis of someone else’s - and it’s completely different to depend on the supply of “probable friends” ....

The first production ANT-9s flew with the Wright and the Dwarf. Then they began to put the M-17, made of BMW, but the chances for several years we were supplied with some precision parts for the M-17. Everything that happens at some point in time has already happened to someone before ...

Good day, Alex! I read somewhere, but could not find it now - import substitution. the engine is already looking. Aircraft fuel assembly back in 10g. started to develop. And no one thought that there would be sanctions and Ukraine. Amer engine in 1100l.s. I think even with Mi-8 TV2-117 can be replaced (1500hp - maybe the range and speed will change a little). With Motor Sich in the Russian Federation there is a joint venture.
I need a plane and I think that will take place.

I am still inspired by the example of the Soviet Union. Yes, we also had some equipment at the plants imported. There were imported dump trucks, and Ikarus buses in bulk in cities. But also it was important - economic security. Whatever sanctions were imposed by anyone, with whom, with which Motorsichi relations did not deteriorate, the Soviet Union could exist autonomously. There was no fatal dependence on imports. And now we’ve come to the threat of food dependence on imports ... Shame ...

[Aaleks1974]

As I understand it, they will solve this problem until the 20th year, because the AN-2 glider itself has been remade for about 10 years already, so the engine remains to be completed. Although it was the same AN-3?

[Avis-bis]

Quote: Aaleks1974

the AN-2 glider is already 10 years old, as it was redone,

Less than five.
An-3 is, but there is nowhere to build it from scratch, and remotorization costs so much that there are almost no customers. And those that are, either state ones (EMERCOM) or money, are not particularly considered (all sorts of northerners, where there are no alternatives to aviation).

Secondly, it may be easier to do, but it’s more difficult and expensive to operate. At least five parameters.
Well, and vibration, of course ...

[groks]

At least D, at least U, and oil does not need the simplest motor oil - temperature, speed. This is the first parameter. That we in the case of a sheher will be chopped off not only by the military commissar, but also by civil aviation - the second parameter. It is impossible to maintain or even repair a turbine in those places where this aircraft is needed - the third parameter.
You can still dig, but is it worth it? And so it is clear that a large-scale drank. For this, they would have been shot in the middle of the last century, then they spit on the ban on producing the right fuel. And they would fly on their own, with their own.
However - what is it all about? Who did this plane surrender to? WG if only vpendyuryat.

[Avis-bis]

Quote: groks

At least D, at least U, but the oil does not need the simplest motor

And what? :) Butter is like butter. Well, of course, not a solid and not a castro ...
In TVD, the same oil is included in the oil mixture as is used in PD. For example, ASh-62 is lubricated with clean MS-22 or MK-22. The oil mixture for the AI-24 TVD consists of 25% of it. The remaining 75% is more liquid MS-8 or MK-8, and there are no fundamental differences.

temperature, revs

There is nothing transcendent either in revolutions or in temperature. Especially in temperature. I will say more: in a gas turbine engine, the oil operates at a more gentle temperature than in a diesel engine, because it does not come into contact with the red-hot inner surface of the cylinder and a burning internal combustion engine. If in a gas turbine engine the oil coming out of the bearings has a temperature usually not higher than 120-150 ° C, then the ASH-62, for example, has a normal cylinder head temperature of 180-200 ° C, imagine what’s going on inside.
Do not compare motor with aviation. Example: an AS-62 aviation PD (not the most powerful air-PD in history) has such an oil consumption that it is necessary to add oil after almost every long flight, the maximum is at the end of each flight day. ASh-62 burns 6 liters of oil per hour. On a rather high-torque turbofan engine NK-8 (IL-62, Tu-154) if the oil consumption is 1l / h, this is already considered a lot. The usual flow rate is 0,8 l / h. But where is the NK-8 (for the NK-8-2U modification, the thrust is 10,5 ts) and where is the ASh-62 (the thrust is only enough for the 5,5-ton An-2) ...

in the case of a sheher we’ll be chopped off not only the military commissar

The dialogue began with the development of a domestic gas turbine engine for light aircraft: Ka-226, An-2-class ... Will we cut ourselves?

neither service, nor even repair a turbine, in those places where this aircraft is needed, is impossible

Who told you that? I'm talking about "service." Repair does not work, it is "yes." Repair can be replaced by replacing the module. We have big problems with this, but they are solvable. The first modular engine was developed in our mid-1970s - this is the D-36. 8 modules, EMNIP. And now, non-modular, it seems, is not being developed at all.

You can still dig

Dig. Not convincing yet. GTE in the class "> 300-500hp" beats piston motors with a big head start. Which is proven, if you are not convinced by the facts from me, the example of the remotorized Porters, Beavers / Otters and many other less famous planes.

[groks]

The dialogue began with the fact that in a few years we may (!) Get an ugly American plane, which is no longer needed. But probably already now this material the St. Petersburg Jew-Satanist (s) drags on Sdunas and the crowd of idiots jumps - then overwork! (S)

If the first, then do not worry like this: the phrase “demonstrator technology” in the series will be removed for obvious reasons, “DTS-2” or something else will remain. ATR-72-500, at least, doesn’t scare? Or did he also "kill" someone?
Or An-24RV, also not the shortest name. Scary too? The Boeings also have three-digit designations for modifications, mixed letters and numbers, the devil will break his leg. Airbuses have three-digit numbers in the modification indices. And there is still such a terrible aircraft with an incredibly creepy designation Tu-204-100V. Who did he "kill"? Or IL-96-300, the kingdom to him ... And what do you think about the Mi-8MTV-1 helicopters, such people fly in the Ministry of Emergencies, wounded, it happens, they save ...

Put the hydrofins on the L-410, the stub will die at the first serious strain.

Rationality itself, not a drop of glamor. Those. in 1958 what was now created by the Russian Federation was not capable of. No matter how sad it sounds.

They reduced the weight of the wing by applying a composite. There are no braces, instead of them - a closed power circuit. The lower wing certainly works in flight as a strut wing on the "bellanks". It was high time to abandon the braces, for you would not provide them with an anti-icing system.

Interesting ... Everything else is just a fiction KB? Antonov invented it and he himself worked for them and received a salary?

[Captain Nemo]

They used the composite, the braces were removed - then why do we need a biplane circuit? The lifting force is almost the same for a biplane and a monoplane with the same plane span! In the 50s, it was clear, but now what are the victims of the exam?
----Is everything else KB just a fiction? ---
Look, so to speak, from inside the design bureau (worked at the Tupolev design bureau). For one engineer in KB there are a couple of students and several technicians. Technicians do not engage in creativity - template calculations, design drawings, and some even can’t really sharpen a pencil. Throughout the design bureau, a plane really comes up with a handful of specialists. In the western design bureaus, those who are at a dance are even bigger. Antonov incidentally wrote in his memoirs about this.

[Captain Nemo]

The lower planes on this unit as a strut do not work - the wrong geometry.

Previously, the carriage of passengers on single-engine aircraft was prohibited by ICAO rules. Russia is a member of ICAO. Something has changed ???

Firstly, ICAO does not prohibit anything in principle, but issues recommendations that member countries may adopt as law, or may not. Secondly, there are no prohibitions on passenger transportation. By the way, the USA and Canada are also ICAO members, and there the cessna-208B carries up to 13 passengers.
We also do not have a passenger ban, but there are restrictions. For example, according to the number of passengers - up to 9. In the USA and Canada this restriction is not so strict. For example, there are still restrictions on the terrain over which such an airplane can fly: sea, desert, mountains, and so on. For example, when flying above water, the coast should be at a distance of planning when the engine fails. Not only the Ts-208 fly around the world, but also the Porters, Otters, Pilatus-12 and so on.

The lifting force is almost the same for a biplane and a monoplane with the same plane span!

Funny.

[Captain Nemo]

If one more wing is added to the monoplane, the total aerodynamic quality (the ratio of Su to Cx) will decrease. Even without considering the mutual influence of the flow around, doubling the wing is equivalent to increasing the chord, and not the span.
For a biplane with a span of L = 6 m and a distance between wings of h = 1,3 m, we obtain the equivalent monoplane span of Le = 6,8 m, but not 12m.
Antonov perfectly understood such things, and therefore, to replace the An-2, the An-12 was first created, and then the An-28. Most graduates of aerospace universities of the Russian Federation do not know this. Here you need not laugh, but cry.)

That's when you learn not to confuse lift with quality, then be smart. It’s too early for you yet. And the quality is not cumulative.
Cry in the corner, you might grow wiser. And maybe learn the short word "interference" instead of the awkward scholarly "mutual influence."
And at Yakovlev's “Pacimuta” the addition of a wing on the Yak-12 reduced the take-off run to 35 meters. I forgot to ask "nemo", probably. And in SibNIA fools are sitting, they also did not ask “dumb”. At first they made a high-wing, but then returned to the biplane. Well, all fools, only "dumb" on a white horse. :) And how could they have done anything in this life without being “silently” ... But “silently”, I suppose, turned a masterpiece like Tu-334 with a file.

[Captain Nemo]

Why be rude, Sergey. I don’t know, with aerodynamics you have gaps, but it's not scary. Forgot to add Yak-12B still boosted to 300hp AI 14-RF engine and other improvements to reduce take-off distance. Somehow, this is not a completely honest comparison. You obviously were not engaged in the design of aircraft, maximum operation and this is clearly felt. Well, okay, you can still see the guy with his soul in the Aeroflot, let's be friends.))) I’m sure that the Siberian Research Institute has very smart specialists, but not everything is in their hands. Regarding the Tu-334, to which I had to attach a file: the Tu-334 was developed since 1992, and about 100 million dollars were required for everything about its creation. We were told: “shovels” design bureaus are good for nothing, they are costly, inflexible - and they carried other nonsense. In fact, $ 100 million is very modest. The Embraer and Bombardier firms spent 600 million each on the development of similar machines.

The ruling monkeys in the Russian Federation, dropping the Tu-334, decided to develop a new aircraft. The competition was won by the Sukhoi company, which promised to develop a super-duper-breakthrough machine-masterpiece without raising public funds. She was recognized as the winner. But then it turned out that the development would go at the expense of the state. According to one source, they spent 1,2 billion dollars on it, while on the other (if we take into account all state guarantees for loans) - 2 billion.

2 billion and 100 million - this is a difference of twenty times. It turned out like in a joke about new Russians:

- How much did you take a tie?
- For a thousand bucks!
-, around the corner they sell one and a half ...

As a result, a plane was born that, by no means, can be called a breakthrough one. It is 80% slap from finished parts of foreign production. That is, already - the car of yesterday. In fact, this is a “screwdriver assembly” machine, a national disgrace. An interesting detail: Boeing supplies doors for SSJ. For 2 million dollars. And on "Tupolev" a whole glider plane for 3 million do. The correct name for the superjet is Dornier 728.

A little about yourself. He also managed to “scratch the file” with the Tu-160, the gas version of the Tu-154, the “open sky”, the Tu-204 and more. And for the soul - trike, glider, light-engine flying.
Sergei, though she’s not always as sweet as a carrot, it’s often bitter.

[Forever so]

Wheels need to be wider for landing in the field. Forever we have AN2 on the field in the swamp elm, pulled out by tractor.

Yes, for God's sake ... I do not like the Yak-12B, here's your favorite "Bee". Podkosny high-wing. Quality 10,8. And what is the quality of the predecessor biplane? You won’t believe it - 10 (Ten). Well, everything is so bad for biplanes, everything is hopeless ...

I’m sure that Siberian Research Institute has very sensible specialists, but not everything is in their hands

Yes. Conspiracy.

Regarding the Tu-334, to which I had to attach a file

Hmm ... I hope, though, not to the chassis ...

"Dry", which promised to develop a super-duper-breakthrough machine-masterpiece

There were no such statements. It was about "modern." And she did it.

2 billion and 100 million - this is a difference of twenty times

... and at 15. "Inflation", there is such a word ... And "disaster." In the late 1980s, the entire ex-USSR was stolen for a penny.

It is 80% slap from finished parts of foreign production. That is, already - the car of yesterday. In fact, this is a “screwdriver assembly” machine, a national disgrace.

The "cry of Yaroslavna" began ... I won’t even spread the infographics on the cooperation of the same 787 or kc-390, I'm tired and tired already.
And if the su-jet is yesterday (well, let's say for a moment), then 334 is the day before yesterday. The layout, the composition of the EMU, the free tonnage. With a full short circuit of fuel, it is enough for either 600 km or 1000.

An interesting detail: Boeing supplies doors for SSJ. For 2 million dollars.

Ahhh? :))) 4x2mln.dollars at the catalog price of the entire aircraft at 35-40mln.dollars? Nude ...

The correct name for the superjet is Dornier 728.

"Crying-2", too, is already sore. Outward resemblance is a dumb argument.

gas version of the Tu-154

This is called the "Tu-155" and NK-88 there is only one, it was not a "gas" aircraft.
