Designers have proposed replacing the An-2 single-engine monoplane

Ural Civil Plant aviation (UZGA), in the framework of the program to create a new aircraft to replace the An-2, came up with a proposal to create a single-engine monoplane for 9 passengers. This was announced by the chief designer of the aircraft factory Vadim Demin.

According to Demin, the new aircraft, being developed to replace the An-2, should be a monoplane with a high strut wing. Such a scheme, according to the chief designer, compared with a biplane, is easier to manufacture, maintain and repair, and also has a higher aerodynamic quality and, accordingly, better cruising characteristics.

Thanks to this design of the airframe, the aircraft will have a maximum take-off mass of 4800 kg, which is 1,5 times less than that of TVS-2DTS (7400 kg). This complies with the standards that set weight limits for light single-engine aircraft.

- Demin said on the sidelines of the MAX-2019, adding that the UZGA will come up with a proposal to create a single-engine monoplane with a capacity of 9 passengers to replace the An-2.

Earlier, the Ministry of Industry and Trade announced that a new aircraft with a capacity of 2 - 9 passengers will be developed to replace the legendary An-14. The single-engine TVS-2021DTS "Baikal" aircraft, previously planned for serial production from 2, developed by the Siberian Research Institute of Aviation on the basis of the An-2, will not be produced, but developments on it will be used to create a new aircraft.

The aviation industry explained that the decision on the fate of the Baikal aircraft, as well as what technological features will be used to create the new aircraft, will be made in September. Work on the creation of a new light multi-purpose aircraft to replace the An-2 will begin this year, the first prototype of the aircraft for static tests should be ready by December next year.

Because they think with it at the top and immediately manage to crap. A biplane is ideal for small aircraft. Low takeoff and landing speeds, low mileage, the ability to use "green" takeoff fields, fewer casualties in possible accidents, higher planning capabilities.

[tihonmarine]

Quote: Mavrikiy

A biplane is ideal for small aircraft.

Here is a simple and short answer.

[D16]

And the missing lifting force of the removed wing will be compensated by the gravitap.

Wing span, wing profile, lower take-off weight. The engine, the campaign will be VK-800. At 4,8t, that's enough.

[NEOZ]

the campaign will be VK-800.

Yes, I also think that they will come from the presence of an engine.

[bar]

And who needs such a buzz as a regional plane?

[abc_alex]

Antonov tried a monoplane. The network has a photo of the An-2 monoplane. The wingspan is titanic. After all, it was required that the plane could plan with the engine turned off.

[Baloo]

Quote: Gnefredov

Oh yeah. And the missing lifting force of the removed wing will be compensated by the gravitap.

In the distant school Soviet childhood, I saw the following picture: An-2 on the brakes gassed until the tail lifted, removed the brakes and after 50-70 meters was already in the air.

[tihonmarine]

Quote: Balu

An-2 braked on the brakes until the tail lifted, removed the brakes and through 50-70 meters was already in the air.

Khimdym always took off like that.

[novel66]

oh well ... just wider scope, SAH is thicker

[Undecim]

And the missing lifting force of the removed wing will be compensated by the gravity
You can immediately see that you are strong in aerodynamics.
An-2 flies beautifully and in a monoplane variant.

TR-301 version developed by Tehregion Production and Design Company LLC (Yeisk).
The engine is the native ASH-62, but with an fuel injection system and water injection.
Removing the lower wing allowed to reduce weight by 450 kg. The aerodynamic drag has become less, the wing load has increased. Cruising speed - 210 km / h.

[donavi49]

So the question is not whether it can fly or not. The question is landing characteristics and minimum steady speed. At Biplan they are the best. The monoplane has a large minimum speed (physics) and large requirements for the strip (again physics).

FAs were designed to at least maintain the characteristics of the AN-2, and ideally surpass. Including minimum speed, as well as landing requirements.

Cessna 208 is the closest to the LAN in terms of sound characteristics, is quite demanding on the band and has a significantly higher minimum allowable speed.

[Undecim]

If you have already decided to enlighten the audience in theoretical terms, then the terminology should be strictly scientific.
There is no "minimum stable speed" in aerodynamics. There is a minimum or minimum permissible speed of the aircraft - the lowest value of the steady-state horizontal (or almost horizontal) flight speed Vmin, permissible in operation.

[Gnefredov]

And on nitpicking to terminology from Undecim, never mind.

[Piramidon]

It is necessary to compare not abstract biplane and monoplane, but take into account, for example, such a factor as the profile and mechanization of the wing on a particular aircraft.

[dauria]

Question in landing characteristics

and this is solved by mechanization. Three-piece flaps and hover ailerons. By the way, Antonov himself followed this path in the An-14 "Bee".
And there is a worldwide successful experience - the hard worker Canadian de-heviland DHC-6.
It flies around the world, in Russia it is also used by a couple of companies. It was built from 65 to 88, production was resumed in 2012 and is riveted to this day.

and here is Antonovskaya "Bee"

[Elturisto]

It’s not with a holy spirit that you have blown away from modern trends. The priests will be sprinkled with a broom and the lifting force will be fixed and the braces will ring.

[NEXUS]

I’m thinking why there is no work being done to create a steam engine for airplanes, cars, etc.? Someone will say that steam engines are an anachronism, but ... the efficiency of steam engines is higher than that of ICEs, they are economical and do not litter the environment. Here is one of the projects still created in the USSR ...

At the end of the 50 of the last century, the Soviet Union conducted secret developments of an ultra-economical multi-purpose aircraft. The designers were faced with the task of making an airplane that could fly on any fuel, refueling in any conditions, with a flight range of at least 10 000 kilometers and the possibility of landing on very short stripes, as well as on water and swamps.

The first condition - omnivorousness, while respecting the principle of ideological intelligibility - and dictated to the brilliant Soviet designers the idea of ​​using a steam generator power plant. The glider of the ultramodern (the best in the world!) At that time Il-18 aircraft was taken as the basis for the future password.

As a power plant was used developed at the Institute of Gasdynamics. Stechkina is a steam turbine unit with direct-flow steam heating, unique in its technical and ideological characteristics. Steam heated in steam heaters, accelerating in nozzles-nozzles of an expansion-vestibular apparatus, rotated a steam turbine, from the shaft of which the alternating-constant 4-x phase current generator (in the number of generators) was driven. The propellers of the aircraft were driven by four electric motors powered by a generator, which during operation were excited and simultaneously cooled (the so-called principle of double vapor-electric expansion) by the exhaust steam of a gas turbine plant.

The first flight of the Il-18P with the steam afterburner on.

Modification of IL-18P with two bins for peat and one coal tender equipped with an automatic feed and fuel centering system AKCHG-CP, which significantly reduced the number of replaceable stokers.

When creating the aircraft, many unique technical solutions were applied, many of which were decades ahead of their century. Many of these solutions directly flowed from revolutionary steam turbine technology.

So, for example, the afterburner system was developed, when during take-off and landing the steam exited the boiler through a special nozzle and created a powerful jet thrust. This allowed to reduce the take-off run from 1000 to 120 meters, and the run-off length from 800 to 60 meters.

The system was further refined, additional maneuverable nozzles were added, with the help of which the aircraft could instantly turn in the air at almost a right angle to the course.

The efficiency of external combustion engines is really very good, only the electric motor is better. In a steam engine, it is almost one and a half times higher than that of an internal combustion engine (more than 30%). The Stirling engine is even more efficient. But the latter has one subtlety of a purely technical plan. In order not to eject anything outside during operation (to work without exhaust), the working fluid during the working cycle must not only be effectively heated, but also have no less effective cooling after that. It is quite problematic to provide a sufficient level of cooling on land "tarataikas", but on waterfowl and especially flying ones, one could even try to portray something. In any case, it would be interesting to try it.) And oil as a fuel will be useful to us in this case, in any case, steam locomotives have been working on it for a long time.)

at the beginning of the 80's, steam turbine engine enthusiast Jim Crank did not decide to break the “steam” 1906 speed record of the year. He himself could not build a racing steam car, but managed to interest Bob Barber, co-owner of the Barber-Nichols company producing steam turbine units. As a result, the ferryboat was still built, and in August 1985 of the year on the Bonneville plateau, he overcame the test mile at a speed of 234,3 km / h.

In the late nineties, I was lucky enough to visit KB Mil for excursions from the bug. Among the many domestic exhibits there was one Mi - 8 with a gas engine. To present this option to us, a man came out who was engaged in the development of a gas engine. It would seem like it (reliability, simplicity, profitability), but it didn’t go beyond a few flights. In order to use gas engines in parallel with traditional engines, not small cash costs are required. If we take into account that traditionally everything new is being introduced with a big fight, then a lot of things never reach the exit. Then, unexpectedly, it pops up abroad. And we shrug our hands in frustration.

I have a version ... at the beginning of the 20 century, companies such as Fort bought electric trams through front companies and destroyed the cars themselves. Also, a tax was imposed on the dimensions of vehicles, in connection with which, steam engines, AT THIS TIME , could not compete with cars with internal combustion engines. That is, I want to say that there was a systematic destruction of entire branches of production, because of which, at the beginning of the 20 century, electric cars and steam-powered vehicles did not develop in parallel with cars with internal combustion engines. Why is flawed production competition? Indeed, the efficiency of both the electric motor and the steam is much higher than that of the internal combustion engine, while the environment does not suffer, there is no noise, no hydrocarbons in such wild quantities are needed. That is, there was a systematic and most important INTENTIONAL destruction of competitors.

I’m thinking, why isn’t work being done to create a steam engine for airplanes, cars, etc.?
Because they have already been carried out. In the last century. There were a lot of projects, both with a steam engine and a steam turbine, including in the USSR.
Out of all this diversity on a steam engine, one aircraft took off - the Airspeed 2000.

On April 2, 1933, American inventors brothers George and William Bessler, together with engineer Nathan Price, demonstrated a plane called the Airspeed 2000 - a redesigned classic model of the Travel Air 2000 biplane.
The two-cylinder V-shaped steam engine "gave out" 150 hp. Ten gallons of water were enough for about 600 km of flight.

[Undecim]

In 1934, MAI students designed a star-shaped steam engine for the U-2 aircraft.

Moreover, in 1936 this engine was built. But they could not build a steam generator of acceptable mass.

[Undecim]

You see, here it is necessary to separate the social and technical aspects of your question.
If we consider the technical issue, then a steam engine, even in the form of a modern steam turbine, is unsuitable for installation on an aircraft due to the fact that mankind is not yet able to create installations for generating a pair of acceptable weight and size characteristics. Well, mankind has come up with nothing but a steam boiler and a steam generator !!! But they are not suitable for an airplane.
As for the social aspect, that is, the rams ... This is a difficult question. Indeed, a significant part of society is (sorry) a herd of sheep, which the shepherds drive in the right direction. It can be clearly seen even on the website, especially in the "News" section. Even such an interesting phenomenon is observed. Some individuals who demonstrate certain skills of independent thinking in articles on technical issues, getting into the "News" or "Opinions" section, turn into the very ones you spoke about, which are in the herd.
Perhaps among the site authors there is a specialist who will write an article explaining this phenomenon.

Only on December 19, 2018 in Aramil solemnly opened a new assembly shop for the licensed assembly of Czech L-410.

The constructed workshop belongs to the Ural Civil Aviation Plant (UZGA), which is part of the Rostec state corporation. The assembly shop at the Uktus production site was built in two stages. It is planned to reach full design capacity (up to 20 aircraft per year) in 2019. According to the statement of the Ural State Aviation Administration General Director Vadim Badehi, now “the level of production localization during assembly of a Czech-made L-410 aircraft reaches about 35%. By 2021, the level of localization should reach 72%. ”

[yehat]

According to Demin, the new aircraft, being developed to replace the An-2, should be a monoplane with a high strut wing. Such a scheme, according to the chief designer, compared with a biplane, is easier to manufacture, maintain and repair, and also has a higher aerodynamic quality and, accordingly, better cruising characteristics.

roughly speaking, they want to make a big cessna-2 instead of an-172.
in fact, Demin’s statement is quite controversial.

easier to manufacture

Well here hardly. Yes, there are fewer parts, but is it easier?

maintenance and repair

I think the difference is very small.

has greater aerodynamic quality and, consequently, better cruising characteristics

another question - how important are cruising characteristics
and how they differ in 2 versions. There are many other requirements for small aircraft - controllability,
obedience, low landing speed, strength and unpretentiousness to airfields, etc.
as far as I know, the strut monoplane is not so strong.
hang something on wings problem

in general, Demin’s statement is, at a minimum, highly controversial.
but in general, I would suggest a designer with different versions of the wings and layout

sawing very successfully in the USSR began around the 70s
began to open a bunch of projects, the completion of which no one planned, but the movement and supply and bonuses and positions. This flourished especially in the "republics." In the 80s, part of this phenomenon was called protracted construction. Now the "vertical of power" has returned to this mass practice again. A bunch of projects for the sake of movement and cash flows with zero utility at the end.
I can immediately call 5 such projects in St. Petersburg medicine (like a hotline for those at risk of getting a stroke, cancer centers that don’t treat it, but just try to cut it out in the last stages and many others). And just everyone knows about Chubais’s nano-results.

But what about medical projects, one project of turning the northern rivers to the south was worth what. Money buried in the ground.

And that was neither yours nor ours ... or maybe so ... both yours and ours! Let there be a monoplane parasol instead of a biplane!

[Kaw]

In the world, one of the most popular aircraft of this class is the Pilatus PS-12, launched in 1989
Features:
Maximum cruising speed: 528 km / h
Flight range 1 pilot + 10 passengers: 2 371 km

To compare the characteristics of the An-2 (in brackets for TVS-2DTS “Baikal”):
Cruising speed: 180 km / h (280 km / h)
Practical range: 990 km (1200 km)
At the same time, the TVS-2DTS “Baikal” has an American engine and other foreign components.

[Kaw]

In my opinion, it is he who should be taken as a role model, only trying to make his own as much as possible.

[yehat]

Pilatus is a good car, but it has 1 maaaaaalenky flaw.
it is about 20 times more expensive than the an-2.

[marshes]

There were airplanes like Gzhel M-101 T, you don’t need to invent anything new, just raise the technical documentation.

[AU Ivanov.]

The PC-12 has a lift-off speed of 160km / h. Landing around it. Annushka has a 75-85 lead. Pilatus will not sit on an unprepared site.

[Maxwrx]

There is a video in YouTube (I can’t find it now) where it lands on a poorly prepared site and takes off from it. I thought it wasn’t really possible to sit there. So I think not everything is so bad

[Maxwrx]

But only it costs about $ 7 million, and Baikal 130 million rubles ($ 2 million). This is how to compare Vesta with Porsche

[yehat]

in general, a lot of our current problems are connected with a somewhat strange policy of industrial development in the USSR.
I just don’t understand why a lot of production was carried out to Poland and other outskirts of the country. Was the summer of 1941 taught nothing? Why didn’t the actively combined centers of the entire production chain, for example, an engine-building plant and an aircraft, be within an hour's drive by car?
A plant was working in my city, the materials for which were produced for 2.5 thousand km. This is normal???
We are now reaping the benefits of this shortsighted strategy.
Why is Ukraine so kicking? Yes, because it was necessary to place in Kiev not heavy industry, but light and food processing, as well as various kinds of research institutes, but with a very limited industrial base.
and in the RSFSR it was not necessary to build Togliatti, but industrial centers as in Japan, when all the supply and assembly enterprises are located in a 150 km circle. And somehow they have no problems with suppliers, subcontractors, staff. Just as there are no problems with the Americans making films in Hollywood.
Back in school, when I studied economic geography, I was greatly surprised at the inefficiency of the location of industry.

[Ratmir_Ryazan]

If all production is concentrated only in the center, then where do people work on the outskirts and in the province?

The land will empty out without people, strangers will come and take everything away.

Japan, your beloved, is slightly larger than Sakhalin, and 130 million people live there, almost like in Russia in ALL.

Only 5% of the population of Japan lives in Hokkaido. Well, the Japanese do not like the cold, because there is no stove in their paper-rack houses.

Japan is your favorite a little larger than Sakhalin

Due to the distortion of the cartographic projections (from round to flat), the closer to the poles the larger the object appears.
Japan is 5 times larger than Sakhalin; it is larger than Norway. Sakhalin - 76 sq. Km, Norway - 400 sq. Km, Japan - 324 sq. Km.

According to Demin, the new aircraft, being developed to replace the An-2, should be a monoplane with a high strut wing.
In this regard, the chief designer Demin did not make a special discovery.

An-14 "Pchelka" (NATO had a formidable name Clod - "Glyba") - a Soviet light transport aircraft intended to replace the An-2, made its first flight on March 14, 1958. The aircraft had a short takeoff and landing capability and was designed to operate from unprepared unpaved sites.

[Undecim]

Decades have passed, but the concept has not changed, just "Pchelki" have reached the modern level.

"EV-55 Outback" - Czech light multipurpose aircraft for short takeoff and landing.

twin-engine aircraft have 3 minuses -

2. more expensive maintenance
3. The essence of this scheme is the ability to pull on one engine, but skilled pilots,

[Undecim]

power and excess consumption are not always in demand
Complete nonsense. You can choose any power. The same EV-55 Outback has two Pratt & Whitney PT6A-21 turboprops with 540 hp each. An-2 has one piston ASh-62 with 1000 hp.
more expensive maintenance
Any specific numbers?
At your glider, according to your concept, maintenance is even cheaper. True, no one builds passenger gliders. Passengers regret.
the essence of this scheme is the ability to pull on one engine, but skilled pilots,
who do not cope well with this by far. And for small aircraft, simplicity and affordability are important.
Any statistics?
The essence of this scheme is the ability to continue flying on one engine to the nearest landing site. Nowhere is easier. If the pilot does not know how, he has nothing to do in passenger traffic.
And besides simplicity and accessibility, safety must be respected.

And the missing lifting force of the removed wing will be compensated by the gravity
You can immediately see that you are strong in aerodynamics.
An-2 flies beautifully and in a monoplane variant.
.........

Removing the lower wing allowed to reduce weight by 450 kg. The aerodynamic drag has become less, the wing load has increased. Cruising speed - 210 km / h.

May I continue for you? (but they didn’t finish it, somehow awkwardly it turns out):
- Deterioration of water shortage (higher take-off and landing speeds);
- The large area of ​​the wing of the biplane has a large lifting force, which requires a less powerful engine, and this is the economy of fuel and lubricants (although there are endless debates on this subject);
- The geometric dimensions of the glider along the diagonals. If you want to get the same VPH on a monoplane, it will be larger, at least in terms of wingspan.
--
In general, what are we arguing about? AN-2 has its own niche. Would you like to borrow? Yes please. Just imagine a normal airplane (and not a single sample!) Not inferior in performance characteristics to the AN-2. I’m boiling for anything other than a strike ... And then they attacked the brainchild of Oleg Konstantinovich, the hereditary Siberian who created this model seventy years ago, but there is nothing to offer in return.

Please change the engine, lighten the airframe design, and finally launch the replacement of the AN-2 into mass production, I’m only for it. In the meantime, there is nothing, behave decently, but what am I talking about, I am not good at aerodynamics, I am in electronics, on which you fly on "iron birds" (and in AN-2 it is not at all).

That there is supposedly the development of alternative ICE engines with high efficiency, but the oilmen do not give it a go

Physics does not, not people. Gasoline-kerosene gives a power of up to 2 kW per cm² of piston, while the steam resistance and stirling also interfere with the thermal resistance of the boiler pipes, hydraulic resistance of the liquid and turbulence in the steam lines. The best steam locomotives with triple expansion steam engines have barely 0,5 kW per cm², the cylinder has 1500 hp. has a diameter greater than a meter.
There is, however, an example of a valid password - Me-162. But there - the working fluid and fuel are combined, a solution of hydrazine in water was mixed with a solution of potassium permanganate in water, pshsh! - and - two minutes to an altitude of 8 thousand meters.

If all production is concentrated only in the center, then where do people work on the outskirts and in the province?

not all production is in the center. The only question is redistribution.
for example, in Latvia, the production of crystal, towels, sprats, door locks, east of the Leningrad region - the RAF plant and a radio factory, preferably not far from St. Petersburg, where there are a lot of suppliers and research institutes.
and we did the opposite - we sprayed narrow complex competencies on the outskirts, because of which any problems led to the destruction of industries and logistics was enchanting.
In this case, politics strongly influenced the sober and logical disposition of industry.
Further, the development of industry of the republics could not be done without mutual conditions.
If an enterprise is created, on which the entire union is thrown off, it does not become the property of an "independent" or "proud mountainous country", but remains the property of the union with the corresponding obligations. But further, it is already possible to redeem powers by barter.
A simple example is the Kharkov Tank Plant. This is a 100% company created by the RSFSR, but it suddenly became primordially Ukrainian. even worse example - Sevastopol and Crimea in general.
or another example is a lithium plant in Kazakhstan. Yes, they would not be able to build this without the RSFSR and maintain at least another 500 years. And as soon as the USSR was divided, the enormous possibilities of mutual supplies and diversification immediately became cut off for the industry of the RSFSR.
The issue is not in the export of production to the "center", but in normal communications, the location of production so that the economy does not interfere with logistics and centrifugal events in the outskirts. Well, the republic separated with the production of brooms or ice cream - well, okay. And if there is the only bearing plant in the union?

The large area of ​​the biplane wing has a large lifting force, which requires a less powerful engine, and this is a fuel and lubricant saving

here is a slightly different question. the biplane no matter how you twist more drag, but better lift
if you try to squeeze the maximum speed, the flow will be better with a monoplane.
the option with 1 wing may be better for transporting not heavy passengers from concrete blocks, and for villages where they can carry a lot of cargo, where unpaved short airfields - a biplane is more justified.
But the distances are not so large - I think the decrease in speed can be neglected for other advantages.
For example, I go to my parents 270 km from St. Petersburg on a clogged Murmansk highway. Due to traffic jams and other garbage, such a trip to the 1 end can easily be 5-8 hours, 1 times traveled 11.
And on the An-2 you can get there STABLE for an hour and a half. And the price is quite reasonable -
on a regular car it’s about 45 liters of AI-95, for an-2 the consumption for such a flight is 200 liters
and he carries 12 people. (usually 4 in a car). If you divide 200 liters by 3, you get about 63 liters versus 45 on a car. At the same time, instead of at least 5 + 5 hours on the road (-1 day out of the usual 2 days off), it turns out only 3 and it is really possible to drive normally on weekends with decent comfort. So why are there no such local shipments practically anywhere ???

[Karabas]

And this Vadim Demin was interested in the opinion of the consumer? And at the very thinker did not itch, why do people need a biplane? I suspect once again the cerebellum of the effective manager has worked - First we slap, then we rape, but they will not take it - turn off the gas.

[Alexander Sosnitsky]

A biplane will always be more reliable and lighter due to light stretch marks. Greedy wolves attacked the old man, who could live and save many lives with mass use, where speed is not particularly needed. This is just another class of aircraft. And who cares about their lives, nobody.

[Alex66]

It seems that the new An-2 could not be launched into a series of reasons, it can be different from corruption to technical, or maybe there are no assemblers, vocational schools are closed. If this couldn’t be said about the MS-21, it will repeat the fate of the superjet. It’s a pity there is no person in charge of aviation, only managers, such as Mutko.

I confess dabbled in calculations of profitability of the organization of flights of small aircraft
and I’ll say that the An-2 is redundant - even it is too big.
but on the other hand, here's a simple example
Now the Yak-40 freight (40 seats) on the flight MSK-SPB-MSK costs 480 thousand rubles. (this is not very profitable)
the average minimum ticket price is about 6-7 tr.
And the Yak-40 is quite expensive to operate, the An-2 is very much cheaper.
Peregrine Falcon costs the cheapest about the same, and half the tickets are sold from 17t.r. and goes 3 times longer.

A number of small private twin-engine airplanes generally have a problem - they lack the size of control planes or there are no control lever amplifiers to reliably compensate for displacement.
