Twin-engine monoplane: what will be the replacement for the legendary "Corn"


Russia, with its gigantic distances, needs its own light multipurpose aircraft, reliable and unpretentious, to supply remote regions. Previously, the Soviet An-2 did an excellent job with this task, but the legendary "Corn" has not been produced for a long time and objectively needs to be replaced.


Now cargoes are delivered to the Far North by large transporters, and after that they are loaded onto helicopters that are capable of landing on unequipped sites. The use of multipurpose light aircraft can make logistics more cost effective. Our "Annushka" is capable of carrying small loads and passengers, landing on unprepared runways. Due to their unique reliability, biplanes are still in operation in a number of regions, despite their venerable age. Some have been in service for over 40 years, but this cannot go on indefinitely. The country needs a new light multi-functional aircraft, and several projects have claimed the role of successor to the An-2.

TVS-2DTS


Initially, the SibNIA project under the designation TVS-2DTS was considered as a replacement for Kukuruznik. This is a traditional biplane that the developers were able to make an all-weather aircraft, thanks to a new fuselage, avionics and a one-piece carbon fiber composite structure. Its payload is 2450 kg, flight range - 4500 km, cruising speed - 350 km / h. The indicators are very decent, and with a cost of 150 million rubles, it was possible to organize the production of light aircraft with a volume of 2021-25 units per year at small enterprises already from 30.

Despite this, the Ministry of Industry and Trade refused the project. The reason was the sanction risks that the MS-21 and Superjet airliners have already faced. On TVS-2DTS, foreign-made composite materials and the Honeywell TPE331-12UAN power plant were widely used. A light aircraft at any time could be left without key components and assemblies. In addition to this, experts pointed out potential problems with the composite wing, which could arise during operation, repair and storage in the harsh northern conditions.

TP-301


This is another interesting project from the Technoregion company. Structurally, it is a modernized "Corn" without lower wings. Its payload is 1500 kg, and its weight is reduced by almost a ton compared to the prototype. Using the Czech engine Walter M-601 with a capacity of 700 hp. from. allowed to reduce fuel consumption by 40%.


Several units have already been produced, the developers claim that during commercial operation, their aircraft will pay off in just 6-8 years. However, the key problem of the project was also dependence on the use of a foreign power plant.

"Baikal"


As a result, officials of the Ministry of Industry and Trade made a choice in favor of the development of a subsidiary of the Ural Civil Aviation Plant (UZGA). Baikal-Engineering LLC won a tender a year ago, and its light aircraft design has undergone significant changes in comparison with the An-2. First of all, the biplane will turn into a monoplane, and its capacity should increase to 12-14 passengers. But most importantly, the aircraft will be equipped with a domestic-made engine, and, apparently, there will be not one, but two at once. UZGA is working on its own power plant together with UEC-Klimov.

Apparently, the Ministry of Industry and Trade is waiting for a budget analogue of the Canadian DHC-6 Twin Otter. It is estimated that the demand for "Baikals" in the next five years can be at least 230 units in our country. The project is tentatively estimated at 4,5 billion rubles. Let's hope that the plane will live up to its expectations.

    This is how it was, under the communists, corn workers did it themselves, from their parts. 20 years have passed Putin's power and such a big problem has formed. A corn engine is that a spaceship engine? This is the same we must purposefully work in this direction!

    ....... Apart from the crash everywhere,
    zero production,
    but I kept on repeating
    Putin raised everything in the country! ......

      Yes, this is very problematic. The question is not so much a design one as a financial one. In principle, an engine for a light aircraft does not fundamentally differ from an automobile engine (if we are talking about a piston engine) and the development costs are more or less similar. But in the case of automobile costs, the costs are divided by the millions of cars produced, in the case of airplanes - by a hundred or two. And in Russian realities - in general, the production will be piecemeal, and will never pay off.
      If you do everything wisely, you need to buy a license for some Lycoming. And to release it with us until all the factories are killed. Thus, the logistics of supplying spare parts, service and repairs will be greatly facilitated if parts from original American engines are suitable. This is with regard to the piston. As for the gas turbine - there seems to be an 800-horsepower on the way. If they do not "shift to the right", then there is every chance. Although one must be prepared for the fact that this motor will be very expensive, due to its small series.

      Ps By the way, almost all corn makers were made in Poland. We gave them this hack within the CMEA framework.

      Hmm ... everything is just SOVIET - COULD! and did. And then they showed the result!
      The current "at the feeding trough of VLASTI" in Russia is simply NOT ABLE .. to create ONLY sell, AND STEAL.
      Hmm ... the incapable are just impotent.

      If you don't know, then An-2 was riveted in Poland and Russia has NO RIGHT to release it. Putin is to blame for everything, even that the bare-assed commies sold the license to produce An-2 to the Poles and China.

    The Soviet An-2 did an excellent job with this task before.

    1. Then the gasoline on which the An-2 flew cost a penny and maintainability at the level of rural machine operators. Today the same An-2 TVS-2MS SibNII im. S.A. Chaplygin, who largely retained the continuity and outlines of the legend, and therefore the minimum costs of preparing for mass production in comparison with the newly created ones, is unnecessarily crammed with various modern moorings. To increase the cost or something, they will buy and operate with budget funds.
    TVS-2DTS, which is Baikal, has good characteristics, but they mocked the legendary An-2 from the heart by creating this freak, they were not allowed into the series.
    2. Rural airfields today have turned into pastures for livestock, overgrown with young forest growth or built up with cottage settlements. To bring it into a serviceable state, a lot of budget money is also needed, and rural settlements often do not even have money for street lighting and road repair.
    3. I suppose the emphasis is on light vehicles, preferably helicopter type, gyroplanes and mini helicopters, with a capacity of 3-5 people and 100 kg of cargo, simple and reliable like Po-2 and available to average citizens.

    Cargo can also be delivered by unmanned drones. Anywhere.
    Maybe then the plane is not needed at all and the landing site?

    It won't take off without an imported engine and avionics. There is no market for small aircraft in Russia.

    The Russian Federation produced quite a decent An-3. There is nothing to reinvent the wheel, it is also quite decent, for its purpose, you just need to return it to production

      They did not release the An-3, but alter it from the An-2. This is called remotorization. We do not have the rights to release the An-2 and have never produced it in Russia for a long time.

    Interestingly, does the army need an aircraft of this class? Small transporter, ambulance, for the landing of small troops, etc.
    If you turn on the brains? In order not to fly aircrafts of the AN 26 level? The Second World War began and immediately the army needed 2 in large quantities. And what did you think about before the war? And the aircraft was produced with linen covering since 1927. until 1953
    Then the plane would quickly appear and the civilian version would immediately cost moderate money. And there would be export potential.

      Why is he needed in the army? Do you want so much?
