Western media from Mi-28 transferred their admiration to the Arctic from TsAGI

“Western media admired Russia's amazing Arctic helicopter”

They just do not admire, but rather, they saw their own benefit in this, which may mean the initial futility of this project - the future Arctic from TsAGI is not a rival to them, which means that they should be glorified as they are long obsolete and unsuitable for modern war. combat Mi-28 from the cost center.

Let's try to figure it out:

"The Drive information portal told about the" amazing aerodynamic design "of the promising high-speed Arctic helicopter of Russia».

Jet engine helicopter

It is about developed by specialists of the Central Aerohydrodynamic Institute named after Professor N.Ye. Zhukovsky concept of promising high-speed helicopter. The project is being developed as part of the Arctic development program announced by Defense Minister Sergei Shoigu. This program is designed not only to study the richest deposits and maintain the required level of combat readiness of the Russian forces in the region, but also to create socio-economic guarantees for the population, modernize the system of emergency medical care and equip it with new-generation aviation equipment.

Such a concept, as The Drive experts note, assumes that the helicopter will have an incredibly high speed, and at the same time it will be able to travel over distances over 1000 kilometers. According to the publication, such a device can be extremely useful for Russian troops in the Arctic. ("Political Russia").

Yes, it is said loudly and the look of the design is unusual, as if polished. But still, this project doesn’t smell like a new concept: just replacing the tail rotor with a jet engine, to which the mathematics says: “From changing places of the terms, the amount does not change!”

Besides, has there already been something similar on the Internet? Oh yes: "Eurocopter x4",

only at the end of the tail boom instead of a jet engine from TsAGI, the Eurocopter has a fenestron, and the rest: the twins are brothers! But there was no need to read admiration from the Western media on X4, this concept was adopted by them every day, according to our saying: “They count chickens until the autumn”.

And the liberal media are anticipating: the West is already delighted - this will be technology! Rejoice in advance !!! Relying on simple-minded Ivan, because a single-rotor helicopter (with a jet engine or with a fenestron in the back) has an aerodynamic limiter that will not let him into the high-speed range for any corruption. The bottom line is that with an increase in flight speed, the difference in the magnitude of the thrust (lift forces) of the left and right halves of the air carrying from the oncoming flow also increases, which means that the roll will increase in one direction or another (for Mi helicopters, to the right ). And already with V = 400k / h. the oncoming flow on one side and the passing one at the same speed on the other side will so overwhelm the helicopter (green arrows in the figure) that there will not be enough control to neutralize it. The end will be sad and then the tail jet engine and the cunning tips of the rotor blades from NS will not help. Pavlenko, about which I have already written more than once.

The classic helicopter was invented at the beginning of the last century, more precisely “In 1910 — 1911. Boris Nikolaevich Yuriev, academician, winner of the Stalin Prize, proposed a single-rotor scheme of a helicopter with a tail rotor and built a helicopter over it. For that time, it was an advanced helicopter scheme, which has so far irretrievably lost its former significance, since any other scheme (coaxial, transverse, longitudinal) is faster, more economical and much safer.

In this figure, the disassembled Mi-8 can be seen separately tail boom (№13) - the carrier of the future tail jet engine (RD), which, by the weight of its weight, will also reduce the helicopter payload.

Responsibilities for her share fell heavy: to withstand the load on the fracture from XB. screws (RD) with a capacity of more than 500l.s. As for the jet tail engine directly from TsAGI, it will itself get into an expensive penny, and secondly, it will need additional fuel and also for the payload. Hence the question: is it worth the “game?” Yes, and even this engine must be searched? We must assume that this drawing of “high-speed arctic from TsAGI” is an order from the general designer of the holding “Helicopters of Russia” N.S. Pavlenko to receive another billionth portion of finance for the “future high-speed” helicopter, but under the pretext: “for the Arctic”. And colder means more!

No, I doubt that the future design of such a helicopter is intended precisely for the designation center of the Moscow Helicopter Plant. M.L. Mile, and they, poor fellows, still don’t bring their usual Mi-38 to their mind: “About 38 billion rubles was directed to the development of the Mi-2-2 helicopter. The Ministry of Industry and Trade of the Russian Federation announced a tender to select a contractor to complete the creation of a helicopter ”(AviaRu).

And this dyuzhe capable in long-term design bureau, and only the Putin-Medvedev government does not deny confidence in the design of future high-speed helicopters: transport and combat! It’s very sad that the future of our helicopter building is handed over to the CBM through the holding “Helicopters of Russia” holding, knowing in advance that the billions of dollars allocated to them will be regularly spent on a zero result! Moreover, if they build their own Mi-38 already under 40, then high-speed RD (and suddenly they will be entrusted with it) they will build 50 commercials for years - just manage to allocate finances! By that time, the Arctic transport will already have to float over the Arctic ice using magnetic levitation or on gravity engines, and the heirs of the holding’s general designer N.S. Out of habit, Pavlenko will continue to promote the Mi-8 helicopter (prediction from ex. General AG Samusenko) and single-rotor helicopters with a tail jet engine from N.S. Pavlenko.

Old age is not a joy, even with a tail taxiway!

Vertopedia says: “The absence of power loss on the tail rotor (10 ... 12%), as well as a higher efficiency (by 15%) coaxial rotors at flight speeds up to 100 km / h with equal engine power, allow for higher thrust ( on 30%) carrier system. "

A helicopter with a taxiway at the rear will not have a tail rotor, but the main rotor thrust will remain 15% less than the coaxial, and a heavy tail boom will also be inherited. Taking into account the high price and weight of the tail taxiway with a fuel supply for it, it turns out that "horseradish is not sweeter!", Which, it seems to me, was not understood by the TsAGI scientists, since they are not designers. To this we must add the ability of the coaxial helicopter in hover mode to confidently withstand crosswinds, and then a logical question arises: is it worth continuing to "fence the garden" with single-rotor helicopters, especially since we have produced Ka-226 without any problems and have long been ready for serial production modern coaxial Ka-32-10AG helicopters.

But “Andrey Boginsky, proving the uniqueness of the results obtained at the Mil Design Bureau, says that the X-2 (USA) is, in fact, an expensive toy that can find very limited application. Since the maximum take-off weight of the X2 is 3,6 tons. The Russian flying laboratory exceeds these figures by 4 times. " (Ka-92 and Mi-X1: Catch up and overtake Sikorsky tehnowar.ru 2017-06-23).

With such verbal husk, he is trying to justify the fabulously large sums of money thrown into the conversion of a two-seat Mi-24 cockpit into a single one with the addition of two letters in the back: "LL" But taking into account the experience of the "expensive toy", the Americans have built and are already undergoing flight tests of an 18-seat coaxial helicopter SB-1 Defiant with the prospect of a cruising speed = 460k / h. Such a speed "solid" Mi-24-mu "LL" and in a dream never dreamed of, even the maximum, as well as a future helicopter from TsAGI with a tail taxiway. And then it is not difficult to guess that acrobatic dances around a single-rotor helicopter continue to be performed with only one purpose: to justify the torpedoing of real modern projects of Ka-92, Ka-102 helicopters and high-speed combat helicopters from the general designer of Kamov, Sergey Viktorovich Mikheev, which actually leads to undermining the defense capability and economy of our State! The bottom line is that if high-speed coaxial transport and combat (S-97) helicopters are already being tested in the hostile US, then there are no real high-speed helicopters in Russia, despite the fact that real projects of such helicopters from the Kamov company have long existed! It must be assumed that the empty chatter to A. Boginsky passed from gene. designer cost center N.S. Pavlenko, who 11 years ago assured everyone that his single-rotor Mi-X1 helicopter would reach a maximum speed of 520k / h, and the Mi-24 LL in June 2016. speed = 460k / h.

And giving the Pindos a gain in time, “effective” managers solve a second, very important task for themselves: replenish their bottomless pockets with the state budget.

And to the ministerial generals of the Russian Federation, I once again suggest that you read the recommendations of real polar explorers on the use of helicopters in the Arctic.

“In the Arctic, an experimental unloading of the supply vessel to the unequipped shore by the Ka-32 helicopter was carried out. The experienced polar explorer Mark Ivanovich Shevelev, Hero of the Soviet Union, participated in this experiment.

Recalls Mark Shevelev:

"It was necessary to supply the polar station on Bear Island with everything necessary for a long wintering. Typically, this operation in the Arctic takes a lot of time. There are no berths, snow, wind, on the pontoon you will not always come to the shore. In a word, people drag cargo in icy water, and even special suits are not saved here. It is especially difficult to manually drag fuel tanks. But everything must be moved as far as possible from the sea, beyond the maximum tide line. And so, in spite of the fog, with the help of the Ka-32 helicopter we finished unloading the vessel "Sasha Borodulin" in just one and a half days.

The helicopter picked up a container with a cargo of five tons from the deck and carried it to the island to the very house of the meteorological station. "

Why was it not possible to invite a rotorcraft to riggers and loaders before? The matter is that in the polar conditions only Ka-32 can be reliably used for work with ships. The helicopter successfully passed comprehensive tests. Sailors, scientists, pilots appreciated his great opportunities.

The commander of the division of helicopter pilots of civil aviation Valentin Andreev:

"Ka-32 even us, flying on helicopters of different designs, surprised. This compact robust has excellent engines. He has on board a superb flight navigation system and a computer with which you can fly in automatic mode over the ocean and day, and on a polar night without a drive station and dispatchers. Electronic equipment always keeps the right course. "

This machine is a find for the Arctic. Ka-32 helicopters as part of Arctic caravans will bring serious savings to the national economy. "(Feast on Bear Island, Faithful Course, World Records Ka-32.).

Since the Ka-32-10AG is designed on the basis of the flawless Ka-32 that has proven itself in the Arctic, today it is the most important helicopter for work in the Arctic, in the North and the Far East to work in polar conditions! It seems that the ministerial generals of the newspapers do not read and are not familiar with such recommendations of the true polar explorers, or are so full of food that for them is the first thing personal enrichment, well, and the defense of the State is THERE!

Dear ministerial generals, take a closer look at the payloads of helicopters with VK-2500 engines in each, perhaps this time you will still see a difference in favor of coaxial Ka-32-10AG, which just catches the eye!

Load capacity ... 

1. Coaxial helicopter Ka-32-10AG: on external sling - 7000kg.

2. The newest Mi-171A2 helicopter: on external sling - 5000 kg.

At the same time, the speed characteristics of the Ka-32-10AG are higher than those of the Mi-171A2, but the government of the Russian Federation has put into production (apparently to spite Russia) a frankly worse helicopter, namely the Mi-171A2!
