Helicopter Flooding

 

 

From the designers of the cost center, it seems that they work on the command "ZAMRI", so from the 80-ies they do not get new models of helicopters. In the film "The Magnificent Eight" gene. Designer A. Samusenko says that Mi-8 will fly for half a century. If you believe his words, the fate of our helicopter pilots is unenviable!

Great Mi-8 was in the last century, but today - a hymn to yesterday, a prominent General Designer Mikhail Leontievich Mile and shame today's General Designer of the cost centers, which are parasitic on the achievements of its creator, gradually reshaping its products are not producing anything new. The excessively high drag from Mi-8, typical for the middle of the last century, was compensated by the low price of kerosene of that time, which is unacceptable today because of the high cost of fuel. From here and a small flight range, so on the sides of the helicopter are hung additional fuel tanks, which increase the already large resistance of the helicopter, increasing it in general.

Compare: the newest (rebuilt Mi-8) Mi-171A2 in the Arctic version.

With side tremendous fuel tank prishpandorenny metal strips to the fuselage, in which in passing inscribed same hefty landing gear wheel with a very significant addition to the drag of the helicopter in flight, and behind another and tail rotor pulls back, but still part of the power robs carrier Screw.

ЛТХ(© 2017 JSC "Helicopters of Russia". Flight specifications):

  • Engines for gas turbine VK-2500PS-03

  • Power on take off mode 2400 hp

  • Capacity:

  • Inside the cargo cabin 4000 kg

  • On the external suspension 5000 kg.

  • Max. Speed ​​280k / h

  • Cruising speed 260k / h

  • Max. Range with the main tanks 800km

 

Kamovsky Ka-32-10AG is also in the Arctic version and with the same engines:

Accurate airplane aerodynamics without excesses on the sides, so it flies faster, farther and carries a useful cargo inside the fuselage - 5500kg. And on the external suspension -7000kg.

For the new helicopter from the cost center they can object: "And Mi-38 !?". Mi-38 is also a Soviet legacy, but the finished project can not be implemented for more than 30 years. Al. Samusenko called it a helicopter 21-th century. Krivit soul general: for LTH and even more on the safety of flights Mi-38 does not pull on the 21-th century. He has a beautiful, well-streamlined fuselage, but the product has grown old not so much by the length of service as in essence. Compare Mi-38 80-x gg. And Ka-32-10AG 2000-x gg: load capacity and speed are equal, although the Ka-32-10AG engines are slightly weaker. But coaxial helicopter due to the lack of the tail rotor is much more compact and maneuverable, especially when maneuvering at the ground, but most importantly - safer: in flight will not give up the tail rotor, followed by disaster, and the war is not cut off from large-caliber machine-gun tail boom or simply control the tail rotor, At which the flight ends equally sad. In the Ka-50 coaxial helicopter, during the in-flight tests, the tail beam was fired-he confidently flew to the aerodrome and quietly landed. At the same time for him on hovering and taking off without a difference - from which side the wind blows, which can not be said about helicopters with a tail propeller.

Promising helicopters 21-th century: coaxial Ka-92; Longitudinal scheme Ka-102; A marine helicopter "Lamprey", which has a cruising speed of -320k / h.

Of the overseas - high-speed coaxial Sikorsky S-97 with a design speed of 407k / h. And which is already being tested.

Helicopter trample.3

 

"The European Helicopter Airbus Helicopters Holding presented a draft long-term high-speed rotorcraft RACER (Rapid and Cost-Effective Rotorcraft, fast and cost-effective rotorcraft. 27iyunya 2017g.)

Helicopter trampling.

 

The very same scheme that was offered to them (the designers of the MVZ) in the last century, but it was not there - the tail screw for them - a balm for the soul, we can assume that Western designers are grateful to them for it. So the scheme was in Airbus, which patented it, with which you can congratulate the designers of the cost center, because this, from my point of view, first of all - their victory!

On the other hand, the very long-time response of the same designers evident that "In yet 1910godu founder domestic helicopter B.N.Yurev single-rotor helicopter patented schemes, which reactive torque compensation performed by two propellers performing additional functions in flight propulsion." Hence it can be concluded that this fact is the basis for our designers in the future to design and produce single-screw helicopters without a tail rotor - and no litigation over the Airbus patent!

I believe that it will be interesting for readers to get acquainted with the reaction of the specialists of the MVZ on this scheme at the end of the last century.

I was written: "Because The Mi-6 helicopter has wings, then at its base I will tell the proposed scheme of a single-rotor helicopter without a tail rotor. "

Answer: "The proposed Mi-6 helicopter upgrade project does not contain any new constructive solutions ... The conducted studies and design studies have convincingly proved the lack of advantages of rotorcrafts in comparison with helicopters as a measure of commercial load transported to a given range and in terms of transport performance. Therefore, at the moment no aircraft construction company in the world builds or designs rotorcraft. "

To tell on the basis of the Mi-6 helicopter a scheme with wing propellers is one and quite another - to "improve" it according to this scheme. Nobody will ever "improve" the aircraft in another way, but will design a new helicopter from scratch. Such nonsense could only arise in the minds of the former designers of the MVZ who were bored with the former glory.

Further - more: I write that the rotor of the helicopter Mi-24 is able to fly at speeds up to 500k / h. Answer: "For example, the statement that the rotor of the helicopter Mi-8 allows you to fly to the speed of 500k / h. Does not have any justification from the point of view of the aerodynamics of the screw is simply absurd. Ph.D., Ph.D. 9.4.86. BL Artamonov Design Engineer 1 category 09.04.86g VN Zhuravlev. "Mixed" Mi-8 and Mi-24 is not casual: this scripture had its purpose to humiliate me - as the author of the proposed scheme in order to later abandoned his idea. Naturally, designers with such moral qualities expect some positive progress in the helicopter industry - naivety, but today the author of these lampoons V.N. Zhuravlev has a doctorate in technical sciences.

Now a few words from the history of creating Mi-8. In May 1960. At the cost center, the development of a new helicopter began. The first experienced helicopterIn-8, With one engine made the first flight in June 1961 year, and with 1965g. The twin-engine Mi-8 has already started to be serially produced at a helicopter plant in Kazan. Then there were no computers, no experience in designing helicopters of this class with turboprop engines, like the engines themselves, but the helicopter came out in a very successful series in a short time.

The reason is simple: at that time the words "CORRUPTION" were not known, therefore Soviet helicopters occupied the leading position in the world and enjoyed steady demand in the world market, while at the exhibitions our designers did not cease to amaze the audience with novelty. For example, from our USSR to France, our giant of the transverse scheme flew by its own motion:

"But the spectacle of the B-12 helicopter, majestically floating above Le Bourget at a remarkably low noise level, despite its 26 000l.s power, hidden in the engine gondolas, makes one wonder: did almost all the helicopter industry go on the wrong path for about two decades." Such were the statements in the French and world press after the demonstration flight of the Soviet helicopter giant B-12 at the International Aviation and Space Salon in Le Bourget near Paris in June 1971. " (Helicopter, 2007 No.1> Page 24)

In 1970, M.L. Mil died and in mass production instead of B-12, a classic Mi-26 helicopter was launched, followed by its upgrades, after which the helicopter increased the cost, but not the performance characteristics (LTX). In connection with import substitution, it is planned to install PD-12V engines on it, which again will raise the cost. At one time, when there was no dictator Peter Poroshenko in Ukraine, Vyacheslav Boguslayev, the head of the board and the board of directors of the engine building company of Motor Sich JSC (Zaporozhye), offered to join the UAC without any conditions, "but Russians do not want" (10.09.2012g News of the MIC). And today "Russian helicopters are forced to fly on" gray "engines ... Ukrainian company" Motor Sich "continues to actively cooperate with Russian enterprises. The company continues to supply engines for Russian helicopters either directly or through "gray schemes" through Belarus. (19.08.2016Internet publication "New look").

But let's return to the Mi-21 "38" helicopter. From the newspaper"Version" (Imaginary achievements and real failures of the holding company "Russian Helicopters" Published: 11.04.2016) we learn that "the estimated estimated cost of Mi-38 starts from 40 million dollars", and it will be produced at the Kazan Helicopter Plant and the first shipment of helicopters will go to the VCS and MES. But further problems will arise with the sale of these helicopters, because Mi-171A2 will be produced in Ulan Ude with similar aircrafts, but much cheaper, and our customers have started to refuse from Mi-8 because of his old age, which will affect the work of the KVZ.

At first the situation will be saved by the light Ansat helicopter, after which the KVZ leaders will be forced to launch an average helicopter of their own design, which I hope the Tatarstan Government will help in order to avoid unemployment at the plant. It is possible that this will be a helicopter of a transverse scheme with blades of the main rotor from Ansat and very useful would be an electric control system for rotor screws developed for Ansatov. I believe that the RD-600 engines would be very suitable for carrying Ansat's propellers, but even at the testing stage financing was stopped for the sake of the French. It is understandable, because as with the French engines you can "cut down" the good grandmothers, and with our engines you will pay a lot!

As for State care and responsibility, then we have a President! And everything would be fine, only to be blown away for inhuman corruption directly to the operators, and pilots sometimes lives, because the tail rotor, this screw is the killer, which the leaders of the holding know very well, but still instead of the economically more profitable and safer Ka-32 -10AG launch in a series of Mi-171A2 helicopters for the joy of yours!

To better understand the end of the flight after the tail rotor failure, I recommend watching these videos. Similar failures occur in all helicopters with tail rotors, and Mi-26 even a whole tail boom fell off.

Yet. A video of the Mi-17 helicopter crash appeared in the network, in which Afghan general Mohadine Gori, commander of one of the seven army corps, was killed.

 

While the article was being written, the proposal of President Vladimir Putin appeared in print

Vedomosti newspaper 18 of July

President Vladimir Putin invited oil and gas companies to purchase for their needs not foreign aircraft, but domestic.

"Without delaying, we need to think and guarantee the loading of production capacities, generate demand from civilian customers, including our oil and gas companies and other corporations with state participation," Putin said at a meeting on civil aviation development.

According to him, for their own needs they purchase aircraft equipment abroad and "in considerable quantities". Putin believes that such an approach needs to be changed: "We have already talked with the heads of our companies more than once: give preference to domestic technology, provided, of course, that it is not inferior, but, preferably, superior in quality to foreign counterparts."

"Provided, of course, that it is not inferior, but, preferably, superior in quality to foreign counterparts".

 

Here, as a rule, there is a substitution, or rather a fraud to the President, as in his time:

"The first serial helicopter Mi-28-M" Night Hunter "entered service with the Russian Army? The vice-premier, the head of the Ministry of Defense Sergey Ivanov informed the president. According to him, its combat and technical characteristics of the Mi-28-M are four to five times greater than our current mass Mi-24 helicopter. (Regnum .05.06.2006). "

Result - rather prominent, the world's best combat helicopter Ka-50 «Black Shark" on the arms of our army was adopted raw, not reliable and slabomanevrenny (compared to the Ka-50) «Night hunter", who during this time had to carry out the lives of four High-class pilots, not counting financial costs after disasters and aurii.

A similar creeping result goes even today, when instead of the safer and more cost-effective Ka-32-10AG, Mi-171A2 is launched into the series with clearly worse performance. The trouble with the outstanding Ka helicopters is that their General Designer, Sergei Viktorovich Mikheev, is mean to bribes and there is no doubt that he is "incorrigible" in this matter!

Today, another good news for the KVZ "Given the tasks facing the Russian Defense Ministry, in our opinion, there is a need for both modernized Mi-14 helicopters and a promising amphibious helicopter," the holding believes. (Military Industrial Courier 19 July, 2017).

It is impossible to admit the holding's ability to bankrupt such a powerful factory. Such an attempt they had to address the helicopter plant in Kumertau, tried to deprive our State of the release of unique coaxial helicopters. But the international contest was won by Ka-226 and the Indians ordered 200 of such helicopters, which saved the plant in Kumertau.

And it began with a simple one: "It is known that with the arrival of the Russian Helicopters at KumAPP, prices, for example, on Ka-32, grew by one and a half times - Eugene Matveev wrote about this in 2012, N.E. .. "(Argumenty.Nedeli.N 18 (459) from 21.05.2015" Manturovsky falcons "are smashing the helicopter plant ...). The plant from the bankruptcy was saved by the fact that the Ka-226 helicopter won the international contest, after which the Indians ordered 200 Ka-226 helicopters.

I am glad that there are people who can tell the truth clearly and clearly! Certainly our helicopter industry now has nothing to boast about, except for the already almost ruined beautiful developments. Our designers are afraid of panicking to explore promising schemes - two-screw transversal and longitudinal (and in the pursuit of compactness and synchrocopter it is not a sin to remember), to apply a number of unconventional Decisions ... Of course, in the yard of capitalism ...

I'm certainly not an aircraft designer, but I'm fond of aviation since childhood. This article, actually reported to the president and I think everything is very popularly stated. Only will it reach the top? And it's time to think at the top who "rules the ball".
