"In this age of progress and progressivki" (Raikin).

Bonuses for overfulfilment of the plan were called progress in the USSR in the common people. Once in the bath, V. Vysotsky sang a song: "And we are needed in Paris - like in a bath of pliers" One man burst into laughter. Vladimir Semenovich inquired about the reason, to which he replied: "How do you know that there are a lot of nails in our bath?" And I went there too: “How did A. Raikin know that in Russia one helicopter design bureau would work for progress, and the other for“ progressive ”. For example, the Ka-50 in a fair competition three times in a row wins the competition from the Mi-28 to replace the outdated Mi-24, but Mikhailov (ex. Commander-in-Chief of the Air Force) expressed confidence that the new MI-28N combat helicopter, named ", a" nice green street "will be given. (Lenta.ru. Russian Air Force began testing "Night Hunter" June 2005).

On this occasion, ex-Minister of Defense S. Ivanov generously allocates money for its development: "In 2004, the Ministry of Defense spent several hundred million rubles on the development of the Mi-28N project. In the state defense order 2005, the manufacture of the installation lot Mi-28N is being considered. As for Ka-50, this year the Kamovians got about 100 less money. ... But the questions from the series "what the army needs" are solved, as we know, not in the field, but in warm offices. " (The Ministry of Defense decides which helicopter will be the main armament of the Russian army.) Source: "Lenta.Ru." Published: 29.10.2004). In the "Kamov" during this time, on the handouts "from the master's table" the Ka-50 / 52 helicopters were perfected and made them with outstanding characteristics, and Mi-28H both was and was not brought to "mind", so for a short Service managed to take the lives of four highly professional pilots. The last catastrophe is in Syria.

The Mil Moscow Helicopter Plant’s MVZ is like a court helicopter design bureau, hence the total stagnation in helicopter construction for more than 30. In the movie “The Magnificent Eight”, MVG Designer General AG Samusenko proudly declares that Mi-8 will fly another 50. And now it is expected to release a series of upgraded Mi-8: Mi-171А2.

Mi-172A2 gas turbine engines VK-2500PS-03
Power takeoff 2400 hp

Capacity:

  • Inside the cargo cabin 4000 kg 

  • On the external sling 5000 kg

  • (Data from the site "Russian Helicopters).

To better understand how this corresponds to the time the helicopter flight characteristics compare it with a similar upgrade of the coaxial Ka-32 under the symbol Ka-32-10AG with the same engine and cabin size commensurate helicopter Mi-8.

"The main areas of modernization: 

  • 1. Increased capacity to 26 people and increase cabin comfort.

  • 2. Replacement engines TV3-117VM on VC-2500.

  • 3. Increasing the duty to 5500 kg inside the cabin and to 7000 kg on external sling.

  • 4. Installing a new set of on-board CCD-226AG equipment to perform instrument flight over bezorientirnoy terrain or sea landing on offshore platforms and offshore vessels in the meteorological conditions at SMU: 30 300 to m.

  • 5. Installation of additional external fuel tanks to increase flight range of up to 1200 km.

  • 6. Providing ditching and rescue people at the water landing.

  • 7. Basing on offshore platforms, ships, etc. (2007g). " (Ka-32 add weight 25.04 2007 Source:. AviaPort site)

Greater payload on 1,5t. the Ka-32-10AG is simply explained: a part of the power is not expended on the tail rotor; coaxial screws have more efficiency, i.e. at the same power, more thrust is delivered; due to the lack of heavy tail and end beams of a coaxial helicopter, the coaxial lighter of a classical design is lighter than a helicopter. And we must not forget that with the absence of a tail rotor, the helicopter becomes much safer from take-off to landing, while the series will not be cheaper and perfect Ka-32-10AG, and Mi-171-2. 
At Mil mass production expected another helicopter Mi-38, the beginning of the design of which belongs to the first half of 80-ies of the last century.

Gene. Designer MVZ A.G.Samusenko 21veka called him by helicopter, but it is nothing more than a PR, what is not hard to verify, by comparing the flight capabilities of Mi-38 with modern design Ka-92.
Mi-38. Turbine engines 2hTV7-117V power takeoff 2500l.s mode. Cruising speed 280-290km / hour. Range with cargo weighing 3000kg 900km Range with additional fuel tanks and cargo 2700kg 1200km. (The site "Russian Helicopters").
The project is co-axial helicopter with rigid blades Ka-92.

Ka-92. Cruising speed - 420-430 km / h Maximum speed - 500 km / h. Range - 1400 km. Commercial loading - 30 passengers Takeoff weight - 16 tons.
As the power plant during the first two models of the engine Klimov VK-2500 be used. On production models planned to install new engines VC-3000 characterized by improved performance. (Wikipedia).

"According to Sergei Mikheev, Ka-92 from 30 oilmen-shift workers on board could, for example, flying from Murmansk fly to oil platforms in the area of ​​the Shtokman field, the remote on 635 km, at a cost of only a half-hour flight (cruising 420 speed km / h). At the same time, if the weather does not allow for the landing on the platform, the helicopter was able to return home at the airfield without refueling "(faster and farther," Kamov "is Ka-92 project).
As you can see, the range of the flight of the Mi-38 is inferior to the coaxial, but there is nothing to argue for speed! Moreover, in the Mi-38 load rating feature, I noticed a fake description. 
The site "Helicopters of Russia", we read: Flight range with cargo weight 3000kg 900km Flight range with additional fuel tanks and cargo 2700kg 1200km, i.e. If you believe these figures, it turns out that the hourly fuel consumption of the Mi-38 = 300kg / hour (3000kg.- 2700kg.), which is not true. 

As fuel consumption refine the amount of load on 1200km, for which we find a difference in this same range 1200km. - 900km. = 300km that Mi-38 cruising speed 290k / h. fly over ~ 1chas. Engine fuel consumption TV7-117 = 800kg / hour, then it at a distance 1200km not require additional fuel 300kg as herein 800kg and which is filled by loading. At the output we get from this: 3000kg.-800kg. = 2200kg., I.e. 2700kg instead. the description of Mi-38 helicopter at a distance of 1200km. will be able to carry the maximum load weight = 2200kg., and the flight = 4ch.14min.

In Ka-92 on 1200km. Useful load is 3000kg. and flight time = 2ch.51min. This shows that the Mi-38 and close does not correspond to the request for a helicopter A.G.Samusenko 21veka? As it is designed in 20 century, it will remain as such for the rest of his life, even if his next film called his helicopter 22veka.
In the end, I propose to compare the projects of helicopters with a tail rotor and a longitudinal scheme assuming the same take-off weight = 30т. 
Classical scheme Mi-46

Zhukovsky: heavy transport helicopter project - Mi-46 (4sent 2007g)
Mi-46. Designing machines Mi-46 is based on the scientific and technological potential, obtained by the creation of Mi-Mi-26 and 38. Maximum take-off weight of the helicopter 30 t Cruising speed -. 270 km / h. Static ceiling - 2,3 thousand meters Dynamic ceiling -. 5 thousand meters Practical flight range -. 400 km. Mi-46 60 will carry passengers or cargo weighing up to 10-12 t.

Longitudinal scheme Ka-102

According to our calculations, the Ka-102 can have a speed of up to 500 km / h. At the same time, it will transport up to 80-90 passengers, having a take-off mass of about 30 t. ... And the longitudinal scheme allows you to have a longer fuselage, which comfortably accommodates a much larger number of passengers. 
(Sergey Mikheev: a helicopter with a rigid rotor - to "airplane" rates).
Maximum flight distance: 1100 km. 
No comment.

 

Vitalii Belyaev.

Dear Oleg, from Mi-8 cruising speed = 230k / hr., While Mi-38 with the same blade on the description from the "Russian Helicopters" = 285k / h. Therefore, more aerodynamic fuselage and Mi-171A2 had the same cruising speed of 285k / h.
According to Ka-32-10AG: "If it was real it would really funded Defense and the Navy to replace the SC-27."
What do you say on the subject: a combat helicopter Ka-50 "Black Shark" was a real helicopter, which the Mi-28N and "hold a candle" is not necessary, but the former. Defense Minister Sergei Ivanov relieves weapons Ka-50 and instead gives the Army a dead Mi-28N. As in Syria killed the entire crew when it drops, then blame attributed to the crew. In our time, this conclusion is "fair" fees become the norm.

Variants with longitudinal screws were SSSRe earlier than the state, but these options are not with those friends. After all, before the budget money was simply not possible zatyret pockets, and there were people who harmed the country just out of friendship.

With the MI-38 not very nice poluchaetsya.kazhetsya it is, but in reality it is not, and it seems to be not.

Vitaliy, a good review. But you probably do not know the design of helicopters. The problem is our helicopter engines and the carrier system. Even on new helicopters do not install blades with high-speed profiles. Your comparison of the Mi-8 extreme modification and the prospective Ka-32-10AG is not quite correct. If it were real it would have been financed by the MO and the Navy to replace the KA-27. Mi-8 is already run-in and takes its place. Kashka is only on paper. By the task that you set out, the porridge will be more difficult and more expensive. Until the issue is solved by balancing the blades of the coaxial system, one can not speak of high speeds. That spacing that on all the gruel gives great resistance. Milevskie also can not add speed due to the lack of a high-speed carrier system. It's not the KB, but the stagnation of those thoughts, and the lack of desire to lick the Eurocopters or the Sikorski

And nothing in our country changes in this direction, this is the tradition of someone who is closer to the reigning, he receives both money and orders. Let us remember how before the Second World War, I-180 Polikarpov was stabbed and the production of a lousy Yak-1, and generally useless LAGG-3 Then Tupolev extinguished his competitors for many years, as a result, many good projects were pohery.Ekranoplanes fell under the same baton Then the confrontation between Su and MiG, which actually ended in the death of the second ... with a probability of no more than 50%. That is, it can fly, or maybe not. So everything is still in our kingdom, nothing changes. The right is not the one who is right, but the one who has more rights. In this case, who is closer to the court ...

I, too, do not understand why the "Black Shark" is worse than "Night Hunter" Explain who can.

Yes, the difference is great. The allocation of money for MI is not justified by anything. With the person making such a decision, it seems, they "flew to hunt" for MI, and more than once. M still ... Ugh! So, in Chechnya, with the joint use of MI and SC, the combat advantages of SC were revealed. How long?

Hello! With this notorious Competition, so much financial loss has already been incurred !!! A madhouse which is, well, why do we need to copy everything to the west one to one ???? !!!! For God's sake compete, but the conclusions must be made by the head, and not at the expense of the Lobby! This is all the Serdyuk legacy, when they will finally conduct a tough and impartial investigation of all these abuses. Uniquely Kamovsky helicopter is steeper, due to the greater payload still raise armor protection, he generally will not be the price !! Milevsky KB, no one wants to close, let them do it, but they do not keep up with the flight characteristics, why all the money in them is hammered, and the progressive design bureau is working honestly, We need to redistribute all resources with a turn to 180 degrees and see how they survive, Not correctly it: Due to old merits to live !!

The legacy is not Serdyukovskoe, but the Soviet one. The lobby was just there, as the helicopter market in the Union was absent as a class. And the customer and the buyer was only one state. As for the best of the modernized Ka-32, then on paper you can draw any numbers, but the Milev project, although worse (?), Is in the gland.
