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

Progressive in the USSR in the common people called bonuses for overfulfilment of the plan. Once in a bath V.Vysotsky sang a song: "And we are needed in Paris - as in a plumbing bath" One peasant burst into laughter. Vladimir Semyonovich asked why he replied: "How do you know that there are many nails in our bathhouse?" And I went there: "And where did Raikin know that in Russia one helicopter design bureau will work for progress, and the other - to "progressives". For example, Ka-50 won a fair competition three times in a row from Mi-28 to replace the outdated Mi-24, but "Mikhailov (former Air Force Commander) expressed his confidence that the new MI-28N combat helicopter, entitled" Night Hunter ", A" good green street "will be given. (Lenta.ru.The Russian Air Force began to experience the "Night Hunter" June 2005g).

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.

Mil Moscow Helicopter Plant is like a court helicopter CB, hence the complete stagnation in the helicopter already 30-plus years. In the movie "The Magnificent Eight" General Designer MVZ A.G.Samusenko proudly declares that the Mi-8 will fly even 50let. And it is expected to release a series of modernized Mi-8: Mu-171A2.

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

Capacity:

  • Inside the cargo compartment 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 directions 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 capacity at 1,5t. in Ka-32-10AG explained simply: power is not consumed on the part of the tail rotor; have coaxial screws greater efficiency, ie, at the same power it gives greater traction; due to lack of co-axial helicopter and heavy tail end beams constructively easier soosnik helicopter classical scheme. And we must not forget that with the lack of the tail rotor helicopter becomes much safer from takeoff to landing, with a series goes cheaper and perfect Ka-32-10AG and Mi-171A2.
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, in the range of Mi-38 flight soosniku inferior, and for the speed and there is nothing to argue! Moreover, in the characteristic by capacity Mi-38 I saw hypocrisy in the description.
The site "Russian Helicopters", read: Range with cargo weighing 3000kg 900km Range with additional fuel tanks and cargo 2700kg 1200km, ie according to these figures, it turns out that the time fuel consumption Mi-38 = 300kg / h (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.
At the end of the offer compared with the helicopter tail rotor designs and longitudinal scheme involving the same takeoff weight = 30t.
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

 

«Upside down» .6

 

 
According to our calculations, the Ka-102 can have speeds of up to 500 km / h. He will carry up to 80-90 passengers, with takeoff weight of about 30 t. ... A longitudinal scheme allows you to have a longer fuselage, which accommodate a much larger number of passengers.
(Sergey Mikheev: a helicopter with a rigid rotor - to "airplane" rates).
Maximum flight distance: 1100 km.

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 has changed in this direction, it's a tradition that is closer to the reigning ones, and he receives money and orders. Just like before the Second World War, Polikarpov's I-180 was stabbed and started producing a lousy YAK-1, and generally useless LAGG-3 . Then Tupolev for many years extinguished his competitors, as a result, many good projects were pohereny.Ekranoplany under the same club hit Then the confrontation of Su and MiG, which ended in fact the death of the second .. And the last example is the "Bulava", whose launch can be successful With a probability of not more than 50%. Zhet to fly, and maybe net.Tak everything is still in our kingdom, nothing changes. It's 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 what "Black Shark" worse "Night Hunter" Explain who can.

Yes, the difference is great. Allocation money for MI, is not justified. On receiving such a decision, it seems, "flew on the hunt" on MI, and more than once. M still ... Ugh! So, in Chechnya, in a joint application MI and SC, the SC found fighting benefits. 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 !!
