Previous article: 'Good MI-26, yes dórog " It ended with the words:
"I hope that designers MVZ finally pluck up the courage and obtain patent scheme with the third theater on a wing KB Mil. Mil ".

Vain hope:

"Airbus patented the concept of the helicopter to" at least one elevating motor rotor and bearing at least one pair of wings, at least a pair of horizontal thrust engines, one on the right and left. "
That is, any repeated the scheme, or at least trying to do something with traction motors on the sides, in any arrangement and combination, automatically turns the infringer of the patent watermelon. "

But this is a truly Russian scheme established Bratukhina IP even in times of "tsarya- Peas»: Russian Aviation Museum Bratuhin 11-EA 1936.

Well, if she peered Airbus better than the general designer of the cost center, they and good luck !!!
Raikin: "Where do you work? - Under construction. - What are you doing? - Yes. " In KB MVZ "Smoke" from the beginning of 80-ies, after the launch of a series of heavyweight Mi-26 under the leadership of MN Tishchenko.

The State Duma was a proposal on restoration of the Ministry of Aviation Industry (MAP). It is logical! Engineering excellence, grow and needs that need to know, understand and meet the holding company "Russian Helicopters". But it must be so, but in fact Holding - a mediator, appropriating, and inhibitory developments helicopter constructors, so the production of helicopter factories. In the Soviet Marie positions occupied by specialists rather than effective managers of sociologists and linguists, specialists of "buy-sell" a trade education on such -Taburetkina Serdyukov.

For example, if the holding company "Russian Helicopters" are not deprived of "Kamov" finance projects Ka-Ka-92 and 102 in 2008godu in favor of virtual Mi-H1, we would today have ended trials of modern high-speed transport helicopters. Syria has shown that in such helicopters in great need of our videoconferencing and the Navy; they need and rebuilding the military towns of the Arctic shelf with flights, etc.

But for the maintenance of gas pipelines with frequent landings, oil rigs, to work with an external suspension and fly a short distance, when taking off and landing over 15-30min. flying, high-speed helicopters would not be cost-effective, there is the exactly - helicopters Ka-32-10AG, ie and they will be in demand in the economy, and others.
Also for a long time there is a need in helicopters of lower carrying capacity. At one time, NI Kamov offered Aeroflot to replace the Mi-4 helicopter with a coaxial Ka-25 scheme. It had two engines with a total power = 1800l.s. (On Mi-4 there was one engine with power = 1700hl), Ka-25 with the same carrying capacity had much better speed characteristics and much more power reserve. But, as the malicious tongues spoke, MLMil crushed it with his authority and after the withdrawal of Mi-4 helicopters from operation, various commissions overfly the gas pipeline and other areas on Mi-8 helicopters of an amount of 6-10 people, i.e. With loading less than half the possible.

Even against the tail helicopters would like to add that such in-you are very dangerous from the start to the stop screws, so from them for a long time should be abandoned, and freebies for a comfortable life, General Designer MVZ will suffice for a long time, while the Mi-8 yes Mi-24 / 28 not exhausted their resources.
Speaking of MAPE. Soon (maybe sooner) will start serial production of the Mi-38, but the most interesting thing in this moment is that the holding of a series of parallel launches Mi-171A2 factory in Ulan-Ude - a direct competitor to the Mi-38. Mi-171A2 will be cheaper, respectively, and the demand for helicopters Kazan plant, I think, will fall slowly, followed by bankruptcy.

Therefore, the management of KHP stóit likely provide such an option, but in its strategy program countermeasures:

  1. fine-tune the production and sale of "ANSAT" helicopters;

  2. reflect on the future replacement of helicopters Mi-8 / 38 on its own initiative, for example on the basis of the same helicopter design vertibirds transverse scheme taking into account the strengths and mistakes Ka-22 and B-12.

I am convinced that the two catastrophes of Ka-22 were sabotage, for both in the OKB "Kamov" they did not rape both the speed and the overloads - nothing broke off, there were no breaks, no breaks, and no catastrophes. And in the second run, in both rotors, an attempt was made to organize a leak of oil: "According to the flight log of the navigator, the Ka-22M 01-01 rotorcraft took off at 3 an hour 57 minutes, but soon returned due to a malfunction (leakage of oil from under the tightly closed oil bottle of the left Reducer) and in 4 hours 10 minutes landed. At 4 an hour 55 minutes took a second flight and an hour later - landing in Turkestan. There was already a rotorcraft 01-03 Garnaev, who had smoke before landing in the cockpit. On inspection, the nut of the left support of the synchronization shaft was turned off. Inspected and refueled the car 01-01. According to the explanation of the mechanic Yu. T. Denisov, there was discovered and eliminated the play of the slot-hinge of the left automaton-skew. " (First flight: 1960).

What happens in such cases - motorists know that the engine of the wedge! The number is not passed, because vertibirds flown by pilots of the highest class, then for maintenance after planting was introduced in Turkestan proven defect that prevented then determine the causes of accidents in both cases.

I am sure - if serving tehbrigady were in flight, along with the crews in the rotary-wing, all vertibirds to arrive at your destination without flying accidents!
Just a couple of words on the rotorcraft Ka-22. In describing his cruising speed = 270k / h., But in fact it was more than 300k / h., Its empty weight by nearly half a ton lighter Mi-6 with the same maximum takeoff weight = 42,5t. This means that the motors have the same, and they are built from the same iron, hence the price they are equal, and rotorcraft performance would be much higher!

That's me to the fact that there is a complete sense to repeat the scheme rotorcraft Ka-22 with great benefits for the State and the manufacturer. In addition, NI Kamov built it after the tiny Ka-15, and even KHP "ANSAT" much more, not to mention the serial Mi-8.

During the tests, the Ka-22 speed reached 375k / h. And this with engines in power is less than the calculated ones for 800l.s. And a rotor with blades of obsolete (trapezoidal) construction. Excessive resistance was given by the cockpit of the pilots over the fuselage, and the chassis of an unreasonably large amount strongly hampered the rotorcraft in flight, so without doubt that for the modern rotorcraft there will be an ordinary cruising speed of 340-360 / h. And there is no point to bypass this modern rotary wing scheme, besides it is not so hot as it is complex! I also add that in modern rotorcraft, propellers should be made with coaxial propellers and for safety to ground personnel and passengers - trapped.

Chassis even the high-speed rotary wing can be made non-retractable, but with low drag, keeping in mind that it's not a plane and even take-off it is an aircraft is able to get off the ground at speed = 60k / h.
And for the rear of the truck and shutters - an example of AN-26 / 12.

Bullshit - you can not patent something that has long done. Let the wheel and then just patent

For the first time in a long time I hear a voice of common sense about the future of vertically taking-off vehicles. Modern aircraft construction has become obsessed with a primitive, imperfect classical scheme of the "tailed" helicopter. We are on the spot in spite of the excellent engineering developments, to which B-12 and Ka-22 are fairly attributed. It's time to develop a modern heavy helicopter of a two- or three-screw scheme, which will give much better possibilities both in terms of load capacity and speed. A promising one is the "helicopter" The interaction of horizontal and vertical screws. All business in a position of a management mentioned in article of departments!
