"The armor is strong," and the helicopters are slow-moving

"Helicopter Fortress": VCS of Russia is reinforced with 19.09.2017 assault helicopters.

The new Mi-8 "Terminator" will provide superiority ...

Powerful gas turbine engines Klimov VK-2500-03, a new auxiliary power plant TA-14, as well as a fully-updated avionics make the "Terminator", in fact, another helicopter that inherited from its predecessor the best - the design and was filled with modern content. This time the helicopter was thoroughly booked in order to make an effective attack aircraft from it. On the case went a new domestic metal-ceramic armor - lightweight and durable composite. ... The armor protects the crew, engine and important technological units of the helicopter from the turn of the machine gun in the caliber of 12,7 mm.

The new Mi-8 is not inferior to Mi-24 by the nomenclature of used weapons. ... "(politrussia, the Armed Forces).

"Armor protects the crew, ..." After the Mi-28N - almost "flying tank"!

But the trouble is that the “tanks” of the classical scheme do not have a protected tail boom, and, as a rule, they shoot at the helicopter from behind. The fact is that they fly in pairs at low altitudes, and cruising speeds are not so hot, so they are first allowed to pass and then fire at them from small arms and are not visible to the pilots from where they come from. The tail rotor control is interrupted, and you can also cut off the tail boom from a large-caliber machine gun, because it is under constant pressure from the tail rotor for a bending moment, and a twisting moment also acts on it through the end beam.

How vulnerable the tail rotor is - the militants in Syria filmed the moment of a missile crashing around this propeller of the Mi-35 helicopter: “After the rocket hit, the helicopter lost control and went into uncontrolled rotation.” A few seconds later the helicopter crashed to the ground and immediately exploded - the detonated fuel remains in the tanks turned the car into a pile of scrap metal. There was no chance of escape from the crew. ” (Downed in Syria, the Mi-35M got into the tail ... lenta.ru.2016 / 07 / 09).

Or even simply refuses to control the xv. screw and the sad end of the flight is the same: "06 December 2016. The web hosts a video of the crash of the Mi-17 helicopter, in which Afghan general Mohadine Gori, who commanded one of the seven army corps of the country, was killed. The recording was posted on LiveLeak. The ship collapsed 29 November. It is noted that the accident occurred as a result of a technical malfunction. The helicopter has failed the rear propeller. "

The tail rotor with a beam is a pain point of a helicopter, so a failure of a tail rotor in a helicopter’s construction of a combat helicopter would mean the same thing for protection if xv. beam made of "reinforced concrete". A helicopter without xB. Screws easier, more maneuverable, more reliable and more productive, i.e. more profitable!

It was possible to understand the helicopter designers of the last century, when the hv. the screws did not have an alternative, but at the cost center another 30 ago was proposed a scheme of a single-rotor helicopter without a tail rotor.

Excerpt from the answer: “Now about the tail boom, which you propose simply to reject. If you familiarize yourself with the design of helicopters, which do not have the task of compensating the jet moment and there are no tail rotors (TsAGI rotary wings 11-EA, Ka-22, coaxial and transverse helicopters), you will see that all of them still have a tail boom, which is located quite large in area horizontal and vertical tail. S.S. 9.04.86 B.L. Artamonov. 1 Category Design Engineer 9.04.86g. V.N. Zhuravlev (today - doctor of technical sciences).

By the way, Ka-22 does not have XB. beams, there is a tail part of the fuselage, on which the tail assembly is attached, and in TsAGI 11 –EA the keel mount generally begins almost immediately behind the cockpit. Most likely, V.N. Zhuravleva at that time was unimportant with his eyesight, but at the same time I do not see anything negative if the helicopter of the coaxial Ka-27 scheme has xl. beam: it does not have an intermediate gearbox, there is no end beam with a tail gearbox and a screw, therefore it is several times lighter than xv. The helicopter beams of the classical scheme do not burden the helicopter during maneuvering like the Mi-28 or Mi-8, but on the contrary, it helps with the tail fin.

Here is the rotorcraft scheme, which after processing it professionally surfaced in Eurocopter. (Patent №2445236 - High-speed hybrid helicopter ... Priorities: filing of the application: 2008-04-25).

"Armor is strong," and helicopters are slow. 1

“... In such circumstances, a typical task corresponds, for example, to transporting 16 passengers at a speed of 220 nodes (kt) in a vehicle having a mass of approximately 8 metric tons (t) for delivery to a sea miles 400 distance (n.miles), at an altitude of 1500 meters (m) in international standard atmosphere (ISA) conditions that define the standard atmosphere.

Such performance characteristics are highly exceptional in comparison with the performance characteristics of a standard helicopter, for example, the AS 332 MKII type, the applicant, even though its performance is already remarkable, particularly for similar tonnage: the recommended cruising speed of the 141 unit for a similar distance and the fast cruising speed of the 153 node.

High-speed hybrid helicopter with a large radius ... ".

"Such performance characteristics are HIGHLY EXCLUSIVE in comparison with the performance characteristics of a standard helicopter", but the general MVZ Pavlenko NS and (ex) Samusenko AG It is necessary to assume the tail screw with the wisdom of ML. Mila still gives dibs, but in new projects, on the contrary, one should invest money!

But I'm interested in another thing: our dear President Vladimir Putin, who at one time admired Ka-50's flight, does not notice our defense, and indeed our whole economy from the designers of the MVZ and the holding company Helicopters of Russia,

"Progress" aircraft builders ready for serial production of the world's best combat helicopters

Prime Minister Vladimir Putin keeps his promise. Almost immediately after his return from Vladivostok, the head of government said on Russian radio that the first Kamov helicopter of the serial production of the Arsenyev air-building company Progress will be sent to Chechnya. And he was inspired by such a statement most likely the presentation of a supermachine, organized by the governor Evgeny Nazdratenko. V. Putin was shown flight performance of the "Black Shark", specially flown from Arseniev to Vladivostok. It was piloted by test pilot 1 class Colonel Vladimir Horev. The participant of battles in Afghanistan, who fought on universal helicopters of general fire support "Mi-8", the gentleman of several military orders. Here is how V. Horev conveys the impression of the prime minister who personally congratulated the pilot immediately after the helicopter landed:

- Even in the face of Vladimir Putin it was clear that he appreciated our car. And he said shortly: "This is the technique - the spirit captures!"

And it is completely incomprehensible to the fact that after the demonstrative flights of the Ka-50, the President did not believe his eyes, but believed the ex-lies. Minister of Defense S.Ivanov and now to defend the State instead of the outstanding, best-in-the-world attack helicopter Ka-50, the Black Shark is supplied with a mediocre and, moreover, crude Mi-28H.

Putin's just calls to the military-industrial complex sound today:

"Our army and navy must possess the most advanced weapons, military and special equipment, which take into account, among other things, possible changes in the strategy and tactics of armed struggle in the future and are on the level, and better than foreign counterparts. Because if we want to be ahead, if we want to win, we must be the best. The key indicators of the program (state arms programs - ed.) Should first of all ensure a guaranteed strategic deterrence, and in the event of a potential external threat - its effective neutralization

- Putin said, opening on Monday (20.11.2017) a series of meetings on the development of the Russian defense industry complex. "

Helicopters Ka-52 "Alligator" confidently carried out "effective neutralization" of the tanks of militants, but not "Night hunters".

"The armor is strong," and the helicopters are slow.

These griefs - “hunters” occupy the last places in all competitions, and they continue to arm our aircraft, whereas they should be removed from service for a long time, and our army pilots transplanted to reliable and maneuverable Ka-50; instead of the flying “fortress” Mi-8 “Terminator”, launch a compact, faster and safer Ka-32-10AG series.

And this is what the Mi helicopters might look like today, if they had accepted a proposal for a single-rotor helicopter without a hub. screw

"The armor is strong," and the helicopters are slow.

instead of the classical scheme invented by our scientist at the beginning of the last century: "In 1910-1911. Boris Nikolayevich Yuryev, now an academician, winner of the Stalin Prize, proposed a single-screw scheme of a helicopter with a steering screw and built a helicopter over it.

Another scheme of the helicopter BN Yuryev became a classical scheme, according to which most helicopters are now being built "(avia.pro).

And here is the news: "New combat training helicopters Mi-28UB is planned to be tested in Syria. Published by 07.08.2017.AviaRu". It's time: the war has come to an end, so you can safely send to the test in Syria Mi-28UB. In advance, I congratulate the designers of the MVZ with the successful completion of tests in "combat" conditions "!!!
