"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 here's the trouble - the "tanks" of the classical scheme do not have a protected tail boom, but 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 they open fire on them from small arms and from behind the pilots cannot see: from what and where the fire is being fired. The tail rotor control is interrupted, and the tail boom itself can be chopped off from the large-caliber machine gun, because it is under constant pressure from the tail rotor at the bending moment, and a twisting moment also acts on it through the end boom.

How vulnerable the tail rotor is - militants in Syria filmed the moment when a rocket exploded in the vicinity of this propeller of a Mi-35 helicopter: “After the missile hit, the helicopter lost control and“ went into uncontrolled rotation ”. A few seconds later the helicopter crashed to the ground and immediately exploded - detonating remnants of fuel in the tanks turned the car into a heap of scrap metal. The crew had no chance to escape. " (The Mi-35M shot down in Syria was hit in 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. "

A tail rotor with a beam is a painful point of a helicopter, therefore, REFUSAL from a tail rotor in a helicopter design for combat helicopters would mean the same for protection if xv. the beam is made of "reinforced concrete". A helicopter without hv. propeller is lighter, more maneuverable, more reliable and more efficient, i.e. economically 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 to simply discard. If you familiarize yourself with the design of helicopters that do not have the task of compensating for the reactive moment and have no tail rotor (TsAGI 11-EA, Ka-22 rotorcraft, coaxial and transverse helicopters), you will see that all of them still have a tail boom, on which has a fairly large horizontal and vertical tail unit. Senior Researcher 9.04.86g B.L. Artamonov. Engineer - constructor of the 1st category 9.04.86 V.N. Zhuravlev (today - Doctor of Technical Sciences).    

By the way, the Ka-22 has no power. beams, there is a tail section of the fuselage, on which the tail unit is attached, and at TsAGI 11 -EA, the keel attachment generally begins almost immediately behind the cockpit. Most likely, V.N. Zhuravlev at that time it was unimportant with vision, but at the same time I do not see anything negative if the Ka-27 coaxial helicopter has hv. beam: it does not have an intermediate gearbox, there is no end beam with a tail gearbox and a propeller, so it is many times lighter than xv. beams of the helicopter of the classical scheme and does not burden the helicopter when maneuvering like the Mi-28 or Mi-8, but on the contrary helps it with the help of the tail unit.

Here is a diagram of a rotorcraft, which after processing it professionally surfaced in Eurocopter. (Patent No. 2445236 - High-Speed ​​Hybrid Helicopter ... Priorities: Application Filing: 2008-04-25).

 “... 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 that the President, after the demonstration flights of the Ka-50, did not believe his eyes, but believed the ex's lies. Minister of Defense S. Ivanov and now, instead of the outstanding, the world's best attack helicopter Ka-50 "Black Shark", a mediocre, and besides, a crude Mi-28N, is supplied to protect the State. 

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".

These grief - "hunters" in all competitions occupy the last places, and they continue to arm our Armed Forces, while they should have been removed from service long ago, and our army pilots should have been transferred to reliable and maneuverable Ka-50s; instead of the flying "fortress" Mi-8 "Terminator", the compact, faster and safer Ka-32-10AG will be put into production.

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

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 "!!!
