"Unbreakable" Mi-24!

"Unkillable" Mi-24!

 

On March 9, the article “Kamov vs. Mile ...", Which describes the advantages of the Ka-50 attack helicopter against the Mi-28N.

And already 23 March counterweight to an article in the media, glorifying Mi-24:

"No wet places left: Russian Mi-24 staged militants in Syria with a" death carousel " ("At gunpoint").

It would not be worthwhile to focus on this article, but the baron Munchausen would envy the separate "vital" moments of Mi-24 from the article:

"Mi-24 turned out to be so indestructible that legends about it go far beyond Russia. For example, at the beginning of 2000, one Mi-24 from the UN fleet, flying over the Atlantic Ocean, lost altitude and dived into the water. For any other helicopter, this event would end in a catastrophe, but not for Mi-24. The helicopter emerged from the water and flew farther as if nothing had happened. For this maneuver the board was nicknamed "Calypso" and a drawing in the form of a helicopter-submarine with a periscope ".

COOL!!!

But for another excerpt: "Installed on Mi-24 gas turbine engines with the power of 2000 horsepower allow the car to develop speed of 335 km / h, and in case of failure of one of the engines, the helicopter can safely return to the base on the second" - the author will have to be educated.

The speed is correct, but the fact that Mi-24 flies easily on one engine is very doubtful, because in reality it is obviously not enough for two of them:

"The high-speed characteristics of the Mi-24 were achieved at the cost of the load on the main rotor, one and a half times larger than the G-8. In the daily extreme conditions (heat, high mountains, increased dustiness) this had a significant impact on management. Moreover, the habitual piloting skills were often even harmful and could lead to an accident. On takeoff and landing with a heavy screw, a sharp movement of the handle caused a drawdown, the car was trying to hold the "step-gas" dacha, the "weak" engines did not have enough throttle response, and the helicopter fell to the ground. At low speeds on the "hill" or near the ground, Mi-24 began to behave unusually. Manageability at the rate was not enough, the reactive torque of the main rotor pulled the car into a spontaneous left turn and could be dumped in a helicopter spin. With energetic maneuvers with overloading at high speeds and angles of attack due to a stall from the blades, Mi-24 picked up his nose, switching to "pick up" - kabirirovanie with disobeying control, and then fell down sharply. The case more than once ended in a rough landing on the wing tips and blocks. Avoid "pick-up" could be strict compliance with restrictions, but in battle, "lower and lower" was not necessary. In the "pick up" and with an energetic withdrawal from the dive, there were blows of blades on the tail boom. So, in August 1980 year after the attack of the caravan of the "twenty-quarters" of the squadron commander Kozovoy and his deputy, Alatortsev returned to Faizabad with tails pointed in blades. This incident had tragic consequences: after going to the control overflight after the repair, Mr. Kozovoy fell under the fire of DShK, the helmsman with the bladed lobe went panting, the damaged tail boom collapsed, and the uncontrolled car collapsed, burying the entire crew. It lost the Hero of the Soviet Union V.Gainutdinov, - the comass from the "Eight", who took the place of the operator in the car of his comrade in the school "... (The scorched sky of Afgan. Combat aviation in the Afghan war Markovsky Viktor Yurievich).

By the way, in addition to the two lost Mi-28 helicopters and one Mi-24 in Syria due to their unreliability, the Mi-35 was also shot down by a missile: the video clearly shows its rupture in the area of ​​the tail rotor, the propeller collapsed and the helicopter fell to the ground in an unguided mode!

In an experimental flight on Ka-50, the tail beam was shot: the helicopter flew to the airfield at a speed of up to 200km / hour and safely landed! This is another and very valuable advantage for the combat helicopter, because the militants are always firing from behind.

In this case, pilots with Ka-50 / 52 would have 2 survival options:

  • Fly without a tail unit to the base and make a landing.
  • Catapult and stay alive! There, the second helicopter was also barraging, which is clearly visible on the video.

According to the TV host of the program "Time will show" A. Scheinin - every action has its own meaning and purpose, or according to Kozma Prutkov: "Look at the root"!

You can look and "at the root", good with the Internet you can all:

"The leading Soviet helicopter company" Mil "was under the control of the American company Sikorsky, in whose interests the equipping of the Russian Armed Forces with modern models was by no means included"... ("Rossiyskaya Gazeta" - Federal issue No. 3613 dated October 26, 2004).

And I thought at first that they only have commercial interests that take precedence over state ones, it turns out that we need to take it higher: for the role of the ram in moving to the Mi-28 series from our "sworn friends", S.Sikorsky was sent to them and our Army was left without the best in the world Ka-50, and then without Ka-32-10AG, which "customers" did not "find". But fly our pilots on helicopters Ka-32-10AG and "evil rock" would bypass the side:

"Evil rock pursues the Russian army: Mi-8 crashed.

In the Itum-Kalinsky district of the Chechen Republic, a Russian Mi-8 helicopter crashed.

A Mi-8 helicopter crashed in Chechnya due to a sharp gust of wind, - wrote the head of the republic Ramzan Kadyrov in his telegram channel. According to him, the aircraft was supposed to deliver border guards to the outpost in the Itum-Kalinsky region. Seven people stayed inside. The aircraft fell into the abyss from a height of 150 meters. 7 March 2018 ".                                   

 

"The details of the helicopter crash became known ...

According to the latest data, before the board fell, it strongly spun. As a result, people in the salon began to scatter on different sides. At that time, the pilots of the MI-8 helicopter had completely lost control, unable to keep its aircraft in the air " ("InfoRector").

Very, very sad! My condolences!

 

Less than a month passed: "In Belarus, I crashed in an apple garden ... 23.03.2018

Combat helicopter Mi-24 Belarus collapsed in front of a married couple who happened to be by chance. When they saw a noisy helicopter in the sky, they decided to shoot it on the phone's video camera. Thanks to them, the whole process of falling was accessible to the investigation and the whole world. The frames clearly show that the helicopter at one point at a low altitude swirled, and then collapsed to the ground.

The reason for such a strange behavior of the helicopter, according to experts, may be technical problems with the tail, or pilots' error. "

Here the landing is softer and everything is in order with the pilots, which means that the conclusions of the IAC will be objective, but in any case, the same tail rotor is directly related to this fall. He was also the culprit in the last 3 disasters in Syria, so it is not rock that should be considered "evil", but the tail rotor, which should have been abandoned long ago, and the pilots should have been transferred to the Ka-50/52, and the Ka-32. -10AG.

By the way, Mi-8 from the side wind fall not only in the mountains, but also on level ground.

KRASNOYARSK, 25 February. / TASS /. The reason for the hard landing of the Mi-8 helicopter at the Arctic cape in the Krasnoyarsk Territory, according to preliminary data, was a rush of a side wind. This was reported on Sunday by the press service of the Western-Siberian Investigation Department on Transport of the Investigative Committee of the Russian Federation.

"According to preliminary information, at the time of landing due to a lateral gust of wind the aircraft tilted and fell on its side," the agency said. After a hard landing, a check is made.

"For a helicopter with a coaxial scheme, it does not matter which side the wind blows when taking off or approaching the landing" (Colonel AV Rudykh The word about the "Black Shark": 20 June 2006).

 

The aforementioned helicopter fall suggests that the Minister of Defense S.K. Shoigu should have advisers not only on fighters, but also on helicopters, and on helicopters there should be an adviser from purebred helicopter pilots, such as an army test pilot Colonel Alexander Rudykh, who flew in the combat conditions of Chechnya both on the Mi-24 and Ka-50, i.e. who knows the price of these helicopters not by hearsay, like ex. Air Force Commander V. Mikhailov or VKS Colonel-General V. Bondarev, who, being the VKS Commander-in-Chief, "sang praises" to the Mi-28N helicopter, but when he became a senator realized that the Mi-28N was a lethal helicopter.

But the fact that our helicopter pilots are forced to fly on such an imperfect technique is not a small fault and the MO. Our military servicemen are being killed by Mi helicopters, and the Defense Ministry continues to conclude contracts for these helicopters, which are clearly unsuitable for modern warfare, when we have more advanced and ready-to-mass Ka-50 / 52 and Ka-32-10AG!

Designers of the cost center regularly allocated finances in huge amounts for NIRs, therefore, they have to work out this money not in reports but in iron! For example, we still do not have a replacement for the Mi-6 helicopter with the 10-12 tonnage. We began to master the Arctic on the dorogus Mi-26, where the LTX remained the same, but the cost of the flying hour increased more than in 2. At all times and all KB in the mass production of aircraft technology, its value fell, but the designers of the cost center - strictly the opposite !?

Helicopters with increased flight safety and more comfortable ones should be designed to operate in the Arctic and Arctic regions. Today I see a transverse helicopter with such a helicopter, and even with 4 engines of the B-12 type, i.e. cost center designers today have the opportunity to build such a helicopter based on the Mi-171A2. The customer of such a helicopter should be M.O. and moreover, in the contract, strictly limit the cost center designers in time, so that they would not build it for decades, like the Mi-38, but fit into the time allotted to them. In case of failure to meet the deadline - a PENALTY, but such that it was not necessary for them to fail the plan in the future. In this case, the main screws, motors and main gearboxes are serial, hence the construction time should be reduced to a minimum.

Mi-8 built a helicopter from the ground up: "The development of a prospective medium-purpose multipurpose helicopter under the designation B-8, designed to replace the model of the Mi-4 helicopter, began in the Mil Design Bureau in the second half of the 50-ies. The first prototype B-8 took off in the air 9 July 1961 year, it had one turboprop engine AI-24; the second prototype of the B-8 - 17 September 1962, he already had two turboshafts TV2-117, which were already installed on the serial machines "(Wikipedia).

In-12: "Design began in 1963 year. The first flight was made by the helicopter 10 July 1968 (test pilot VP Koloshenko) " (Wikipedia).

Today's cost center designers have support systems ready, a helicopter circuit and powerful computers are ready, they were regularly allocated billions of dollars of money. Or maybe they have an even more modern helicopter scheme? Indeed, in comparison with the Mi-26, it should be economical, cheap, with a large percentage of useful load! And then they GOOD LUCK!

 

Vitalii Belyaev specifically for Avia.pro

In 1980, I flew to Mi-24 in Afgan. For three months came home three times on one engine. We sat down on the plane.

Arseny:
1. On reliability, maintainability (even in the most unfavorable conditions), endurance (including overload and combat damage) Mi-8 and his brother Mi-24
- absolute leaders.

*** Arseny, I must disappoint you, just for two months this year:
7 March in Chechnya helicopter Mi-8 one of the special services fell in the gorge Hangihoy in Itum-Kalinsky district. According to preliminary data, at least five people were killed out of nine on board. The puff of wind blew.
24 February helicopter Mi-8 made a hard landing at the cape of the Arctic Islands Komsomolets archipelago Northern Earth. During the landing, due to a lateral gust of wind, the helicopter tilted and fell to the side. On board were four crew members and two passengers. Injured one of the passengers.
21 February, the Mi-8T helicopter crashed into a tree while taking off from the Pacha landing site in the Lovozero district of the Murmansk region. The helicopter performed a social flight on the route Sosnovka - Pacha - Lovozero. On board there were eight passengers, one person was injured.
12 February 42 kilometers from the village of Aleksandrovskoye, Alexandrovsky district, Tomsk region, an emergency landing Mi-8 helicopter made a medical flight from the weather station Prokhorkino to the city of Strezhevoy. The second pilot and the helicopter technician were killed. Another pilot, as well as three passengers, including a policeman, received various injuries (RIA Novosti).
And today Mi-8 fell in Khabarovsk, to the great regret - with the death of people. The helicopter carried out a training flight, so there was an experienced pilot-instructor, so the crew's error is too unlikely.

***And further. Ka-50 was initially produced with semi-rigid blades, and on the "Mi" such blades are just entering the series, as they are called: with elastomeric bearings.

About the alleged influence of Sikorsky: What is in the article was invented from somewhere. But, in fact, the influence of Sikorsky was! And in this form. This is an interesting and instructive story. Kamovites blush here. But you need to know this, because this shows the effective preparation and operation of the entire American system. Listen. The United States then declared the development of a new attacking attack helicopter a priority. And it was used for intelligence from all sources, which is being done by a SOOS helicopter, with ONE crew member, and the role of the co-pilot will be assigned to the onboard electronics - avionics complex. S.V. Mikheev and KB "Kamov" in the development of their machine went the same way, joyfully (because it was N.I. Kamov and his design bureau who were faithful devotees of the coaxial scheme, and after the death of Nikolai Ilyich they lived exploiting those developments) proving to the top leadership of the country that "you see, even the Americans decided to use this excellent scheme! (It should be noted that on the Sikorskoye the coaxial scheme was used differently, with rigid screws (!), i.e. clashing, due to which on the hinge screws, when the blades make a large swinging movement up and down, (towards the rotating propellers on one side, the propeller blades approach, and on the other, move away) the screws have to be far apart in height, they are almost not threatened.

And the Milevtsy, by the way, are one of the first founders of the concept of a combat helicopter, and a very well thought-out and successful one (Mi-24 and Bell "Cobra" (USA), went the way they considered correct:
Single-screw scheme, the crew - tandem - 2 man one for and above the other. Excellent overall visibility with a small glazing area, which all could be made armored. They abandoned the retractable landing gear, which gave a gain in the speed of the flight, but made a non-retractable landing gear capable of extinguishing the energy of the impact when it fell. (instead of an airplane catapult and firing blades on Ka-50, the Milevtsy investigated this topic and abandoned it). The concept was chosen when the pilots must remain in the cockpit and the car must save them.
And then - Tadammm! The most interesting thing: After all this official public information and "leaks", a real American car rolls out: a combat two-seater single-rotor helicopter of a classic scheme with a pilot and a gunner sitting in tandem behind and above each other!
"Apache".
As I understand it, Americans successfully and effectively use this scheme to launch a false and possibly dead end track.
After this story, already in my air presence I watched the same move.
The priority military program, proclaimed by the United States was a promising helicopter - a penetrator (from penetrate, penetrate). Smaller than the Apache, not armored, but the efficiency had to be achieved with smaller dimensions, less visibility on radars and on the generated heat, the so-called. stealth technology, invisibility. We closely followed the Comanche project, the technical side, the technologies, the program budget, the TTX, the progressive control systems, the possible tactics of using and countering it ... and then suddenly (!) The Comanche program disappears and drone drones roll out .. .

Well, the author is clearly a journalist, and far from the topic?

1. On reliability, maintainability (even in the most unfavorable conditions), endurance (including overload and combat damage) Mi-8 and his brother Mi-24
- absolute leaders.
2. The coaxial design is really good because it is dynamically "balanced" and has no tail rotor. This helps keep the hover level and avoids getting hit by the tail rotor where it is cramped (great crane, and handy on ships). But: The carrier system with two rotors, a complex transmission, and two swash plates is also a more convenient target, more vulnerable to hit by the same damaging agent than the compact but massive hub and HB of the classic helicopter scheme.
3. The steering screw ensures the efficiency of the track control (compensating, exceeding or yielding to the reactive torque from the main rotor, the shoulder is large, the moment is large).
On a coaxial helicopter, directional control is carried out by changing the distribution of the load between the upper and lower rotors (the same, lends itself to the left or to the right), but to ensure a sharp effective maneuver, it was necessary to distribute something. Maximum thrust is available in hover mode and at high speeds. But when descending at low speeds, we find ourselves in the lower part of the "spoon" on the graph of power (thrust HB) versus flight speed. And there is not much to distribute here. And the track control has low efficiency. That is, for even a small turn, you have to press the pedals for a longer stroke, and pray that it would be enough ...
4. On Ka screws are articulated, and the problem of shredding the blades of the upper and lower propeller during a sharp maneuver is a serious limitation in control. This is technically accompanied by coaxial construction. Black shark killed so in my memory two experienced test pilots who knew everything in the helicopter world, and this car. Screeching. And the impact of HB on the tail beam on the classical scheme occurs only for completely out-of-the-way situations.
5. The coaxial helicopter issues itself, because it is very noisy (what we hear from the helicopter is basically the cotton flow from the blade over the tail beam.And the Soosnik claps even at the passage of each blade over the blade with folding speeds, so that the noise from it is much louder), and the high-pitched carrier the system above the helicopter does not help very much to hide behind shelters at low altitude.

Yuri, since I do not grovel before the United States, then continue this responsible work without me. Vital.

Vital, would deliver himself a pizza or burgers, what the hell was in the helicopter ...

Each helicopter has its own purpose. Milev helicopters are strike assault helicopters, KAMO - are effective for special tasks. They compare, it's like comparing the Rooks, for example, Dry 27-mi. I repeat, each of these helicopters has its own function, that's why the regiments are equipped from squadrons that operate different types of helicopters.

Very correct conclusion. You need to invest money in the most reliable and effective military equipment. Pilots need to be covered with modern, light bullet-proof material. Technicians should be selected test pilots and experienced combat pilots, not cabinet experts.

Afftor on complementary foods at Kamov's? The writer, apparently, does not know that only those types of armed forces that are actually fighting are shot down in a war. And I would also advise the afftor not to dwell on the stories of Colonel Rudykh, but to ask other participants and witnesses of the "valiant battles of KA-50" in the Chechen Republic in 2000: profanation for the money of the Kamov Design Bureau, carried out by the flight crew of the AA PPP in Torzhok. Good guys from Torzhok even teach Baba Yaga's broom to fight for money. True, on the cover (like the Ka-50 in the Chechen Republic) there will still be a couple of "well, very bad" crooks and a Mi-8 PSO to save the brave Hollywood men from Torzhok ...
PS: Everything that I wrote about, I watched personally and with the characters of the film about the shark in Chechnya is not familiar on the Internet. Something like this...

A crocodile can also be indestructible. Easily killed by his crew. Even their machine guns

You will be the first who with a hand-held machine gun will come out against a pair of slabs in a stretched BP and overwhelm him. Skovko skok such brave is still buried under the poles with a red rag on the end.

Adviser on helicopters from Shoigu is-Lieutenant-General Zakirov R.Sh. is not the last person in AA.

On coaxial machines, the number of accidents and accidents is not less, by the ratio of the number of cars produced. We must remember which helicopter Vorobyov died, and Mi-24 really flies at a speed of 335 km / h and can fly on the same engine under certain conditions. A bad dancer knows everything, what's stopping, what's on the Milevsky machines, what's on the Kamovsky.

"The high speed characteristics of the Mi-24 were achieved at a price" - (not at a price, but due to) the use of a low aspect ratio wing, which made it possible to unload the main rotor, thereby reducing the required angles of attack of the blades for this flight mode, which reduced the aerodynamic drag of the blades, allowed increase top speed and ceiling. The same technique was used on the Mi-6 and the American Cobra for example.

Major Kozovoy was not shot down, but died when the helicopter overflown. When he began to show the figures of aerobatics to Gainutdinov, he hit himself on the tail boom.
