How was he did there - helicopter from the past
February 15 2017, at AEX.RU "This year, plans to open development activities (R & D) to develop the project of the modernized Mi-26T2V Terms of Reference of the Ministry of Defence has already been received.", - Said the source.
According to him, it is expected that the ongoing R & D will not be funded by the Ministry of Defence, and the holding company "Russian Helicopters" and compensation costs by the selling price of the helicopters when they are followed by the purchase of air and space forces (VKS).
"End state joint tests of Mi-26T2V planned in the fourth quarter of the year 2018" - Said the source.
According to him, Mi-26T2V will be capable of taking off and landing from unprepared sites. It will be equipped with an autopilot and a new avionics allowing to operate at any time of the day.
"Also on the Mi-26T2V establish a modernized digital complex communications and onboard defense system for enhancing the survival of the helicopter. The helicopter is able to perform combat tasks in any, even the most adverse climatic and weather conditions, day and night" - The spokesman said. AEX.RU
"The more we delve further into the forest, the more increases the energy resources of the forest."
** According to a peasant: "Next to the forest - more wood."
"With the subsequent reimbursement of costs by the selling price of helicopters at their subsequent purchase of aerospace forces."
** According to a peasant, "to raise the price!"
"According to him, Mi-26T2V will be capable of taking off and landing from unprepared sites."
** Helicopter and coined to fly "from unprepared sites," this is a case where "size does not matter." It is strange that the holding heads before it was unknown and "allowed" to operate with the selection of sites with air only through 30-odd years of its operation.
And how he upgraded Mil helicopter Mi-6?
He set him on the wings, increasing cruising speed to 50k / h. Than increased productivity by helicopter 25%.
As a modernized Ka-32 in the "Kamov"?
As a helicopter from the past has a very high drag, so S.V.Miheev designed a new modern fuselage commensurate with the volume of the fuselage Mi-8, but with engines, gearbox and rotors on Ka-32Ie the most expensive units left serial. Due to the smaller frontal resistance of the helicopter speed performance will be significantly increased, and the interior - much more comfortable.
As a modernized IL-76?
In the first series he was carrying 28t. cargo, and the last modifications - 52t. cargo.
And in this regard, it upgraded Mi-26?
Yes way! He has to date only two unquestionable superiority:
1. The biggest.
Useful loading speed and the same as that 35let ago. Bólshego and will not work, because in this helicopter from the classical scheme taken everything to the maximum.
I have no doubt that whether today Mil General Designer is using the unique capabilities of the engines and the rotor Mi-26He would have designed it on the basis of something new. For example, a helicopter similar in-12, but with a modern edge. And would such a helicopter is much more productive and profitable Mi-26. In the meantime, there is no novelty: as he was, he is - a helicopter from the past!
Remembering The 12-lateral scheme, is not superfluous to recall a review on this Sergei Sikorsky helicopter after watching his flight at Le Bourget: "Before the engineering achievement, as is the helicopter in-12, can only take my hat ... This helicopter is the only its kind and will be used to perform unique operations. I am referring to the expedition in the Arctic regions or search for oil deposits. The helicopter will replace the railway, where is still untouched by human hands. " ( "Science and Life", №8, 1998)
And ahead of expected modernized Mi-12M in 2raza Hoisting Mi-26 and not expensive. Do not go away Mil prematurely from life, and now giant Mi-12M It would bring enormous benefits to our state in the national economy and, in particular - in the reconstruction of airfields in the Arctic.
General Designer MN Tishchenko, replacing Mil, remained faithful to the classical scheme and designed by its more compact Mi-26 capacity up to 20t. To give it a "green light", with its "path" have been removed at the demand while Mi-6; to the same and in-12.
Mi-26 compared to MI-6 transporting cargo twice as much, with the cost to 4raza more expensive, but its general designers MVZ upgrade! However, for some reason to increase the cost rather than performance.
Speaking of performance. When comparing the helicopter classical scheme with other schemes for the same engines, the difference in favor of others simply striking. For example, rotorcraft Ka-22 and Mi-6 helicopter - each with two engines D-25V but rotorcraft 1,4t turned on. easier Mi-6. This means that the rotorcraft to transporting payload almost 1,5t. more because they have the same maximum takeoff weight - 42,5t.
In Ka-22 trapezoidal blades, cruising speed = 270k / h.
"For in-ta Mi-6 trapezoidal blades with normal flight weight (40,5T) and less than the cruising speed on the instrument is set in the following ranges:
Height, m. Speed, km / hour.
2000 - 3000 200-190 »...
( "Practical Aerodynamics of the helicopter Mi-6» MS Yatsunovich. 1969g).
The difference in favor of the cruising speed rotorcraft impressionable, ie taking into account the duty bólshey productivity Ka-22 would be higher than the Mi-6 least 40%.
Now let's compare modern helicopters coaxial Ka-32-10AG and classic Mi-171A2 with the same engines VC-2500. Carrying capacity in Ka-32-10AG is 5,5t, while Mi-171A2 -.. 4t, or 1,5t. less.
In general, the Ka-32-10AG superior Mi-171AG at times, but in a series launched the Mi-171A2 helicopter with obviously worse characteristics.
Decrypts the word "several times."
Mi-171A2 inferior helicopter Ka-32-10AG:
2. According rates.
3. According maneuverability.
4. At the tail rotor will stop by themselves.
Failure of the tail rotor in flight, a rare case - a catastrophe.
In combat conditions xB. bar is a very vulnerable place and easily interrupted from a heavy machine gun, and if not the beam, control xB. screw, but in any case, to put it mildly - very hard landing! The same result, and after the missile gap xB area. screw.
It is very difficult at the landing, especially when loading commandos wounded from the battlefield - not to catch the tail rotor for anything when maneuvering in the forest, the mountains, near the buildings. For example, in Abkhazia during the Georgian-Ossetian war, Abkhaz soldiers were forced to jump out of the landing of Mi-8 from meter height on the rocks, as the landing of the helicopter threatened to catch the xB. screw for a boulder, where there is visible and invisible, probably in front of and behind the invisible, ie, under the tail rotor!
"At Ka-50 damage to the tail does not lead to catastrophic consequences, as fully retained control unit using the aerodynamic forces and moments on the co-axial screws. On the flight speeds of up to 200 km / h, the helicopter can continue to fly even if you remove the rudder, which is confirmed by flight tests. During tests it conducted an unprecedented experiment - shooting in the tail section of the keel-80 and horizontal tail in flight. The helicopter broke down and it demonstrated sufficient stability and control, and the ability to land normally. " (Website of the Russian military equipment. Multi-purpose attack helicopter Ka-50).
