Top military helicopters of the world
Mi-26 is designed Mil as a multipurpose heavy transport helicopter. There are 16 versions of the machine, both military and civil purposes. "In the civilian world," Mi-26 puts out fires, evacuating patients involved in rescue operations, carries on the external load multi-ton loads on the construction, as well as the passengers - up to 63 people. As the military is involved in desantirovanii solves transportation problems. There ASW, radio engineering and control tower versions.
The Mi-26 has a single-rotor scheme with the tail rotor. Diameter 8 lopostnogo rotor - 32 m, the steering - 7, 6 m. Two engines of 11,400 hp lifted into the air 56-ton machine with a payload of 20 tons.
The maximum speed - 295 km / h cruising - 265 km / h
Service ceiling - 6500 m
Range - 800 km.
The helicopter is equipped with modern navigation aids, including the autopilot system and damping external load.
Mi-26 carries 80 paratroopers in full gear, 60 stretchers with the wounded, 20 tons of cargo in the cab, or 18, 5 tons on the suspension.
Crew - 5 people.
Issued 310 machines.
In 1982 he made the first flight in the Kamov design bureau developed attack helicopter Ka-50 "Black Shark". It has fuselage and empennage of the aircraft type. Equipped with two coaxial rotors.
The machine is unique in a number of design features, the first time it used, which allowed to achieve excellent flight and combat characteristics. "Black Shark" makes a loop, and the maneuver "funnel" - moving around the target with a change in altitude at a speed of 180 km / h. Through the use of highly automated piloting and firing Ka-50 is operated by a single pilot. On tests "Black Shark" still hangs in the air for 12 hours without a significant participation in the pilot stabilization.
There is a low-altitude flight mode with automatic tracking of the terrain. TV and infrared sensors allow you to define target located at a distance of 20 km. The Ka-50 is used by a wide range of weapon systems - from the 30-mm gun, designed for BMP-2, before the missiles of various types - missile, antitank, incendiary and high-explosive bombs.
Maximum take-off weight - 10800 kg, the weight of armament - 3000 kg, of which the pylons - 2000 kg.
The maximum speed - 315 km / h speed in a dive - 390 km / h
Static ceiling - 4300 m, the dynamic ceiling - 5700 m
Range - 545 km.
In 1997, the air rose Ka-52 "Alligator" which was based on the "Black Shark". The differences mainly consist in the use of new indicators based on liquid crystal panels. Also, there was an additional chair for the second catapult pilot. All performance characteristics are the same.
Rotorcraft of Lockheed AH-56 Cheyenne was able to take to the air in 1972. It was an attack helicopter for the US Air Force to reach speeds of 407 km / h. However, in a series of car did not go due to the tightening of public procurement and deadlines arising on this basis the financial turmoil.
But the car is worth mentioning if only because no one more than the high-speed military helicopter has not yet created. It was manufactured 10 prototypes Cheyenne.
And practical ceiling made in this design, is also impressive - 7925 m.
Range - 1400 km
Take-off weight - 7700 kg
The crew of two people was protected by armor plates.
Unique Rifle station allowed to control 210 degrees surrounding area. It included 12 periscopes for laying, anti-tank system, a laser range finder and a night vision system.
Joint development by Boeing and Sikorsky - reconnaissance and attack helicopter RAH-66 Comanche - cost $ 2, 8 billion., While the production of cars in 1300 was estimated at $ 36 billion. In the sky prototype rose in 1996. It was the most expensive in the history of the helicopter project.
When creating this machine the most attention was paid to its low detectability in the radar, infrared and optical regions of the spectrum, as well as reduce the level of noise generated by the engine and propeller. "Kamancha" built on stealth technology with the use of composite materials. The problem of infrared "exposure" was solved by mixing the hot gases emitted from the cold air outboard.
As a result, the parameter "effective dissipation area" from "kamancha" 360 times better than the legendary "Apache", and 28 times better than most undetectable until it arrives, "the scout» Bell OH-58 Kiowa. By acoustic performance RAH-66 is also a champion. With regard to the visual masking, the in-flight helicopter hides inside all that can be hidden, including gun. In addition, the machine is very "thin" - the width of the fuselage is 2 meters.
Maximum take-off weight - 7900 kg payload mass - 2300 kg
The maximum speed - 324 km / h
Range - 280 km
The work of all helicopter systems "knows" the powerful on-board computer.
However, despite the money spent and the achievement of excellent results, the machine has not launched into serial production. One reason is that it was decided to use drones for intelligence purposes. At the beginning of the century due to the development of digital technology they have purchased a high tactical and technical indicators.
Multi-purpose Mi-8 helicopter, developed in Mil, took to the air in 1961. Not only was it the most massive helicopter for military and civilian use (so far produced more than 13 thousand. Machines), but also the most versatile, and the oldest of the mass-produced.
Helicopters operated in more than 80 countries. To date Mil has created more than 60 different versions of the machine, which thanks to its ruggedness, ease of maintenance and good performance data using almost any all spheres of human activity, where transport problems are solved. (To this family of machines owned by helicopters to the base number as the Mi-8 and Mi-171 and Mi-172).
As for the use of Mi-8 in the army, there is a transport option, stroke, assault, amphibious, minoukladchik helicopter amphibious, tanker, reconnaissance, radiation and chemical reconnaissance, airborne command post, armored air hospital, the director of radio interference.
The number of fighters, which takes on board the car - from 18 to 32
Maximum take-off weight - 13000 kg
Engine power - from 2h1500 hp to 2h2000 hp
The maximum speed - 250 km / h
Dynamic ceiling - from 4500 m to 6000 m
Range - from 480 km to 710 km.
