About Ka-50 attack helicopters:

the development of advanced Ka-50 attack helicopters in 1977, when the fleet of the Soviet Army attack helicopter was in 24s, I made up. " In terms of performance that could challenge the new American AH-64 Apache helicopter fire support, which was developed at that time. Various configurations of the helicopter and examined, as designers try to fight "Kamov create a new leaderMachine. The experience in Vietnam and propulsion helicopter in Afghanistan said on the low vitality of the classic single-rotor because of its vulnerable tail rotor and rotor extends.

The advantages of an aerodynamically balanced coaxial main rotor came to the fore. The helicopter rotor provides easier control in both manual and, above all, auto mode, excellent maneuverability, departure and landing in windy weather. The coaxial rotorsignificantly improve survival in helicopter rotor disk makes the compact and significantly reduced the loss of engine power. View today's Ka-50 helicopters in the world's best for the efficient use of engine power.

Many of us no one can doubt Russia's MiG-29 and world famous acrobatic stunt called the "bell", or Su-27's "Pugachev Cobra", recalls the shock experts and spectators. Ka-50 also has its own aerobatic team, our strength from, any machine canBecause of the "funnel" as perfect as Ka-50. Indeed, the "funnel" is an element of stunt, to ensure the concentration of a helicopter to locate the fire in goal. In addition, the continuous movement of the helicopters in the "funnel" in azimuth and elevation makes the timing very difficult enemy. The Ka-50 can shift the angle to 80 km / h, or back to 90 km / h. It only takes a few seconds in flight to turn back. Ka-50 is the only job in the world, floating can motionless for twelve hours straight! The priorities of the Kamov "Company" far beyond its unparalleled experience in the theory and practice of building coaxial rotor helicopter. In 1965 the company began issuing the rotor blades of glass fiber in their ten years before the rest of the helicopter world. Like the leaves of the fourth generation are now installed in the Ka-50. One of the Ka-50 rotor blades of the last 30 holes caused by blows to the automatic test> Helicopter survival. The boat went on without incident for 80 hours of flight.

The Ka-50 has the power to fight is based mainly on anti-tank guided missiles and cannon fire based. Often, a helicopter attack tanks, enemy is a good goal. Ka-50 is able to respond to this threat with his "Vikhr" supersonic anti-tank missiles, with a maximum range of 10 km. This weapon will reduce the time spent in the area by helicopter in the line of fire, as the sameOver time, the effective range of enemy air defense missiles. The combination of the missile warhead at supersonic speed includes several backups. All of these factors with high precision jam-proof system provides guidance in the undertaking effective combination of different objectives, including hard targets (armor with dynamic up to 900 mm only) and unit targets flying at speeds of up to 800 km per hour, with the same type of ammunition. The rocket is his cover note:Enemy detects the attack only as a success. This weapon is characterized by falling reserves, which are also used to fight to improve his skills. tests have demonstrated the excellent features of the automatic control system of power: the objectives of a small distance defeated far more effective.

The powerful 30 mm gun was by the army and ammunition in connection with the loan fully standardized with BMP-2 infantry mechanized vehicle. The gun is 2A42selectable rate and enables the selective delivery of two boxes of ammunition with explosive sounds of drilling and heavy loads. These increases design efficiency with a pistol than 30 percent into the fire against light armor or air targets. The course of life, which allows the full load of 500 laps continuously fire without intermediate cooling. The BMP-2 and the army attack helicopter gun mount is shown in extreme dust. The gun assembly in Ka-50is rather unusual. To maintain high accuracy together with other remarkable properties, the gravity gun is installed in the center of the helicopter.

This ensures strength requirements and eliminates the need for further reinforcement of the structure. In addition, this factor helps to reduce the recoil effect, the helicopter weight and keep the attention on how the spent round. The electro-hydraulic servo-drive provides the vertical and horizontalMovements of the barrel to keep the line of fire. The 2A42 cannon mount "Kamov" experts in the development and management of avionics systems. The contract for weapons control electronics and integrated avionics system developed was assigned to a specialized firm who have similar systems for MiG and Su-places. The Ka-50 and the crew was so "Vikhr" missiles are guided by a team of designers from the weapon Shipunov AG, corresponding member of Russian Academy of agreementsScience.

Ka-50 armament different versions have been proposed to improve the boat's existing fleet of Army helicopters provide fire and against different targets. load capacity locks Pylon ', the only limitation: the terms Ordnance are attached to four suspensions that can get virtually all systems of air-based weapons. For the full range of ammunition, no changes in the design or algorithm of arms control is required.

L 'Stations of arms can be tilted. Following a deviation of 10 degrees down, masts, to some degree, the suspension of new properties to conventional weapons on them. Fuel tank can count on all the mountains, if necessary.

Group activities for combat helicopters Ka-50 has the necessary equipment and receives data from various systems of educational management. The data received are displayed on the windshield indicator.

To achieve high precisionoperation of air weapon systems, the human operator has been replaced by an automatic control system. The human factor, which are the appropriate emotions and stresses, was eliminated from the most critical part of the system due to the quality of the national defense sector and the experience of "Kamov" experts in the development and operation of avionics won. The contract for weapons control electronics and integrated avionics system has been assigned to a specialized company, thedeveloped similar systems for MiG and Su-places. The Ka-50 team has been reduced to a minimum: It consists of a pilot.

Since the beginning of the helicopter presented improved survival. On the one hand, a compact single-pilot was easier to protect the raft, while the protection should be reliable enough to ensure the only crew member. Unlike its counterpart, "Apache", Ka-50 are the fundamental units are much smaller.complete elimination of the tail rotor, together with its controls and means of transmission that give the tail boom can be sustained without serious consequences. Measures to improve the survival craft and REW ensured the successful resolution of at least 26 problems. These include the continuous operation of the drive rotor, despite a damaged oil system that supports emergency exits, fire extinguishers and many other large.

Composite materials areThirty-five percent of the helicopter structure. They are not simply to reduce the weight of the craft. When hit by bullets or grenades, do not produce secondary effects composite (chips, drawings) are characteristic of a metal surface.

Particular attention was to protect the flight compartment and fuel system. The Ka-50 pilot in a cockpit is fully armored and shielded sits with a weight of just over 300 kg. Several experiments with different protective materialsdemonstrated high reliability and combat characteristics of the combination of steel tanks. The case is part of the hull of the basic structure in more than force. Because of the increased resistance on the outer shell of such weapons, the pilot of several direct hits from 20mm shells are protected. The cockpit design and layout of the changes affecting 10-15% of the inner compartment on impact with the ground. No component can penetrate into the helicopter cockpit whenassociated parts are destroyed.

The new helicopter landing gear and fuselage are designed to absorb the impact of congestion on the ground. The scheme of power supply system prevents any possibility of fire following a hard landing craft. If one of the two engines are damaged, the Ka-50, continued flight on one engine operating system. The oscillating rotor control rod plate to keep working, even if they were shot two large caliber machine gun holes.

The emergency fundingEscape system deserve particular attention. And 'the world's first practical helicopter pilot ejection system. The system works reliably in every critical situation. The only places helicopter pilot concept ensures maximum survival. The K-37 course at the company "Zvezda" by the team of head designed GI Severin, Corresponding Member of Russian Academy of Sciences allows pilot emissions at all altitudes and speeds, including zero. The pilot can also help you out of troublewithout expectoration. A series of consecutive operations are performed on board the vehicle, as the system worked. This includes the emptying of the main rotor blade through the opening panel of the cockpit and the operation was followed by the engine case of expulsion. The old system is the most convenient for a single seater helicopter due to lack of time available during the course of at least altitude.

The problem of time and effort with the ground staff for preparing the vehicle forCampaign has been successful for the Ka-50 fixed. When the helicopter is armed to the ground, built to provide electric hoists for easy adjustment of the arms with a weight of up to 500 kg. The supersonic missiles are loaded as part of the process of accumulation is belted ammunition boxes in a simplified and mechanized. Provision of equipment by helicopter, for operation of several specialists at once. The unit is easily accessible because of the large capitalizationAperture. The Ka-50 has a special Teflon grease hinges in all fields of the mechanical system used.

Enjoy a life of at least ten times longer than normal storage conditions. The Army Ka-50 is to be located far from unprepared for the service expanded from large bases of plaster airports.

Special Forces and foreign experts, Ka-50 is not just another good job to fight According to Air: It represents a new trend in construction and army helicoptersAviation helicopter tactics designed first. "To" neutralize the U.S. AH-64A Apache "attack" Ka-50 has outperformed its competition in every aspect. Now foreign companies, 50 contracts for the attack helicopters customer must meet the requirements of a machine to provide at least as good as Kamov.
