Ka-29. A photo. History. Characteristics.

 

Since 70-x and 80-ies, there was a need to increase military capabilities for the Soviet Navy. In 1973, Kamov OKB received a request to create a new helicopter of wide application. Deputy Designer S. Fomin was appointed responsible for the new project. In documents, this helicopter was called "the 502 product", and in the troops - Ka-29. The specimen was created on the basis of the anti-submarine Ka-27. To help Fomin appointed the lead designer G. Danilochkin and S. Mikheyev - OKB designer. The first flight was carried out in 1976 year in July by test pilot E. Laryushin. Serial production began at the aviation plant in Kumertau.

Ka-29 is calculated on the full support of airborne troops, it can also destroy ground and surface targets. In addition, an important function of the helicopter itself is considered an opportunity to carry a live military force or special cargo from land to the ships and vice versa. The first BBC, available to the Ka-29 (up to four helicopters) were "Mitrofan Moskalenko," "Alexander Nikolaev" and "Ivan Rogov". At the stern and the bow were constructed helipads.

In Ka-27 were taken the main part of the fuselage, gearbox, rotor system, control system, landing gear, fuel supply systems and energy, as well as navigation and flight systems. A copy of the improved radio set "Eucalyptus" and the ARC-UD.

The helicopter crew consists of two people: a pilot and a navigator-operator. They are placed next to each other in the cockpit, exceeding the dimensions of the base unit by 500 mm and the presence of armor protection from the caliber 7,62 mm. Also, the armored plates are mounted on the hoods of the pump-regulators of the TVZ-117VMA engines. The whole armor pulls on 350 kg of total weight. Tanks with fuel are filled with polyurethane foam, which excludes the possibility of an explosion, and in the walls - a specialized self-tightening rubber, which protects the tanks from leakage (with lumbago). The engine's exhaust-exhaust mechanisms are able to protect the helicopter from heat rockets.

Armed helicopter controls system VCS-252, on the dash-mounted TSA 17VK (scope for the application of the NAR, container weapons and guns). The department co-driver-operator is present SNPs used for detection purposes and the use of anti-tank. The pilot is responsible for the control of the helicopter and actions fixed types of weapons, and the navigator has been vertoletovozhdeniem, guided missiles and mobile machine gun.

Among the many ways to use the Ka-29 are two main: transport and combat. Transport option includes chetyrehstvolny gun (caliber 7,62 mm), which is hidden in a special embrasure. Equipped with a cabin carries up to 16 paratroopers in full armor, or four stretchers with the wounded, or seven seater. Also inside you can carry small loads of up to 2000 kg, and on the external sling loads are increased twice (cargo size is not important). Among other things, in some versions present a rescue winch.

Ka-29

Battle variant Ka-29 designed to conduct combat operations, maneuvers and perform complex tasks. Support for infantry and heavy equipment at the expense of guided and unguided missiles, gunnery and bombing armament. Container type of weapons mounted on the outer blanks holders (4 pieces) truss. Location symmetrical. On the left side is set 2A42 gun (caliber 30 mm).

Since the principal place of helicopter based on the ship, its size coaxial have been minimized, and the rotor blades are designed for the folding mechanism. There is a specially designed chassis for landing on the deck of a rocking ship, folded HB blades meet the dimensions of the airframe.

It Kamov Design Bureau in the Soviet Union established the first helicopter to the presence of weapons against both marine and terrestrial against opponents. According TTZ firepower of the helicopter had to meet the combat Mi-24V. As a result of the work of Ka-29 in many ways ahead of the opponent. For example, elementary 2A42 gun mounted on a helicopter, showed themselves more effectively against large-caliber machine gun YAKB-12.7 Mi-24V.

High accuracy with shots of weapons provided by the simplified piloting technique and the low level of vibration. It coaxial rotor helicopter aviation platform has enabled the placement and use of a laser rangefinder with the sight axis.

Mostly Ka-Mi exceeds 29-24, which is not surprising, since the coaxial scheme pulls the whole power of the engine to work rotor, which creates a lifting force. Simultaneously with this process, the reactive moments are mutually balanced. The result is that the potential costs to compensate for reactive power torque is completely absent. But on the single-rotor machine the proportion of engine power goes to the tail rotor drive. Power costs - 12%. At Mi-24 they are not accompanied by the creation of the thrust of the main rotor. Efficiency Ka-29 25% to more.

Also coaxial scheme provides low vibration levels. This is due to the summation of the oscillation of the lower and upper screws. Maximum amplitude of vibration coincides with the minimum of one another.

Increased accuracy on the Ka-29 is provided in this way: the movement of the control handle results in the tilt of the swashplate (s), which are interconnected by the thrust, and the constant change in the setting of the angles of the blades. The result is a common vector of the whole aerodynamic forces of both screws, which deviates in the desired direction and by the desired value. The reactive moments of the screws are completely balanced, and the projections of forces on the lower and upper screws are the same in magnitude. Aerodynamic symmetry of the coaxial scheme is ensured by the balance of reactive moments and the absence of a steering screw.

When deviations occur pedal differential movement of the upper and lower pitch propellers, which creates a different torsional moments and reactive. Simultaneously with this process deviate guides the vertical tail rudder in the tail. Differential mechanism makes installation angles of the blades increase by a screw, and the other - to decrease. The overall thrust remains unchanged.

Symmetrical Ka-29 in aerodynamic terms during a combat maneuver in the hanging or moving state slightly depends on the wind or other weather conditions. This ability to just a positive influence on landing or taking off from the deck of a moving ship.

This unit is the first Soviet helicopter, which is able to make the flat (foot) spread over the entire range of flight speeds. The helicopter is able to quickly take the right position to attack and not to lose its accuracy.
