Ka-137. A photo. History. Characteristics.

 

Ka-137 - this helicopter with a wide range of problems (Ministry of Emergencies, the economy, the Ministry of Defence). It is based on the previously developed Ka-37, but has several advantages. The main of them - the difference in the application: the precursor is an experimental model, and Ka-137 directly multiplayer. A feature of the helicopter is considered to be its ability to operate in hazardous areas for the people (a prime example - the accident at the Chernobyl nuclear power plant).

This unit is able to perform the aviation engineering, chemical, biological and radiatsionnuyurazvedku. Can supply emergency loads spetsprednaznacheniya, implement and broadcast retransmission in hazardous locations and in extreme circumstances. The helicopter can be engaged in monitoring of environmental protection in areas such as gas and oil pipelines. It can control the forest borders of the state, important objects.

Ka-137

Design Ka-137 1994 began in the year. The sketch was finished a year later, and 96-m layout actual size built.

Ka-137 is an unmanned helicopter complex MBVK-137. It can be designed in three types:

  • 1) ground-mobile,
  • 2) ship,
  • 3) airmobile.

The unmanned helicopter complex accommodates from two to five Ka-137. The ground-mobile complex is designed on the basis of cars with increased cross-country capacity as KamAZ. The complex includes PPU-137, transport-operational machine, crane for unloading and loading of aircraft and replacement sets of airborne equipment. For controlling two or more UAVs, the mobile type control unit (PPU-137) is responsible. The transport vehicle is responsible for the transportation. The airborne complex is installed on a helicopter (directly Ka-32). The helicopter delivers an unmanned analog to the site of the operation. On board the Ka-32 there is also a point of operation and control.

Ka-137

Unmanned Ka-137 able to fly in any direction with no change in speed range. This feature makes it possible to move an unmanned helicopter in different climatic conditions regardless of weather conditions, wind direction and increased turbulence. And because of the automatic control system of the UAV is able to move equally well both day and night.

Characteristics of construction Ka-137

Helicopter fuselage has a spherical shape, and the circuit performance coaxial. The plumage is completely absent. The two rotors comprise a carrier system. The blades are rectangular and made of plastic and natural composites. The fuselage includes compartments: gear, engine and spets, electrical. It is entirely composed of skin and skeleton (beams, floors and frames).

Main gearbox, the drive from the alternating current generator, transmission, control units rotors, two fuel tanks and equipment unit located in the geared compartment. Engine compartment isolated from the rest of the fuselage special type of fire partitions. Compartment main equipment housed in the central part of the fuselage. It is equipped with a radome, is located on the axis of symmetry. This placement allows the many problems associated with the replacement module. At the bottom of the compartment are antenna devices.

Ka-137

The moment of inertia is minimized, since Ka-137 has a spherical shape of the fuselage. For a better interface with the ground engineers made chetyrёhampernoe chassis springs to bias. Supporting attachment points are located in places where the power stykayutsya beams and frames. For the landing gear using composite materials.

It is the power plant helicopter piston two-stroke engine capacity of up to Hirht2706 R05 50 kW, which was created at the company GoblerHirthmotoren. On the OP all categories established German engines. On the production models of the UAV used for domestic purposes, the engines were installed in Russia.

Ka-137

Avionics Ka-137 is a digital system of automatic control, on-board satellite navigation system, thermal or televizornaya cameras, radar sensors and Specialty transmission equipment. CA automatic control necessarily involves certain elements of artificial intelligence. BNSS inertial type and is able to provide automatic flight of light or complex trajectory. The total tonnage of devices - up to 80 kilos.
