Ka-26. A photo. Video. Characteristics.



In 1956 in the Soviet Union began to make extensive use of Mi and Ka-1-15 in agricultural work: soil fertilizer on the fields, orchards and vineyards, as well as the fight against weeds and harmful insects. The experience proved to be very effective, even started to connect to the work of a load-lifting Mi-2. There was a large expansion of aviation and chemical prevention. With this fully able to handle any Mi-2, or AN-2. Immediately it became clear that there was a need for a wide nazanacheniya helicopter. Ka-26 has become such an air machine.

CAF has become the main customer of construction of this helicopter (1964 year). A special feature was his exclusive use. Ka-26 was a helicopter with two piston engines and four-post rack, which in turn led to the non-ideal aerodynamic performance. On the one hand, he was slow (although the rate of employment for the helicopter and do not need), but, on the other hand, welcomes the compact, high traction, maneuverability and simple technique of piloting.

Considering the criteria of cost and performance, Ka-26 is considered one of the best helicopters. In comparison with the same Ni-2 can be noted that Ka-26 has less engine power and less weight, that does not prevent him to carry the same weight as the Mi-2. A range and flight time exceeds twice.

Almost all exploiters of this flying machine note a special highlight - the presence of fiberglass rotor blades, the resource of which is ten times greater than the metal blades of the Mi-2. Manufacturing technology design has been patented in 5 foreign countries. The Ka-26 is the only helicopter in the USSR that has received a certificate according to the American airworthiness standard.

seven modifications were designed For three years:

  • Agricultural. His replacement cargo-passenger cabin mounted tanks or silos for spraying and spraying of chemicals (up from 20 60 meters width spray bar).

  • Transport. It has a cargo cabin for six people, a loading platform on a weight 900 kg.

  • Sanitary. Special passenger cabin with two seats adapted for patients on a stretcher, paramedics equipment.

  • Leso-patrol. Mainly used for patrolling forests and mountain ranges, conducted rescue operations in fires. Inside the helicopter mounted electric winch LPG-150.

  • Flying crane. Widely used for lifting work up to 900 kg.

  • Ship rescue. It posted winch LPG-150-M3 (injured lifting system), lifeboat LAS 5M3 (a radio station "Coral", a television camera and alarm ballonets).

  • Patrol. Used Inspectorate, respectively, on the helicopter were installed speaker elektrolebёdka, cargo hook. In some cases modified TV camera.

Over the entire period it was constructed around 800 aviamashin factory in Kumertau. They were used in 17 foreign countries and set five world records. In the creation of this masterpiece was attended by the head of OKB NI KamovChief Designer M. Kupfer, a leading designer Yu Petruhin, engineer V. Dordina testing and test pilots Gromov and E. Laryushin.

Design Ka-26

The fuselage is combined in the form of "flying chassis" with central compartment - rectangular platform, which is installed in the front cockpit and the rear tail boom placed two horizontal tail surfaces. Above the central compartment mounted main gear with the host system, and on both sides - the gondola with engines M-14V26.

The cabin is double, with a good view and sliding doors. It also provides for the installation of a spare control kit. Behind the seats of the crew there is a compartment for instrumentation and radio electronic equipment. Transport helicopters of cargo-landing modification are equipped with quick-detachable hanging cabin with dimensions 1,28 x 1,37 x 1,84 m and folding seats for six passengers. Enter the cab is only possible through the double-leaf door, and in the floor there is a hatch (0,5 x 0,7 m). It is used to disembark and lift people. The entire cabin constantly uses ventilation, there is a heating system and soundproofing.

Tail boom monocoque constructed of aluminum alloy. They set the horizontal and vertical tail. Horizontal covers an area of ​​up to 1,97 m2It consists of the stabilizer and rudder chord. Vertical tail consists of two rudders dvuhlonzhernoy design and fiberglass sheathing.

The chassis is four-bearing, non-retractable, with shaped bearings and brake wheels (semi-ballon type). Lateral vibration dampers are mounted to the main supports. Front supports, self-orienting, with semi-ballon type wheels. The track size of the main supports is 2,24 m, the front ones are 0,9 m, the chassis base is 3,48 m.

Three-bladed rotors rotate opposite are hinged blades. From each other, are mounted at a distance of 1,17 m (taking into account the margin convergence). The hub of steel 40HNMA with vertical and horizontal spaced joints and axle with roller and ball bearings. They installed a central weight limiter and a hydraulic damper.

Screw blades provided in a trapezoidal shape, and with the chord profiles. They are made of epoxy-phenolic binder and fiberglass (fiberglass). The hollow spar variable cross-section, it is set to the tail section and the steel of the blade assembly. Sock blades protected by a wear-resistant rubber coating, which is located inside the counterweight. At the end of the blade mounted camera with antifreeze liquid, from which the supply to its toe.

Star-shaped piston engines M-14V26 up power plant (set designer Vedenev IM). They are placed in the side of the central fuselage cell gondolas. The motors consist of a nine-cylinder, gear, single-speed centrifugal blower and fan.

includes two front and one rear tanks in the fuel system. Total capacity - 630 liters. In some versions installed additional tanks with a capacity of 160 liters. For oil system includes oil tank (38 liters), oil pumps and oil cooler. The transmission consists of two gearboxes, combined clutch, gear rotors and connecting parts. Clutch Engine and gearbox - a component of the M-14V26.

Reducer main screws (P-26) epicyclic, two-step, is used to transmit power from the engine to the rotor shafts.

The electrical system provides a fully working systems and equipment of the helicopter:

  • DC circuit, comprising generators GDS-3000;
  • accumulator battery;
  • converters;
  • AC circuit.

All accessories Ka-26 designed to perform specific tasks. For agricultural operations provided for distribution of liquid chemicals (800 tank capacity l suspended from the central compartment) and spraying chemicals such as bulk (hopper capacity liters 800).

Distribution and spraying is carried out by a special system. Breathing protection pilot works on the principle of a gas mask. The helicopter is mounted air-cleaning mechanism and set Specialized filter-absorber.

Helicopter Flight in severe weather conditions is provided by flight-navigation equipment. It consists of radio compass, radio station R-860 and exchange rate system.


In 1964 year, the decision of the Government of the USSR, it was decided to manufacture multi-purpose helicopter on request and for Civil Aviation of the USSR - the Ka-26. In fact, this is a unique case, the first and only helicopter is not for military purposes.

The appearance of this machine, was caused by the growth of the volume of work of small aircraft in agriculture and the existing fleet, no longer cope tasks.

Over the developers of the helicopter, there was no strict requirements of military customers, this made it possible creative initiative.

The layout of the helicopter, was far from ideal aerodynamics. For helicopters of this class, it was not so important. But its coaxial scheme, four landing gear allowed to carry out a very subtle maneuvering while performing work.

The vanes of the helicopter for the first time were made of fiberglass. Resource exploitation was 10 times higher than that of the metal blades (5000 hours against 500).

The chassis has been designed on the principle of "flying chassis". Such a method is allowed to extend the scope of the Ka-26. During the production was released only 800 machines various modifications, namely:

  • Agricultural - with installed capacity for chemicals and their subsequent spraying onto the width 20-60m at flight speeds 30-130km / h;

  • passenger and cargo cab designed for 6 passengers or cargo weighing razescheniya 900kg;

  • Sanitary - equipped with a cabin for transporting two patients lying on stretchers and two - on the chairs, accompanied by a medical worker and installed special equipment;

  • forest patrol - used for inspection of the forest and if necessary rescue operations in the outbreaks of fire; Helicopter this modification mounted winch LPG-150, fracturing. 150kg .;

  • flying crane - for installation and movement of cargo weighing up to 900kg an external load;

  • life - for rescue work on the water, it was equipped with electric winch LPG-150-M3 and injured lifting system, a boat LAS 5M3 television camera; cylinders for emergency landing on water;

  • patrol - for the needs of the traffic police, equipped with all the necessary accessories - speakers, winch, cargo hook, a television camera.


During the production of this car, it was exported to 14 the world. Including in the GDR, FRG. Ka-26, was the only helicopter received while operating in the US.

Good time! And why not now produce such machines, the Ka-26?

The correct way out in the present situation is to change lean grazing to fresh peeled, which is specifically prepared specifically for heat treatment. The main condition - pay attention to the expiration date of such goods, for different types of products they are certainly different.

But in spite of everything there is still a folk trick - to add a couple of pinch of salt to the roasting dish, it neutralizes the foaming process.
