Ka-26

 Ka-26 Engine. dimensions. The weight. story. Range of flight

AT 1956 in the Soviet Union began to make extensive use of Mi-1 helicopters and Ka-15 in agricultural work: soil fertilizer on the fields, in orchards and vineyards, as well as the fight against noxious weeds and insects. The experience proved to be very effective. There was a large expansion of air-chemical Preventive. Since this is not fully able to handle any of the Mi-2, Our An-2. Immediately it became clear, that there was a need for a multi-purpose helicopter. The Ka-26 has become such an air machine.

CAF has become the main customer of construction of this helicopter (1964 year). Feature was its exclusive use. Ka-26 was a helicopter with two piston engines and four landing gear, which in turn led to the non-ideal aerodynamically. One side, he was slow (although the rate of employment for the helicopter and do not need), but, with another, We commend compact, high thrust, maneuverability and simple technique of piloting.
Considering the criteria of cost and performance, The Ka-26 is considered one of the best helicopters. In comparison with the same Ni-2 may be mentioned, Ka-26 that has a lower power motor and smaller weight, that does not prevent him to carry the same weight, how and Mi-2. A range and flight time is more than doubled.

Almost all exploiters of this flying machine celebrate a special flair - the presence of fiberglass rotor blades, resource which is ten times greater than the metal blades of Mi-2. manufacturing technology design has been concreted in 5 foreign countries. Ka-26 - this is the only helicopter in the USSR, which has received the certificate of American standards of airworthiness.

modifications

seven modifications were designed for three years:

– Agricultural. On replacement cargo cabin mounted tanks or hoppers for spraying and splashing of chemicals (the spray width of the strip 20 to 60 m).

– Transport. It has a cargo cabin for six people, a loading platform on the weight of the load 900 kg.

– Sanitary. Special passenger cabin with two seats, adapted for patients on stretchers, paramedic with equipment.

– Forest-patrol. Mainly used for patrolling forests and mountain ranges, carry out rescue operations in fires. Inside the helicopter mounted electric winch LPG-150.

– Flying crane. Widely used for weight lifting works to 900 kg.

Ship rescue. It winch placed LAH-150-M3 (victims lifting system), lifeboat LAS 5M3 (It has a radio station "Coral", a television camera and emergency ballonets).

– Patrol. used Inspectorate, respectively, on the helicopter were installed speaker, elektrolebodka, load hook. In some situations, modified TV camera.

Agricultural Ka-26

It was designed for the entire period of about 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 the OKB NI. Kamov, chief designer of M. Kupfer, leading designer Yu. Petruhina, The test engineer. Dordina and test pilots. Gromov and E. Laryushin.

The design of the Ka-26

The fuselage is combined in the form of "flying chassis" with center compartment - rectangular platform, whose front installed cabin crew, and placed behind the two tail booms with a horizontal tail. Above the central compartment mounted main gear unit with the host system, and on both sides - the gondola with engines M-14V26.

double cabin, with a good view and sliding doors. It is also the setting of reserve management kit. Rear seats placed crew compartment of the instrument and avionics. Transport helicopters, cargo-landing modification equipped with quick-suspended cab with dimensions 1,28 x 1,37 x 1,84 m and folding seats for six passengers. Enter into the cabin is possible only through the double doors, and placed in the floor hatch (0,5 x 0,7 m). It is used for landing and lifting people. The entire cabin is constantly using ventilation, present heating system and acoustic.

Tail booms are constructed of an aluminum alloy monocoque. They set the horizontal and vertical tail. Horizontal covers an area of ​​up to 1,97 m2, it consists of the stabilizer wheel and chord. Vertical tail consists of two rudders dvuhlonzhernoy design and fiberglass lining.

Four chassis, fixed landing, with form supports and brake wheels (polwbalonnıy type). To the main pillars are mounted transverse vibrations dampers. supports front, samooryentyruyuschyesya, with polubalonnogo type wheels. The size of the main pillars of potassium - 2,24 m, front - 0,9 m, base chassis -3.48 m.

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

The blades of screws are shown in the trapezoidal form with the chord profiles and. They are made of phenolic-epoxy binder and fiberglass (fiberglass). Hollow spar variable section, mounted thereto tail sections and a steel blade assembly. Sock protected blade wear resistant rubber coating, inside which a counterweight is located. At the end of the blade is installed with the antifreeze fluid chamber, from which the supply to its toe.

The star-piston engines M 14V26 constitute powerplant (set designer IM. Vedenev). They are placed in the side of the central fuselage cell gondolas. Engines composed of nine cylinders, reducer, centrifugal fan and odnoskorostnoho nahnetatelya.

The fuel system includes two front and one rear tanks. Total capacity - 630 liters. In additional tanks installed on the individual capacities of 160 liters. For oil system includes an oil tank (38 liters), oil pumps and oil cooler. The transmission consists of two gearboxes, Combined clutch, gear rotors and connecting portions. Clutch engine and gearbox - are components of M-14V26.
Reducer main propellers (P-26) planetary, two-stage, It is used to transmit power from the engine to the rotor shafts.

The electrical system is fully monitored systems and helicopter equipment:

  • direct current circuit, includes generators GDS-3000;
  • accumulator battery;
  • converters;
  • alternating current circuit.

Military Ka-26

All additional equipment Ka-26 is designed to perform specific tasks. For agricultural work includes the promotion of liquid chemicals (tank capacity 800 l, suspended from the central compartment) and spraying chemicals bulk type (hopper capacity 800 liters).

Distribution and sputtering is performed by a special system. Breathing protection pilot works on the principle of a gas mask. The helicopter mounted air purification mechanism and a filter installed Specialized absorber.
Helicopter Flight in severe weather conditions is provided by navigation equipment. It consists finder, radio R-860 and heading system.

Passenger helicopter Ka-26

AT 1964 year, Resolution of Government of the USSR, it was decided to manufacture multi-purpose helicopter by request and for the needs of the Soviet Union civil aviation – Ka-26. Actually, it is a unique case, the first and only helicopter is not for military purposes.

The appearance of this car, It was caused by the increase in the workload of small aircraft in agriculture and the existing fleet, I have not mastered the tasks.

Above developers helicopter, there was no strict requirements of military customers, this made it possible creative initiative.
The layout of the helicopter, It was far from ideal aerodynamics. helicopter, this class, it was not so important. But its coaxial scheme, four landing gear allows to carry out a very subtle maneuvering while working. blades, this helicopter, They were first made of fiberglass. Resource exploitation was 10 times higher, than metal blades (5000 hours against 500).

The chassis has been designed, on the principle of "flying chassis". such a method, allowed to expand the scope of Ca-26. During the production was released in all 800 machines of different modifications.

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