Ka-126. Photo. Characteristics
Due to the huge need for multi-role helicopter in the USSR engineering organization Kamov design bureau was tasked to develop such an air unit. For this purpose it was decided to create a new modification of the helicopter on the basis of Ka-26. This modernized version called Ka-126 (codification of NATO - "Hooligan"). The basis was laid turbine engine TV-0-100 720 hp with power Helicopter project began considered 1984 year, and originally planned to create a helicopter with two GTE. They wanted to place in small pods on the sides of the fuselage. Experienced flight occurred in October 1987 years at the helm was a famous test pilot G. Isaev.
From the basic model have the best of everything. The main difference between the upgraded model from the previous Ka-26 was a modification of the power plant and the support system. Small changes have happened to the cockpit avionics. Improved maneuverability and control of the helicopter. Ka-126 planned to produce in Romania. The contract was signed in 1985 year.
In the course of work on the design of the helicopter were taken into account all the nuances and demands of both domestic and foreign consumers. Moment of inertia with respect to the helicopter axes decreased due to the absence of engine nacelles and installed close to the center of mass of the assembly. Due to this increased flexibility even more.
Simplified the technical operation of helicopters (changed to a piston engine turboprop), reducing the cost of the work performed. In the agricultural version of the Ka-126 increased load capacity of chemicals (due to an increase in theater). A maximum speed increased from 170 190 to km / h.
The experience gained in the Ka-26 useful for the new helicopter. Agricultural equipment improved and adjusted under the Ka-126. This simplified operation fertilizers and increase the total number of flight-chemical works. Truck cab is removable, which, unlike its predecessor, has allowed to establish emergency hatches on the side walls.
Follower Ka-126 was the export model Ka-128. Old engine was replaced by the French turbine "Ariel ID1» with a valid power 730 hp This model is characterized by high speed (up by ten kilometers per hour), the static ceiling (on 600 m) and flight range (in 50 km). These figures are consistent with the parameters of the engine.
For certified and factory testing OKB Kamov engineers have designed three prototypes. First 12 serial specimens collected on the territory of Romania. The flight of the first production cars held at the end of December 1988 years. Ten aircraft units got labeled IAR Ka-126, because they were designed in the factory in IAR Brasov. But because of the collapse of the Soviet Union and the tragic events in Romania, further production of the helicopter was discontinued.
Among the distinctive aspects in addition to the improved aerodynamic properties and remote gondolas, was also changed the angle of the nozzle up to the transmission mechanism have built in energy storage with two flywheels (like counter-rotating). Maximum speed Mokhovikov 24 800 / min. They also provide additional flight time 40 seconds in the event of an emergency incident with the engine. The air filter is installed at the bow. A system protivoobledelitelnoy (antifreeze) protection does not allow the rotor blades icing.
Especially for this helicopter Omsk motostroitelny KB created Turbo Shaft engine GTD TVO-100 (free turbine). Takeoff power powerplant is 530 kW and cruising, respectively, 343 kW. The engine is designed for the type of module - one centrifugal and two axial compressor, annular combustion chamber and two-stage turbine. Shaft speed is 6000 rev / min, and the degree is equal to the height of the pressure 9,2. Engine parameters: length - 1,275 m, height - 0,735 m, width - 0,78 m, weight in the dry state - 160 kg.
BP Chief improved gear-drive ensures 126M bearing assemblies and screws. It developed in a two-stage creation, planetary geared units. Used models of helicopters Ka-126, Ka and Ka-128-226.
- Ka-126 - prototype. The first flight in 1987 year.
- IAR Ka-126 - serial helicopter Romanian assembly.
- Ka-128 - export-type helicopter with the presence of Turbomeca Engine "Ariel-ID1» French production.
- Ka-226 - a helicopter with two engines GTD AI-450. In some embodiments, set "Allison 250-S20V." The first prototype flight in early September 1997 years.
In the future, further development of the helicopter in the city of Ulan-Ude for FAA certification in the United States.
Ka-126 (NATO code: Hoodlum - «Hooligan") - a multi-purpose helicopter with a turbine engine.
The helicopter is a constructive development of the Ka-26 with one instead of two GTE PD. Proektirvoanie multipurpose helicopter Ka-126 began in OKB. Kamov NK in 1984. The first flight of the serial Ka-126 19.10.1987 passed.
The first 10 helicopters, which were designated IAR Ka126, built in 1991 at the company «IAR» Brasov. On a helicopter main gearbox mounted improved VR126M, planetary, two-step, with the gears. Further development - twin-engine turbine helicopter Ka-226.
