Ka-126

 Ka-126 engine. dimensions. story. capacity

The Ka-126 is a further development of the Ka-26 helicopter with a CCD instead of two PD. Design began in helicopter 1984 city, which was initially considered the helicopter project with two GTE in small pods on the sides of the fuselage, however, preference was given to projects with a helicopter turbine engine on top of the fuselage.

AT 1985 g. It signed an agreement with the Romanian firm “AND” the joint development of the Ka-126 and its mass production under license in Romania. At the beginning of 1986. stand was built for ground tests helicopter systems, and a year later made the first flight of the first prototype of the helicopter. The four pre-series helicopters were built, one of which was built in the USSR (It made its first flight 19 October 1988 of the year), and the other in Romania (the first flight of the Ka-126 Romanian production took place 31 December 1988 of the year). first 10 serial helicopters, IAR under the designation Ka-126, It was built in 1991. the factory of the company “AND” in g. Brasov. Planned mass production of Ka-126 in Russia at an aircraft factory in g. Ulan-Ude.

The Ka-126 equipped with a CCD TVO 100 KB Omsk Motors with takeoff power 530kVt, provide a significant increase in available power and improving helicopter performance characteristics at higher duty.

modifications

Ka-126 helicopters were made in two variants:

– and a multi-purpose transport - with cargo-passenger cabin;

– Agricultural - without cargo cabin with large- and srednekapelnym sprayer or spinner, and further - with ultramaloobemnogo sprayer device and for dissipating granular herbicides; versatility Ka-126 is due to the possibility of hitch removable equipment for various purposes.

Passenger helicopter Ka-126

Built modification Ca-128 - one with TBG French production Turbomeca “Arriel” 1D1 with takeoff power 532kVt, which has at the same weight data, as the Ka-126, best flight characteristics. Planned mass production of Ka-128 at the plant in g. Ulan-Ude Helicopter FAA certification standards in the US 1996 year.

Built modification Ca-226 - a power unit of the two production GTE US Allison 250-S20V, take-off power of 308kVt, providing greater safety and better flight performance.

Agricultural Ka-126

helicopter structure is basically the same, like the Ka-26, with extensive use of composite materials. Improved aerodynamic shape by removing the nacelle, GTD is located on top of the fuselage, nozzle is bent upward. The transmission system is included inertial energy storage device with two counter-rotating flywheels, rotating at a speed of 24800 rev / min and provides the opportunity to continue flying for 40c when the engine failure. In the fore part of the cab air filter installed. The blades of the rotors are provided with electrothermal deicing system.

Power plant Ka-126 consists of a turboshaft TVO GTD-100, with free turbine, developed on the Omsk Engine Design Bureau, with power take-off and cruising power 530kVt 343kVt. The engine has a modular design, two axial and one centrifugal compressor, an annular combustor and a two-stage turbine. The degree of pressure rise 9.2; output shaft rotational speed 6000 rev / min. Engine length 1.275m, 0.78m width, 0.735m height, 160kg dry weight of the engine.

The helicopter set enhanced main gearbox VR-126m, two-stage, planetary, geared with Novikov gearing, adapted to drive the coaxial rotors, and the aggregates; designed for single-engine helicopters Ka-126 and Ra-128 and Ka-226 twin-engine.
