In the 50s of the last century, Soviet polar explorers began active exploration of the Antarctic. For these purposes, special reliable transport was required, since the available equipment could not withstand the harsh operating conditions. The first machine that met these requirements, could work at extremely low temperatures, was the Kharkivchanka all-terrain vehicle. Consider the features and characteristics of this technique.

History of Creation

Separately, it is worth noting the predecessor of the machine in question. In 1957, the Penguin swamp was developed and quickly created, based on the base of the PT-76 tank. This representative of off-road equipment was of great help in the development of the Antarctic expanses. The unit proved to be a reliable machine with a decent running resource. But there were two significant drawbacks in its design: it was not intended to travel long distances and was cramped inside.

All-terrain vehicle "Kharkovchanka"lost those disadvantages. The car became more comfortable and spacious, which made it possible to send large groups of people who spent a long time on the road to transatlantic expeditions. Some experts compare the machine to a snow cruiser geared towards polar climates.

Description

The new machine was built as part of the "Product No. 404-C" project. The creation of equipment took place at the transport construction plant in Kharkov. The heavy tractor AT-T, intended for the needs of artillery, was taken as the basis for the design. Its base was increased by a couple of rollers, the frame turned out to be hollow and completely sealed. In its frontal part, a diesel power unit with 12 cylinders was placed. A five-speed gearbox, oil reservoirs, controls and a main fuel tank were also placed there.

The other eight fuel tanks of the Kharkivchanka all-terrain vehicle were installed in the middle frame compartment. Their total capacity was 2.5 thousand liters. At the back, heaters with a capacity of 200 cubic meters of hot air per hour, as well as a powerful hundred-meter winch, were mounted. As a result, the overall layout of large parts under the floor made it possible to free up more space for passenger modules and significantly reduce the center of gravity of equipment, the total height of which reached almost four meters.

Design and equipment

The dimensions of the Arctic all-terrain vehicle "Kharkovchanka" are impressive. The length of the vehicle was 8500 millimeters, and the width was 3500 mm.The rectangular one-volume body inside was equipped with a room with a total area of ​​​​28 "squares" with a ceiling height of 2.1 m. Such dimensions made it possible for the team to move freely around the cabin. The specified area was carefully isolated from the running block, had serious insulation and was divided into special compartments.

Inside the all-terrain vehicle "Kharkovchanka", in the frontal part above the engine, a control room was provided, where the navigator and the driver worked. On the right side (in the direction of travel) a radio headquarters was equipped, which was equipped with the most modern equipment at that time. Behind the partition on the left there was a sleeping room for eight people, and behind it - a wardroom. The layout even provided for the arrangement of the kitchen (galley). However, it was not suitable for full-fledged cooking, more often it was used to heat canned food. Behind this compartment, a heated toilet was equipped. The design features of the machine included the presence of a small clothes dryer, as well as a vestibule, which made it possible not to cool the air during landing and exit.

Operation

Since the Antarctic all-terrain vehicle "Kharkovchanka" was intended for operation in conditions of loose snow, and its composition is not inferior in hardness to sand, forming "quicksands", the designers made a serious revision of the tracks. To prevent the elements from sinking from the slightest contact with snow layers, their width became 1000 millimeters, while a snow hook was equipped on each track.

This decision made it possible to increasetractive effort, allowing the car to literally bite into the crust. The hooks have additional functionality. They helped the technique to overcome water obstacles if necessary. Despite the fact that the Kharkivchanka all-terrain vehicle did not belong to the class of amphibians, it could easily swim a certain distance through the water. Here it was necessary to show special care to the driver and navigator, making sure that the car did not sink below the floor level. The buoyancy parameter was provided by a hollow and sealed frame.

About the engine

The following are the main parameters of the power unit that set the specified equipment in motion:

  • power rating at par - 520 "horses";
  • the presence of turbine superchargers to double the power;
  • fuel type - diesel fuel;
  • working/maximum speed - 15/30 km/h.

The motor of the Kharkivchanka Antarctic all-terrain vehicle (see photo below) easily transported the car's own weight (about 35 tons), and also made it possible to tow a trailer weighing up to 70 tons. Most often, these were containers with fuel, since in such expeditions it is the most important cargo. Its part among the total volume was about 70%. It is worth noting that as part of the sleigh train, the speed was about 12-15 km/h.

Design features

From the nuances of the design, it should be emphasized the presencemoisture absorbers with a constant influx of hot air masses. This made it possible to avoid possible freezing of the windows. Electric heating was provided on the windshields, similar to modern automotive analogues. The generator of the machine in question was capable of generating about 13 kilowatts of electricity per hour. This was quite enough for the needs of the expedition members.

Judging by the reviews, thanks to the unique layout, the Kharkivchanka all-terrain vehicle in the first generation was in operation for quite a long time (until 2008), and some models still serve. The second generation of this technique appeared already in 1975 and was equipped with a separate residential module. The features of this machine will be discussed below.

As for "Kharkovchanka-1", the operation of these modifications indicates that it is convenient to service the engine without leaving the passenger compartment. Nevertheless, it was not possible to completely level out the exhaust gases breaking inward. And this significantly reduced the comfort of staying in the living compartment. The thermal insulation of the first versions was also not at the highest level.

Second Generation

The first generation of the considered all-terrain vehicle was quite reliable, but did not meet modern requirements. In this regard, the Kharkov plant in 1974 received a new order for five improved machines. Taking into account the operating experience and recommendations of the polar explorers, the designers made certain adjustments to the design and life support system of the equipment. The updated unit was called "Kharkovchanka-2". speci althe complexity for the engineers was presented by the modernization of the residential part. It was also necessary to equip the complex with radio navigation software.

As a result, they have achieved a comfortable microclimate inside, despite the strength of the frost outside. Even with a system failure, the temperature in the cabin dropped by no more than 3 degrees per day. The implementation of this solution became possible due to the use of modern thermal insulation materials. The engine hood and driver's cab remained the traditional configuration. At the same time, the residential part was transferred to an elongated cargo platform. Taking into account the recommendations of the polar explorers, the developers at the last moment made a window for ventilation. This innovation was equipped literally before sending the updated machines to Antarctica. The all-terrain vehicle "Kharkovchanka" in the late 80s received another restyling with a base in the form of an MT-T tractor, but after the collapse of the USSR, the project was never implemented.

Result

Judging by the reviews, this technique is still functioning. Moreover, some experts are convinced that there is no better car in their segment. This fact is confirmed by the fact that in 1967 the expedition reached the most remote point of the South Pole and returned without any problems. No one else has visited this part of the Earth since Kharkiv Women.
