For the first time, the B-12 took off on July 10, 1968 under the control of test pilot V.P. Koloshenko. The second copy took off in May 1973 under the guidance of test pilot G.V. Alferov. Both copies were sent to the aviation museum in 1974, where they are to this day. The production of such a large aircraft had to be closed due to the too high cost and the lack of suitable landing sites.

Mi-26

In second place among the largest helicopters was the Mi-26 - the younger brother of the V-12. Unlike its older "colleague", the Mi-26 is mass-produced by the Rostvertol plant and is used everywhere.

The main rotor of the machine consists of eight blades with a diameter of 32 meters, the tail rotor - of five blades with a diameter of about 7.5 meters. Two engines with a total capacity of 22.8 thousand hp. lift a machine weighing 28, 2 tons and additionally a load of up to 20 tons. Piloted by a crew of 2 to 6 people (depending on the model). Dimensions: height - 8 m, length - 40 m.

Today, the Mi-26 has up to 15 modifications that perform various functions and ensured wide popularity of the device. It is used for the transportation of goods, as well as:

  • for medical purposes for transporting the wounded: holds up to 60 beds and medical staff;
  • for military purposes: holds up to 85 soldiers;
  • in forest fire or natural disaster rescue operations.

The Soviet Mi-26 was first tested on December 14, 1977 by test pilot G.R. Karapetyan. Massively produced since 1984 and during this time has managed to "light up" in numerous military conflicts, rescue operations, peacekeeping missions, in the field of passenger and cargo transportation. The helicopter is in service and operated for civilian purposes in more than 15 countries around the world.
