One of the main advantages of transport helicopters is the flexibility of their use. They can carry out freight traffic in areas where the use of transport aircraft is not possible. For transportation of large-sized cargo of large mass there is a special class of heavy transport helicopters (TTV), among which the undoubted leader today is Mi-26.

By the beginning of the 70-s, the Soviet TTV was represented by Mi-10 and Mi-6 helicopters, which were excellent in their class and outperformed all foreign counterparts.

Nevertheless, in connection with the increase in the volume of cargo transportation, it was required to replace these helicopters with a more perfect one. In 1970, the Moscow Helicopter Plant named after M.L. began work on the creation of such a machine. Responsibility for the organization and work on the project was assigned to the chief designer Smirnov GP. and his deputy Samusenko AG. Bakhov О.P. Acted as a lead designer. A classical single screw scheme was adopted. By December 1971, the project of a heavy Mi-26 helicopter (90 product) was developed. 14 December 1977 took place the first flight prototype. At the same time, preparations were under way for the launch of the machine in batch production.

 

The designers decided to install on the new helicopter two aircraft turboshaft gas turbine engines GTD D-136 (2 X 8380 kW), which by this time was being developed by the Zaporozhye motor-building design bureau "Progress". The power plant was equipped with an automatic propeller speed control and power synchronization system. If one of the engines failed, the second automatically switched to maximum power, which allowed the helicopter to continue flying. The design of the engines was modular, which greatly facilitated maintenance and repair.

The supporting screw is eight-bladed, its diameter is 28 m. The blades are made of metal-plastic. In the design of the main rotor hub, a titanium alloy was used for the first time. All this allowed to significantly reduce the total weight (almost by 40% compared to the five-bladed screw Mi-6). The steering screw is five-blade, the blades are made of fiberglass.

fuselage design also has a number of innovations that allowed to surpass the Mi-6 on the characteristics of the cargo compartment nearly doubled.

 

 

Mi-26 Cabin

 

Mi-26 is actively used in army and civil aviation. It can transport various cargoes (20000 kg in a cargo cabin or 18500 on an external suspension), including equipment, as well as passengers (85 soldiers in full equipment or 60 patients on stretchers). The helicopter was used in the work to eliminate the consequences of the Chernobyl accident. It was used for transport and rescue operations during various military conflicts on the territory of the former USSR.
