Mil Mi-26 Features

The Mi-26 is composed of eight principal rotor blades on the middle of the fuselage and also five tail rotor blades on the hump. Likewise, the heavy load capability and the high speed of the cruise allow for the economic efficiency of the helicopter. A freight cabin at the back of the cockpit is also part of the helicopter. Thus, two fighting vehicles of approximately 1000 kg can be installed in the 12m long, 3,3m wide and 3,2m high compartment. The cabin is fitted with two electric winches on the overhead track. The camera also has a closed-circuit TV camera for monitoring slung load positioning.

The Mi-26 helicopter also features electrically de-iced head and tail rotor blades, infrared jammers, infrared removals, infrasound dispensers and a colour coding flare protection mechanism to shield the helicopter from ballistic missiles. On the whole, infrared jammers interrupt the propagation of infrared signal and shield the helicopter from infrared rockets.

Engine, Cockpit & Landing Gear

The cockpit accommodates the pilot, co-pilot, flight engineer, navigator and radio operator five aircraft, pressurized to optimize visibility. However, in the front of the cockpit control panel, the pilot and co-pilot seat neighbour to each other. Also, on the rear of the pilot’s seat are the flight engineer and navigator chairs. It has a tricycle lander and two steering nose wheels that is not retractable. Thus, the hydraulic crane enables the loading of various surfaces utilizing ladders and sub-leaders via back doors. Installation weight on the main gear racks on the rear side of the aircraft engineer seat can also be reflected in a sensor or electronic screen.

Two Lotarev D-136 turbocharged engines power Mi-26 and the capacity of each motor is 8,380 kW. Also, a consistent rotor rpm is maintained by the synchronization of outputs of both engines. Nonetheless, in the absence of the first engine, the second engine’s output is raised to full power. Titanium is also produced for each engine bay to protect against fire. Each tank has 12,000 litres of full inner fuel capacity.
