Encyclopedia - Mil Mi-26

Work on a heavy lift helicopter started in the 1970's designed by Marat Tishchenko, protégé of Mikhail Mil. The project Izdeliye 90 was later designated Mi-26. The Mi-26 first took flight in December 1977 where after it took 3 years to set up manufacturing facilities at the Rosvertol factory in the southern Russian city of Rostov-on-Don.

With a range of 800km and a sling load capacity of 20 000kg the Mi-26 dubbed HALO is often used for abnormal load transportation.

The Mi-26 has a crew of 5 and a closed circuit TV system to assist pilots with situational awareness.

Mi-26M is the latest and most powerful variant. All M-version Halos are equipped with two ZMKB Progress D-127 turboshaft engines. These engines each produce approximately 14 000 shaft horsepower. This additional power increases the maximum payload to 24 970 kg. The additional power provided by these engines also allows maximum payload-carrying ability at high altitude and in warm weather, conditions that are generally detrimental to any helicopter's performance
