Heaviest and most powerful helicopter


The Mil Mi-26 (Миль Ми-26) is a Russian/Soviet heavy transport helicopter in service in civilian and military roles. The Mi-26 was designed for military and civil use and intended to be able to lift more than any previous helicopter. The first Mi-26 flew on December 14, 1977 and the first entered service in the Soviet military in 1983.

The Mi-26 was the first helicopter to operate with an eight-blade rotor. It is capable of single-engine flight in the event of loss of power by one engine (depending on aircraft mission weight) because of an engine load sharing system.
