History Mil Moscow Helicopter Plant Mil Mi-26,
NATO reporting name: Halo
The Mi-26's unique main gearbox is relatively light at 3,639 kg (8,023 lb) but can absorb 14,700 kilowatts (19,725 shp), which was accomplished using a non-planetary, split-torque design with quill shafts for torque equalization. The Mil Design Bureau designed the VR-26 transmission itself, due to Mil's normal gearbox supplier not being able to design such a gearbox. The gearbox housing is stamped aluminum. A split-torque design is also used in the 5,670 kg (12,500 lb) gearbox assembly on the American three-engine Sikorsky CH-53K King Stallion. As of 2024, the Mi-26 still holds the Fédération Aéronautique Internationale world record for the greatest mass lifted by a helicopter to 2,000 metres (6,562 ft) – 56,768.8 kilograms (125,000 lb) on a flight in 1982. But this record exists only because for the record flights of the Mil V-12, only the maximum payload was recorded, and not the maximum take-off weight, estimated at 105,000 kg

Design
An Aeroflot Mi-26 at the 1984 Farnborough Air Show Following the incomplete development of the heavier Mil Mi-12 (prototypes known as Mil V-12) in the early 1970s, work began on a new heavy-lift helicopter, designated as the Izdeliye 90 ("Project 90") and later allocated designation Mi-26. The new design was required to have an empty weight less than half its maximum takeoff weight. The helicopter was designed by Marat Tishchenko, protégé of Mikhail Mil, founder of the OKB-329 design bureau

Operational history

The developers of the Buran space vehicle programme considered using Mi-26 helicopters to "bundle" lift components for the Buran spacecraft, but test flights with a mock-up showed this to be risky and impractical.

In October 1999, an Mi-26 was used to transport a 23-tonne (25-short-ton) block of frozen soil encasing a preserved, 23,000-year-old woolly mammoth (Jarkov Mammoth) from the Siberian tundra to a lab in Khatanga, Russia.
