2–4 February 1982: Over a three-day period, several flight crews set a series of Fédération Aéronautique Internationale (FAI) payload-to-altitude world records at Podmoskovnoe. They flew an OKB Mil Design Bureau Mi-26 heavy lift helicopter.
On 4 February, Colonel Sergey V. Petrov and A. Chetverik lifted 15,000 kilograms (33,069.4 pounds) to 5,600 meters (18,373 feet).¹ On the same day, A. Kholoupov flew the helicopter to 4,600 meters (15,092 feet) with a payload of 20,000 kilograms(44,092.5 pounds).²
The Mil Mi-26 (NATO code name: Halo) first flew on 25 October 1977. It is a twin-engine heavy-lift helicopter, normally operated by a flight crew of five, and can carry up to 90 passengers.
The Mi-26 is 40.025 meters (131 feet, 3¾ inches) long, with all rotors turning, and has a height of 8.145 meters (26 feet, 8¾ inches). The eight-bladed main rotor has a diameter of 32.00 meters (105 feet) and turns clockwise, as seen from above. (The advancing blade is on the left.) A five-bladed tail rotor is mounted on a pylon, to the right side of the aircraft, in a tractor configuration. It turns clockwise, as seen from the helicopter’s left.
The helicopter has an empty weight of 28,200 kilograms (62,170 pounds), gross weight of 49,600 kilograms (109,350 pounds) and maximum weight of 56,000 kilograms (123,450 pounds). The fuel capacity is 12,000 liters (3,200 gallons).
The Mi-26 is powered by two Lotarev D-136 turboshaft engines which are rated at 8,500 kW (11,299 shaft horsepower), each. It’s cruise speed is 255 kilometers per hour (158 miles per hour) and the maximum speed is 296 kilometers per hour (183 miles per hour). Range is 620 kilometers (385 miles). The service ceiling is 4,500 meters (14,765 feet).
320 Mil Mi-26 helicopters have been built.
