I caught this segment of video on Discovery Channel. Damn this thing is bad ass – the world’s largest helicopter. It’s even more powerful than the mighty AC-130 Hercules!!
The Mi-26 helicopter, the heaviest and most powerful helicopter in the world, was designed for carrying large-size cargoes weighing up to 20 tons. It is the result of an early 1970s specification for a transport helicopter whose empty weight, without fuel, was not to exceed half of its maximum take-off weight. It can be used for construction projects ranging from bridges to power transmission lines. The combination of high load-carrying capacity and high cruise speed makes the use of the helicopter economically efficient. The helicopter is loaded through the cargo hatch in the tail of the fuselage with lowered ladder and sub-ladders. The cargo cabin is equipped with two electric hoists and lifting and loading devices ensuring loading and carrying along the cabin of cargoes weighing up to 5 tons. Mil Moscow helicopter plant joint stock company is the major designer and producer of military transport, civil transport, heavy-lift,multi-role helicopters. Mil is associated with the Rostov and Kazan production enterprises. Rostov makes the Mi-26 heavy-lift helicopters. The Mi-26 is the first helicopter with an eight-blade main rotor, which is mounted above the fuselage midsection on a hump. Two turbo shaft engines are mounted on top of the cabin with round air intakes above and behind the cockpit and exhaust ports at the sides of the engines. The long, bus-like body with fixed tricycle landing gear tapers to the nose and rear, with an up swept rear section and rounded nose and stepped-up cockpit. The tail is swept-back with a slightly tapered fin with large rotor on right side. The flats are forward-tapered and low-mounted on leading edge of the fin. The HALO A has no armament. The load and lift capabilities of the aircraft are comparable to the US C-130 Hercules transport aircraft. The length of the landing gear struts can be hydraulically adjusted to facilitate loading through the rear doors. The tailskid is retractable to allow unrestricted approach to the rear clam shell doors and loading ramp. The cargo compartment has two electric winches (each with 2,500 kg capacity) on overhead rails can move loads along the length of the cabin. The cabin floor has rollers and tie-down rings throughout. The HALO has a closed-circuit television system to observe positioning over a sling load, and load operations. The Mi-26 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. If one engine fails, the other engine�s output is automatically increased to allow continued flight.
- Mi-26MS: Medical evacuation version.
- Mi0-26T: Freight transport.
- Mi-26TZ: Fuel tanker with an additional 14,040 liters of fuel in 4x internal tanks and 1,040 liters of lubricants, pumped through 4x 60-meter long refueling nozzles for refu-eling aircraft, and 10x 20-meter long hoses for refueling ground vehicles. Fuel transfer rate is 300 liters/minute for aviation fuel, and 75-150 liters/minute for diesel fuel. The refueling system can easily be removed to allow the aircraft to perform transport missions.
