1 GENERAL INFORMATION

The Mi-171 is a transport single-rotor helicopter. The helicopter is powered by two TV3-117VM gas turbine engines equipped with dust protection devices (DPD). The Mi-171 helicopter is a universal transport. Its spacious cargo cabin (23 m3) enables to carry up to 4 tons of cargo including wheeled vehicles. Moreover, the helicopter can be used for service passengers transportation and medical evacuation. It takes few minutes to install 36 seats or up to 12 stretchers. Two side doors and a hydraulically driven rear ramp facilitate loading/unloading of cargoes and passengers. In case of emergency 36 people can leave the helicopter within 15 seconds. The Mi-171 can also fly with an open ramp which allows to carry long-length loads inside the cabin and perform paratroopers dropping. To transport bulky cargoes the helicopter is fitted with a 4-ton capacity external sling. To increase the range of flight up to four 915-litre capacity auxiliary fuel tanks can be installed inside the cabin. Thus the range of flight can be increased up to 1,600 km. On customer's request the helicopter can be equipped with a 300-kg or 150-kg capacity hoist, as well as with other additional equipment. The helicopters can be used for carrying: • Carrying up to 20 person + 3 crewmembers; • Carrying cargo inside fuselage (up to 4 metric tons); • Carrying cargo on external sling load up to 4,5 metric tons; • SAR operation; • Night Flight operations; • Fire fighting; • Medevac. The minimum crew: Pilot (Captain) and Copilot. Another crewmember (a flight engineer or a loadmaster) may be added to the crew.

2.4 Cargo compartment Basic Data Volume, cu. m 25.0 Length (on the floor), m 5.34 Width, m 2.34 Height, m 1.8 Portside sliding widened door doorway size 1,405x1,215 m Starboard sliding door doorway size 1,405x0,825 m Rear ramp sizes 1,500x2,300 m The cargo compartment is comfortable and provides all necessary comfort for passengers. Fire – resistant materials are used for the cabin. To maintain normal temperatures, air purity in the cabin, to reduce noise, the helicopter is equipped with air conditioning, ventilation or heating systems and it is made heat-and –sound proof. Cargo Carrying If necessary, the helicopter can carry loads in the cargo cabin. The cargo can be loaded into the cabin through the doors or through the open ramp. Depending on the amount of cargo to be carried, the required number of the seats is folded to accommodate it. The cargoes are tied down to the tie-down fittings located on the floor. Any long-size bulky loads can be carried on the external sling. The helicopter is provided with external sling load system of up to 4500 kg lifting capacity (fitted as option equipment, standard capacity is 3000kg).

The helicopter fuselage is an all-metal structure made up of a nose portion, central portion, tail boom and tail boom pylon. The stabilizer is installed on the tail boom to provide the required stability and controllability. left sliding widened door - 1,405 x 1,215 m right sliding door size - 1,405 x 0,825 m In the rear part of cargo compartment is installed hydraulic driven ramp (Fig 2-2). The ramp is designed for rolling wheeled transport means, rapid airdrop and long-size loads carriage, embarkation disembarkation of stretches with injured. Operation of ramp is performed by the independent hydraulic system. Hydraulic system is filled with АМГ-10 oil that fills the hydraulic cylinder that enables opening and closing of ramp. Ramp is locked by hydraulic lock and is operated automatically as well as by manual pump (in case of automatic failure). The ramp is a high performance advantage during loading and unloading.
