Mi-171A2

The Mi-171A2 is the civil market version of the Mi-171M military transport helicopter. Over 80 innovations are planned to be used on the Mi-171A2 helicopter achieving improved performance over previous Mi-8/17 models. The cost of flight hour on the highly affordable Mi-171A2 will be less than on the Mi-17/171 helicopters keeping a key advantage in the export market. Its service life will greatly increase as well as the time between overhauls (TBO) with future growth to make possible multifunctional test and control checks with modern on-ground maintenance equipment. The operating manuals will meet the best international standards. The first aircraft is expected to get airborne in 2014 and enter serial production with first customer deliveries in 2015. The helicopter will be fitted with two more powerful VK-2500 engines than the current TV3-117 turboshafts, an Auxiliary Power Unit (APU) with launch altitude up to 6,000 meters, a modernized main gearbox, swash plate, main rotor head, transmission, composite main rotor blades, and X-shaped tail rotor. The aircraft's crew will be brought down to two. The Mi-171A2 will be fitted with a digital autopilot in standard configuration, and will offer a glass cockpit as option. The range without additional fuel tanks will reach 850 km, the helicopter will carry up to 5,000 kg externally and fly at a higher cruise speed. The Mi-171A2 will be more stable in flight and will be able to hover at higher side wind speeds. It will have a -50 to +50 Celsius operating temperature range in all climate zones.
