The Civil Aviation Service of the Socialist Republic of Vietnam (CAAV) has validated the type certificate of the Mi-171A2 multipurpose helicopter produced at the Ulan-Ude Aviation Plant of the Russian Helicopters holding. This event opens the Vietnamese market for the latest modification of the Mi-8/17 helicopter family.
Earlier, on March 13, 2020, the Federal Air Transport Agency (Rosaviatsia) and CAAV signed a working agreement on airworthiness issues aimed at supporting and simplifying the validation of Russian aircraft exported to Vietnam. These events are carried out by the Federal Air Transport Agency in support of the priority plan for the export deliveries of promising domestic aviation equipment, formed by the Ministry of Industry and Trade of Russia and enterprises of the Russian aircraft industry.
The first foreign operators of the Mi-171A2 were Kazakhstan and India. The helicopter type certificate has been validated by the aviation authorities of India, Colombia, South Korea and now Vietnam. In addition, the Mi-171A2 certificate is also planned to be validated in China, Brazil, Mexico, Peru and other countries.
The Mi-171A2 helicopter has embodied the best characteristics of the world famous Mi-8/17 aircraft. It is equipped with VK-2500PS-03 engines with a digital control system. Increased power engines and an upgraded complex of flight, navigation and radio communication equipment have expanded the scope of the helicopter. They provide the Mi-171A2 with fundamentally new capabilities when operating in high-mountainous regions and areas with hot climates. Thanks to a more efficient X-shaped tail rotor, a new main rotor with composite blades, as well as an improved aerodynamic profile, the cruising and maximum speed of the Mi-171A2 relative to the serially produced Mi-8/17 helicopters increased by 10%, and the carrying capacity – by 25% (up to 4 tons of cargo inside the cargo compartment or up to 5 tons on the external sling).
The use of the KBO-17-1 digital avionics complex on the Mi-171A2 helicopter, designed according to the “glass cockpit” principle, made it possible to reduce the crew to two people. The use of video cameras has improved visibility when working with an external suspension. Flight safety has been improved through the use of modern systems to prevent collisions with the ground, other aircraft and obstacles in the helicopter’s route. The Mi-171A2 has the ability to quickly convert – the cargo compartment can be converted into a cargo, search and rescue or passenger version in a short time.
The helicopter was certified in category “A”, which provides for the fulfillment of the most stringent flight safety requirements for civilian helicopters. The vehicle can perform search and rescue, medical, transport operations, extinguish fires or transport passengers at any time of the day, at temperatures from -50 to +50 ° C, in high mountains, desert, tropical or arctic climates. The helicopter is capable of long-term non-stop flights.
