"Russian Helicopters Group is planning to certify the Mi-171A2 medium-class multipurpose helicopter in the first quarter of 2017," the press office added.

According to the press office, two prototype Mi-171A2 helicopters are taking part in the certification trials. The first Mi-171A2 helicopter performed its debut flight in November 2014 and the second chopper took to the skies in October 2015. Trials with the use of a flying laboratory developed on the basis of the serial Mi-8/17 helicopter were held simultaneously.

The third and the fourth Mi-171A2 helicopter prototypes did not undergo trials as they are bench-scale models. The fifth Mi-171A2 helicopter prototype has already been dispatched to the Mil Moscow Helicopter Plant. The Mi-171A2 helicopter is the advanced rotorcraft in the Mi-8/17 (NATO reporting name: Hip) family.

The helicopter is equipped with an integrated digital attitude and heading reference system of the KBO-17 avionics suite. The KBO-17 avionics suite has a glass cockpit design to allow operating the helicopter without an engineer onboard. Thus, the helicopter’s crew may be reduced to two.

The Mi-171A2 helicopter has the main and the X-type anti-torque rotors made of composite materials, as well as an improved swashplate and a hub.

The upgrade has allowed increasing the helicopter’s controllability, reducing the weight of its rotor system and enhancing the main rotor thrust by 700 kilograms.
