The Mi-17 helicopter, developed at the Mil Design Bureau from the Mi-8 helicopter, is in serial manufactured at the Kazan Helicopter Production Association. The designation Mi-17 is for export; the Russian armed forces called it Mi-8MT. The Mi-17 can be recognized because it has the tail rotor at the starboard side, instead of the port side. The Mi-17 added a number of improvements to its predecessor, including a vibration damper to increase comfort for crew members and passengers. The helicopter features a high thrust-to-weight ratio pair of TVZ-117MT or TVZ-117VM shaft-turbine engines with a takeoff power of 1,900 hp. The Mi-17 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 engines output is automatically increased to allow continued flight.
