Implicit more prominent numbers than another Russian helicopter, the Mi-8/Mi-17 arrangement (NATO codename "Hip") was outlined essentially as a military transport, yet is likewise in far reaching common utilization.
The Mi-8 was planned as a trade for the cylinder engined Mi-4, with outline work starting in May 1960. To start with flight of the model (controlled by a solitary Soloviev turboshaft driving a four cutting edge fundamental rotor) happened in June 1961, while a creation standard Mi-8 flew in August 1962 and generation started without further ado subsequently. Adaptations of the Mi-8 constructed for common utilization have square windows and incorporate the Mi-8p traveler variant, Mi-8t utility transport, Mi-8tm overhauled traveler transport with climate radar and Mi-8s Salon official transport.
Creation of the Mi-8 stopped for the re-engined Mi-17, which was first freely uncovered to the west at the 1981 Paris Airshow. The Mi-17 presented Tv3 turboshafts and the tail rotor was moved to the port side of the tailboom. Common adaptations incorporate the base Mi-17, and the basically comparable Mi-17-1 and Mi-17m, which both peculiarity all the more compelling Tv3-117vm turboshafts, and are assembled by Ulan Ude Aviation and Kazan Helicopters individually. Both have been heartily showcased in the west.
The Kazan/Mil created Mi-17kf Kittiwake is intended to meet western certificate gauges and peculiarities an EFIS instrument board with shade shows, outlined and incorporated by Kelowna Flightcraft in Canada, adjusted "dolphin" nose with space for radar, and a back stacking incline set up of the clamshell entryways. The recent two peculiarities are likewise consolidated on the Kazan/Mil Mi-17md and Mi-17n.
