KA-27 Helix A
Ka-27 was designed to replace Ka-25. The first prototype flew in December 1974. Variants include the Ka-27PS search and rescue version and Ka-28 ASW model.
The KA-27 helicopter is intended to be used for search-rescue provision of aircraft flights over the sea and the land, and also for provision of emergency-rescue operations at the disasters of ships and vessels, at day and night time, in simple and complicated weather conditions at the sea roughness up to 5 number, alone and in combination with ships. To carry out rescue operations, the helicopter is equipped with the winch with lifting capacity 300 kg.
The flight-navigation complex of the helicopter allows to conduct an automatically controlled flight of the helicopter according to the pre-set route, a landing of the helicopter on deck a ship and an unloading of the ship without the stoppage of the latter, an autonomous hovering of the helicopter over the pre-determined point, and together with the radar “Osminog”, leading out of the helicopter into the point of the flight pre-set by the pilot.
The helicopter is fitted with the inflatable ballonnet system which ensures the floatage of the helicopter in case of its emergency landing on the water surface. The blade folding mechanism allows to considerably diminish the overall dimensions of the helicopter at its storage in the hangars of the ships and aerodromes.
