The Harbin Z-5 (''Zhishengji'' - helicopter) is a Chinese copy of the Soviet Mil Mi-4 piston engined helicopter. It was produced in the city of Harbin, China. The USSR provided China with blueprints in 1958, a few years before the Sino-Soviet split. The first flight was in 1959, but serial production was delayed and did not start until the mid-1960s. China has produced a number of unique variants, and the Z-5 was in use with the PLA, PLAAF and PLANAF in large numbers, although it might still be in reserve.〔Source: http://www.sinodefence.com/airforce/aircraft.asp〕 China also exported a number of Z-5 to client states. About 545 were built.〔Source: http://www.globalsecurity.org/military/world/russia/mi-4.htm〕 A few Z-5 helicopters were modified to carry machine-guns and rocket pods.〔(【引用サイトリンク】title=AirForceWorld.com Z5 Helicopter Armed Version )〕 One Z-5 was reengined with a Pratt & Whitney Canada PT6T-6 "Twin Pac" turboshaft in 1979, during the Chinese-Western rapprochement. Some sources refer to this as the Z-6, but the experiment went no further.〔Source: www.vectorsite.net by Greg Goebel (public domain)〕 ==Variants== ;Z-5 : Military transport helicopter. ;Z-5 assault helicopter: Some Z-5 were converted to carry rocket pods on outriggers in addition to a gondola with a forward firing machine gun manned by the Flight engineer. ;Z-5 Xuanfeng : Civil transport helicopter. ;Z-5 VIP helicopter:VIP versions distinguishable by larger rectangular windows in the cabin. ;Z-5 agricultural helicopter: Some Z-5s were fitted with chemical hoppers and/or spray gear for agricultural or forestry protection use. ;Z-5 SAR helicopter:Thirteen z-5s are known to have been converted to SAR helicopters with a winch and external fuel tanks. ;Harbin/CHDRI Z-6 : A turboshaft variant of the Z-5, eleven aircraft built. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Harbin Z-5」の詳細全文を読む スポンサード リンク
