The Harbin Z-5, produced by the Harbin Aircraft Industry Group, is a versatile helicopter that is a licensed replica of the Soviet Mi-4 helicopter. The development of the Harbin Z-5 began in February 1958, with its first test flight taking place in December of the same year. However, due to the rushed development process, all Z-5s produced between 1958 and 1960 did not meet the required standards and were not accepted for military service. It was not until 1963 that mass production of the Z-5 officially commenced. Despite being a licensed replica of the Mi-4, there are notable differences between the two helicopters. The Mi-4 utilized a wood and steel structure for its rotor and helicopter blades, whereas the Chinese Z-5 employed a fully steel structure. This modification significantly enhanced the performance, durability, and structural integrity of the Z-5’s blades. Additionally, after 1966, the Z-5 incorporated back rotor blades made of Fiber Reinforced Plastic, further improving the helicopter’s maneuverability and agility. Similar to the Soviet Mi-4, the Harbin Z-5 initially served as a transport helicopter but also featured an armed variant, akin to the Soviet modification of the Mi-4. Currently, all Z-5 helicopters, regardless of their purpose, have been retired from active service.
