Harbin/CHDRI Z-6, (Z – Zhishengji – flygplan med vertikal start), är en kinesisk helikopter baserad på Harbin Z-5, som i sig är en licensbyggd Mil Mi-4. En begränsad produktionsserie avbröts efter att prestandan visade sig vara sämre än dess föregångare Z-5

General Characteristics and Role

The Harbin Z-6 (Zhi-6) was a Chinese military transport helicopter developed by the Harbin Aircraft Manufacturing Corporation (HAMC) and the Chinese Helicopter Design Research Institute (CHDRI). It was a significant project as it was China’s first domestically developed turboshaft-powered helicopter, intended to replace the piston-engine Harbin Z-5 (a license-built Mil Mi-4). The Z-6 design retained the general size and fixed quadricycle landing gear of the Z-5 but featured a new, wider fuselage and a single turboshaft engine mounted above the cabin. Development was plagued by technical issues (including excessive vibration and engine overheating) and political turmoil, leading to a fatal crash in 1972. Despite receiving type approval in 1977, only about 11 prototypes/pre-production units were built before the program was terminated, as the single-engine design was deemed unsafe and its performance inferior to the Z-5 it was meant to supersede.

Development and Legacy

Basis: Designed as a turboshaft-powered upgrade to the Z-5 (Mil Mi-4).
Production: Extremely limited; only around 11 airframes were constructed due to performance and safety concerns.
Status: The program was effectively canceled in the early 1970s, and the Z-6 saw only brief, limited service before being retired by 1980.
Significance: Despite its failure, the Z-6 provided valuable experience in designing and integrating turboshaft engines into helicopters, paving the way for future Chinese helicopter development.
