China Releases New Details on the AVIC Z-20 Helicopter
China’s state-owned newspaper, the Global Times, published a number of details about the Z-20, which is the People’s Liberation Army’s (PLA) new transport helicopter, following the Z-20’s official public debut at China’s National Day parade on 01 October 2019.
The Z-20 is a twin-engine medium-lift helicopter with a maximum take-off weight (MTOW) similar to that of the S-70i Black Hawk helicopter, i.e., in the 9-11-ton range.
In an interview with the Global Times, Wang Xibao, the chief engineer at Harbin Aircraft Industry Group – i.e., a subsidiary under the Aviation Industry Corporation of China (AVIC) – stated that the Z-20 “uses many technologies that should be considered advanced in the world.”
These include, among others, “active vibration control, fly-by-wire, low-noise design for rotor and high-performance aerodynamic design of the rotor.”
To AVIC’s credit, fly-by-wire is not a common flight control system for helicopters. In fact, Sikorsky is only experimenting fly-by-wire on the UH-60A at this time.
Moreover, the Z-20 is operable in a diverse range of environments, include high-altitude areas with a lack of oxygen. The helicopter’s designers credit this capability to the Z-20’s indigenous turboshaft engines.
Finally, the Z-20 employs a glass cockpit consisting of multi-function displays (MFD).
Notes & Comments
Given that the Z-20 is likely in the weight-class of the S-70, NH-90 and AW149, it is likely that it is capable of transporting 14-20 troops. It might have an external payload (via slung) of roughly 3,000 kg to 4,000 kg.
It will be interesting to see how the Z-20 fares in the export market. AVIC would offer prospective buyers a modern platform with analogous technologies and capabilities to Western platforms, such as the S-70i and NH-90, but potentially at a more competitive cost. With a potential scope of replacing hundreds of Z-9 and Mi-8/17 helicopters across each of the PLA’s service arms, the Z-20 will draw on economies-of-scale.
In addition, the introduction of the Z-20 – and certification of its engine – could also give China the basis of a next-generation heavy attack helicopter.
