More details emerge about China's Z-20 helicopter

Chinese state-owned media have released more details about the Z-20 helicopter operated by the People’s Liberation Army Ground Force (PLAGF).

Reports by the Global Times newspaper highlighted that the engines installed in the Z-20 provide sufficient power for the aircraft to perform well at high altitudes, and stated that the Z-20 design incorporates “many technologies that should be considered advanced in the world, including active vibration control, fly-by-wire, low-noise design for rotor and the high-performance aerodynamic design of the rotor”.

The reports, which were published in the context of the fifth biennial China Helicopter Exposition held in Tianjin from 10–13 October – where the Z-20 was a key exhibit – followed the first public appearance of the Z-20 at China’s National Day Parade on 1 October.

A 1,600 kW turboshaft engine displayed at the Tianjin exhibition is believed to be the type that powers the twin-engined Z-20. A display board accompanying the exhibited engine noted that it is suitable for medium and large helicopters. No designation was given to this engine, although it is thought to be the WZ-10.

The performance of the engine, which is claimed to have been developed independently, is reportedly comparable with those produced by leading international manufacturers.

No further information was released about the active vibration control system, nor the rotor design features. Images indicate that a de-icing system is integrated into the main rotor blades, which will enhance the helicopter’s all-weather capabilities.
