China has developed a new military transport helicopter Z-18.
The Changhe Z-18 is a medium transport helicopter developed by Changhe Aircraft Industries Corporation (CAIC) to replace the Z-8.
The Z-18 is a single-rotor helicopter with tail rotor and a non-retractable landing gear, thought to be based on the Avicopter AC313, an updated design based on the earlier Harbin Z-8, itself a development of the Aérospatiale Super Frelon.
Naval version of Z-18 was first revealed onboard Chinese aircraft carrier Liaoning. In 2014, army version of Z-18 was revealed in Chinese army publications. It features a redesigned lower fuselage, with power provided by three improved WZ-6 turboshaft engines and has a maximum payload of 13.8 tonnes.
