The Changhe Z-18 is a medium-lift transport helicopter developed by Changhe Aircraft Industries Corporation (CAIC) to replace the Harbin Z-8.

Design and development[]

The Z-18 is a development of the Avicopter AC313 and Harbin Z-8, both of which are developments of the Aérospatiale SA 321 Super Frelon.[2][1]

The fuselage reportedly makes greater use of titanium and composites,[3] and replaces the Z-8's boat-shaped lower fuselage with a tail ramp for small vehicles.[1] It has a glass cockpit[2] and is powered by three WZ-6C turboshafts.[2][1]

The Z-18's maximum takeoff weight (MTOW) is 13.8 tonnes. In late-2014, the only People's Liberation Army Navy (PLAN) ships able to operate the helicopter at MTOW were aircraft carriers and large amphibious assault ships.[3]

Operational history[]

The Z-18F anti-submarine warfare (ASW) version was undergoing testing by the end of August 2014.[3]

The transport Z-18A first appeared in Chinese state media in December 2014, and reportedly underwent high-altitude testing on the Tibetan Plateau in January 2015.[2] The Z-18A reached an altitude of 9,000 m (29,528 ft) during testing.[1]

The Z-18A was in service with the People's Liberation Army Ground Force (PLAGF) by January 2018.[2]

Variants[]

  • Z-18A: Transport variant. It may carry 27[2]-30 troops,[1] small vehicles, or 5 tonnes of cargo to a range of up to 1000 km.[1] An extended nose contains terrain-following radar and an electro-optical system.[2] Some have a SATCOM fairing on the tailboom. The variant may have been re-designated as Z-8G (Gaoyuan, or "Plateau").[1]
  • Z-18F: ASW variant with chin-mounted surface search radar, dipping sonar, and may be equipped with up to four lightweight torpedoes and 32 sonobuoys.[3]
  • Z-18J: Airborne early warning (AEW) variant, with a lowerable radar antenna in place of the ramp.[3]
