The Harbin Z-9 (NATO reporting name "Haitun", Chinese: 海豚 for Dolphin) is a Chinese military utility helicopter with civilian variants. It is a licensed variant of the French Eurocopter AS365 Dauphin, and is manufactured by Harbin Aircraft Manufacturing Corporation.
Design and development
The first Z-9 flew in 1981, and was built in China from components supplied by Aérospatiale as part of a production patent bought on 15 October 1980. On 16 January 1992, the indigenous variant Z-9B, constructed with 70% Chinese-made parts, flew successfully. The flight test was completed in November 1992 and the design was finalized a month later. Z-9B production began in 1993 and entered PLA service in 1994.
The Z-9B features an 11-blade Fenestron faired-in tail rotor with wider-chord, all-composite blades replacing the 13-blade used in the original AS365N. As a light tactical troop transport, the Z-9 has the capacity to transport 10 fully armed soldiers. Generally the Z-9 is identical to the AS365N Dauphin, though later variants of the Z-9 incorporate more composite materials to increase structural strength and lower radar signature.
The helicopter has a four-blade main rotor, with two turboshaft engines mounted side by side on top of the cabin with engine layout identical to the AS365N. The Z-9 teardrop-shaped body features a tapered boom to the tail fin, with rounded nose and stepped-up cockpit, retractable gear, and all flat bottom.
In 2002, Harbin obtained Chinese certification for the new H410A variant of the Z-9, which features more powerful Turbomeca Arriel 2C turboshaft engines; Eurocopter issued official objections to Harbin's decision to continue production in spite of the license-production agreement having expired, leading to a period of highly sensitive international negotiations to resolve the dispute.
An armed variant has been fielded by the PLA since the early 1990s as the WZ-9 or Z-9W, with pylons fitted for anti-tank missiles. These helicopters lack the maneuverability and survivability of a proper attack helicopter, and merely provide a stopgap during the development of the WZ-10. The latest armed version, the Z-9W, was introduced in 2005 and has night attack capabilities, with an under-nose low-light TV and infra-red observing and tracking unit.
The naval version introduced in the 1990s is known as the Z-9C. As well as SAR and ASW duties, the Z-9C can be fitted with an X-band KLC-1 surface search radar to detect surface targets beyond the range of shipborne radar systems.

- A newer night-capable version has been built with nose-mounted FLIR. July 2011, Xinhua News Agency released a photo of Z-9WA firing AKD10 air-to-ground missile. Incorporates a domestic Chinese helmet mounted sight that is compatible with anti-tank missiles such as HJ-8/9/10, as well as light anti-ship missiles such as C-701/703 and TL-1/10 when they are used as air-to-surface missiles, air-to-air missiles such as TY-90 and other MANPAD missiles for self-defense.
