Harbin Aircraft Manufacture Corporation (HAMC) began to develop an attack helicopter based on the Zhi-9 army utility helicopter in the mid-1980s. The attack helicopter, designated Zhi-9W (Z-9W), features a pair of external weapon pylon and a roof-mounted optical sight for target searching and tracking in daylight. The helicopter was mainly intended for anti-armour warfare role, carrying four HJ-8 wire-guided anti-tank missiles. Alternatively, the helicopter could carry guided rocket pods or machine gun pods for close air support role. A total of 30~40 examples in the basic Z-9W variant have been built and these helicopters are serving with the 8th Helicopter Regiment organic to the 38th Group Army.

哈尔滨飞机制造公司(HAMC)在1980年中期开始发展基于直-9陆军通用直升飞机的一种攻击型直升飞机。攻击直升飞机指定为直-9W(Z-9W),特征是一对外部挂架和一套顶部安装瞄准具用于昼间目标搜索和跟踪。直升飞机主要准备用于反装甲战斗任务,携带四枚HJ-8线导反坦克导弹。二者择一地,直升飞机可以为近距离空中支援任务携带制导火箭吊舱或机炮吊舱。基本Z-9W型已经被制造的总数为30~40架,而且这些直升飞机正在第38集团军隶属的第8直升飞机团服役。

In 2005, HAMC introduced an improved “night attack variant”, also known as Z-9WA. The most notable improvement was an under-nose observing and tracking unit housing a low-light TV and an infrared search and track (IRST), allowing the helicopter to operate in all-weather, day/night conditions. Other improvements included redesigned weapon pylons similar to those of the French AS 565 Panther, a self-defence electronic warfare suite, a new cockpit with multi-function displays (MFD), and possibly two more powerful Turbomeca Arriel 2C turboshaft engines. A second variant designated Z-9WE is in service with the PLA Air Force for security and counter-terrorism role.

在2005年,HAMC推出一种改进“夜间攻击改型”,也即是Z-9WA。最值得关注的进步是机鼻下观察和跟踪单元容纳了下视TV和一套红外搜索和跟踪(IRST)系统, 允许直升飞机全天候、昼/夜状况下操作。其它的进步包括重新设计武器挂架类似法国AS 565“美洲豹”的那些,自卫电子战组件和一个新型采用多功能显示器(MFD)的驾驶员座舱,并可能二台功率更大的透博梅卡公司Arriel 2C涡轴发动机。一种被指定为Z-9 WE的第二种改型是用于安全和反恐任务并在PLA空军中服役。

Design

The construction of the Z-9W is similar to that of the Z-9B army utility helicopter. The helicopter is of light aluminium alloy construction with glass fibre reinforced plastic and Nomex for added strength and for weight reduction. The helicopter is lightly armoured, with no apparent IR reduction features. The teardrop-shaped body features a tapered boom to the tail fin, a rounded nose and stepped-up cockpit. Two weapon pylons are attached to the fuselage behind the pilot seats.

设计

Z-9W的构造与Z-9B陆军通用型直升飞机相似。直升飞机采用轻铝合金结构和玻璃纤维强化玻璃钢和Nomex用于增加强度和减轻重量。直升飞机轻型装甲,同时没有明显的IR减少特征。水滴形特征机身一个渐缩尾梁到尾翼,一个圆形前鼻和阶梯式驾驶员座舱。二个武器挂架安装在飞行员座位后面的机身上。

The tail flats feature swept-back tips forward of the swept-back and tapered fin with a blunt tip. The Z-9B variant features a modified 11-blade Fenestron faired-in tail rotor with wider-chord, all-composite blades instead of 13 all-metal blades as in AS 365N1.

尾平翼特征是顶端有一个上端后掠的垂直安定翼和锥形尾垂翼具有一个钝形顶端。Z-9B改型特点是改进的11-浆叶涵道减阻内置尾螺旋桨,采用宽-弦、全-复合浆叶而不是像在AS 365N1型上的13-浆叶全金属浆叶。

The helicopter has hydraulically-operated retractable tricycle type landing gear. The nose unit is twin-wheeled and retracts rearward. The main units are single-wheeled and retract into wheel troughs in the fuselage. All three units of the land gear are equipped with oleopneumatic shock absorbers.

直升飞机采用液压操可收放前三点起落架。前鼻下单元是双轮并且向后收回。主单元是单轮收回到机身下的轮槽中。全部三个起落架单元安装双腔油气减震器。

Avioncis

The helicopter’s cockpit can be fitted with a BG-06 radio altimeter, Type 150 single-sideband radio, and KJ-13 autopilot, and can choose the KDF-806 radio compass, KTR-908 radio, and TB-31 intercom as optional.

航空系统

直升飞机的驾驶员座舱能够配备有一部BG-06型无线电测高计、150型单波段无线电和KJ-13型自动驾驶仪,并可选KDF-806型无线电罗盘、KTR-908型无线电和TB-31型对讲器。

The improved Z-9WA is fitted with an electronic countermeasures suite consisting of a missile approach warning system and chaff/flare decoy dispensers. The system can detect infrared signature of incoming missiles, alert the pilot and automatically trigger the chaff/flare dispensers to counter the threat.

改进的Z-9 WA配备有一套电子对策组件由导弹接近告警系统和箔条/闪光诱饵布撒器所组成。系统能发觉入射导弹红外线信号,提醒飞行员和自动地启动金属箔条和红外诱饵曳光弹撒布器去对抗威胁。

Fire-Control

Early basic variant Z-9W has an optical sight unit mounted on the roof of the cockpit directly above the weapon operator. The unit is used to search for targets and guide the HJ-8 missile in a semi-automatic command line of sight (SACLOS) mode. The weapon operator aims at the target through X12 sight of TV goniometry, and keeps the cross hairs of the sight on the target until the missile hits the target.

火-控系统

早期基本Z-9W型有一套瞄准单元安装在驾驶员座舱顶部直接在武器操作员上方。单元用于HJ-8导弹在瞄准线半自动控制(SACLOS))模式下瞄准和制导。武器操作员通过X12型TV瞄准具测角仪瞄准目标,而且保持瞄准器的交叉瞄准线在目标上直到导弹击中目标。

The improved Z-9WA has an under-nose observing and tracking unit developed by Luoyang Electro-Optics Technology Development Centre (EOTDC). The unit comprises a low-light TV and an infrared search and track (IRST), which enables the missile to engage target in all-weather, day/night conditions.

改进的Z-9WA型有一套机鼻下观察和跟踪单元,由洛阳光电技术发展中心(EOTDC)开发。单元包括下视TV和一套红外线搜索和跟踪(IRST)系统,使导弹能在全天候、昼/夜状况下同目标交战。

Weapons

The helicopter has a pair of weapon pylons to carry 4 (or 8 on the Z-9WA) HJ-8 wire-guided anti-tank missiles. Alternatively, the helicopter can carry two 12.7mm machine gun pods, or two 57mm or 90mm unguided rocket pods, or four TY-90 IR-homing air-to-air missiles (6km range).

武器

直升飞机有一对武器挂架携带4枚(或在Z-9WA上8枚)HJ-8线导反坦克导弹。二者择一地,直升飞机能携带双12.7毫米机枪吊舱,或二具57毫米或90毫米非制导火箭吊舱,或四枚TY-90型红外制导空对空导弹(6公里射程)。

Engines

The Z-9B is powered by two 550kW (739hp) Turbomeca Arriel-IC1 turboshaft, which is produced by SAEC at Zhuzhou as Wozhou-8A (WZ-8A). The fuel capacity is 1,140 litre, with option for a 400 litre ferry tank.

发动机

Z-9B动力由二台550千瓦(739马力)透博梅卡公司Arriel-IC1涡轴发动机提供,由位于株洲的SAEC生产称为涡轴-8A(WZ-8A)。燃料能力1,140升,连同一个400公升油囊选项。
