The JiaoLian-8 (JL-8) is the domestic version of the K-8 Karakorum basic jet trainer aircraft jointly developed by Nanchang-based Hongdu Aviation Industry Group (HAIG) and Pakistan Aeronautical Complex (PAC). The JL-8 fitted with indigenous turbofan engine and avionics joined the service with the PLAAF in the late 1990s to replace the ageing JJ-5 for basic jet flight training. The K-8 has been exported to many third-world countries and is being locally produced under license in Egypt as K-8E.

教练-8（JL-8）是由南昌建立的洪都航空工业集团（HAIG）和巴基斯坦航空联合体（PAC）共同发展的K-8“卡拉昆仑山”（Karakorum）初级喷气式教练机的国产型。JL-8采用本国涡喷发动机和航空电子设备，在1990年后期进入PLAAF服役去代替陈旧的JJ-5，用于初级喷气飞机飞行训练。K-8已经被出口到许多第三世界国家并且埃及在许可之下本国制造并称为K-8E。

PROGRAMME

China and Pakistan agreed to jointly develop the K-8 Karakorum basic jet trainer in the mid-1980s. The initial plan was to incorporate the aircraft with significant American content, including AlliedSignal (now Honeywell International Inc.) TFE731-2A turbofan engines, and Collins and Magnavox avionics. The development of this project was jeopardized by the US-led sanction following June 1989. Later the K-8 had to switch to the Ukrainian-made AI-25TLK turbofan.

计划

中国和巴基斯坦在1980年中期同意共同地发展K-8 Karakorum初级喷气教练机。最初计划飞机包含采用重要的美国的含量，包括美国AlliedSignal公司（现在霍尼韦尔（Horeywell）国际公司）TFE731-2A涡喷发动机和柯林斯/玛格奈沃克斯航空电子设备。这一个计划的发展在1989年6月之后被美国领导的制裁危及。稍后K-8改成乌克兰制造的AI-25TLK涡喷发动机。

Manufacture of four prototypes started January 1989, and the first flight test took place on 21 November 1990. A total of 14 initial production version planes (six to Pakistani Air Force) were delivered by the end of 1996. However, Pakistan decided against domestic series production of the aircraft in 1994. While the original plan involved up to 75 aircraft for Pakistan, by early 1996 as many as 100 were reportedly desired to replace aging Cessna T-37 trainers.

四架原型的制造在1989年1月启动，而且第一架飞行测试在1990年11月21日进行。总数为14架的初始生产型计划（六架给巴基斯坦空军）在1996年底之前被交付。然而，巴基斯坦在1994年决定生产的飞机不在国内服役。虽然最初的计划涉及达到75架飞机用于巴基斯坦，在1996年初之前，据传闻多达100架预期去代替陈旧Cessna T-37教练机。

The PLAAF version of the K-8, known as JL-8, first flew in December 1994. Six planes powered by AI-25TLK were delivered to the PLAAF in June 1998. The further development variant powered by an indigenous WS-11 turbofan (a Chinese copy of the Ukrainian AI-25TLK) was first tested in December 1998. By the end of 2003 around 100 examples had been delivered to several PLAAF flight schools.

K-8的PLAAF型号，即是JL-8，在1994年12月首先飞行。六架计划采用AI-25TLK提供动力，在1998年6月被交付到PLAAF。在1998年12月由一台本国制造的WS-11发动机（乌克兰AI-25TLK的一种中国仿造型）提供动力的进一步发展型被首次测试。在2003年底之前交付大约100架到一些PLAAF飞行学校服役。

In July 2000 China and Egypt signed a deal of producing 80 K-8s under license. The first Egypt-produced K-8 (known as K-8E) rolled out of the assembly-line in June 2001. In addition, around few dozen K-8s have also been exported to Myanmar, Sri Lanka, Zambia, Namibia, Zimbabwe, and Kenya.

在2000年7月中国和埃及签署了在许可下生产80架K-8的交易。在2001年6月第一架埃及生产的K-8（即是K-8E）在装配线上下线。除此之外，大约不多的12架K-8也已经被出口到缅甸、斯里兰卡、赞比亚、那米比亚、津巴布韦和肯尼亚。

型号

DESIGNS

The JL-8/K-8 has low-mounted wings, lateral air intakes, and whole-piece bubble canopy. Two pilots are accommodated in a tandem, air-conditioned cockpit, with the back seat slightly higher than the front seat. The domestic JL-8 differs from the export variant K-8 in avionics configuration and power plant.

设计

 JL-8/K-8采用下单翼，侧进气口和整块汽泡式座舱罩。 二名驾驶员容纳在串联式座位内，装有空调冷气的驾驶座舱中，后座稍微较高于前座。国内的JL-8和外销型K-8的不同之处在航空电子设备配置和发动机。

WEAPONS

The JL-8/K-8 doesn't have a fixed weapon. There are four under-wing pylons to carry up to 1,000kg payload, each rated at 250kg. The stations can carry drop tanks, 23mm cannon pods, unguided rockets, 250kg bombs, short-range air-to-air missiles (e.g. Magic R550).

武器

JL-8/K-8没有一种固定武器。有四个机翼下挂架用于最大携带1,000公斤负载，每个额定250公斤。挂点能携带副油箱，23毫米机炮吊舱，非制导火箭，250公斤炸弹，近程空对空导弹（举例来说“魔术”R550）。
