Chinese defence firm China Aerospace Science and Technology Corporation (CASC) has incorporated a number of enhancements to its Cai Hong 4 (Rainbow 4, or CH-4) unmanned aerial vehicle (UAV) that are now fully validated and available as options in its export product portfolio, Jane's has learned during a demonstration in northwest China in late July.

中国防务公司中国航天科技集团公司（CASC）对其彩虹-4型（Rainbow 4或CH-4）无人机（UAV）进行了一系列改进，目前已经完全验证并可作为出口产品选项组合中，简氏在7月下旬中国西北地区的示范活动中获悉。

 

The CH-4 is a medium-altitude long-endurance (MALE)-class, strike-capable reconnaissance platform that has been developed by the China Academy of Aerospace Aerodynamics (CAAA), and is in service with a number of military forces in Central Asia and the Middle East.

CH-4型是由中国航天空气动力技术研究院（CAAA）开发的中高空长航时（MALE）级别，攻击能力侦察平台，并且一定数量的无人机已在亚洲中部和中东的一些军事力量中服役。

 

According to the latest official specifications provided by CAAA, the CH-4 has a maximum take-off weight of 1,330 kg and a payload capacity of 345 kg. Glass fibre-based composite materials are used extensively to construct the 8.5 m-long main body and 18 m span wings, reducing the overall weight of the air vehicle as well as its radar cross-section (RCS).

根据CAAA提供的最新官方规格，CH-4最大起飞重量为1330公斤，载重量为345公斤。玻璃纤维复合材料广泛用于构建8.5米长的主机身和18米翼展机翼，减少了飞行器的总体重量以及雷达横截面（RCS）。

 

Jane's understands that the CH-4 is presently powered by a 100 hp-class piston engine, which drives a three-bladed variable pitch pusher propeller and enables the air vehicle to achieve cruise and maximum speeds of up to 180 km/h and 235 km/h respectively, with a maximum endurance of up to 40 hours. It typically performs its missions at altitudes of 3,000–5,000 m (9,842–19,685 ft), although it is capable of operating up to a service ceiling of 7,200 m.

据简氏的了解，CH-4型目前由一台100马力的活塞式发动机提供动力，这种发动机驱动了三浆叶可变桨距推进器，使得飞行器在空中能够实现高达180公里/小时巡航速度和235公里/小时的最大速度，续航力最长可达40小时。它通常在3000-5000米（9,842至19685英尺）的高度执行其任务，尽管其能够在达到7200米升限操作。
