The Aviation Industry Corporation of China (AVIC) is pursuing a solar-electric, long-endurance unmanned aerial vehicle (UAV) development programme called Qi Mingxing (Venus), Chinese aviation news portal CAN News reported in late July.
中国航空工业集团有限公司(AVIC)正在推行一项太阳能、长航时无人机(UAV)发展计划称为“启明星”(Venus ), 中国航空新闻门户网站CAN News在七月下旬报道。
 
According to the report, AVIC’s First Aircraft Institute has partnered with carbon fibre and composites manufacturer Jiangsu Hengshen to complete assembly of a prototype with a 20 m wingspan.
依照报道,中航工业第一飞机设计研究院(603所)已经与碳纤维和复合材料制造厂商江苏恒神公司合作完成一架20米翼展的原型装配。
 
The prototype is understood to have entered production at the end of 2017 and to have been completed on 15 July. It also reportedly features a composite structure with all-weather flight capability, with the main wing structure having a chord length of 1.1 m and a weight of 18.9 kg.
原型据了解在2017年底进入生产在今年7月15日已经完成。据报道它还具有全天候飞行能力的复合结构为特点,主翼结构弦长为1.1米和重量为18.9 公斤。
 
The company is expected to begin ground-based electrical and mechanical testing in anticipation of its maiden flight.
公司预计将会为它的首飞开始地面电气和机械测试。
 
Official details of the Venus development remain unknown, although a conceptual model of the envisioned final product – an air vehicle with a wingspan of 50 m and an overall fuselage length of 21 m – was shown at Airshow China 2016. An AVIC spokesperson told Jane’s then that the company was committed to pursuing its development.
关于“启明星”发展的官方细节仍然未知,虽然一个想像的最终产品概念模型-一架具有50米长翼展和全部机身长度21米的飞行器-在2016年中国国际航空航天博览会(珠海航展)被展示。一位中国航空工业集团有限公司(AVIC)发言人当时告诉简氏公司致力于追求它的发展。
 
The concept shown at Airshow China 2016 depicted an airframe with a main fuselage pod that supports a shoulder-mounted wing and a cruciform tail assembly. According to company-supplied specifications, the air vehicle will be propelled by four electric tractor motors that draw power from fuel cells that are recharged via solar cells covering the upper section of the entire fuselage and wing, providing a projected cruising speed of 100–125 km/h and endurance of more than 30 days.
在2016年中国国际航空航天博览会(珠海航展)上的概念展示描述一个主机身舱去支撑肩部安装的机翼和一个十字形尾翼组件。依照公司提供的规格,飞行器将会被四台电动机驱动,这些电动机通过覆盖在全部机身和机翼上部的太阳能充电的燃料电池提供动力、预计巡航速度100-125公里/小时和长达 30 天的续飞力。


“启明星”无人机规格
 
Besides AVIC, the China Academy of Aerospace Aerodynamics (CAAA) – a subsidiary of defence prime China Aerospace Science and Technology Corporation (CASC) – is also pursuing an unmanned solar-electric platform under the development name of the Cai Hong (CH) Solar UAV.
除中国航空工业集团有限公司(AVIC)之外,中国航天空气动力技术研究院(CAAA)- 一个国防主要的中国航天科技集团有限公司 (CASC)附属公司 - 也正在开发一种命名为彩虹(CH)太阳能无人飞机(UAV)的一个无人操纵太阳能动力平台。

一飞院的“启明星”无人机,是首个展示的该系列无人机的型号。

该机的翼展20米大型机翼,弦长1.1米,有多处承力接头,但仅仅重18.9公斤。一个人就能轻松拿起整一个巨大机翼。

据称,“启明星”的20米翼展型号,是采用复合材料结构的太阳能无人机,大面积覆盖太阳能电池作为动力来源,可进行超长航时全天候飞行,在环境监测、局部通信、海事活动等领域有着非常巨大的市场前景。

据称该机飞行高度20000米,飞行速度接近130公里/小时。其覆有太阳能电池板的大机翼和机身。预计该机使用4台螺旋桨电动机,能够保证实现大于30天的惊人巡航能力。
