UAVs about to have a new 750kg thrust turbofan
陕西炼石有色资源股份有限公司关于750公斤推力发动机完成高空台性能测试的公告
中国证券报 8小时前
证券代码：000697 证券简称：炼石有色 公告编号：2018-047
本公司及董事会全体成员保证信息披露的内容真实、准确、完整，没有虚假记载、误导性陈述或者重大遗漏。
陕西炼石有色资源股份有限公司接到中国科学院工程热物理研究所和公司参股公司成都中科航空发动机有限公司(以下简称“中科航发”)的通知，由中科航发研制的750公斤推力等级中等涵道比涡扇发动机，继2017年顺利完成60小时持久性能试车考核后，在俄罗斯中央航空发动机研究院（简称“CIAM”）完成了高空台性能测试工作。
在此轮高空台性能试验中，该款发动机圆满地完成了涵盖10000～15000米飞行高度、0.4～0.8马赫数速度范围内典型工况的性能测试工作，并进行了18000米发动机性能摸底测试试验。
该款涡扇发动机在先后顺利完成地面60小时持久性能试验和高空台性能测试之后，已经具备了首飞条件。该型发动机的研制成功，填补了国内该推力等级涡扇发动机的空白。其在军用高空、高速和长航时无人机及民用小型行政机方面，具有良好的市场前景。
注：俄罗斯中央航空发动机研究院成立于1930年，是俄罗斯唯一一家致力于航空发动机综合研究和发展的研究单位，也是俄罗斯最大的航空发动机试验中心。目前已成为欧洲最大的航空发动机试验基地。CIAM具有多年的航空发动机高空试验经验，其高空试验平台可模拟0～27km高度和0～4马赫数范围的飞行条件。
特此公告。

Chinese leading drone makers set to serve police-use UAVs

It’s time to test China’s flourishing drone manufacturers and their promotion lines. How reliable are they? Can they really stand strong wind and avoid obstacles?
The fierce market competition among Chinese drone makers has turned into a war of sorts, as more and more Chinese police start to adopt the technology.
“Police-use drones have witnessed huge growth in recent years. In 2015, the number of police-use drones was a mere 500, whereas the number exceeded 5,000 two years later,” announced Sun Yongsheng, director of China Low-Altitude Security Research Center, at a forum during the 8th China UAS Conference & Exhibition in Beijing on Friday.
The number may appear small when compared to the 3 million drones sold in China, where hundreds of companies are churning out the flying machines and some 50,000 people are licensed to operate them.
Jin Wei, deputy secretary general of China UAS Industry Innovation Alliance, also revealed at the forum that China’s drone industry has reached an output value of 23 billion yuan in 2017 and achieved a growth rate of 67%.
This rapid growth provides a sound foundation for police-use drones that can make full use of the nation’s advantage in those hovering cameras, Sun noted.
For example, Chinese drone maker Zerotech, a supplier of police-use drones, presented at the forum its hybrid drones with both fixed wings and multiple rotors, which are faster and more reliable and can fly longer. The hybrid design also guarantees that the drones will not crash in case of power loss, because the fixed-wing design allows them to safely glide.
“The most appropriate height for police-use drones is between 120-300 meters, which makes pure rotor drones inadequate. Given their stealthy way of action up in the air, they could replace police in key patrol areas or for reconnaissance missions in dangerous situations. They could also help with lengthy stakeouts or tracking,” Yang Jianjun, founder and CEO of Chinese drone maker Zerotech, introduced.
With zoom cameras, drones for stakeouts or tracking could also be used to capture the appearance of the target while reducing the risk of compromising the police presence.
Currently, China Low-Altitude Security Research Center has inked a cooperation agreement with the publishing house of People’s Public Security University of China on applied drone courses. It is also coopering with the Ministry of Public Security in offering drone flying training programs, according to Sun.
