China's unmanned helicopters pass high-plateau testing/中国的无人直升机通过了高原测试
The AV500W conducts firing tests at an altitude of 4,300 meters in Qinghai province on Nov 18, 2017.
NANCHANG -- Three unmanned helicopters made test flights recently on the Qinghai-Tibet Plateau, authorities said Thursday.
The AV500W conducted firing tests at an altitude of 4,300 meters in Qinghai province on Nov 18, according to Jiangxi provincial office of science, technology and industry for national defence.
At 4,600 meters above sea level, on Nov 9, XM20 multi-rotor drone took off and landed with a full payload.
The AV500 climbed to an altitude of 5,006 meters during tests on Oct 31, the maximum achieved by a domestically-made unmanned helicopter.
The three have applications in counter-terrorism, drug policing, border patrols, meteorology and mapping.
The aircraft were developed by a helicopter research and development institute in Jingdezhen, Jiangxi province, owned by the Aviation Industry Corporation of China.
The institute began work on unmanned helicopters in 2004.

南昌 - 有关当局今天表示，三架无人直升机最近在青藏高原进行试飞。
根据江西省国防科技工业办公室的资料，AV500W于11月18日在青海省海拔4300米处进行了射击试验。
11月9日，海拔4600米的XM20多旋翼无人机起飞降落，满载。
10月31日，AV500的测试高度达到了5006米，这是国产无人直升机的最高水平。
这三者在反恐，毒品治安，边防巡逻，气象和制图方面有应用。
这架飞机是由中国航空工业集团公司所属的江西省景德镇直升机研究开发机构研制的。
该研究所于2004年开始研制无人直升机。
