From VOA Learning English, this is the Technology Report.
 
The Federal Aviation Administration, or FAA, has chosen a university town in Virginia as one of six places to test drones. Drones are aircraft without human pilots. A drone can also be called an unmanned aircraft system, or UAS. The town, Blacksburg, is home to Virginia Tech University.
 
The university has flown and researched unmanned aircraft systems for years. But now, the research has more meaning. Researchers at Virginia Tech send reports to the FAA to assist the agency in the development of national drone rules. The FAA says most business drones cannot operate legally now. The agency plans to announce rules for how drones can share airspace in the United States with major airplane companies.
 
The leader of the Blacksburg test center is Rose Mooney. She says that her researchers are doing new things with UAS.
 
"UAS can do things that manned aircraft can't. Our first flight is going to be a larger aircraft that hasn't been flown unmanned in the national airspace."
 
Air information sensors are common on manned airplanes. But researchers at the Virginia Tech University test center have added a sensor to their drones. The sensor records air speed and altitude, the height of the flight. The information is sent through tubes to a computer that examines stability. All of the information is then sent to the FAA.
 
The federal agency may also rule on another device to guarantee greater safety. The device is a special eyewear that lets a person see the flight as if he or she is on the drone. Pilots on the ground can use this view to better direct the drone and keep it away from objects in the flight path.
 
Researcher Justin Stiltner says drones can be used to do jobs that are uninteresting, dirty or dangerous. They can fly into areas of radiation, or inside hurricanes or over croplands to examine corn. Professor Craig Woosley says farm studies are the main goal.
 
"We need to do better at how we do agriculture so we can continue to improve crop yields and that drives us toward ever more and more technology. "
 
Rose Mooney thinks using drones is a huge step forward in the flight industry. But drone use will not change until the FAA publishes new rules. And that is not expected to happen until late 2015.

美国联邦航空管理局,简称FAA,选择了弗吉尼亚州的一个大学城来作为测试无人机的地点。测试地点一共六处,这是其中一处。无人机是指没有飞行员操纵的飞机,也可被称为无人飞行系统或者UAS。试验基地Blacksburg,是弗吉尼亚理工大学所在的小镇。
 
弗吉尼亚理工大学进行了多年的飞行和研究。但如今,研究有了更多的意义。该校的研究者向美国联邦航空管理局提出报告以帮助机构制定国家无人机规则。美国联邦航空管理局申明大多数商业无人机不能合法运营。机构计划宣布有关无人机如何与主要的航空公司在美国分享领空的规则。
 
Blacksburg测试中心的领导是Rose Monney。她说研究者们正和UAS做一些新项目。
 
“UAS可以完成载人航空器不能做到的。我们的首次试飞将是一架更大在国家领空上从未无人驾驶过的飞机。”
 
载人机上的航空信息传感器很常见。但是弗吉尼亚理工大学测试中心的研究员也在他们的无人机上安装了传感器。传感器记录航速和海拔高度,飞行高度。信息通过电子管发送到电脑以检测稳定性。然后所有的信息被发送到FAA。
 
联邦机构也可能其他设备上作出规定来确保更加安全,此设备是一个特殊的护目镜能使人看请飞行仿佛他就在无人机上一样。地勤人员在可通过这种视域来更好地引导无人机并使其避开航行轨道上的物体。
 
研究员Justin Stiltner说无人机也可能被用来做一些枯燥,恶劣,危险的工作。它们可以飞到辐射区域,或者飓风或者农田上空来检查玉米。Craig Woosley教授说农场研究是主要目的。
 
“我们需要在我们如何在农业方面做得更好,才能提高作物产量,这样才能激励我们朝着越来越多的科技方向发展。”
 
Roose Mooney认为无人机的使用是航空史上向前迈进的巨大一步。但是直到FAA发布新的规则前无人机的使用都不会发生改变。而这些在2015年前都不会发生。
