中国首架国产应急物资远程运输无人机在陕西西咸新区成功进行初次飞行。

Local news website sxdaily.com reports that the drone can carry 15 kilos of payload as far as 80 kilometers in distance and drop material on a target accurately.

据当地新闻网站sxdaily.com报道,这架无人机可运载15千克的应急物资在80公里范围内进行精确投掷。

At present, domestic UAVs with low payloads and short flight ranges are not practical in the market.

目前，低负载短距离无人机已无法满足市场的需求。

The latest drone, with the largest upload and longest range among domestic UAVs, can transport emergency aid to disaster hit areas more efficiently than other means.

这部最新无人机是目前所有国产无人机中负载最大、传输距离最远的无人机。比起其他手段，无人机可以更有效地帮助灾区运送应急物资。

With two modes of engine operation, the drone can be used in various conditions. The gasoline-driven engine is fit for long-distance flight with heavy loads, while the electric engine is used in short-distance flight with light materials and high-altitude areas.

通过发动机的两种工作模式的切换，无人机可以被应用在多种场合。 汽油发动机适合长距离高负载地飞行，电力发动机常用于短距离低负载以及高海拔区域地飞行。

The project chief says they need to improve the automotive driving function and undertake further reliability tests.

该项目的总工程师说他们还需要优化无人机的自动化驾驶功能以确保能进行更远距离更稳定的测试。
