人工影响天气微型无人驾驶飞机用于复杂天气下人影作业，是可控和可回收探测器和播撒器。人工影响天气微型无人驾驶飞机系统由微型飞机、任务载荷（机载撒播装置和探测装置）及地面监视控制三部分构成。飞行前通过计算机给飞机上的机载控制系统设置航线,遥控起飞后可由机载控制系统控制,飞机按照预定航线进行自主飞行。在需要修改飞行方向时，也可通过遥控终端发出指令。在到达作业高度后，通过遥控终端发出指令，飞机开始播撒作业。在整个飞行过程中飞机不断探测大气温压湿和风，连续将探测资料和飞行数据发送给地面监视终端。通过试验验证了人工影响天气微型无人驾驶飞机飞行性能和探测能力：能够在携带1 kg播撒剂的情况下，飞达6 km的高度，作业半径20 km；能在雨天进行播撒作业和探测；飞机采用手掷起飞，对起飞的场地几乎没有要求；采用降落伞降落，可选择草地、农田降落。初步分析了对对流降水和雷电天气的适应能力。

Miniature robot aircraft (MRA) for weather modification is a kind of facilities used to operate under the complicated weather. It is composed of three parts, which are the miniature aircraft, the mission loading (the airborne seeding device and the detection device) and the ground monitor control terminal. Before flight path is designed for the airborne control system. The aircraft can be commanded after taking off, and the aircraft aviates automatically according to the preconcerted flight path. We can also send instructions by the remote control terminal when the route should be modified. After reaching the altitude of operation and receiving instruction from the remote control terminal, the aircraft commences seeding operation. During flight course, the aircraft detects temperature, humidity, pressure and wind of the atmosphere and send, the collecting data continuously to supervision terminal on the ground. Through tests, the flight performance and the detection capability of MRA for weather modification are proved. It can fly to the altitude of 6000m with the seeding material which weighs 1000g and its operation radius can reach 25km. The operation can be done in rainy condition. The MRA takes off by tossing and needs little requirement for the take-off field. Grassland or farmland is suitable for landing by parachute. Adaptive capability under convective precipitation or thunderbolt weather has been analyzed primarily.
