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.
