某型无人机飞行偏航异常的原因分析及改进

某型无人驾驶靶机是通过定向飞行控制来实现其靶廊飞行的,但在飞行试验时却出现了比较严重的靶廊飞行偏航现象。利用飞行动力学理论进行分析,对其偏航原因进行了排查和定位,确定了飞机偏航的主要原因是“V”尾安装的偏差所致,同时给出了相应的纠偏措施。试验验证的结果说明了偏航原因定位的准确性和纠偏措施的有效性。

Research and Improvement on Flight Leeway for a UAV Flight Test

A UAV target drone, which is designed to fly along a straight-line target path by directional flight control, appeared serious flight leeway phenomena in flight test. This flight leeway occurred in flight test is studied in this paper. By the theory of flight dynamics, the reason of flight leeway is analyzed. It is showed that the flight leeway resulted from"V"-tail mounted warp. The means to overcome the flight leeway is adopted, and the result of flight test is satisfactory after correcting.
