基于转动状态的气象无人机测风方法

Meteorological UAV wind method based on the rotational state

针对气象无人机转动探测时精度较低,本文通过引入等效位能和等效伯努利方程,得出了气象无人机转动空速方程;通过坐标变换,建立了空速和地速之间的角度关系,最后得出了气象无人机转动测风模型,并进行了仿真分析和数值试验。结果表明:转动测风模型测量精度较高满足气象无人机探测精度要求,为解决转动探测精度较低的问题,提供了参考。

Due to low detection accuracy of meteorological UAV in the rotational state,in this paper,with the did of effective potential and the equivalent Bernoulli＇s equation,we established meteorological UAV rotational state of airspeed equation,by coordinate transformation we set up the angle relationship between the airspeed and the groundspeed.Finally,we found the rotational state wind model of meteorological UAV,and performed the simulation and numerical experiments.Results indicated that the rotational wind model could get higher wind accuracy and meet the requirements of meteorological UAV rotational detection,so that it provides a reference to help solve the problem of low detection accuracy.
