中文摘要:
      传统测风方法基于空速管等测风设备实现精确的实时测风。考虑降低成本,有些飞行器上没有安装空速管等测风设备。针对这种情况,文章提出一种通过航路转弯机动飞行实现测风的方法,即假设大气风场短时间内不变,基于速度三角形原理在转弯前、后的 2个航路上分别构建 2个方程,通过联解 2个方程得到大气风场信息。采用蒙特–卡洛法进行仿真,结果表明该方法简单有效、具有较高精度,为大气风场实时测量提供了一条新的思路。
英文摘要:
      The traditional wind measurement method is based on wind measurement equipment such as pitot tube to realizeaccurate real-time wind measurement. Considering the need to reduce costs and other requirements, some aircrafts are notequipped with wind measurement equipment. In view of this situation, in this paper, a method was proposed to realize windmeasurement through route turning maneuver flight. Assuming that the atmospheric wind field would not change in a shortperiod of time, two equations were respectively constructed on the two routes before and after turning based on the speedtriangle principle, and the atmospheric wind field information was obtained by solving the two equations in combination.The Monte Carlo method was used for simulation verification. The results show that the method is simple and effective withhigh accuracy, and a new idea for real-time measurement of atmospheric wind field was also provided.
