本文介绍了为测量大气边界层湍流而研制的无人机的组成和使用方法。提供了一种从移动速度传感器数据计算与时间相关的风速的方法。建立的物理系统，以实现这种方法，使用五孔探头速度传感器描述沿着与方法，用于联合收割机数据从不同的机载传感器，以允许提取的风速作为时间和位置的函数。该方法是证明使用的数据从三个飞行的两个无人驾驶飞行器（UAV）测量低大气边界层从稳定过渡到对流状态。提出了几个数量，并显示出潜在的提取范围内的大气边界层统计。
This paper describes the components and usage of an unmanned aerial vehicle developed for measuring turbulence in the atmospheric boundary layer. A method of computing the time-dependent wind speed from a moving velocity sensor data is provided. The physical system built to implement this method using a five-hole probe velocity sensor is described along with the approach used to combine data from the different on-board sensors to allow for extraction of the wind speed as a function of time and position. The approach is demonstrated using data from three flights of two unmanned aerial vehicles (UAVs) measuring the lower atmospheric boundary layer during transition from a stable to convective state. Several quantities are presented and show the potential for extracting a range of atmospheric boundary layer statistics.
