摘要一个高质量的惯性导航平台，最初是为TSR-2飞机开发的，现在正被气象研究飞行部门用来测量堪培拉PR-3飞机的垂直阵风速度和水平风切变。导出了计算垂直风和水平风的方程，并对垂直阵风和水平切变的测量精度进行了评估。文中还给出了飞机俯仰、侧滚和偏航时残差速度的测量结果，并给出了一个在平稳空气中水平直线飞行的速度实例。然后描述了使用该设备测量飞机通过湍流层下降时风切变和垂直阵风的小尺度变化，并给出了一系列此类飞行中的第一次飞行的结果。在目前的录音系统下，提取出的数据具有很高的可读性。
Abstract A high quality inertial navigation platform, originally developed for the TSR 2 aircraft, is now being used by the Meteorological Research Flight in order to measure vertical gust velocities and horizontal wind shear from a Canberra PR 3 aircraft. The equations are derived from which the vertical and horizontal winds are calculated, and an assessment is made of the accuracy of measurement which can be expected for vertical gusts and horizontal shear. Measurements of the residual error velocities which occur when the aircraft is made to pitch, roll and yaw are shown to lie within the theoretical limits, and an example of the velocities derived from a straight and level run in smooth air is also described. The use of this equipment to measure the small-scale variations in wind shear and vertical gusting when the aircraft descends through a layer of turbulence is then described, and the results of one of the first of a series of such flights are given. With the present recording system, the extracti...
