摘要
针对当前气象无人机皮托-静压管测风法存在精度低的问题,通过对现有测量模型的重新分析,考虑了飞机加速度这个物理量对测量结果的影响,提出了引入加速度的改进模型。定量计算结果显示,在不考虑加速度的情况下导致的风速相对误差较大,最大达到了50%,而引入加速度的改进模型可消除这部分误差,从而说明改进模型对提高风速测量精度的具有实际意义。
In view of the low measurement accuracy of Pitot static tube on UAV of wind speed, the original measurement model was re-analyzed. It was took into account that the impact of the aircraft acceleration on the measurement results and proposed an improved model which involved the acceleration. Quantitative calculation results showed that the relative error of wind speed in the case without considering the acceleration was up to 50%,while the new model with considering the acceleration could eliminate the error part.
