total pressure Pitor tube

Based on the research on sensitivity of geomagnetic declination on wind measurement by UAV(unmanned aerial vehicle) with Pitot-static tube,mathematical model of wind speed error to effect of geomagnetic declination is set up in virtue of wind measurement theory and error theory.

从无人机(unmanned aerial vehicle,UAV)皮托-静压管测风对磁偏角的敏感性出发,借助无人机皮托-静压管测风原理和误差理论,建立了磁偏角对测风影响的风速误差数学模型;通过仿真,分析了磁偏角对风速测量的影响和误差变化规律,并通过试验数据验证了仿真结论,为磁偏角的校正,提高风速测量精度提供了参考依据。
