基于非惯性运动状态的气象无人机测风方法研究

Based on the Non-Inertial Motion State Meteorological UAV Wind Method

针对气象无人机必须匀速直线飞行探测的条件限制,在气象无人机加速平动的状态下,通过引入等效压力,利用能量守恒定律,得出了非惯性运动状态的伯努利方程,建立了气象无人机非惯性运动状态的空速模型,并对非惯性运动状态空速模型的合理性进行了分析,最后进行了仿真实验。结果表明:当气象无人机处于加速平动状态时,本文所提出的气象无人机非惯性运动状态空速模型具有一定的实用价值。

Meteorological UAV must keep a linear uniform velocity in its monitoring flight.But to push through the detection in its accelerating translation state,we introduced an equivalent stress and considered the law of energy conservation to get out a Bernoulli equation for this non-inertial state.Based on form of this Bernoulli equation,we established an airspeed model of non-inertial state and analysed rationality of this airspeed model.The simulation and experiment results indicated that when the meteorological UAV flight in a state of accelerating translation,the airspeed model adapted to deal with the meteorological UAV flighting in non-inertial state and met the need for the detection accuracy.
